Mineral availability for absorption in the human body is an important parameter when choosing a mineral source for food supplements. GLUCONAL, PURAMEX and PURACAL minerals have shown to be highly bioavailable mineral sources in several in-vivo and in-vitro studies. The bioavailability of most mineral salts depends on the circumstances in which the supplement is taken, which results in a recommendation on the product label to take the supplements with a meal. With mineral lactates and gluconates, this is not necessary; their absorption is just as high when taken with a glass of water only as when taken with a meal.
