Fenugreek and Insulin Aspart, a caution.
Fenugreek can lower glucose in people with diabetes and may improve glycemic control when added to usual therapy, including insulin. Insulin aspart acts quickly around meals, so extra glucose-lowering from fenugreek can increase the chance of post-meal or delayed hypoglycemia. Risk is higher if meal carbohydrates are reduced, meals are delayed, or insulin doses are not adjusted.

Caution
What is happening. Fenugreek can lower glucose in people with diabetes and may improve glycemic control when added to usual therapy, including insulin. Insulin aspart acts quickly around meals, so extra glucose-lowering from fenugreek can increase the chance of post-meal or delayed hypoglycemia. Risk is higher if meal carbohydrates are reduced, meals are delayed, or insulin doses are not adjusted.
Mechanism. Fenugreek seed fiber can slow carbohydrate absorption, while 4-hydroxyisoleucine and other constituents may stimulate glucose-dependent insulin release and improve insulin signaling. These effects can add to rapid-acting insulin aspart's prandial glucose-lowering.
Recommendation. Do not add fenugreek to insulin aspart without checking glucose more often. Monitor before meals, 2 hours after meals, and at bedtime for the first 1-2 weeks, and discuss whether meal insulin needs adjustment. Carry fast carbohydrate and treat glucose below 70 mg/dL promptly.
