Six pumpkin seed protein powders compared on what the label really delivers per gram, with an honest look at lysine, minerals, the green color and what 25 g of protein costs.

**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/)

Pumpkin seed protein is the plant protein for people who cannot or will not use pea, soy or dairy. It is a pressed, milled seed powder with one ingredient, about 55 to 67 percent protein by weight, and more magnesium, iron and zinc per scoop than almost any other powder. It also has real limits: it is low in lysine, it costs more than pea, it turns your shake green, and a scoop often gives 10 to 20 g of protein rather than 25. Here is how to choose one, and when a blend makes more sense.

## 1. What Pumpkin Seed Protein Actually Is

Pumpkin seed protein is made from hulled pumpkin seeds, the green pepitas you see in trail mix. The seeds are pressed to remove most of their oil, and the pressed cake that is left is milled and sifted into a fine powder. Most brands describe the process as cold-pressed or simply pressed, with no solvent extraction. The result is a single-ingredient food that is mostly protein, with a little residual fat, some fiber and a meaningful dose of minerals.

That puts it in the same family as [hemp protein](https://www.best-proteinpowder.com/best-hemp-protein-powder/): a minimally processed seed powder rather than a refined isolate. The difference is concentration. Typical hemp powders land near 50 percent protein by weight, while the pumpkin seed powders in this guide run from about 55 to 67 percent, per their labels. That is less than a pea isolate, which is usually 80 percent or more, but enough to make pumpkin seed a usable protein powder rather than just a smoothie booster.

The labels tell you very little about how a brand gets there. Some sift more of the fiber out, which raises protein per gram; others leave more of the seed intact, which raises fat, fiber and calories. That is why two powders made from the same seed can list 10 g of protein in a 15 g serving and 18 g in a 30 g serving. Neither is wrong. They are slightly different products, and the only fair way to compare them is protein per gram of powder.

Pumpkin seed protein is rarely the headline ingredient in mainstream shakes. When it appears on a big-brand label, it is usually as a supporting protein in a pea-led blend, as in Truvani, OWYN and several greens-and-protein products. Single-ingredient pumpkin protein is a smaller niche, sold mostly by organic specialty brands. That is part of why the choice is narrow and prices vary so widely between bags that look almost identical.

This guide sits alongside our guides to [pea protein](https://www.best-proteinpowder.com/best-pea-protein-powder/), [brown rice protein](https://www.best-proteinpowder.com/best-brown-rice-protein-powder/) and hemp. If you are choosing between the plant proteins rather than between pumpkin brands, read the comparison sections below first, then check our [plant-based protein powder](https://www.best-proteinpowder.com/best-plant-based-protein-powder/) roundup for the finished blends that combine several of them.

## 2. Protein per Scoop: Why the Labels Look So Different

Pumpkin seed protein labels are hard to compare at a glance because serving sizes range from 15 g to 36 g. NOW lists 10 g of protein in a 15 g serving, Micro Ingredients 18 g in about 30 g, Probase 19 g in 30 g, and Sprout Living 20 g in 32.5 g for the unflavored version and 20 g in 36 g for vanilla, all per the labels at the time of writing. On the front of the jar, NOW looks like the weakest. Per gram, it is the strongest.

The table below converts every label to the same question: how much powder, and how many calories, does it take to get 25 g of protein? This is the number to use when you compare pumpkin seed with whey or pea, and when you plan a shake. A typical pea isolate needs about 30 g of powder for 25 g of protein. Most pumpkin seed powders need about 38 to 45 g.

| Powder | Protein per serving (label) | Powder for 25 g protein | Calories at 25 g protein |
| --- | --- | --- | --- |
| NOW Sports Pumpkin Seed | 10 g per 15 g | About 38 g | About 125 |
| Probase Nutrition | 19 g per 30 g | About 40 g | About 130 |
| Sprout Living (unflavored) | 20 g per 32.5 g | About 41 g | About 190 |
| Micro Ingredients | 18 g per 30 g | About 42 g | About 165 |
| Sprout Living (vanilla) | 20 g per 36 g | About 45 g | About 210 |
| Truvani blend (chocolate) | 20 g per 33 g | About 41 g | About 165 |

