"I’ve seen many forumites recommend Power Butter to other T-Nation readers. Power Butter is peanut butter made with flax seeds, flax oil and egg whites. It claims to be a high protein super food. It better be given that it sells for over $15 a jar!
Well, Labelclaimstesting.com and Research Triangle Park Laboratories tested it and here’s what they found:
Claimed protein per serving: 32 grams
Actual protein per serving: 17 grams
The fat claims were off too.
So much for that product! I never really understood it anyway. I like natural peanut butter, I like flax seeds, and I like egg whites, but do I really want to pay over 15 bucks for all three mixed together? Nope."
