In addition, foods containing this trace element are not especially popular with many people in the US.Īnd the amount of chromium in these foods can vary, depending on where they are grown, or how they are sourced and processed. The typical American diet, high in refined foods such as flour and sugar, supplies little chromium. Supports a Healthy Metabolism and Energy Levels.Controls Hunger and Prevents Weight Gain.Scientifically proven benefits of Chromium Picolinate.Why Should You Choose Chromium Picolinate (CrPic)?.

the synthesis technique of chromium picolinate according to claim 1 and 2, it is characterized in that: above-mentioned reaction process is to carry out in the autoclave that is liner with the tetrafluoroethylene. Patent number 5677461 discloses the chromium picolinate synthesis technique, it obtains the 2-chromium picolinate by 2-pyridine carboxylic acid and chromic salts reaction, directly generate the technology of chromium picolinate by 2-pyridine carboxylic acid and chromic salts generation complex reaction, because the 2-pyridine carboxylic acid costs an arm and a leg, holding at high price of the feasible 2-chromium picolinate of producing directly has influence on 2-chromium picolinate applying in fodder additives and foodstuff additive.ģ.
