I take iron (I'm pretty careless about what dose I grab) to control anemia, and vitamin D (gelcaps because Dr. My Uncle told me they're better, 5000 IU/day because a blood test showed me D-insufficient on a lower dose). You're supposed to take iron with food but I don't get the stomach upset problem if I just take it before bed and it's easier to remember that way. I don't care about brands qua brands, although I'm probably influenced by packaging when there are several options within my parameters.

For a while I took magnesium to see if that would help reduce fasciculations. It didn't help so I stopped when I ran out. I think that's the only one.
