From my readings about magnesium I am certain that "OFFICIAL" recommendations are as far from optimal as are "official" recommendations for Vitamin D3. I'm certainly not limiting my intake of magnesium or vitamin d3 to "offficial" RDA's and I think anyone who suggests "official" RDA's are the optimum levels the body works best with simply doesn't understand the history of why we have RDA's or what they are intended to achieve.
