What is fitness to you?


the Fitness Guide

In our Fitness Guide, you’ll find six of our top-selling Supplement Guides, plus added information on dieting efficiently and assessing your fitness level. You’ll learn which supplements work best, and more importantly, how to combine them to get the results you want.

Best of all, we make it easy-as-pie to figure out.

  • We begin each of the six primers with an overview of strategies to address common fitness-related problems.
  • We follow with a comprehensive list of the core supplements you should consider taking to reach your desired outcome.
  • Next, we move to primary options (which may provide substantial benefits in the right context), secondary options (which have less evidence for their effects), promising supplements (for which evidence is still mostly lacking), and inadvisable supplements (which are more likely to harm you or empty your wallet than support your efforts).
  • Finally, we look at different ways to combine your supplements so you reach your health and fitness goals, faster.

Who is

  • is an independent encyclopedia on supplementation and nutrition. We’re unique because we don’t sell supplements and aren’t affiliated in any way with any supplement company. When we recommend a supplement (or say another is garbage), it has no impact on our bottom line.

Our team comprises medical doctors, biophysicists, pharmacists, nutritionists, sports dietitians, kinesiologists, etc. — all accredited experts, but with very different backgrounds, so that when we do research, we get the full picture.

Eric Cressey trust's research-backed, unbiased perspective

The supplement industry can be tremendously confusing for a number of reasons. First, the margins are incredibly high — so there are a lot of unethical weasels with no scientific background making bold and unsubstantiated claims to separate you from your money. Second, it's a dynamic industry, as new products, brands, and research emerge every single day. Fortunately, the guys at have streamlined the process of educating us all by providing an incredibly up-to-date resource on the supplements we encounter on a daily basis, as well as some of the more obscure ones that are out there that might "stump" us. This is an excellent product not only because it's a completely research-backed, unbiased perspective without any financial conflicts of interest, but also because it's exhaustively thorough and well written. I highly recommend it.

For Dr. Bryan Chung, is the repository resource for nutritional supplement information has become THE repository resource for nutritional supplement information. Most other similar databases fail at what they're good at, which is being accessible and being comprehensive. Their frequent updates stay on top of the literature as it evolves. gives me an excellent overview of the body of work, which helps me filter and refine my search strategy when I'm looking up supplements that I get asked about that I've never heard of. The Human Effect Matrix provides interpretation that is lacking in every other supplement database in the world. Most people don't have the time or interest to develop high-level expertise, but need somewhere to turn to to make informed decisions about their supplements. That information is at
