Chromium is an essential nutrient, but the inorganic chromium is virtually unabsorbable and has no nutritional value. Studies suggest that chromium picolinate, as an organic chromium source, is the most effective for a living organism.
Natural inorganic chromium is water-soluble and its biological activity is very low, but organic chromium is lipophilic and very active on tissues. Evans and Bowman(1992) reported that chromium compounds affect insulin and the internalization of cultured muscle cells and that chromium picolinate produces the most significant increase in the uptake of glucose and leucine into skeletal muscle. |
