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.

Please note. Primary Care Evidence Guide is a publication. It is not a medical practice, clinic or healthcare provider, and nothing here is medical advice. This web address was used by a different organization in the past, and this publication has no connection to it; see our independence notice. Some links earn us a commission, which never changes what we write; see the affiliate disclosure and how we work.
