KOS is designed around real use. We use organic, plant-based ingredients chosen for taste, digestibility, and nutritional quality, without artificial sweeteners, fillers, or unnecessary additives.
The result is protein powder people actually enjoy drinking and can stick with daily.

KOS is formulated using complementary plant proteins - including pea, pumpkin seed, quinoa, chia, and flax - that work together to provide all nine essential amino acids the body can’t produce on its own.
While individual plant sources may not be complete on their own, combining them at the right ratios allows KOS protein to deliver a complete amino acid profile per serving.
