I’ve done an exhaustive study on what are the best multivitamins for the male side of the human family. You can read about that material here. I studied over 118 to be exact at quite some expense to myself.
I found some very interesting things. One of which is the fact that most vitamins out there for men are crap. Most are synthetic. It’s especially disheartening to see certain brands advertised on TV that are terrible. The best ones I found are not very well known. They are actually quite anonymous, which is interesting only that it means only the sincere seeker of truth will find them.
Secondly, I found out that most are not even assimible by the body! This fact alone is quite astonishing. The government here in the U.S. has taken some steps to regulate more the vitamins out there with controlling GMP compliance and certifying quality, but what you need to do essentially test yourself. The aforementioned page will help you in that regard.
