Plant protein powders have come a long way from the gritty, grassy shakes of the past. Today the four most popular options are pea, brown rice, pumpkin seed, and hemp, and each has a different strength. This guide compares them on the things that actually matter: protein content, amino acids, digestibility, taste, texture, and what each is best for.

Understanding "complete" protein
Your body needs nine essential amino acids from food. Most plant proteins contain all nine but are relatively low in one, called the limiting amino acid:
• Pea protein is rich in lysine but lower in methionine.
• Rice protein is the reverse: lower in lysine, richer in methionine.
That's why pea and rice protein are so often blended. Together they cover each other's gaps, giving an amino acid profile much closer to animal proteins. Many commercial blends use more pea than rice.
Pea protein
Pea protein is extracted from yellow split peas. It's the most popular plant protein because it's high in protein, mixes smoothly, and is rich in the branched-chain amino acids (BCAAs) linked with muscle building. In a 12-week trial, pea protein produced gains in muscle thickness similar to whey in people doing resistance training.
Best for: everyday shakes, muscle building, and dairy-free foods.→ Read the full pea protein guide | Shop organic or conventional pea protein
Brown rice protein
Rice protein is extracted from brown rice, often using enzymes. It's hypoallergenic, mild-tasting, and in one well-known study it supported body composition changes similar to whey during resistance training. Its main role in many formulas is complementing pea protein. Our organic rice protein is an 80% protein concentrate made from organic brown rice using an enzyme-based process.
Best for: blending with pea, sensitive stomachs, and allergen-friendly products.→ Read the brown rice protein guide
Pumpkin seed protein
Made from pumpkin seeds after the oil is pressed out, pumpkin seed protein is naturally green, nutty, and less processed than many isolates. That means it keeps more of the seed's minerals, such as magnesium, zinc, and iron. Its protein content is lower (around 60–70%), and it's a great fit for baking and savory recipes.
Best for: whole-food nutrition, baking, energy bars, and savory dishes.→ Read the pumpkin seed protein guide | Shop pumpkin seed protein or 70% grade
Hemp protein
Hemp protein is milled from hemp seeds after pressing. It's the least refined of the four: lower in protein per scoop, but it brings fiber and healthy fats. Its texture is coarser and its flavor earthier.
Best for: fiber-rich smoothies and whole-food nutrition.→ Shop organic hemp protein
How much protein do you actually need?
• General adults: the RDA is 0.8 g per kg of body weight per day, a minimum to prevent deficiency.
• Active people and those building muscle: sports nutrition guidance commonly suggests about 1.4–2.0 g per kg per day, spread across meals.
• Per serving: about 20–40 g of protein per meal or shake is a common target for muscle building. Because plant proteins tend to be slightly lower in leucine than whey, aim toward the upper end of that range, or use a blend.
Which plant protein should you choose?
• Maximum protein per scoop and smooth shakes: pea, or a pea and rice blend.
• Most complete amino acid profile: pea and rice combined.
• Least processed, most minerals: pumpkin seed or hemp.
• Sensitive digestion or allergies: rice protein is often the gentlest. Pea is also well tolerated by most people.
• Baking and savory cooking: pumpkin seed.
• Pairing with creatine: any of them. See creatine for vegans and vegetarians.
What to look for in a plant protein powder
1. Protein percentage on a spec sheet or label.
2. Ingredient list: unflavored single-ingredient powders give you full control.
3. Organic certification, if important to you.
4. Third-party testing for heavy metals: this matters for all plant proteins and especially rice. Reputable suppliers can provide a certificate of analysis.
5. Allergen and facility information.
For food and supplement manufacturers
Plant proteins differ in solubility, gelation, emulsification, and flavor, which affects how they behave in beverages, bars, and meat alternatives. See how businesses can choose the right plant protein ingredients, or browse our protein collection and request bulk pricing.
FAQ
Which plant protein is closest to whey?Pea protein, especially blended with rice protein, is the closest in amino acid profile and has performed similarly to whey in muscle-building studies.
Is pea or rice protein better?Pea is higher in lysine and BCAAs. Rice is gentler and higher in methionine. Together they're better than either alone.
Is hemp protein a complete protein?It contains all nine essential amino acids but is relatively low in lysine. It's best combined with other proteins in a varied diet.
Can I use plant protein for baking?Yes. Pumpkin seed and pea proteins bake well. Replace a portion of the flour and add a little extra liquid.