Calories vary more than protein does. The gap comes mostly from fat. Sprout Living lists 5 g of fat per serving, which is real pumpkin seed oil left in the powder, while NOW and Probase list 0 g. If you are using protein powder to cut calories, that difference adds up to about 60 calories per 25 g of protein. If you are using it in smoothies or oats, the extra fat is not a problem, and some of it is the omega-6 and other fats that pumpkin seeds are known for.

The practical upshot is simple. Do not compare pumpkin seed scoops with whey scoops. Decide how much protein you want from the shake, which our guide to [how much protein you need](https://www.best-proteinpowder.com/how-much-protein-do-i-need/) can help with, then weigh or measure the powder to hit it. For most people that means two scoops of Sprout Living or Micro Ingredients, or three of NOW's small tablespoons, to land near 25 g.

## 3. The Best Pumpkin Seed Protein Powders, Ranked

We ranked these on protein per gram of powder, ingredient simplicity, minerals, the testing each brand documents, how widely they are sold and approximate cost per 25 g of protein. Five are pumpkin-only powders; one is a pea-led blend that includes pumpkin seed. Label figures are per the label or retailer listing at the time of writing and vary by flavor and batch. We did not taste-test these; taste and mixing notes come from buyer feedback.

[Check price on Amazon](https://www.amazon.com/dp/B0F3LSV14D?tag=sktiger-20&linkCode=ll1)

### 6. Truvani Organic Plant Based Protein Powder

**Award:** Best Pumpkin Seed Blend | **Type:** Organic pea, pumpkin seed and chia blend

- **Protein per serving:** 20 g per 33 g (label, chocolate)
- **Calories:** About 130
- **Third-party testing:** USDA Organic; brand shows one lot's lead test
- **Best for:** Balanced amino acids

Truvani is not a pumpkin-only powder. Pea protein leads, with organic pumpkin seed and chia seed protein behind it, which is exactly the pairing that fixes pumpkin seed's low lysine. Per the label at the time of writing, the chocolate flavor gives 20 g of protein in a 33 g scoop with 130 calories and 2 g of fiber, sweetened only with monk fruit. It is USDA Organic and comes in many flavors. Truvani shows lead results for one lot of its chocolate protein on its website.

**Bottom line:** Choose it if you want pumpkin seed in your shake but care more about complete protein and taste than a single-seed label.

**Pros:**

- Pea plus pumpkin seed gives a more balanced amino acid profile
- Short organic ingredient list, sweetened only with monk fruit
- Many flavors, including an unflavored version

**Cons:**

- Pumpkin seed is a minor ingredient, not the main protein
- Contains pea, so it does not suit people avoiding legumes
- Among the priciest per 25 g here, at about $50 for 20 servings

## 4. Amino Acids: Lysine Is the Weak Spot, Leucine Is Fine

Pumpkin seed protein contains all nine essential amino acids, so brands are not wrong to call it complete. But completeness is about proportions, not presence. Published analyses of pumpkin seed protein generally find lysine is its lowest essential amino acid relative to human requirements, which makes lysine the limiting amino acid, the one that caps how much of the protein your body can use for building new tissue. It is rich in arginine and glutamic acid, which are not limiting for most people.

This is the mirror image of pea protein. Pea is rich in lysine and low in the sulfur amino acids, methionine and cysteine. Seeds and grains tend to be the reverse. That is why so many plant blends pair pea with a seed or grain, and why Truvani and OWYN both combine pea and pumpkin. If you use a single-ingredient pumpkin powder every day, eating lysine-rich foods elsewhere, such as beans, lentils, tofu, dairy or eggs, closes the gap without any effort.

