Trigonella foenum-graecum, commonly known as fenugreek, is a popular herb in Arabic regions and India. It has traditionally been used to enhance libido and masculinity.
Fenugreek has also been used to alleviate blood sugar metabolism problems like diabetes.
Fenugreek tea has also been recommended to new mothers to enhance milk production. Though evidence for this claim is limited, it seems to be accurate. One human study has shown that fenugreek supplementation can also enhance testosterone, but since additional evidence shows conflicting results, further evidence is needed to confirm this effect.
Fenugreek’s most well-known compound is 4-hydroxyisoleucine, which works to normalize glucose metabolism. The other compounds, called trigonelline, galactomannan, and trigoneosides, also work together to provide benefits for blood sugar.
Supplementing fenugreek may cause body secretions, including urine, to smell like maple syrup. This is due to a metabolite called sotolon.
