Why it matters
Why protein matters
Protein is what your body uses to build and keep muscle, and muscle is one of the biggest drivers of healthy aging and a healthy metabolism.
Fuller for longer
Pea protein naturally supports the hormones that tell you that you are full.*
Complete, from plants
Pea, pumpkin seed and chia together cover every essential amino acid, with no soy, dairy or gluten.
Bonus fiber
4g of whole-food fiber from apple and broccoli in every serving.

Pea protein supports CCK and GLP-1, the hormones involved in feeling full.*
Read the full research summary
The three-source protein blend draws from pea, pumpkin seed, and chia to produce a complete amino acid profile. Pea protein provides arginine, supporting nitric oxide production and nutrient delivery, and glutamine, which supports gut lining integrity and muscle recovery. Pumpkin seed fills BCAA gaps. Chia contributes essential amino acids and omega fatty acids.
The 20g serving reflects research identifying this dose as the threshold for maximizing muscle protein synthesis in rested and exercised muscle. Lean muscle mass is a key determinant of metabolic rate, insulin sensitivity, and physical function, especially as we age.
Pea protein has been documented as a stimulator of CCK and GLP-1, satiety hormones involved in appetite regulation and metabolic balance. The 4g fiber blend from apple and broccoli powder provides additional gut health support.
