# Best Walmart Protein Powder > The best Walmart protein powder ranked by cost per 25 g of protein, from Six Star and Body Fortress to Gold Standard, plus Equate, Walmart+ and online tips. - **URL**: https://www.best-proteinpowder.com/best-walmart-protein-powder/ - **Updated**: 2026-11-06 - **Author**: [Best Protein Powder Editorial Team](https://www.best-proteinpowder.com/authors/editorial-team/) - **Publisher**: [Best Protein Powder](https://www.best-proteinpowder.com/) --- Seven powders sold at Walmart and on Amazon, ranked by how much protein you get for your money, then by testing and formula. Plus what Equate's own whey is worth. **How we rank:** We judge every powder on the label, not the marketing: protein per scoop, cost per 25 g of protein, the full ingredient list and third-party testing. No paid placements, and commission never sets a ranking. [Read our methodology](https://www.best-proteinpowder.com/how-we-test/) The best Walmart protein powder for most people on a budget is a big tub of Six Star 100% Whey Protein Plus or Body Fortress Super Advanced Whey: 30 g of protein per scoop, per their labels, and the lowest cost per gram of any name-brand powder on the shelf. Optimum Nutrition Gold Standard in the 5 lb tub costs a little more and gives you a leaner, denser whey, and Muscle Milk Genuine is the pick if you need a verified sport certification. Walmart's range is huge but uneven, so we also explain how to compare tubs, when Walmart.com beats the store, and whether Equate's own whey is worth buying. ## Our Top Picks | Award | Product | Why | | --- | --- | --- | | Lowest Cost per 25 g | [Six Star 100% Whey Protein Plus](https://www.best-proteinpowder.com/best-walmart-protein-powder/#six-star-100-whey-protein-plus) | The cheapest decent whey you will reliably find at Walmart.

Walmart Protein Powders Compared at a Glance Here is the short version first. The table lists the seven powders we ranked, plus Walmart's own Equate whey for reference, with the label figures that matter and a price tier based on cost per 25 g of protein at the shelf and online prices we saw in early November 2026. Budget means roughly the cheapest third of the market, mid means middle of the road, and premium means you are paying for something other than raw protein value. Walmart prices move with Rollbacks, flavor and store, so we use tiers rather than dollar figures that would be stale by the time you read this. | Product | Protein / serving | Calories | Price tier (per 25 g) | Certification | | --- | --- | --- | --- | --- | | Six Star 100% Whey Protein Plus | 30 g | About 170-180 | Budget | Brand claim only | | Body Fortress Super Advanced Whey | 30 g per scoop | About 180 | Budget | NSF Contents claim, unverified | | Optimum Nutrition Gold Standard | 24 g | About 120 | Budget (5 lb) to mid | Brand claim; check flavor | | Premier Protein 100% Whey | 30 g (2 scoops) | About 150 | Mid | None confirmed | | Muscle Milk Genuine | 32 g | About 270 | Mid | NSF Certified for Sport | | Orgain Organic Plant-Based | 21 g (2 scoops) | About 150 | Mid to premium | USDA Organic only | | Isopure Zero Carb | 25 g | About 110 | Premium | None confirmed | | Equate Whey (Walmart only, not ranked) | About 24 g | About 120 | Budget | None found | All nutrition figures come from the brands' labels at the time of writing and vary by flavor. Three patterns stand out. First, the cheapest protein per gram at Walmart comes from big tubs of budget whey blends, which is why Six Star and Body Fortress sit at the top. Second, those budget blends get their 30 g scoops partly by being large scoops: a 45-47 g scoop that delivers 30 g of protein is only around 64-67% protein, with the rest mostly maltodextrin, flavor and gums. Gold Standard and Isopure deliver less protein per scoop but much more protein per gram of powder. Third, the spread between cheapest and dearest is wide. At Costco every tub is big, so even premium brands land at a decent cost per gram. Walmart sells everything from 1 lb tubs to 5 lb tubs, and the same brand can be a bargain in one size and poor value in another. Tub size matters as much as brand on this shelf, and we flag the size that makes each pick worth buying. If you only read one line: buy the big tub of Six Star or Body Fortress for the lowest cost, Optimum Nutrition Gold Standard in the 5 lb size if you want a cleaner, denser whey for a little more, and Muscle Milk Genuine if you need a verified banned-substance certification. Everything else solves a narrower problem, such as