Chromium
The functioning of chromium in the body is less understood than that of most other . It enhances the actions of so it plays a role in carbohydrate, fat, and protein . Currently, the results of scientific studies evaluating the usefulness of chromium supplementation in preventing and treating Type 2 diabetes are largely inconclusive. More research is needed to better determine if chromium is helpful in treating certain chronic diseases and, if so, at what doses. If a deficiency of chromium occurs in the body, signs and symptoms include weight loss, peripheral neuropathy, elevated plasma glucose concentrations or impaired glucose use, and high plasma free fatty acid concentrations. Although toxicity of the mineral is a low risk in humans, it can cause DNA damage, organ damage, and renal problems. Tissues that are high in chromium include the liver, spleen, and bone.[1]
Dietary Reference Intakes for Chromium
The recommended intake for chromium is 35 mcg per day for adult males and 25 mcg per day for adult females. There is insufficient evidence to establish an UL for chromium.

| Infants (6-12 months) | 5.5 |
| Children (1-3 years) | 11 |
| Children (4-8 years) | 15 |
| Children (9-13 years) | 25 (males), 21 (females) |
| Adolescents (14-18 years) | 35 (males), 24 (females) |
