To be considered a great whey protein the product MUST list whey protein isolate or hydrolyzed whey protein isolate as the very first ingredient. But to really know if a whey protein powder is top notch, youll need to do some math. Take the grams of protein per serving listed on the supplement facts panel and divide it by the serving size (in grams). This will give you the percentage of protein in each serving. To be considered a great whey protein powder, the percent protein per serving (or scoop) should be 80% or greater. For example, if a whey protein powder provides 25 grams of protein per 28-gram scoop, that protein powder is about 90% protein and is a great whey protein for the money.ADVERTISEMENT
