However, there are special nutrients that can be found in nature which promote insulin function and maintain blood sugar levels within the normal range. Besides the nutrients D-Chiro-Inositol and manganese, the formula offered by Swanson also contains the patented and scientifically validated Chirositol™, naturally derived from carob juice, together with synergistic manganese for complete and natural support.
