Chromium

Because it is involved with the metabolism of glucose, chromium (sometimes  also called glucose tolerance factor or GTF) is needed for energy. It is also vital in the synthesis of cholesterol, fats, and proteins. The essential mineral maintains stable blood sugar levels, through proper insulin utilization, and can be helpful both for people with diabetes and those with hypoglycemia. Studies have shown that low plasma chromium levels can be an indication of coronary heart disease. Additional chromium is needed during pregnancy because the developing fetus increases demand for this mineral. Chromium supplements can help an expectant mother maintain healthy blood sugar levels during pregnancy.
