### Love it!
This is the best chocolate shake. Taste is excellent, consistency is good and blends well and quickly in my shaker bottle. Also love the little "gifts" they add to my package every time.  
Thanks, KOS!! 😊

### Low glycemic sugars
I like the taste and content of KOS plant protein including the small amount of added sugar from coconut palm sugar, monk fruit, and stevia.

### Not satisfied!
It is too thick for my liking. I have to keep adding water just to make it drinkable & then it is too diluted. It’s not a finely sifted powder.

### Nutritious and versatile
I love the vanilla KOS powder a lot. I have a vegan child who doesn’t love to eat protein so this powder saves me! I put it in pancakes, muffins, smoothies, and cold oats. It adds sweetness without sugar and plenty of nutrition. I love it.  
Vanilla is my #1 favorite.

### What makes KOS different from other protein powders?
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.

### Is KOS protein a complete protein?
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.

### What's your return policy?
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.

### Is KOS safe during pregnancy?
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.
