About Buyhi

https://buyhi.co

Buyhi quest for a better protein source began when they realized the harm that whey protein powder was causing to their bodies and the environment. The ingredient lists are lengthy, difficult to understand, and packed with hidden sugars, fillers, gum, artificial flavors, and gut irritants. They're all too sweet, make them feel bloated, and they make them tired. Buyhi discovered that the largest global contributor to environmental pollution is livestock protein as they began their research. This did not go over well with them, much like whey protein did. As a result, they decided to reimagine protein powder in order to develop a superior method of obtaining protein.
