      Chromium boosts the effectiveness, which helps keep your blood sugar at optimal levels. It also participates in the metabolism of carbohydrate, fat and protein. Chromium polynicotinate supplements are safe for most people, but they can interact with medications or lead to problems if you have existing health conditions.
Supplemental minerals have a hard time passing through the intestinal wall, which means only a small amount is absorbed into your bloodstream. As a result, minerals are often combined with other substances that help escort them through the wall.
Niacin boosts chromium’s absorption, and when the two are combined, they create a supplement called chromium nicotinate or chromium polynicotinate. In large, therapeutic doses, niacin can cause side effects, but chromium polynicotinate doesn’t contain much niacin.
