Pinitol (D-pinitol)

This is an excellent supplement which has a lot of potential for athletes and individuals involved in a fitness routine. It is known to be contained in pine wood and legumes but is derived from soy for manufacturing. It has been shown to decrease blood sugar levels and free fatty acid levels (5) (that is great news for someone trying to lose body fat). It is a patented ingredient and has been registered with the FDA by Humanetics. In fact, it has several patents on it including U.S. Pat. No. 5,124,360 which describes administration of a supplement for the therapeutic treatment of insulin-resistant type II diabetes comprising of D-chiro-inositol. Two of its most significant effects for athletes is that it increases glucose uptake by the muscle cell and enhances glycogen storage (carbohydrate storage in the muscles). This can lead to greater energy levels and a more stable blood sugar level (not to mention better “muscle pumps”). It has been shown in clinical research that pinitol can improve insulin function by increasing insulin sensitivity (thereby allowing insulin to work more efficiently). Pinitol has been shown to decrease stored fat. Another study published in the British Journal of Pharmacology showed the insulin like actions of pinitol. Although this was an animal and in-vitro study, it still shows some possible benefits. This insulin-mimicking compound is quickly becoming standard issue in blood sugar regulating supplements. It is already showing up in creatine transport formulas, which is an interesting use for this compound, since insulin helps transport more creatine into muscle tissue where it is utilized best to support the reproduction of ATP (energy). A good dose is 100 mg taken 1-3 times daily with meals, preferably after a workout