Leucine is the amino acid most closely tied to switching on muscle protein synthesis after a meal, and a figure of roughly 2 to 3 g per meal is often cited as the useful threshold. None of the pumpkin seed brands here print a full amino acid profile on the panels we saw, so we cannot give exact leucine numbers. Plant proteins generally carry less leucine per gram than whey, which is why a slightly larger plant serving, about 25 to 30 g of protein, is the usual advice for muscle goals.

For most buyers, none of this rules pumpkin seed out. If total daily protein is adequate and your diet includes some legumes, soy or animal foods, the lysine shortfall in one shake is unlikely to matter. It matters more if pumpkin seed is your only protein source, if you are older and trying to preserve muscle, or if you eat a narrow vegan diet. In those cases a pea and pumpkin blend, or rotating pumpkin with pea protein, is the better choice.

> **THE RULE**
>
> **Pumpkin seed needs a lysine partner**
>
> Pumpkin seed protein is low in lysine; pea protein is high in it. Use a pea and pumpkin blend, alternate the two, or make sure legumes, soy, dairy or eggs show up elsewhere in your day.

## 5. Fiber, Iron, Magnesium and Zinc

Minerals are pumpkin seed protein's best argument. Per the labels at the time of writing, Sprout Living's unflavored serving lists 4 mg of iron, 250 mg of magnesium and 2.5 mg of zinc, roughly 22, 60 and 23 percent of the daily values. Micro Ingredients lists 8 mg of iron per serving, about 44 percent of the daily value. Probase lists 6.88 mg of iron with magnesium at 90 percent and zinc at 50 percent of the daily value. NOW lists 3.4 mg of iron and 177 mg of magnesium in its smaller 15 g serving.

Those are meaningful numbers for vegans and vegetarians, who often fall short on zinc and iron. Plant iron is non-heme iron, which is absorbed less efficiently than iron from meat, and seeds also contain phytate, which binds minerals. So the label figure overstates what you absorb. Pairing the shake with vitamin C, from berries, citrus or kiwi in a smoothie, helps non-heme iron absorption, and avoiding tea or coffee at the same time helps too.

Fiber is modest compared with hemp. Pumpkin seed powders list about 1 to 4 g per serving, against 6 to 9 g for a typical hemp powder. That makes pumpkin easier on the stomach for people who find hemp heavy, and it means a pumpkin shake will not do much for a daily fiber target on its own. If fiber is a goal, our batch guide to the [best protein powder with fiber](https://www.best-proteinpowder.com/best-protein-powder-with-fiber/) covers powders that add it on purpose.

One caution on minerals: more is not automatically better. If you already take a multivitamin or an iron supplement, or you eat a lot of fortified foods, adding two or three servings of a high-iron powder a day can push iron intake well above what you need. People with hemochromatosis, kidney disease or on prescribed mineral supplements should check with a doctor or registered dietitian before adding a mineral-rich powder. This is not medical advice.

## 6. Who It Is For: The Allergen-Friendly Case

The strongest reason to choose single-ingredient pumpkin seed protein is what it leaves out. It contains no dairy, soy, egg, wheat, peanut or pea. That matters more than it sounds, because pea has become the default base of plant protein, and a growing number of people react to it, avoid legumes for digestive reasons, or follow elimination diets that remove them. Pumpkin seed is one of the few plant proteins that is not a legume, a grain or a common allergen.

That also makes it one of the few plant powders that fit a strict paleo or Whole30 approach. Sprout Living is Whole30 Approved per its listing. Our [paleo protein powder](https://www.best-proteinpowder.com/best-paleo-protein-powder/) guide focuses on animal sources, but it notes that seed proteins such as pumpkin and hemp are the plant exceptions. For low-FODMAP diets, Sprout Living describes its pumpkin protein as low-FODMAP, which is a brand claim rather than a certification we could confirm.

