“The lef site pretty much state that multi-vitamins which you take once per day, don’t really do anything. It’s just a waste of money? “
I would encourage you to navigate the LEF site as it is an enormous source of information per the efficacy of supplementation in the form of popular articles and scientific journal abstracts number perhaps in the ten’s of thousands. In recent times within the last decade and a half there has been a great proliferation of information on supplements (vitamins, minerals, herbs, amino acids, etc.) Supplementation has become a huge commercial success and hence the motivation to proliferate information through funded research. Just look at the drug stores, twenty five years ago you may have observed a small shelf dedicated to vitamin supplements, now you will find entire sections dedicated to supplements. I am personally glad to see this because in good old days many of us in the scientific community felt that supplementation was helpful but there was not a great deal of research to back up this belief.
In my experience taking supplements once a day works fine.
“P.S. I take in mind all possible commercial interests of “lef”.”
You got that one right!
