This seems to be the week of omega-3 oil publications. First there was a PATHETIC study whose authors claimed they had proved that O-3 supplements increase prostate cancer. http://jnci.oxfordjournals.org/content/early/2013/07/09/jnci.djt174.abstract.

Supplement Content and Purity

Health advocate Gary Null has provided an unintentional educational lesson for those of us using dietary supplements. Taking one of his own products, he developed vitamin D toxicity. As there have been only a few cases of vitamin D toxicity ever reported, there is an inevitably interesting story behind this announcement. The story is that […]
