Experimental and clinical studies have demonstrated the antidiabetic properties of fenugreek seeds. The active ingredient responsible for the antidiabetic properties of fenugreek is in the defatted portion of the seed that contains the alkaloid trogonelline, nicotinic acid and coumarin. Fenugreek contains six compounds that help regulate blood sugar levels. Modern research shows that fenugreek seeds not only lower blood glucose but reduce insulin levels, total cholesterol and triglycerides, while increasing HDL (the good cholesterol).
