Unlike prescription drugs, supplements in the U.S. aren’t regulated by the FDA. As a result, some products may not contain the ingredients listed on their labels. For safety, look for supplements verified by third-party testing and seek advice from a healthcare provider, dietitian, or pharmacist.

Fenugreek can help reduce A1C levels and blood sugar in people with diabetes. It does this by improving how the body uses insulin, helping the cells take in glucose, and controlling enzymes that break down carbs. Fenugreek also slows down how fast food leaves the stomach, which helps keep blood sugar stable.¹

The best way to use fenugreek for diabetes is by taking about six grams of powdered fenugreek seeds every day. It can take about 10 to 30 days to start seeing lower blood sugar levels, but regular use can help keep blood sugar in check over time. More research is needed to fully understand all the ways fenugreek helps with blood sugar, but the existing evidence is promising.¹

Fenugreek in Ancient Medicine

Fenugreek, native to the Mediterranean and parts of Asia, was first mentioned in ancient Egyptian texts like the Ebers Papyrus around 1500 BC. In different regions, it’s called “methi” in Hindi, Urdu, and Punjabi, and “hulba” in Arabic.²

Fenugreek has been used for thousands of years in traditional medicine, especially in ancient Egypt, Greece, and India, where it was valued for its ability to support overall health. It was commonly used as a general tonic to aid digestion, improve metabolism, and relieve symptoms of uncontrolled blood sugar.²

In addition to its digestive and metabolic benefits, fenugreek has long been used to reduce inflammation and alleviate pain. The seeds were applied as a poultice to relieve joint pain and reduce swelling. Ancient texts also mention the use of fenugreek for treating nerve problems—a common complication of diabetes.²

Fenugreek for A1C

Fenugreek has been studied for its potential to help lower A1C levels, a measure of average blood sugar over the past two to three months, by improving blood sugar control in people with type 2 diabetes.

Fenugreek appears to help lower A1C in several ways:³

• Increases insulin production: Fenugreek may help the pancreas make more insulin, which is a hormone that helps lower blood sugar.
• Slows sugar absorption: The fiber in fenugreek can slow down how quickly sugar from food enters the bloodstream, helping to prevent blood sugar spikes.
• Improves insulin sensitivity: Fenugreek may help the body become more sensitive to insulin, meaning it can use insulin more effectively to control blood sugar.
• Reduces inflammation: Fenugreek has anti-inflammatory properties that may help reduce the body’s resistance to insulin, improving blood sugar control.

While the results of studies vary, many trials have found that fenugreek can help lower A1C. A 2024 meta-analysis reviewed 12 clinical trials with over 1,700 participants. The results showed that fenugreek was effective in lowering fasting blood sugar and improving A1C levels in people with type 2 diabetes.

However, some studies had mixed results, and more research is needed to fully understand how well fenugreek works for everyone.³

Added Benefits for Diabetics

In addition to its benefits for blood sugar control and improving A1C levels, fenugreek can benefit people with diabetes in many other ways.

Evidence suggests it may:⁴

• Reduce inflammation: Flavonoids and saponins in fenugreek help reduce inflammation, which can lead to complications like heart disease, nerve damage, and kidney problems in people with uncontrolled blood sugar.
• Support heart health: Fenugreek seeds contain galactomannans and phytosterols, which have been shown to reduce cholesterol levels. Managing cholesterol is important for diabetics to prevent heart disease.
• Help manage weight: Fenugreek seeds are high in fiber and protein, which can help control weight by making you feel full and reducing fat absorption. Their appetite-suppressing properties help control hunger and reduce food intake. The seeds also promote calorie-burning processes.⁵
• Improve digestion: The fiber in fenugreek can reduce chronic constipation—a common diabetes complication—and help with overall digestion and bowel movement regularity.
• Reduce the risk of diabetic neuropathy: Some studies suggest bioactive compounds in fenugreek, especially the flavonoid isovitexin, may help protect nerves from damage caused by high blood sugar.⁶
• Support kidney health: Fenugreek may help prevent kidney damage, a common complication of long-term diabetes.
• Reduce oxidative stress: Its antioxidant properties may help reduce the damage caused by free radicals in the body, lowering the risk of complications like diabetic retinopathy.
• Prevent cognitive decline: The neuroprotective properties of isovitexin could help prevent cognitive decline, a common concern in diabetics, especially those with prolonged high blood sugar.⁶

How Much Fenugreek Should I Take?

