Fenugreek is a plant with seeds that are antidiabetic. Fenugreek seeds can be consumed powdered as a spice, as a beverage (powder mixed with hot water), as whole seeds, or as supplements.
Studies in type 1 and type 2 diabetics have found that fenugreek seed powder reduces blood sugar, insulin resistance and HbA1c, and increases carbohydrate tolerance.60-64
For example, in type 2 diabetics, 10 grams per day of fenugreek powder mixed with hot water led to a 25% reduction of fasting blood sugar in 8 weeks.60
The optimal amount per day is unknown, but a few grams per day seems adequate based on the science. I’d personally stay in the 1 to 10 gram per day range, not more.
Because fenugreek is more commonly consumed in Asia, it may be easier to find in an Asian grocery store. It can also be purchased online.
