CBlock contains Trimplex, a laboratory tested extract of the white kidney bean (phaaseolus vulgaris) which has been shown to inhibit the absorption of starch from food. Trim Plex inhibits the production of the alpha amylase enzyme, which breaks down starches into sugars for digestion. CBlock goes even further, with added chromium and vanadium, two elements that help regulate blood sugar levels. This maintains your metabolism and trims your cravings for carbohydrates. CBlock was designed to supplement weight loss programs that include a healthy diet (low carb diet and others) and regular exercise. These factors will vary weight loss. CBlock is ephedra free, caffeine free and stimulant free. CBlock inhibits the absorption of starch from starchy foods, including: pasta, potatoes, breads, pastry, rice, wheat, oats (oatmeal), wild rice, barley, buckwheat (kasha), rolls, muffins, cereals, sweet potatoes, peas, corn, beans and lentils.
