Chromium is a metallic element that humans require in very small amounts. It is commonly available in two forms are commonly available as supplements: glucose-tolerance factor (GTF) chromium and chromium picolinate. Chromium is a metallic element that humans require in very small amounts. It is an essential part of metabolic processes that regulate blood sugar, and helps insulin transport glucose into cells, where it can be used for energy. Chromium also appears to be involved in the metabolism of carbohydrate, fat, and protein. Chromium can also help raise HDL (“good”) cholesterol levels, and may play a role in preventing heart disease. The RDA for Chromium is 25 mcg/day for males and females aged between 19 and 50; 35 mcg per day for men over 50 and 25 mcg per day for females over 50; 20 mcg per day for pregnant females over 19, 30 mcg per day for lactating females over 18, 45 mcg per day for 0-6 months infants , 5.5 mcg per day for 1-3 years children , 11 mcg per day for 4-8 years children, 15 mcg per day for young males aged between 9 and 13, 25 mcg per day for young females of the same age, 21 mcg per day for teen males aged between 14 and 18 and 35 mcg per day for teen females. Deficiencies of chromium can produce problems in blood sugar metabolism, and contribute to other symptoms such as anxiety or fatigue. Altered cholesterol metabolism, accelerated atherosclerosis, decreased growth in young people and delayed healing time after injuries or surgery can result from chromium deficiency. On the other hand, researchers have not found any toxic effects that result from taking high doses of chromium.
