Dont want to sound cocky or wise guy, above I just stated facts.
Links from other forums are not really helpfull as most are bro science an product pushers.
If you look at some medical studies you will find the answers. Many guys here have medical background, and have extensively studied this subjects, so there is not much of a discussion here.
Sorry, dont really have time to pull some documents, but like I said if you are willing you will find the right answers... Just steer away from the other forums, look for medical sources.