Read the facility statements, though. A single-ingredient label is not the same as an allergen-free facility. Sprout Living says its powders are made in a facility that may process dairy, soy, wheat, tree nuts and peanuts. Probase lists a facility that also handles peanuts, tree nuts, soy, wheat, milk, coconut and egg. If you have a severe allergy rather than a preference, contact the brand about cross-contact controls before buying, and talk to your allergist.

Pumpkin seed protein also suits vegetarians and vegans who want variety. Many plant eaters end up relying on the same pea blend every day; rotating in pumpkin, hemp or rice spreads exposure across sources, which also spreads any contaminant risk. Our batch guide to the [best protein powder for vegetarians](https://www.best-proteinpowder.com/best-protein-powder-for-vegetarians/) covers the wider field, including egg and dairy options that vegans skip.

## 7. Taste, Color and Texture: Expect a Green Shake

Pumpkin seed protein is green. Depending on the batch, it ranges from olive to a fairly bright moss green, because hulled pumpkin seeds are green themselves. Mixed with water, it makes a green drink; mixed with chocolate or berries, the color fades into brown or purple. It is worth knowing in advance, because buyers who expect a beige powder like pea or whey are sometimes put off by the first scoop.

Buyer feedback on the unflavored powders usually describes the taste as nutty and earthy, closer to toasted seeds than to the bitter, beany note that some people notice in pea protein. Most buyers do not recommend drinking it in plain water. Texture reports vary by brand: some describe a fine, smooth powder, others a slightly gritty or sandy mouthfeel, especially in a shaker bottle rather than a blender.

The best way to use the plain powders is in food. Pumpkin protein works well in smoothies with banana, cacao or peanut butter, in oatmeal and overnight oats, and in baked goods such as muffins and energy bites, where its nutty flavor fits. Our [smoothie protein guide](https://www.best-proteinpowder.com/best-protein-powder-for-smoothies/) and [baking protein guide](https://www.best-proteinpowder.com/best-protein-powder-for-baking/) cover how plant powders behave in each. Because it contains some fat and little starch, it does not dry out baked goods quite as much as a pure isolate.

If you want a drink you can shake with water, Sprout Living's vanilla version, sweetened with banana and stevia, is the only pumpkin-only flavored powder we found from a major specialty brand. Blends such as Truvani mask pumpkin's flavor with pea, cocoa and monk fruit and come in a long list of flavors. Neither will taste like a dessert-style whey, but both are much easier to drink than the plain powders.

## 8. Heavy Metals and Testing

Like every plant protein, pumpkin seed protein can carry trace heavy metals, mainly lead and cadmium, taken up from soil. Concentrating a seed into a protein powder can concentrate those metals too. Consumer Reports' October 2025 protein investigation found that plant-based powders tended to have more lead than dairy-based ones, and seeds, rice and cocoa are all common sources. This does not make pumpkin protein unsafe, but it is the main reason testing matters in this category.

Most pumpkin seed brands say little about their results. Sprout Living says its ingredients and finished goods are third-party tested in the USA. Micro Ingredients says its powder is third-party lab tested. Neither publishes numbers on the product pages we saw. Truvani shows lead results for one lot of its chocolate plant protein on its website, but not a full batch record. None of the pumpkin powders here carry NSF Certified for Sport or Informed Choice certification that we could confirm.

The Micro Ingredients listing carries a California Proposition 65 warning for lead. That warning is common on plant and mineral-rich foods because the Prop 65 threshold for lead is extremely low, well below many federal guidelines, and some brands label conservatively to avoid legal risk. A warning tells you lead is present at or above that threshold; it does not tell you how much. Brands without the warning may have lower results or may simply not sell into California.

The sensible approach is the same as with rice and hemp. Prefer brands that will share a certificate of analysis on request, avoid making a single seed powder your only protein at three servings a day, and rotate between sources. Our guide to the [best protein powder without heavy metals](https://www.best-proteinpowder.com/best-protein-powder-without-heavy-metals/) covers which powders publish results and how to read them. Pregnant or breastfeeding readers should talk to a doctor about any protein supplement.

