However, two new studies indicate that the quantity of chromium in any supplement may not be nearly as important as the mineral’s chemical form.Īt the Experimental Biology 2005 meeting in San Diego last week, Robert DiSilvestro and Emily Dy of Ohio State University reported data indicating that only the picolinate form of chromium-one of the four kinds in most commercially available supplements-is absorbed well by the body. DiSilvestro Broccoli is one of the richest natural sources of chromium-a cup delivering almost 10 times as much as an equivalent portion of green beans, potatoes, or orange juice.īecause chromium concentrations in most foods are far too low to have much of an effect on blood sugar, health practitioners typically recommend that people augment their diets with mineral supplements.
All values are increases over background, which is the amount obtained from the diet. The middle two are both forms of nicotinate-the pink bar denoting the type also known as GTF, and the orange bar showing data for the form with additional amino acids. Table shows the relative absorption of four common forms of chromium used in supplements reported in new Ohio State study. It can help people exhibiting prediabetic symptoms and those with full-blown type 2 diabetes, the non-insulin-dependent form of the disease. Chromium is a mineral that’s been gaining some hard-won respect, primarily for its demonstrated ability to normalize blood-sugar concentrations ( SN: 5/1/04, p.
