GTF Chromium supports the body’s metabolism as well as maintains normal insulin levels. Having normal insulin levels is important because insulin is fundamental to having a healthy blood sugar level. GTF stands for “glucose tolerance factor” and it requires chromium as its central atom. GTF Chromium is pertinent to the Glandular System. Chromium is important to help create fatty acids, lecithin, cholesterol, and lipoproteins for the liver. Someone lacking chromium in their diet may experience a significant increase of blood fats in their system because the liver is unable to filter them out alone.