calories, carbohydrate or dairy. ## 2. How We Ranked Walmart Protein Powder This is a label-and-price analysis, not a taste test. We did not buy and drink every tub. We started from the protein powders Walmart lists in its protein and fitness aisle and on Walmart.com, kept the ones that are also sold on Amazon (our links go to Amazon, so a pick you cannot click through to is no use to you), checked each brand's current nutrition label and certification claims, and ranked them by cost per 25 g of protein first, then by testing and formula. Where we mention taste or mixing, we are reporting what buyers commonly say. Our full approach is on our [how we test](https://www.best-proteinpowder.com/how-we-test/) page. Cost per 25 g of protein is the only fair way to compare tubs. Multiply servings per container by grams of protein per serving to get total protein, divide the price by that total, then multiply by 25. That turns a 24.5 oz tub of two-scoop 30 g servings and a 5 lb tub of 24 g scoops into numbers you can compare directly. Walmart's shelf tags and website show a unit price per ounce, which is helpful but measures powder, not protein. A cheaper price per ounce can still be the more expensive protein if the scoop is padded with carbohydrate. We rounded results into budget, mid and premium tiers because Walmart prices shift constantly. Rollbacks, clearance tags, online-only prices and marketplace sellers can all move a tub up or down a tier for a few weeks. We did not quote exact Walmart prices because we could not confirm they would hold, and you should check the live price on the day you buy. After cost, we weighed third-party testing. NSF Certified for Sport and Informed Sport test for banned substances and are the standards that matter to drug-tested athletes. A vague 'banned-substance tested' line on a tub, without a named certifier you can look up, counts for much less. Finally, we looked at formula: protein per calorie, added sugar, sweeteners and how much of the scoop is actually protein. ## 3. The Best Protein Powders at Walmart, Ranked Ranked by cost per 25 g of protein at the Walmart and Amazon prices we saw in early November 2026, then by certification and formula. Nutrition figures are from each brand's label at the time of writing and vary by flavor. Every pick is sold at Walmart and also on Amazon, which is where our links go. Walmart stock varies by store, and some sizes and flavors are online only. ### 1. Six Star 100% Whey Protein Plus **Award:** Lowest Cost per 25 g | **Type:** Whey concentrate, isolate and hydrolyzed whey blend - **Protein / serving:** 30 g (label) - **Calories:** About 170-180 - **Third-party tested:** Brand claim; certifier not named - **Best for:** Lowest cost per gram Six Star is one of the most widely stocked powders in Walmart's protein aisle, sold in roughly 1.8 lb tubs and a larger 4.1 lb size, including Kellogg's cereal flavors. Per the brand's label at the time of writing, one 46-48 g scoop gives 30 g of protein, about 170-180 calories, 8 g of carbohydrate and 2 g of sugar, varying by flavor. In the big tub it is usually the cheapest name-brand protein per gram on the shelf. **Bottom line:** The cheapest decent whey you will reliably find at Walmart. Buy the big tub, and accept a few extra carbs for the price. **Pros:** - Budget-tier cost per 25 g of protein, especially in the 4.1 lb tub - 30 g of protein per scoop, per the label - Wide flavor range, including Froot Loops and Frosted Flakes versions - Also sold on Amazon, where Subscribe and Save can undercut the shelf **Cons:** - Only about 64% protein by weight, because the scoop includes maltodextrin - The brand says 'banned-substance tested' but does not name a certifier - Sucralose in most flavors [Check price on Amazon](https://www.amazon.com/dp/B09SYB2ZQ2?tag=sktiger-20&linkCode=ll1) ### 2. Body Fortress Super Advanced Whey Protein **Award:** Best Walmart Staple | **Type:** Whey concentrate and isolate blend - **Protein / serving:** 30 g per scoop (label) - **Calories:** About 180 - **Third-party tested:** NSF Contents claim, unverified - **Best for:** Reliable in-store budget pick Body Fortress has been a Walmart shelf fixture for years and is sold there in about 1.78 lb and 3.9 lb tubs. Per the label at the time of writing, one 45 g scoop of chocolate gives 30 g of protein, 180 calories, 7 g of carbohydrate and 3 g of sugar; the front of the tub advertises 60 g because it quotes a two-scoop serving. The label carries an NSF Contents Certified claim, which we could not confirm in