What is Pea Protein?

Pea protein is a plant-based protein isolate derived from yellow peas (Pisum sativum). It is produced by drying and milling peas before processing them to remove the fiber and starch, leaving behind a protein-rich powder.

It is used as a protein supplement in various food and beverage products, often as an alternative to animal-based proteins like whey. Health studies suggest that pea protein is a good source of essential amino acids and is hypoallergenic, making it suitable for people with dairy or egg allergies. It also supports muscle growth and repair.

When you see pea protein on a label, it's often in products targeting vegans or those looking to increase protein intake without animal products. It is generally well-tolerated and considered a good addition to plant-based diets.

Commonly found in: protein shakes, meal replacement bars, snacks, baked goods, dairy alternatives

Benefits

  • Contains all nine essential amino acids.
  • Hypoallergenic, suitable for those with common food allergies.
  • Supports muscle growth and repair in a manner comparable to milk proteins.
FDA

Pea protein is considered GRAS (Generally Recognized as Safe) by the FDA for its intended uses in food products.

Research

Research supports pea protein's effectiveness in supporting muscle synthesis and overall health, though studies note it may have a slightly lower bioavailability than animal-based proteins.

Vegan

Pea protein is plant-derived and well-regarded by the vegan community as a strong and ethical source of protein.

More from Scout's analyses

Plant-based protein that's notably good for a legume but still less bioavailable than whey or other animal-source proteins, meaning more grams are needed to deliver the same usable amino acids for muscle protein synthesis. Naturally low in methionine, so it does not stand alone as a complete protein and is typically blended with rice. Pea crops are also well-documented soil accumulators of lead and cadmium — the suspected primary contamination route in this product.
