  • Complete Protein to
    Fuel Your Day
  • Immune Health
  • Blue Spirulina? Here's The Scoop
  • Finally a Great Tasting Plant Protein

Nature is pure power. Why? Because you can’t improve on the basics. Our USDA organic plant-based protein is delicious, additive-free, and a genuinely energy-packed addition to any lifestyle. 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.

This "whole foods combo in a capsule" works with the immune system to armor you up against micro-invaders—and to keep a close watch on your cellular health.

Phytonutrients help plants thrive while fighting off diseases that would do them harm. It would seem the natural mechanism wants animals that eat plants to partake of these same benefits. You might as well call them fighto-nutrients. Blue spirulina is packed with them.

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. Not satisfied? Not to worry, you have 60 days to send it back for a full refund. Isn't this easy?

Organic Pea Protein

Those peas you used to move endlessly around the dinner plate as a kid? They’re a complete source of protein. If only you’d known! Now, knowing all this likely wouldn’t have changed your mind about peas as a kid. But at least you would have understood what you were hiding under your potato.

Organic Flax Seed Protein

Unless you’re a fish, your body can’t make omega-3. No problem. Flax seed is one of the richest vegan sources of essential omega-3. This fatty acid with the science-fictional name is critical to weight management, retinal health, fetal development…omega-3 is a big deal, and Flax is an omega-3 kingpin.

Organic Quinoa Protein

Quinoa is nearly unique in the Plant Kindgom. Why? It is a “complete protein”, rare plant matter that contains all nine essential amino acids. Think of it as a cow you can toss into a salad. Packed with fiber, iron, magnesium, manganese—Quinoa is strangely potent. In fact, NASA is looking very closely at Quinoa as a Controlled Ecological Life Support System (CELSS); a foodstuff for astronauts on long interplanetary flights.

Organic Pumpkin Seed Protein

The seemingly unremarkable pumpkin seed is an incredibly useful thing for the body. Carotenoids and vitamin E round out the miracle.

Organic Chia Seed Protein

Chia seeds can be spread over the backs of terra cotta animals to look like green hair. But there’s more! These crazily tiny seeds are loaded with omega-3 fatty acids (those again), fiber, antioxidants, iron, and calcium. Drop them into water and chia seeds soak up about 12 times their volume in a scant 10 minutes, producing a nutrient-packed gel that can stand in for eggs in vegan cooking.

Organic Blue Spirulina

This cyanobacterium is one of Earth's earliest living things - and thus knows a thing or two about life energy. It's got micronutrients enough to charge your power cells for the long haul. They say the sea is the cradle of life. That would make spirulina its beautiful bouncing baby.

Organic Blueberry Powder

Unsurprisingly It tastes like tangy blueberries. What’s not to love?


Despite its name, this berry does not make you older. Quite the contrary.

Vitamin C From Acerola Cherry

This specific berry (not actually a cherry in the technical sense) has long been used as an antioxidant nutrient.

Turkey Tail Mushroom

The Turkey Tail mushroom, apart from its having the coloration of a Turkey Tail, is a known antioxidant and anti-inflammatory due to its phenols and flavenoid content.

Lion's Mane Mushroom

A billion years of life-pursuing evolution will do that.

Ginger Root

Ginger snaps, ginger ale, ginger root! Known for its diverse benefits, this is another kobby helpmate from beneath the soil.

Carrot Root

..or just "carrot", as it's commonly known. This familiar (and crazily orange) root is a natural antioxidant whose beta carotene converts to vitamin A in your grateful body. Vitamin A is good for your eyesight and your immune system.

Whole-Food Vitamins

A review of our container label will reveal that KOS Plant Protein contains vitamins from A to Z (zinc oxide) and all the minerals to be a complete mulitvitamin source. This is especially important when replacing meals and for Mom to know a KOS Protein shake provides a full spectrum of nutrients for active kids. Our vitamins and minerals are from whole food sources and Made in America without fillers, artificial ingredients, GMOs or additives.

Himalayan Pink Salt

The only salt known to have been discovered by none other than Alexander the Great, Himalayan salt is mined in the Punjab region of Pakistan. This far-flung table spice boasts a total of 84 minerals, including iron, magnesium, calcium, potassium, phosphorus and chloride, as well as trace amounts of body-burnishing boron, fluoride, iodine, zinc, selenium and copper. The best part of Himalayan salt? You don’t have to scale the Himalayas to get it.

DigeSEB™ Enzyme Blend

Amylase, Protease, Lipase, Lactase, Cellulase. Sound like a biology test? This proprietary enzyme blend helps the body embrace and capitalize on its ingested proteins, maximizing absorption and wasting less of the ingested component parts.
