is chromium picolnate necessary for good health?

Hello! Can anybody explain to me if and why chromium picolnate is necessary for good health? Thank you!

Hi there! Chromium is an essential mineral to health. It may be found naturally in small amounts in brewer's yeast, black pepper, liver and lobster. Chromium is very important to good health due to its role in supporting the insulin sensitivity of the body's tissues. Insulin is vital for the metabolism of carbohydrates, proteins and fats. When Chromium levels drop, insulin resistance occurs and a wide range of negative health consequences are likely to ensue. They are obesity and poor physique, heart disease and hypertension.
