KOS organic protein has some digestive enzymes as well. These enzymes include protease, lipase, lactase, amylase, and cellulase. Digestive enzymes help to digest the protein smoothly.

Let’s analyze one serving of KOS Organic Plant-Based Protein Powder.  (The macro breakdown of one serving)

One serving provides you:-

  • Calories = 170 kcal
  • Protein = 20 grams
  • Carbs = 9 grams (including 2 gram sugar)
  • Fat = 6 grams (including 3.5 grams of saturated fat)

The blend of vegetables like tomato, broccoli, carrot, shiitake mushroom, cranberry apple, and orange will provide them enough nutrients they need for proper growth and development.   

Though there was no mention of amino acid profile on the package, I am sure that the blend of quinoa, flax, pumpkin seed protein, chia seeds, pea protein should result in a complete amino acid profile with a good amount of omega 3 fatty acids.

Considering all these facts and trends, the supplement maker decided to donate 1% of their total sales for animal rights and the environment.
