Chromium picolinate

タイトルまたは説明

Chromium picolinate appears as fine purple crystalline powder with good fluidity. It is chemically stable at room temperature and is slightly soluble in water but insoluble in ethanol, wherein the chromium is in the trivalent form. The whole molecule structure is electrically neutral and has hydrophobic properties. Therefore, it is possible to perform the trans-membrane absorption on the intact structure with the molecular structure being similar to the GTF part. In ***7, Toepfer thought that GTF is the biologically active form of chromium with its structure being the complex formed between nicotinic acid chromium and aspartic acid, glutamic acid, glycine and cysteine. The GTF-like structure of chromium picolinate class determines its own excellent absorption rate and can more effectively play its biological function. It is reported that the absorption rate of formulation of ordinary chromium was about 0.5% while the absorption rate of chromium is 2%*5% (Anderson, ***6). 
Chromium picolinate is a health supplement for strengthening muscles and promoting weight. It can increase the amount of the active AMP protein kinase (AMPK) related with metabolism pathway inside the skeletal cells, thereby improving energy balance and insulin function. The main effects are as follows:
1, It can improve the proportion of lean meat, reduce fat as well as improve carcass quality.
2, It can improve the capability of stress resistance and immunity. Stress can cause reduced animal production while niacin chromium, through its anti-stress effect, may increase the production of animal products.
Chromium is an essential mineral, it is the indispensable substance for the release of active insulin during the carbohydrates, fat and protein metabolism. In August ***5, the US Food and Drug Administration (FDA) had approved the production of chromium picolinate, and confirmed that it is safe for being applied to the treatment of human insulin resistance and type II diabetes. The main basis for FDA for made this judgment was the early, randomized, and double-blinded and placebo therapy conducted by Dr. Cefalu who had shown that chromium picolinate can significantly improves the insulin sensitivity of the patients of the high-risk diabetic.
The dietary reference Intakes amount of chromium (adults) provided by our country is AI = *0ug per day, UL= **0 ug per day for Chinese Residents.
In the "Declaration of nutrient supplements and review Provisions", the minimum amount of chromium is *5ug/day while the maximum amount is **0ug/day.