Fenugreek can be taken in various forms, and the recommended dosage depends on the type you use.

Common suggestions include:

• Fenugreek seeds: 1 to 2 tablespoons (5–10 grams) per day, taken with water or in food.
• Fenugreek powder: 1 to 2 teaspoons (3–6 grams) per day.
• Fenugreek supplements: 500 milligrams to 1,000 milligrams per day, depending on the concentration of active compounds.

As always, when deciding how much fenugreek to take, it’s best to follow the product’s instructions or consult with a healthcare provider for personalized guidance.

When Does Fenugreek Start Working?

Fenugreek may begin to show effects on blood sugar and A1C levels within 10 days to three months of consistent use, depending on your individual condition and dosage.¹

Research indicates that taking fenugreek consistently, especially in the form of seeds or supplements, can help lower blood sugar and improve A1C over time.

However, the exact timeline can vary, so it’s important to monitor your progress and routinely check in with a healthcare provider.

Possible Side Effects

Fenugreek can lower blood sugar, but if you’re already taking medications like insulin, metformin, glipizide, or glyburide, it can lower your blood sugar too much (hypoglycemia). This can result in dizziness, confusion, or fainting.

To avoid these risks, talk to your doctor before using fenugreek, especially if you’re on diabetes medication.

Other possible side effects associated with fenugreek include:

• Digestive issues: Diarrhea, bloating, gas, and stomach upset are common.
• Allergic reactions: People with allergies to legumes (like peanuts or soybeans) may experience allergic symptoms such as rash, swelling, or difficulty breathing.
• Unusual body odor: Some people report a maple syrup-like smell in their sweat and urine after consuming fenugreek.
• Interference with medications: Fenugreek may interact with blood-thinning medications or affect hormone-sensitive conditions.

It’s best to consult a healthcare provider before using fenugreek, especially if you have pre-existing health conditions.

Who Shouldn’t Take Fenugreek?

Fenugreek is generally safe when eaten in foods, but taking it in larger amounts as a supplement can be risky, especially for children.

Fenugreek is a legume, like peanuts and soy, so people allergic to those foods may also be allergic to fenugreek.

Fenugreek has been linked to liver problems in some cases. People have reported liver toxicity, particularly when taking fenugreek alone or with other herbs, though these instances are rare.

Pregnant women should avoid taking fenugreek in amounts greater than what’s found in food, as it has been associated with birth defects. It’s unclear if it’s safe to use in larger amounts while breastfeeding.⁷

Fenugreek vs. Cinnamon for Diabetes

Both cinnamon and fenugreek have been studied for their possible benefits in helping manage diabetes, but they work in different ways.

• Cinnamon: Some studies suggest that cinnamon might help the body use insulin better and lower blood sugar levels, especially after meals. It could also help reduce fasting blood sugar, but not all research agrees on how well it works long-term.⁸
• Fenugreek: Fenugreek contains fiber that can slow down how quickly sugar is absorbed after eating. It may help lower A1C levels, which measure average blood sugar over a few months. Fenugreek may also help lower cholesterol, which is often a concern for people with diabetes.

Although taking cinnamon and fenugreek together might seem like a good way to lower blood sugar, this is not advised.

Both cinnamon and fenugreek have the potential to reduce blood sugar levels, and when combined, they could increase the risk of low blood sugar (hypoglycemia), especially for people taking diabetes medications.

Though there’s no strong evidence of a negative interaction between the two, their combined effects on blood sugar could be stronger than expected. Anyone considering using them together should talk to a healthcare provider to ensure it’s safe and monitor blood sugar levels closely.

Summary

Fenugreek may help manage blood sugar by improving insulin sensitivity and helping cells take in glucose. It can also slow down digestion, keeping blood sugar levels more stable. Taking about 10 grams of powdered fenugreek seeds daily can lead to improvements in blood sugar levels within 10 to 30 days.

While fenugreek has many health benefits, it’s important to use it with caution. It may cause digestive issues, allergic reactions, or interfere with medications. Pregnant women, children, and people with liver or diabetes issues should consult a healthcare provider before using fenugreek as a supplement.