## 9. Cost per 25 g of Protein

Pumpkin seed protein is expensive compared with whey or pea, because it is a smaller, organic-only niche and the seeds are pricier to process. The table below shows approximate cost per 25 g of protein using the label protein per serving and the prices we saw at retailers or brand sites at the time of writing. Prices change often and vary by size, so treat these as a guide to relative value rather than a quote.

| Powder | Price seen (size) | Total protein | Approx. cost per 25 g |
| --- | --- | --- | --- |
| Micro Ingredients | $29.99 (2 lb, 30 servings) | About 540 g | About $1.40 |
| NOW Sports Pumpkin Seed | $26.68 (1 lb, about 30 servings) | About 300 g | About $2.20 |
| Sprout Living, unflavored | $59.95 (2 lb, 30 servings, brand site) | About 600 g | About $2.50 |
| Probase Nutrition | $32.99 (1 lb, 15 servings) | About 285 g | About $2.90 |
| Truvani blend | About $50 (20 servings) | About 400 g | About $3.10 |
| Sprout Living, vanilla | $34.20 (1 lb, about 13 servings) | About 260 g | About $3.30 |

Micro Ingredients wins on price by a clear margin, largely because it sells a 2 lb bag at a price close to other brands' 1 lb jars. NOW is the value pick among smaller sizes and also wins on calories. Sprout Living's 1 lb bag works out to about $2.80 per 25 g at the $31.30 price we saw, so moving up to the 2 lb or 5 lb size saves real money if you know you like it.

For context, a typical pea isolate often lands well under $1.50 per 25 g, and many hemp powders sit between about $1.50 and $3. Pumpkin seed is a premium choice. It makes the most sense when its specific strengths, the allergen profile, the minerals or the single-ingredient label, are the reason you are buying it. If all you need is cheap plant protein, pea is the better buy, and our [pea protein guide](https://www.best-proteinpowder.com/best-pea-protein-powder/) ranks the options.

## 10. How to Use Pumpkin Seed Protein

Use it by grams of protein, not scoops. Decide how much protein you want from the shake or meal, then measure the powder. About 38 to 45 g of most pumpkin powders gives 25 g of protein. A kitchen scale makes this easy the first few times, and after that you will know roughly how many scoops it takes.

Blend rather than shake. Pumpkin seed protein mixes better in a blender with fruit, nut butter or oats than in a shaker bottle with water. If you do use a shaker, add the liquid first, then the powder, and let it sit for a minute before shaking. Plant milks such as oat or soy improve the texture, and soy milk adds lysine, which helps the amino acid balance.

Pair it with a lysine source, or mix it with pea. A simple half-and-half mix of pumpkin and unflavored pea protein gives you a more balanced amino acid profile and brings the cost per 25 g down. If you want greens in the same scoop, our batch guide to the [best greens protein powder](https://www.best-proteinpowder.com/best-greens-protein-powder/) covers blends that already combine plant protein with vegetables, some of which include pumpkin seed.

Store it cool and closed. Pumpkin seed protein contains some residual oil, especially the higher-fat powders, so it can go stale faster than an isolate once opened. Keep the bag sealed, away from heat and light, and use it within a few months of opening. If it smells sharp or paint-like, the fat has gone rancid and it is time to replace it.

## 11. Common Mistakes to Avoid

### Comparing scoops instead of grams of protein

NOW lists 10 g of protein per serving and Sprout Living lists 20 g, but NOW's serving is less than half the size. Per gram of powder, NOW is actually more concentrated. Always compare protein per gram, or the powder needed for 25 g, before deciding that one pumpkin powder is weaker than another.

