Safety Notes

It is likely safe for most adults to use fenugreek for a short time. Not enough studies have been done to say whether it is safe to use for a long period. Fenugreek may be unsafe for use by children and during pregnancy.


Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse, such as:

  • People taking anticoagulants should talk to their doctor before taking fenugreek. It may increase risk of bleeding.
  • People with diabetes should talk to their doctors before taking fenugreek. It may cause blood glucose to become too low when it is taken with medicine to control diabetes.
