The Science

Why Pea Protein Wins

Complete essential amino acids

Complete essential amino acids

Pea protein contains all nine essential amino acids your body cannot make on its own, including high levels of branched-chain amino acids and leucine, the key trigger for muscle protein synthesis.

All 9 Essential Aminos

Complete protein profile from a single plant source, not a blend of compromises

High in BCAAs

Rich in leucine, isoleucine, and valine for muscle protein synthesis

High Leucine Content

The primary trigger for muscle protein synthesis at levels comparable to whey

No Blending Required

A single-source complete protein with no need to combine multiple plant sources

Clinical Nutrition

Protein That Works in Real Life

Nutrition science only matters if it fits your life. PURIS pea protein works in the meals and routines you already have.

Strength

Lean Muscle

A leucine-rich amino acid profile drives muscle protein synthesis, supporting both growth and long-term maintenance whether you train daily or just stay active.

All day fuel

Steady Energy

Protein slows digestion and moderates glycemic response, helping you avoid the spikes and crashes that come with carb-heavy meals. Consistent fuel from morning to night.

Gut friendly

Easy Digestion

PURIS pea protein isolate scores 82% on the PDCAAS digestibility scale - higher than rice, oat, or chickpea - and is free from lactose and all top allergens, so it sits easy even at higher daily intakes.

Post-workout

Daily Recovery

Essential amino acids, including arginine at three times the level found in whey, support tissue repair after exercise and help your body bounce back from the demands of everyday life.

Pea Protein FAQ

What exactly is pea protein made from?

Pea protein is made from field peas (Pisum sativum), the kind you would use to make split pea soup. This is the same species but a different varietal than garden, sweet, or English peas. Both contain about 20-23% protein, and field peas are lower in sugar. PURIS sources from dedicated growers in Montana, North Dakota, South Dakota, and Nebraska.

PURIS Pea Protein contains all nine essential amino acids, making it a valuable source of plant-based protein. It is rich in branched-chain amino acids including leucine, the key trigger for muscle protein synthesis. Research shows that muscle outcomes with pea protein are comparable to whey when daily protein targets are met.

Whey is a dairy byproduct with higher sugar and calorie content. PURIS pea protein offers all 20 amino acids, is high in BCAAs, and delivers three times the arginine of whey, which supports blood flow and muscle protein synthesis. Unlike whey, pea protein is free from all top 9 allergens and suitable for vegan, dairy-free, and allergen-sensitive diets.
