How the Supplement Guides improve your health

Level up your health with personalized supplement recommendations

“I have insomnia, arthritis, diabetes, and need to gain muscle. What will actually work for me?”

Tackle your specific health goals using one or all of our 17 tailored guides.

One size does not fit all for supplements — there’s no magic pill. Customize your supplement intake based on your goals/age/sex/weight/conditions using our guides.

Save time with easy to follow directions

Decades of research distilled into easy-to-understand, step-by-step directions you can use right now. With straightforward instructions, there’s no need to figure it all out on your own.

Save money with supplements backed by real science

Stop wasting money on dubious supplements based on Dr. TV’s daily sponsors, oversimplified news, or just plain flawed studies.

We are fiercely against sponsorships and affiliations, and therefore, our staff members are contractually required to have zero industry ties. Our dedicated research team has compiled practical facts backed only by science. Suggested supplements are based on data alone, so you can rest easy knowing you’re not wasting money on false claims.

What's included in each Supplement Guide?

Evidence-based recommendations

We’ve broken down our recommendations into five descending sets of priorities based on scientific evidence:

  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.
Our science-backed advice will let you figure out exactly what you should take, what you may want to consider taking, and what's definitely a waste of money.

Directions on the optimal dosage, timing, and combination of supplements

We provide you with the following step-by-step guidance on supplements:

  1. Why you should take it
  2. How much you should take
  3. When you should take it
  4. Good and bad supplement combinations

You probably want to stay current on the research in your field, to be most helpful to patients and clients.

Unfortunately, no one person has the time or expertise to analyze the thousands of nutrition studies published each month.

Our team is equipped for the job. Examine has been at this since 2011, and we collectively have degrees in nutrition, medicine, exercise science, public health, pharmacology, toxicology, biophysics, neuroscience, and more. Between us, we can analyze any nutrition study. If we need further help, we bring in outside experts.

With our guides, you can quickly reference the latest findings, all neatly packed in targeted health topics that can benefit your clients and that also make it easier for you to generate content for talks, articles, newsletters, and social media.

No. Though health professionals use the guides to stay on top of the research in their fields, our guides are designed from the get-go to also serve the needs of people with their own health goals. We use clear organization and simple yet precise language to make the information accessible without watering it down excessively.

Even if you’re not a health professional, you likely have friends and family that rely on you for health advice. Using the guides allows you to keep up to date on supplementation research related to that health topic, and if you read dubious claims online, you’ll likely have recent evidence in mind (or at hand, at least) to clear the fog for everyone.

We offer an unconditional 60-day money-back guarantee on all our products. Should you be unhappy with the Supplement Guides for any reason, simply email us at, and we will refund your purchase.

I turn to Examine for quick, reliable data on a whole host of health topics. It's rare to find such guidance that is meticulously researched yet easy-to-digest, but Examine manages to deliver on both. I strongly recommend it as a trusted resource.

James M. Gaylor MD | Health Policy Fellow, Georgetown | Attending Physician, Department of Emergency Medicine

Examine is my new favourite go-to for current research. Instead of spending my time on the tedious and time-consuming task of finding and reviewing abstracts, Examine is tailored to my specific interests and delivers just what I need to know – the key takeaways from the latest research. The brief summaries invaluable; they are clearly written, concise, and help me stay up to date with the research that is most relevant and important to me.

Gillian Mandich PhD | Health Science researcher

When I was a grad student, it was easy for me to keep up with the latest research in exercise, nutrition, and supplementation. Of course, staying current was essential to my development as a scientist, writer, and coach. Nowadays, though, with the epic rate of research output in our field PLUS everything going on in my life (i.e., parent of four young children, founder of two businesses, author, competitive athlete) staying up to date feels impossible.

That’s why I subscribe to Examine. Every month the Examine team pores over the latest publications to find, and summarize, the research I most want to know about. All that for just a few bucks. If you work in health and fitness, you won’t find a better cost-to-value ratio anywhere.

John Berardi PhD, CSCS | Co-founder Precision Nutrition | Advisor to Apple, Nike, Equinox, and Titleist

Examine’s updates help me to stay on top of current research on supplements and diet trends. Their in-depth summaries are a great way to get “the lay of the land” quickly and efficiently.

Jennifer Sygo RD Cleveland Clinic Canada | Performance Toronto Raptors

I tend be really busy these days which makes it really challenging to keep up with the latest research. If you know science, you know that reading and evaluating research is not as simple as reading an abstract. There is a great deal of nuance involved. Put more succinctly, I just don't have the time to do it justice.

So, what do I do? I use Examine. It consists of great summaries I can trust. It is invaluable for people like me who have a strong desire to keep up with science, but not a great deal of time to give it the proper study!