NSF's public registry. **Bottom line:** A solid budget whey that is nearly always in stock. Read the serving line, then dose by the single scoop. **Pros:** - Budget-tier cost per 25 g in the 3.9 lb tub - 30 g of protein per single scoop, per the label - Added vitamin D and zinc - Easy to find in most Walmart stores and on Amazon **Cons:** - The '60 g protein' on the front is a two-scoop, 360-calorie serving - Contains maltodextrin plus two artificial sweeteners - NSF Contents Certified claim not verified in the NSF registry [Check price on Amazon](https://www.amazon.com/dp/B0C6R7WH62?tag=sktiger-20&linkCode=ll1) ### 3. Optimum Nutrition Gold Standard 100% Whey **Award:** Best Name-Brand Whey | **Type:** Whey blend (isolate listed first) - **Protein / serving:** 24 g (label, varies by flavor) - **Calories:** About 120 - **Third-party tested:** Brand claim; check flavor - **Best for:** Everyday whey, mixing Gold Standard is the reference whey of the supplement world, and Walmart carries it from about 1.5 lb tubs up to 5 lb, with a wider flavor range online than in most stores. Per the label at the time of writing, a 31 g scoop of Double Rich Chocolate gives 24 g of protein, about 120 calories, 3 g of carbohydrate and 1 g of sugar. It is the best protein-to-calorie ratio of the mainstream blends here. **Bottom line:** The safest everyday pick at Walmart if you buy the 5 lb tub. In small tubs you are paying a premium for the name. **Pros:** - About 77% protein by weight, far denser than the budget blends - Long track record and widely reported to mix with a spoon - 5 lb tub brings the cost per 25 g toward the budget tier - Dozens of flavors across Walmart.com and Amazon **Cons:** - Mid-tier cost per 25 g in small tubs - The brand says it is banned-substance tested; confirm the exact flavor with the certifier - Stores usually stock only a few flavors [Check price on Amazon](https://www.amazon.com/dp/B000GISTZ4?tag=sktiger-20&linkCode=ll1) ### 4. Premier Protein 100% Whey Protein Powder, Chocolate Milkshake **Award:** Best for Premier Shake Fans | **Type:** Whey isolate and concentrate blend - **Protein / serving:** 30 g (label) - **Calories:** About 150 - **Third-party tested:** None confirmed - **Best for:** Lean 30 g serving Premier's powder is the tub version of the ready-to-drink shakes that dominate Walmart's protein aisle, sold in a 24.5 oz chocolate tub and a 23.3 oz vanilla. Per the label at the time of writing, a 41 g serving of about two scoops gives 30 g of protein, 150 calories, 3 g of carbohydrate and 1 g of sugar. It is the leanest 30 g serving among the Walmart blends. **Bottom line:** A good buy if you like Premier's shakes and want them cheaper per gram. Not the value play. **Pros:** - 30 g of protein for about 150 calories, per the label - Familiar Premier shake flavor profile - Isolate listed first in the protein blend **Cons:** - Mid-tier cost per 25 g, because tubs are small at about 17 servings - The 30 g serving is two scoops, so tubs empty fast - No third-party certification we could confirm [Check price on Amazon](https://www.amazon.com/dp/B06Y5ZG66K?tag=sktiger-20&linkCode=ll1) ### 5. Muscle Milk Genuine Protein Powder **Award:** Best Certified Pick | **Type:** Milk protein blend (whey, casein) - **Protein / serving:** 32 g (label) - **Calories:** About 270 - **Third-party tested:** NSF Certified for Sport - **Best for:** Tested athletes, bulking Muscle Milk Genuine sits on most Walmart shelves in a 1.93 lb canister, with a 4.94 lb canister online. Per the label at the time of writing, a 70 g serving of chocolate gives 32 g of protein, about 270 calories, 20 g of carbohydrate and 2 g of sugar, from whey and milk protein concentrates plus caseinates. Its chocolate, vanilla and other core flavors appear in the NSF Certified for Sport registry. **Bottom line:** The Walmart pick for drug-tested athletes and anyone who wants a filling shake; not for tight calorie budgets. **Pros:** - NSF Certified for Sport, verified in the NSF registry for core flavors - 32 g of protein per serving from a slower-digesting milk protein blend - Creamier, more filling shake than a lean whey **Cons:** - About 270 calories and 20 g of carbohydrate per serving - Mid-tier cost per 25 g, with only about 12 servings in the small canister - Contains added oils, creamer and two artificial sweeteners [Check price on Amazon](https://www.amazon.com/dp/B0B5L5T76W?tag=sktiger-20&linkCode=ll1) ### 6. Orgain Organic Protein Plant-Based Powder **Award:** Best Plant-Based | **Type:** Organic