Hi, I've never used it but I'm sure some of the people here have! As far as supplements, I take a multi-vitamin (a senior one even though I'm only 24, because I think it has the right balance for me with vitamin b and no iron

), calcium and co-q 10. Also potassium if I'm getting leg cramps. I know a lot of people here take a lot of supplements so I'm sure you'll get some good responses. There is also a vitamin forum here:
