    Fuel Your Day
  • Control Cravings for
    Weight Management
  • Responsibly Sourced & Artificial Ingredient-Free
  • 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.

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.

Our ingredients are as embraceable as a sunlit Saturday at your local farmer’s market, and organically produced by responsibly managed farms using sustainable practices. Nearly every ingredient is certified organic and therefore free of hormones, antibiotics, pesticides, artificial sweeteners, colors, and GMOs. Our products are made here in Southern California and ingredients are certified by the USDA and CCOF.

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 30 days to send it back for a full refund. Isn't this easy?

This is by far the best tasting protein I have ever had. It’s delicious!!

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—a key element of your cell membranes and their fancy little receptors.

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 Cacao

One of the richest sources of polyphenols and flavanols which have potent antioxidant effects. Studies show that Cacao can improve nitric oxide levels in the blood, which can enhance vascular health and reduce blood pressure.

Organic Coconut

Twice the iron and zinc of granulated sugar and rich in potassium, Coconut Sugar is produced from the sap of the coconut palm flower, and not from the plummeting nut known for knocking tourists unconscious. Coconut Sugar offers vitamin C, magnesium, calcium, and a variety of other nutrients. Plentiful in antioxidant phytonutients (naturally occurring plant-based anti-toxins) this tree-based sugar is a healthy alternative to processed sweeteners.

Organic Monk Fruit

Monk Fruit is a sweetener harvested from Southeast Asia. Remove the seeds and skin and crush the fruit, and the resulting extract is, like Stevia, about 200 times sweeter than sugar. Monk Fruit is native to China, and has been used there as a medicinal remedy for centuries. Monk Fruit is known to contain super-antioxidants called mogrosides.

Organic Stevia (Whole Leaf)

Derived from a South American plant of the same name, Stevia’s two main components are Stevioside and Rebaudioside A; and these are hundreds of times sweeter than table sugar. Stevia contains 0 calories and has a big fat 0 as its glycemic index, too.

Organic Inulin

A GI tract-friendly soluble fiber which plays a key role in feeding your trillions of gut flora, Inulin naturally slows digestion - helping to prolong feelings of fullness and dissuading you from your snacking predilection.

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.
