Professional Supplements & Nutritional Products Since 1998

MedCaps IS™ is an extraordinary combination of herbal and nutrient support for healthy glucose metabolism. It features concentrates of fenugreek, Gymnema, and bitter gourd, the addition of high levels of vanadium along with select B vitamins and the mineral, chromium. This formula provides nutritional support for glucose and insulin metabolism and supports healthy blood lipid levels already within the normal range*

  • Supports Healthy Glucose Metabolism*
  • Supports Healthy Insulin Sensitivity*
  • Supports Healthy Blood Lipid Levels Already Within The Normal Range*

Thiamin activates glyceraldehyde phosphate dehydrogenase (GAPDH). Decreased availability of this enzyme has been implicated in diabetes complications such as blindness, nerve damage, kidney failure, stroke, and cardiovascular disease.[1] Thiamin repletion in the case of a six-year-old girl with diabetes caused by a genetic mutation affecting thiamine transport demonstrated its benefits.[2] Thiamin deficiency may cause diabetic neuropathy by decreasing transketolase, needed for normal myelinization, and thiamine monophosphatase, needed for primary sensory neuron function.*[3]

Niacin is required for lipid metabolism, tissue respiration, and glycogenolysis. It may preserve and protect Beta cells.[4] Niacinamide improved insulin secretion in lean diabetics who had failed drug treatment.*[5]

Chromium and Biotin synergistically improve glucose tolerance.[6,7] Biotin, in large doses (5-15 mgs) enhances the effects of enzymes involved in glucose metabolism. One small study demonstrated the reversal of diabetic neuropathy.[8] Chromium polynicotinate, preferred for its bioavailability and biological activity may increase insulin receptor sensitivity and enhance glucose transport. Anderson, et al. showed 1000 mcgs of chromium stabilized blood sugar in two months along with insulin and cholesterol level improvement.*[9]

Vanadyl Sulfate may reduce hepatic gluconeogenesis and “mimic” insulin’s effect.[10] In rats, vanadyl sulfate was also shown to alter the expression of genes dysregulated in diabetes.*[11]

Fenugreek Seed and its constituent, 4-isoleucine appear to directly stimulate insulin.[12] The combination of fenugreek with vanadium appeared to normalize altered membrane-linked functions and GLUT4 distribution.[13] Fenugreek also lowered high serum cholesterol and triglycerides.*[14]

Bitter Gourd (aka. bitter melon) contains an insulin-like polypeptide shown to exhibit hypoglycemic effects[15] with an onset of action between 30-60 minutes and a peak effect at about 4 hours.[16] It is approved as an antidiabetic drug in China.*[17]

Gymnema Sylvestre reduces fasting blood sugars, glycosylated hemoglobin (HbA1c), and glycosylated plasma protein levels and thus insulin requirements in Type 1 diabetics by reducing glucose absorption in the intestine, stimulating pancreatic beta cell growth and possibly increasing endogenous insulin secretion as suggested by an increase in C-peptide levels. Gymnema was shown to also reduce serum triglycerides, total cholesterol, VLDL, and LDL.*[18]
