| Substance | Interaction | What happens |
|---|---|---|
| Berberine | Caution | Additive glucose-lowering effect that can increase the risk of hypoglycemia, especially in people also taking antidiabetic medication. details → |
| Black Seed Oil | Caution | Both supplements are well-documented oral hypoglycemics in human trials. Taken concurrently, especially alongside antidiabetic medication... |
| Chromium | Caution | Fenugreek and chromium are both commonly stacked for blood sugar and metabolic support, and each independently lowers fasting and postprandial... details → |
| Dulaglutide | Caution | Fenugreek fiber can slow carbohydrate absorption and may lower glucose modestly. Dulaglutide also lowers glucose and delays gastric emptying, so... |
| Garlic Extract | Caution | Fenugreek has documented, though mostly preclinical, antiplatelet effects, and garlic extract is a well-established platelet aggregation inhibitor... |
| Glimepiride | Caution | Fenugreek extracts lower fasting glucose and HbA1c in type 2 diabetes meta-analyses. Glimepiride forces pancreatic insulin release. The additive... details → |
| Glipizide | Caution | Fenugreek extracts lower fasting glucose and HbA1c in type 2 diabetes meta-analyses. Stacked on glipizide, which already forces pancreatic insulin... details → |
| Glyburide | Caution | Fenugreek extracts lower fasting glucose and HbA1c in type 2 diabetes meta-analyses. Glyburide is the longest-acting US sulfonylurea and already... details → |
| Insulin Aspart | Caution | Fenugreek seed fiber and constituents may lower fasting or post-meal glucose in diabetes studies. Because insulin aspart is rapid-acting... details → |
| Insulin Glargine | Caution | Fenugreek seed fiber and constituents may lower fasting or post-meal glucose in diabetes studies. Because insulin glargine provides basal insulin... details → |
| Insulin Lispro | Caution | Fenugreek seed fiber and constituents may lower fasting or post-meal glucose in diabetes studies. Because insulin lispro is rapid-acting... details → |
| Liraglutide | Caution | Fenugreek fiber can slow carbohydrate absorption and may lower glucose modestly. Liraglutide also lowers glucose and delays gastric emptying, so... |
| Metformin | Caution | Fenugreek seed extracts (typically standardized to ~50% galactomannan fiber and 4-hydroxyisoleucine) lower fasting glucose and HbA1c in randomized... details → |
| Pramlintide | Caution | Fenugreek seed fiber and constituents may lower fasting or post-meal glucose in diabetes studies. Pramlintide is used with mealtime insulin and... details → |
| Semaglutide | Caution | Fenugreek fiber can slow carbohydrate absorption and may lower glucose modestly. Semaglutide also lowers glucose and delays gastric emptying, so... |
| Testosterone | Caution | Fenugreek extracts (especially standardized products like Furosap) modestly raise free testosterone in men in small clinical trials. Layering... details → |
| Tirzepatide | Caution | Fenugreek can lower glucose and slow carbohydrate absorption, while tirzepatide lowers glucose and slows gastric emptying. Combining them can worsen... |
| Vanadium | Caution | Taken together, vanadium and fenugreek produce an additive blood-glucose-lowering effect documented in experimental diabetic models, where their... |
| Warfarin | Caution | Fenugreek aqueous extract inhibits coagulation in vitro and significantly prolongs prothrombin time. A well-documented case describes a... |
| Iron | Timing Sensitive | Fenugreek's high soluble fiber and polyphenol content can bind non-heme iron in the gut and reduce its absorption when taken together. |
| Moringa | Synergy | Stacking moringa with fenugreek can produce a larger drop in blood glucose than either alone because they hit different steps of glucose handling:... |
| Tribulus Terrestris | Synergy | Tribulus and fenugreek are both used in male vitality and libido formulas, with complementary effects on sexual function and, for fenugreek, some... |