### Making pumpkin seed your only protein

Pumpkin seed protein is low in lysine, so relying on it alone for most of your daily protein is not ideal. Pair it with legumes, soy, dairy or eggs elsewhere in your day, or use a pea and pumpkin blend, so the amino acid profile balances out across meals.

### Ignoring the facility allergen statement

A one-ingredient label does not mean an allergen-free facility. Several pumpkin seed brands are packed alongside dairy, soy, wheat, peanuts or tree nuts. If you have a true allergy rather than a preference, ask the brand about cross-contact controls before buying and follow your allergist's advice.

### Expecting it to taste like whey

Unflavored pumpkin seed protein is green, earthy and nutty. In plain water most buyers find it hard to enjoy. Plan to use it in smoothies, oats or baking, or buy a flavored version such as Sprout Living vanilla, rather than giving up after one unpleasant shaker bottle.

### Taking three servings a day of one seed powder

Plant proteins can carry trace lead and cadmium, and few pumpkin brands publish their numbers. Using one seed powder heavily every day concentrates any exposure. Rotate between pumpkin, pea and other proteins, and ask brands for a certificate of analysis if you rely on one powder.

## 12. Frequently Asked Questions

### Is pumpkin seed protein a complete protein?

It contains all nine essential amino acids, so it is technically complete. But lysine is low relative to human needs, which makes it the limiting amino acid. That is fine if you eat legumes, soy, dairy or eggs elsewhere. If pumpkin seed is your main protein, a pea and pumpkin blend gives a more balanced profile.

### How much protein is in pumpkin seed protein powder?

Per the labels at the time of writing, the powders here give 10 to 20 g of protein per serving, but serving sizes run from 15 g to 36 g. By weight, they are about 55 to 67 percent protein. Expect to use roughly 38 to 45 g of powder for 25 g of protein, compared with about 30 g for pea isolate.

### Is pumpkin seed protein better than pea protein?

Not overall. Pea protein is cheaper, denser and richer in lysine. Pumpkin seed wins on minerals such as magnesium, iron and zinc, and on allergen profile, since it is not a legume. Many people do best with both, either in a blend or by alternating, which also balances their amino acids nicely.

### Why is my pumpkin seed protein green?

Hulled pumpkin seeds are naturally green, and pressing and milling them keeps that color. It is normal and not a sign of added greens or spoilage. In chocolate or berry smoothies the color mostly disappears. If the powder smells sharp or paint-like, though, its residual oil may have gone rancid and it should be replaced.

### Does pumpkin seed protein contain heavy metals?

Like all plant proteins, it can contain trace lead and cadmium from soil. Few brands publish results, and one listing here carries a Prop 65 lead warning, which reflects a very low threshold. Choose brands that share test results, rotate protein sources and avoid relying on one seed powder at several servings a day.

### Is pumpkin seed protein good for building muscle?

It can support muscle gain when total daily protein is adequate, but it is not the most efficient option. It is lower in leucine and lysine than whey. Aim for about 25 to 30 g of protein per shake, and combine it with pea or other lysine-rich foods. Training and total intake matter far more than the specific powder.

### Is pumpkin seed protein safe for everyone?

For most healthy adults, a serving or two a day is a reasonable food. People with seed allergies, kidney disease, iron overload conditions, pregnancy or regular medication should check with a doctor or registered dietitian first, especially because these powders are rich in minerals. This guide is general information and not medical advice.

## The Bottom Line

For most people who want pumpkin seed protein, Sprout Living's unflavored Simple Protein is the one to buy: one organic ingredient, 20 g of protein per serving and a strong mineral profile. Micro Ingredients is the budget choice at roughly $1.40 per 25 g, and NOW is the leanest and most concentrated if you measure by grams rather than servings.

Buy pumpkin seed for what it does well: an allergen-friendly, pea-free, mineral-rich plant protein. Pair it with lysine-rich foods or a pea protein, rotate sources to spread heavy-metal exposure, and if cheap protein per dollar is your only goal, pea will serve you better.