pea, brown rice, mung bean and chia blend - **Protein / serving:** 21 g (label) - **Calories:** About 150 - **Third-party tested:** USDA Organic; no sport certification - **Best for:** Dairy-free shoppers Orgain is the plant protein Walmart stocks most consistently, usually in a 2.03 lb tub and in two-packs online. Per the label at the time of writing, a two-scoop, 46 g serving of Creamy Chocolate Fudge gives 21 g of protein and about 150 calories with under 1 g of sugar. It is USDA Organic and dairy-free and widely described as one of the easier plant shakes to drink. **Bottom line:** The realistic dairy-free buy at Walmart. Choose it for taste and diet, not for protein value. **Pros:** - Dairy-free and USDA Organic - Widely reported as easy to drink for a plant protein - Stocked in most stores and on Amazon **Cons:** - Only 21 g of protein per two scoops, so the real cost per 25 g is mid-to-premium - Higher in sodium and carbohydrate than the wheys - Some package versions use erythritol, which upsets some stomachs [Check price on Amazon](https://www.amazon.com/dp/B00J074W7Q?tag=sktiger-20&linkCode=ll1) ### 7. Isopure Zero Carb Protein Powder **Award:** Leanest Option | **Type:** Whey protein isolate - **Protein / serving:** 25 g (label) - **Calories:** About 110 - **Third-party tested:** None confirmed - **Best for:** Keto, lactose-sensitive Isopure Zero Carb is sold at Walmart mostly online, in 1 lb to 3 lb tubs and several flavors, with a smaller in-store selection. Per the label at the time of writing, a 31 g scoop of Creamy Vanilla gives 25 g of protein and about 110 calories with zero carbohydrate and zero sugar, from whey isolate alone. It is the most protein-dense and the most expensive powder on this list. **Bottom line:** Worth the premium only for strict low-carb diets or lactose trouble; otherwise Gold Standard does the job for less. **Pros:** - 25 g of protein for about 110 calories, with no carbohydrate or sugar - Pure isolate, so very little lactose - Mixes thin and clear, per buyer feedback **Cons:** - Premium cost per 25 g, the highest here - Sucralose plus an added vitamin blend - No sport certification we could confirm [Check price on Amazon](https://www.amazon.com/dp/B000E95HP0?tag=sktiger-20&linkCode=ll1) ## 4. What Protein Powder Does Walmart Sell? Walmart's range is far bigger than a warehouse club's and far more mainstream than a supplement store's. A typical Supercenter protein aisle carries a dozen or more powders, built around a few anchors: Body Fortress, Six Star, Optimum Nutrition Gold Standard, Premier Protein, Muscle Milk, Pure Protein, Isopure, Orgain and Walmart's own Equate whey. Larger stores add BSN Syntha-6, MuscleTech, Dymatize and assorted mass gainers. Smaller neighborhood stores may stock only a handful. Walmart.com is a different animal. It lists thousands of protein products, but many are sold by marketplace sellers rather than by Walmart itself. Those listings can carry odd sizes, multipacks, older label versions and prices that bear no relation to the shelf. When a product page says 'sold and shipped by Walmart.com', you are buying from Walmart's own inventory. When it names another seller, you are buying from a third party, and expiry dates, storage and return handling depend on them. That is not automatically bad, but it is worth noticing before you pay a premium. Flavors and sizes vary by store, too. A store might carry Gold Standard only in Double Rich Chocolate and Vanilla Ice Cream, while the website lists most of the brand's range. Body Fortress and Six Star tend to be stocked in the most sizes in store, because they are budget staples. Isopure and Orgain are often thinner on the shelf and better stocked online. Every pick on our list is sold at Walmart and also on Amazon. That matters because our links go to Amazon, and because comparing the two is the simplest way to know whether a Walmart price is good. If you are deciding between stores, our [Costco protein powder rankings](https://www.best-proteinpowder.com/best-costco-protein-powder/) and [Target protein powder guide](https://www.best-proteinpowder.com/best-target-protein-powder/) use the same cost-per-gram method, so the numbers line up. ## 5. Is Equate Protein Powder Any Good? Equate is Walmart's store brand, and it does sell a whey protein powder: a 24 oz tub of about 22 servings in Smooth Vanilla and Rich Chocolate. Walmart's listing says each serving provides 24 g of protein and names whey protein isolate as the first ingredient, and third-party nutrition databases