Personally, I only take a multi-vitamin and an extra Vitamin D, and I don’t do it religiously every day. I do this because even with a balanced diet, modern food tends to be lacking in all essential vitamins.
Beyond that I frown on most supplements. It can be costly, can get very complicated, and generally is not all that well supported from a medical scientific standpoint. Some people have special needs, of course, such as the poster who mentioned anti-inflammatory supplements.
Although I do not approve of their use, I have known a woman bodybuilder who regularly took steroids. I cannot deny that they were effective for her. She was several times stronger than me and much stronger than the average man. (She could bench press 305 pounds!) The steroids did not seem to hurt her any, but it seemed risky to me.
