The other one I do take occasionally still is B-12. Even trying to eat lots of fermented foods, I'm not sure modern diets can reach the optimal level. B-12 is made by bacteria, so modern sanitation and hygiene have greatly reduced the amount we consume.

I definitely took multivitamins. My preference is for the food based ones over the synthetic ones.

I took CoQ10 while recovering from a joint injury. That's more treatment than supplement, though.

I know at various times I've taken B-complex supplements, fish oil, algal oil, iodine, vitamin K, biotin, vitamin E, and probably a few others.
