Science has revealed that proper mineral ratios are needed in the diet. The calcium to magnesium ratio has been widely known to be 2:1 for some time. However, many in the industry have equivocally interpreted this to mean 2:1 potency or weight, when in fact it has to do with molar ratios. Di-Calcium/Magnesium Citrate Complex contains calcium and magnesium reacted to citric acid, in their correct molar ratios. Moreover, since the calcium and magnesium are contained within the same complex, everything absorbed is absorbed in the proper 2:1 molar ratio, without one mineral competing against the other. Give true molar ratios a try!
