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.
You choose how often you want deliveries: every 30, 60, or 90 days, and save 20% on every order. You can pause, skip, swap products, or cancel anytime in just a few clicks.
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.
If you don't love it, we'll refund it. Simple as that. Reach out within 15 days of purchase and we'll make it right - no need to ship anything back.
Our products are made with clean, organic ingredients, but we always recommend checking with your healthcare provider before adding any supplement to your routine during pregnancy or nursing.
