Reap the Benefits

Complete Protein to Fuel Your Day

The KOS formulation is an infusion of essential nutrients and minerals—but not the kind cooked up in a lab. This is energy produced naturally through sun, air, water and soil. Yeah. Plant energy. The foundation of the planet’s food chain.

Control Cravings for Weight Management

You feel full, you stop eating. No rocket science there. The soluble fiber in plant protein gives you that “full” feeling for a longer period of time. You eat less but not at the expense of calories. Pardon our French, but Voila.

There is no point formulating a great protein blend if it tastes like cardboard. Sadly, many plant proteins do. We know. We tasted them all. We were disappointed but equally motivated. We believe KOS will be the best tasting plant protein you try.

The Freshest Source From Mother Nature


Organic Pea Protein

Peas contain those branched-chain amino acids that contribute to building muscle, burning fat, and repairing your exhausted clockwork after a strenuous workout.


Organic Flax Seed Protein

Flax seed is one of the richest vegan sources of essential omega-3. This fatty acid is critical to weight management, retinal health, and fetal development. Flax is also high in soluble and insoluble fiber, low in carbs, maintains blood sugar levels, and helps digestion.


Organic Milk Thistle Extract

Its antioxidant, anti-inflammatory, and hepatic properties are a healing trinity that keeps you in terrific working order.

Organic Inulin

Inulin naturally slows digestion - helping to prolong feelings of fullness - and may play a role in reducing blood sugar.


Organic Chia Seed Protein

These crazily tiny seeds contain omega-3 fatty acids, fiber, antioxidants, iron, and calcium to help you lean muscle mass and burn excess fat.


Organic Pumpkin Seed Protein

Packed with protein, heart-helping magnesium, immune-boosting zinc, and the natural sleep-aid tryptophan, pumpkin seed benefits your body and overall health.

VERIFIED BUYER

I am kind of obsessed with making smoothie bowls at home. It’s perfect for starting the day, as a mid day snack or even for dessert. I pack my bowls with healthy fruits and berries, plant based milk and I’ve been using @kos ‘s plant based protein.

This is the best protein powder ever! It tastes like brownie batter!!


I have tried nearly every kind of big brand protein powder and have never liked a single one. Either they are sickeningly sweet or have a terrible aftertaste- or both. This is the only protein powder that has such a delicious balanced taste, and I tend to not like sweet or flavored protein powders at all!

VERIFIED BUYER

Without any sliver of doubt, this is by far THE BEST ORGANIC VEGAN PLANT-BASED PROTEIN on the market! We were hook from the first drink. The natural ingredients, along with delicious taste, leaves you full of your daily nutrients throughout the day. Although not necessary due to the delicious taste, we also enjoy your daily KOS shake with a handful of spinach, avocado and peanut butter.