put a scoop of about 30-31 g at roughly 120 calories. That is almost exactly the profile of Optimum Nutrition Gold Standard, at a lower shelf price for the tub size. On the numbers we could check, Equate whey lands in the budget tier for cost per 25 g of protein. In the 24 oz size it is competitive with Six Star and Body Fortress in their small tubs, and it does it with a leaner scoop: about 24 g of protein in roughly 30 g of powder, versus 30 g of protein in 45-47 g for the budget blends. If you want a Gold Standard-style whey without the Gold Standard price, it is worth a look. The caveats are about transparency and availability. Walmart does not name the manufacturer on the listing, we found no NSF Certified for Sport or Informed Sport listing for it, and the full supplement facts panel was not reliably available online when we checked, so confirm the label on the tub. House brands rarely carry sport certifications, so this is normal, but it means you are relying on Walmart's own supplier standards rather than an independent tester. We did not rank Equate for one practical reason: it is a Walmart-exclusive store brand and is not sold through Amazon, which is where our product links go. That is not a judgment on quality. If you are standing in the aisle and the 24 oz tub is on the shelf, it is a reasonable budget buy for a recreational lifter. Drug-tested athletes should pick a certified powder instead. Equate also sells ready-to-drink protein shakes, which we cover in the final section. ## 6. Cost per 25 g of Protein at Walmart Protein per dollar is where Walmart can be excellent or mediocre depending on what you pick up. The largest tubs of budget whey are among the cheapest protein you can buy anywhere in a regular store. The smallest tubs of premium isolates are some of the dearest. Within our list the order is fairly stable: Six Star and Body Fortress in big tubs first, Equate and Gold Standard's 5 lb tub close behind, then Premier and Muscle Milk, with Orgain and Isopure at the top end. > **THE RULE** > > **Compare cost per 25 g of protein, not price per ounce.** > > Servings per container times grams of protein per serving gives total protein. Divide the price by that, then multiply by 25. Walmart's unit price per ounce measures powder, so a carb-heavy scoop can look cheap and still cost more per gram of protein. Size is the single biggest lever. Gold Standard in a small tub is solidly mid tier; in the 5 lb tub it drops toward budget. Six Star's 4.1 lb tub is noticeably cheaper per gram than its 1.8 lb tub in the prices we saw. Muscle Milk's larger canister is better value than the 1.93 lb can on most shelves. If you have found a powder you like, the big size nearly always pays off, provided you will finish it before the best-by date. Two-scoop servings hide cost. Premier and Orgain both quote their protein per two scoops, so their tubs hold fewer servings than the weight suggests. Body Fortress quotes 60 g of protein on the front for a two-scoop serving, which makes a 1.78 lb tub look like it holds fewer servings than it really does at one scoop. Always work from servings per container and grams of protein on the panel, not from the front of the tub. Rollbacks shift the order more than anything else. A Rollback on Gold Standard or Muscle Milk can briefly beat the budget blends, and Amazon's Subscribe and Save sometimes undercuts the Walmart shelf on Six Star and Body Fortress. For a wider look at cheap protein across every retailer, our [best cheap protein powder](https://www.best-proteinpowder.com/best-cheap-protein-powder/) rankings run the same maths on brands Walmart does not carry. ## 7. In Store vs Walmart.com vs Amazon Buying in store has two real advantages: you can check the best-by date and the exact flavor before you pay, and you can see the shelf tag price, which sometimes beats the website. Clearance stickers on discontinued flavors can be especially good value. The downside is selection, since your store may stock only a few flavors of each brand and the big tubs sell out first. Walmart.com has the widest range, including sizes and flavors that never reach your store. Free pickup lets you order online and collect without paying for shipping. The thing to watch is the seller: stick with listings sold and shipped by Walmart.com where you can, and treat marketplace listings with unusually high prices or very old label versions with caution. Read the size and serving count carefully, because multipacks and odd sizes make quick price comparisons