what is whey powder made from?
<answer> Whey powder is made from buttermilk, skim. <context> Make Your Own Whey Powder! As always, I keep trying to lower my expenses...I started experimenting with homemade whey protein powder. The process just requires buttermilk, skim and (lots of) time. The outcome is many times cheaper then buying off the shelf protein, and I personally feel better knowing exactly what I am consuming.
