Start with what you need
Four sections, each with its own guide page and every article on the subject.
Preparing for Primary Care Visits
Checklists, note-taking tips and question lists for getting ready for an appointment, messaging your clinic, and following up on results, referrals and care plans.
See the visit guides →Judging Online Health Information
How to check the source, the author, the evidence and the wording of health websites, social posts, testimonials, statistics and guidelines.
Learn to check a claim →Blood Sugar and Weight Products
Reviews and comparisons of blood sugar, berberine, weight-loss and GLP-1 related products and programs, with background on the subjects they address.
Read the reviews →Other Supplements and Buyer Checks
Brain health, men’s health, skin and other wellness products, plus how to verify a seller and what the return and refund terms really say.
Check before you buy →How we work
The same three steps go into every guide and review on this site.
We read the research
For a product, we look up the published studies on each active ingredient and check whether the amounts on the label match what was tested. When the research is thin or mixed, we say so.
We read the fine print
Who sells it, how to reach them, what it costs with shipping, and what the refund terms require. These are the details that decide whether an order goes well.
We send you back to your clinician
We are health writers, not doctors. When a question depends on your own history or medicines, we say that plainly and suggest what to ask.