misleading. ### Walmart+ notes Walmart+ is Walmart's paid membership, listed at $12.95 a month or $98 a year when we checked, with a free or low-cost trial offered at times. Per Walmart's published terms, members get free shipping on eligible items shipped by Walmart without the usual order minimum, and free delivery from local stores on orders above a basket minimum. Non-members get free shipping on orders over $35. Terms change, delivery is not available everywhere, and marketplace items may be excluded, so check the current terms before you count on any of it. For protein powder alone, Walmart+ rarely pays for itself. One big tub a month easily clears the $35 free-shipping threshold for non-members, so the membership only makes sense if you already order groceries for delivery. Amazon is the other comparison: Subscribe and Save discounts on Six Star, Body Fortress and Gold Standard can beat Walmart's price, and our guide to [buying protein powder on Amazon](https://www.best-proteinpowder.com/amazon-protein-powder/) covers seller checks and deal timing there. ## 8. Testing and Certification on the Walmart Shelf Testing claims on Walmart's shelf range from rigorous to meaningless, and the tub alone will not tell you which. The strongest credential among our picks is Muscle Milk Genuine, whose core flavors appear in the NSF Certified for Sport registry. That program tests for more than 280 banned substances and checks that the label matches the contents, and it is the standard most US professional and college sports bodies recognize. Body Fortress carries an NSF Contents Certified claim on its label. That is a different and narrower program than NSF Certified for Sport, focused on whether contents match the label rather than on banned substances, and we could not find the product in NSF's public registry. Six Star and Optimum Nutrition both state that their powders are banned-substance tested without naming the certifier on the product page we checked. Premier, Isopure and Equate carry no sport certification we could confirm, and Orgain carries USDA Organic, which governs farming practices and says nothing about contaminants. If you are drug tested, the rule is simple: search the exact product and flavor in the NSF Certified for Sport or Informed Sport database before you buy, and keep the lot number. A positive test is your responsibility regardless of what the tub said. That applies just as much to a teenager who competes, and our [is protein powder safe](https://www.best-proteinpowder.com/is-protein-powder-safe/) guide explains where the real contamination risks lie. For everyone else, certification is a tiebreaker rather than a requirement. A large, established brand with a documented quality system is a reasonable buy without a badge. Plant proteins tend to carry more heavy metals than whey on average, which is worth knowing if you use Orgain daily; our guide to [protein powder without heavy metals](https://www.best-proteinpowder.com/best-protein-powder-without-heavy-metals/) covers the testing data in detail. If you have kidney disease, are pregnant or take regular medication, check with a doctor or registered dietitian before adding a daily shake. None of this is medical advice. ## 9. Which Walmart Protein Powder Should You Buy? ### If you just want the cheapest decent whey Buy the largest tub of Six Star or Body Fortress you can find, and pick whichever is cheaper per 25 g that week. Both give 30 g of protein per scoop, per the label. If you prefer a leaner scoop and your store has it, Equate whey is the Walmart-only alternative at a similar cost per gram. ### If you want a cleaner, denser whey Buy Optimum Nutrition Gold Standard in the 5 lb tub. It has fewer carbohydrates per gram of protein than the budget blends, a long track record and the widest flavor range, and the big size keeps the cost per gram reasonable. Our [Optimum Nutrition review](https://www.best-proteinpowder.com/optimum-nutrition-protein-powder-review/) covers the rest of the brand's range. ### If you compete in a tested sport Buy Muscle Milk Genuine and confirm your flavor in the NSF Certified for Sport registry. It is the only pick here with a sport certification we could verify. Accept that it carries more calories and carbohydrate than a lean whey, which suits a bulking phase better than a cut. ### If you are cutting, low carb or lactose sensitive Isopure Zero Carb has the best protein per calorie and no carbohydrate, and as a pure isolate it carries very little lactose. Premier's powder is the cheaper