Some work; some don’t. Google Scholar is a good way to find out whether testing’s been done. Here are 2 less time-consuming ways 1) https://ods.od.nih.gov/factsheets/list-all/ 2) https://examine.com/ The other thing to watch out for is whether the bottle you’re buying actually contains what it says it does. The only verifying organizations I know of are NSF and USP. Manufacturers have to pay for those lab tests, and if they do, they post NSF or USP logos on the bottles. If you just look for “natural” or “organic,” you won’t find anything about the presence or absence of the supposedly active ingredient. As jmp242 said, there’s no regulation in the USA, so there’s a lot of snake oil.
Good points, I just wanted to mention another database that is useful for finding information about supplements based on actual research studies. Unfortunately it requires a subscription but some Universities and Libraries can provide access.
