Supplement companies are trying to make you buy supplements you don’t need

There are hundreds of supplements available for purchase, and Examine has analyzed over 400 of them.

With the overwhelming number of supplements you could buy, how do you figure out which ones you need?

It’s not like you can trust supplement companies; they have one goal: to convince you to buy their supplements.

Are you getting the supplements you actually need?

Instead of relying on marketing claims, you need to figure out which supplements are worth your time and which are a waste of money.

Here’s the truth: you should take specific supplements based on your health goals. A 60-year-old with aching joints has different needs than a 30-year-old who can’t fall asleep; recommending the same supplements to them is wasteful and senseless!

Making sense of the information — and misinformation — out there can be overwhelming. There’s a ton of conflicting information online, and most of it is pushed by people trying to sell you specific supplement brands. Plus, reading scientific research is a complex skill that requires specific education and expertise.

This is where we can help.

We do not sell any supplements

Examine’s only goal is to break down and make sense of research. Not only do we not sell supplements, but we also don’t recommend any brands, nor do we do any consulting or accept advertisements, donations, or sponsorships.

We are 100% independent and extremely serious about being unbiased when it comes to nutrition and supplement information.

We only care about the science. It’s why millions of people visit us every month, why professionals from major sports leagues rely on us for nutrition and supplement analysis, and why we have tens of thousands of customers.

To that end, we created the Supplement Guides to help you level up your knowledge and take only the supplements that are proven to work — and skip the ones that waste your time and money.

Here are the topics our 17 guides cover:

The Supplement Guides

Go from “This supplement works... I think?” to “I know these supplements work.”

Achieve your health goals

There is no magic pill that works for everyone; instead, you need to take the supplements that help achieve your goal.

So we created 17 different guides, each focused on helping you optimize a specific health goal.

We analyzed all of the available scientific research so we can give you the best recommendations on how to optimize your health.

Actionable steps, with a focus on what actually works — and what doesn’t

We have four main goals when recommending a supplement. We tell you:

  1. Why you should take it.
  2. When you should take it.
  3. How much you should take.
  4. If the supplement combines well with any other supplement.

We use our decades of knowledge and research to give you easy-to-understand, step-by-step directions to help you optimize your supplementation.

Take the ideal combination of supplements — for you

Some supplements can impact the efficacy and potency of other supplements. Bolster your results by learning how best to combine supplements based on your situation and goals.

Not everyone is the same — we each have our own health issues, concerns, and goals. We understand that, so our guides give you the context and information behind supplements so you know exactly which ones are worth your time and money, and which you can safely skip.

Save time and money

The average American spends over $350 on supplements every year!

People take supplements they think are helping but are not useful; our guides help you identify which supplements you don’t need.

The guides will pay for themselves with the savings they’ll bring you in the long run.

Unbiased information you can trust

Our guides only tell you what to take, not which brand, because we are 100% fiercely independent. You won’t be hit with the unfounded claims and outright misrepresentation of research that are the tactics of shady supplement companies.

You can supplement confidently, knowing our recommendations are based on science and not because we’re trying to push profits.

A clear prioritization of supplements

The reality is that science is not exact. Sometimes there’s evidence that a supplement may work, but we cannot be 100% sure.

So we’ve broken down our recommendations into five descending sets of priorities:

  1. Core supplements have the best safety-efficacy profile.
  2. Primary options can be effective in the right context.
  3. Secondary options may be worth adding, but the evidence is limited.
  4. Promising supplements are backed only by preliminary evidence.
  5. Inadvisable supplements are likely to harm your health and/or wallet.

This way you can maximize your hard-earned money and spend it on what you wish rather than wasting it on supplements that will be useless to you

Free lifetime updates keep the guides reliable and up to date

With free lifetime updates, even as your needs change, our guides remain useful.

There are hundreds of nutrition studies published each month. It’s why we have an entire research team whose only job is to stay abreast of the latest research. If you take a look at our social media, you’ll see we’re always posting about research as it is published.

Here is an example of one section from one of our guides being expanded over the years:

What is Examine and why should you trust us?

  • Examine 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 ineffective), it has no impact on our bottom line. Consider us the Switzerland of the world of nutrition and supplementation.
  • Since our inception in early 2011, we’ve had but one goal: to be the best source of unbiased information on supplements and nutrition. MDs, biophysicists, pharmacists, dietitians, sports nutritionists, kinesiologists … the members of our team are all accredited experts, but with very different backgrounds, so that when we do research, we get the full picture. That’s why we have over 50,000 references on our website — we’re happy to show our work.
  • This single-minded dedication to providing well-researched, unbiased information has made us the #1 site for supplement information. Over 2.5 million people visit us every month. We have over 65,000 happy customers. And when major media organizations — the BBC, the New York Times, the Washington Post, Men’s Health, and many more — need experts, they turn to us.

The professionals rely on Examine’s evidence-based analyses.

For John Berardi and his team, Examine is a trusted resource

Whenever I want unbiased, meticulously researched, and scientifically credible supplement information, I turn to my friends at Examine. They review thousands of studies and give bottom-line supplement recommendations better than anyone else in the industry. For me, my team, and my colleagues, they’ve become a trusted resource.

Jennifer Sygo uses Examine to get “the lay of the land” quickly

John Meadows trusts Examine to tell him the truth on supplements

I’ll keep this simple: Examine is where I go when I want to look up what the science says on supplements and nutrition.

Mike Hart visits Examine daily

Examine is the most trusted resource on the internet for making intelligent decisions regarding your health. I visit it daily and frequently suggest to my patients to visit Examine before purchasing any supplements or making any dietary changes.

Mike Hart, MD

For Dr. Bryan Chung, Examine is the repository resource for nutritional supplement information

Examine 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. Examine 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 Examine.

Dr. Yoni Freedhoff sees in Examine a massive and helpful undertaking

It’s insufficient to simply rely on belief, conjecture or internet advice to determine if supplements are right for you. Instead you need to rely on research. With Examine’s reference guide, not only will you find their summary of the research, but also links to the original papers should you want to do your own due diligence. Truly a massive and helpful undertaking.

Dr. Yoni Freedhoff, MD, CCFP, Dip, ABBM

All of our guides are written by researchers with no conflicts of interest

Frequently Asked Questions

Most supplement research comes with an inherent bias. Studies are often backed by supplement companies with a vested interest to arrive at a conclusion substantiating their claims. All of this is done with one purpose in mind - to make you spend your money on pills and powders which may not work.

Other companies that don't do research themselves just cherry pick studies that make their products look good. Often time these are studies performed on rats and in petri-dishes - not in actual humans!

As Examine is an independent company that does not sell any supplements, we do not cherrypick. We are not trying to sell you supplements. We are 100% neutral and conduct all of our research independently, allowing us to come to our own conclusions regarding the validity of which supplements work.

Absolutely. The Supplement Guides are actually written with our own mothers in mind. They are easy-to-read and give you simple step-by-step directions on which supplements to take (and which to not waste money on).

Supplement Guides are easy-to-follow with step-by-step instructions. They can be easily used by your mother or father! The Examine Membership helps you understand what the latest research is. It's great for those who want to take care of their health and keep up with scientific research.