compromise at 30 g of protein for about 150 calories. Our [whey vs whey isolate guide](https://www.best-proteinpowder.com/whey-vs-whey-isolate/) explains why isolates sit better with many people who bloat on regular whey. ### If you avoid dairy Orgain is the plant option Walmart stocks most reliably. Take a slightly larger serving if you are using it to build muscle, since 21 g per two scoops is light. If you are new to all of this, our sibling guide to the [best protein powder for beginners](https://www.best-proteinpowder.com/best-protein-powder-for-beginners/) walks through choosing a first tub, and our [how much protein do I need](https://www.best-proteinpowder.com/how-much-protein-do-i-need/) guide sets daily targets so you know how many shakes you actually need. ## 10. Other Walmart Protein Products Worth Knowing Walmart sells a lot of protein that is not powder, and some of it competes on convenience if not on cost. Ready-to-drink shakes are the biggest category: Premier Protein's 30 g shakes, Muscle Milk, Pure Protein, Fairlife Core Power and Equate's own protein shakes, usually in 4-packs, 12-packs and larger cases. Bought by the case they can be competitive, but per gram of protein they nearly always cost more than a big tub of powder. If convenience is the reason you skip your shake, though, a case of bottles in the fridge may be the better buy. Our [best protein drink](https://www.best-proteinpowder.com/best-protein-drink/) guide ranks the main options. Equate's shakes deserve a specific note because people searching for Equate protein powder often find them first. They are ready-to-drink nutrition shakes rather than powder, and the line includes both high-protein shakes and general nutrition drinks closer to a meal supplement. Read the label carefully: some are built for protein, others for calories and vitamins, and the protein per bottle varies widely across the range. Collagen peptides such as Vital Proteins are also widely stocked. Collagen mixes invisibly into coffee, but it is an incomplete protein, low in leucine and missing tryptophan, so it is not a substitute for whey or a good plant blend if your goal is muscle. We left it out of the ranking for that reason. Mass gainers such as Optimum Nutrition Serious Mass, BSN True Mass and Muscle Milk's gainer line sit next to the powders and are easy to grab by mistake. They are mostly carbohydrate, with several hundred calories per serving, and are a poor buy unless you are deliberately trying to gain weight. Meal replacement shakes are another category again; our sibling guide to the [best meal replacement shake](https://www.best-proteinpowder.com/best-meal-replacement-shake/) covers those. ## 11. Common Mistakes to Avoid ### Trusting the unit price per ounce Walmart's shelf tags and website show price per ounce of powder, not per gram of protein. A budget blend that is a third carbohydrate can win on price per ounce and lose on protein. Use servings per container and protein per serving from the panel, then compare cost per 25 g. ### Reading the front of the tub instead of the panel Body Fortress advertises 60 g of protein and Premier and Orgain quote two-scoop servings. Front-of-tub numbers are often based on large servings. Check the serving size in grams, the servings per container and the calories on the supplement facts panel before comparing anything, or you will misjudge the real value. ### Buying from a marketplace seller by accident Many Walmart.com listings are sold by third parties, sometimes at inflated prices or with older label versions. Look for 'sold and shipped by Walmart.com' when possible, check the size and serving count, and compare against the shelf price and Amazon before paying more than you expected. ### Grabbing a mass gainer for a protein powder Gainers sit right next to the protein powders and look similar. Most are mainly carbohydrate with several hundred calories per serving and modest protein per dollar. Unless you are deliberately trying to gain weight, check that protein, not carbohydrate, is the main macronutrient listed on the label. ### Treating a vague testing claim as certification Phrases like 'banned-substance tested' mean little without a named certifier you can look up. If you are drug tested, search the exact product and flavor in the NSF Certified for Sport or Informed Sport database, and keep your lot number, before relying on any tub. ## 12. Frequently Asked Questions ### What is the best protein powder at Walmart? For lowest cost, the big tubs of Six Star 100% Whey