Everything you need to know about whey protein

To build or preserve muscle, no supplement is more popular than whey protein, and it’s one of the very few products also shown to promote fat loss.

Unsurprisingly, over the years, we’ve received hundreds of questions about whey. We’ve already answered several in our multiple articles on protein in general and whey protein in particular. Now, we’ve answered them all in the Definitive Guide to Whey Protein.

  • Compare whey to other sources of protein. Compare whey concentrate, isolate, and hydrolysate. Learn if you can benefit from blending proteins, or from taking specific ones at different times. Dose and time your protein intake to fit your health goals.
  • Find how sourcing and processing affect the protein … and your health. Discover the pros and cons of the different ingredients commonly added to protein powders. Understand the legal tricks supplement companies use to fool you.
  • Rely on expert, unbiased information. Examine.com is an education company. We don’t sell supplements or work with supplement companies; we don’t even accept ads. All we do all day, every day, is examining the scientific evidence.
