The healthiest pb powder is going to be an organic powdered peanut butter that has no added sugar. I like PB Fit organic pure peanut butter powder the best. PB Fit has a lot of different peanut powders, so make sure to buy the organic, no sugar added variety. When you're comparing that to PB2, PB Fit is healthier since it's higher in protein and lower in sugar than PB2's peanut powder options.
