4- hydroxyisoleucine is an amino acid derivative that assists the pancreas in production of insulin. Studies have shown that adding fenugreek to your diet reduces fasting blood sugars and improves after-meal glucose tolerance significantly. 4-hydroxyisoleucine works by two separate mechanisms: It has a direct, stimulating effect on insulin production for those who wish to increase their glucose metabolism and helps to reduce glucose resistance and the uptake of glucose, thereby reducing overall blood glucose levels. Several studies with animals and with human cell cultures demonstrate this extract’s positive effect on reducing postmeal glucose levels—with little or no increase in blood insulin concentrations— a clear indictor of improved insulin sensitivity.

Several studies show that the free amino acid 4-hydroxyisoleucine plays a valuable role in insulin-promotion and glucose regulation. 4-hydroxyisoleucine stimulates insulin secretion, thereby limiting the extent to which blood glucose (the glycemic index) is elevated. Elevated blood glucose after meals leads to increased production of body fat. 4 hydroxyisoleucine promotes insulin secretion and inhibits the rise of blood glucose, thus helping to reduce body fat production. 4-hydroxyisoleucine exhibits a specific effect on the islets of Langerhans in the pancreas. These cells are directly responsible for insulin production. Most significantly, the effect of 4-hydroxyisoleucine is glucose dependent. The higher the level of blood glucose, the greater the insulin-promoting response elicited by 4 hydroxyisoleucine. Thus 4-hydroxyisoleucine exhibits a significant regulating effect, which corresponds with the insulin needs of the body at any given time. This makes this compound “adaptogenic,” responding to the particular needs of the body at any given time.