Protein Plus and Body Fortress Super Advanced Whey usually give the cheapest protein per gram, with 30 g per scoop per their labels. Optimum Nutrition Gold Standard in the 5 lb tub is the better-formulated everyday whey, and Muscle Milk Genuine is the pick if you need NSF Certified for Sport. ### Does Walmart have its own protein powder? Yes. Equate, Walmart's store brand, sells a whey protein powder in a 24 oz tub of about 22 servings in vanilla and chocolate. Walmart's listing says it gives 24 g of protein per serving with whey isolate as the first ingredient. Walmart does not name the manufacturer, and we found no sport certification for it. ### Is Equate protein powder good? On the label it looks like a normal, lean whey, very close to Optimum Nutrition Gold Standard on protein and calories, and it lands in the budget tier for cost per gram. The trade-offs are that the manufacturer is not named, we could not find a third-party sport certification, and it is only sold at Walmart rather than on Amazon. ### Is protein powder cheaper at Walmart or Amazon? It depends on the product and the week. Walmart's shelf prices and Rollbacks are often competitive on budget brands like Six Star and Body Fortress, while Amazon's Subscribe and Save can beat them on the same tubs. Work out cost per 25 g of protein at both on the day you buy, using the same tub size. ### Is Body Fortress good protein powder? For the price, yes. Per the label, one 45 g scoop gives 30 g of protein for about 180 calories, and the 3.9 lb tub is in the budget tier per gram. It uses maltodextrin and two artificial sweeteners, and its NSF Contents Certified claim is not the same as NSF Certified for Sport, so tested athletes should look elsewhere. ### Which Walmart protein powder is third-party tested? Muscle Milk Genuine's core flavors appear in the NSF Certified for Sport registry, which made it the only pick with a sport certification we could verify. Body Fortress carries an NSF Contents claim we could not confirm, and Six Star and Optimum Nutrition say they are banned-substance tested without naming a certifier on the pages we checked. ### Is Walmart+ worth it for buying protein powder? Usually not for powder alone. Non-members already get free shipping on orders over $35, which one large tub typically covers, and in-store pickup is free. Walmart+ makes more sense if you already order groceries for delivery regularly. Check current membership terms, since pricing and delivery minimums change and vary by location. ## Related Protein Powder Rankings - [Best Costco Protein Powder](https://www.best-proteinpowder.com/best-costco-protein-powder/): Kirkland, Gold Standard and Ascent ranked by cost per 25 g of protein in the warehouse. - [Best Cheap Protein Powder](https://www.best-proteinpowder.com/best-cheap-protein-powder/): The cheapest protein per gram across every retailer, not just one store's shelf. - [Best Target Protein Powder](https://www.best-proteinpowder.com/best-target-protein-powder/): What Target stocks, from Premier to Orgain, compared on the same cost-per-gram basis. ## The Bottom Line Walmart can be one of the cheapest places to buy protein powder, but only if you buy the right size of the right tub. The big tubs of Six Star and Body Fortress are the value plays, Gold Standard's 5 lb tub is the better-made everyday whey, and Muscle Milk Genuine is the one to choose if a verified sport certification matters. Equate's whey is a fair budget buy if your store has it. Whatever you pick, ignore the front of the tub and the price per ounce. Work out cost per 25 g of protein from the panel, check who is selling it online, and compare against Amazon on the day. Powder is a convenient way to fill a protein gap, not the foundation of a diet. ## More in Protein Powder Rankings Guides in this category that pair with what you just read. - [Best Costco Protein Powder](https://www.best-proteinpowder.com/best-costco-protein-powder/) - [Best Aldi Protein Powder](https://www.best-proteinpowder.com/best-aldi-protein-powder/) - [Best Protein Powder on Amazon](https://www.best-proteinpowder.com/amazon-protein-powder/) - [Best Cheap Protein Powder](https://www.best-proteinpowder.com/best-cheap-protein-powder/) About the Author [Best Protein Powder Editorial Team](https://www.best-proteinpowder.com/authors/editorial-team/), Supplements Desk The editorial team reads the label, the certificate and the price per gram of protein before a powder gets near a ranking -- and says plainly when a cheaper tub does the same job.
