A lot of what's been mentioned aren't really supplements. Actual foods should be a lot more bioavailable, but if you can't get something that way and are really deficient it could make all the difference getting it in a synthetic form.

I used to buy into more of this so I have taken a number . The only supplement I ever noticed taking was ZMA, one Victor conte came up with I guess. No idea if it has the benefits it claimed, but it definitely helped with sleep and gave me vivid dreams, so for that alone was good, the dreams were almost to good. Could be I wasn't getting enough magnesium around the time, apparently that's common. Nothing will stop the man who wasn't there, jacked up mice and a musical fridge, except time or proper drugs, that I do know.
