Well, I usually research a supplement before I try it out, multiple websites and reviews. Also they are not that expensive, so burning $15-20 is worth it if I can find something that actually works.
Since I don't like to take too may pills, I cycle them during the year. For example for the summer, I take Astaxanthin. Beside a bunch of things

it has a really neat side effect, it doesn't let you get sunburnt. It really does work that way. I used it all last summer. So if you are light skinned, take it for the summer and you can save money on sun lotion...
