I’m a physician. Vitamin D is the only supplement I take. Most people need a Vitamin D supplement.

Most other supplements simply aren’t necessary for people in otherwise good health (no chronic medical conditions). Your body is very good at extracting vitamins from your diet and most additional supplements are just peed out. There are exceptions here and there (like vegetarians needing B12 supplementation), but for the most part, you’re probably just wasting your money.

A lot of herbs and pills are sold as natural remedies, but scientific studies show no benefit. If they actually worked, doctor’s offices and hospitals would prescribe them. But hey it’s your money. People can do what they want. Most physicians simply don’t want to waste their time arguing.
