What Happens to Your Blood Sugar When You Take Ginger Supplements Regularly

From verywellhealth.com

Key Takeaways

• Ginger supplements may modestly lower fasting blood sugar in people with type 2 diabetes, but study results are mixed.

• Most research focuses on ginger powder or supplements, not ginger added to foods, for blood sugar control.
• Ginger supplements may interact with diabetes medications and cause blood sugar to drop too low, so consult a healthcare provider before use.

Ginger is a zesty spice commonly used in foods and beverages. Some research suggests that it may modestly improve blood sugar control in people with type 2 diabetes. However, most studies tested ginger powder or standalone supplements rather than ginger added to foods.

Fasting Blood Sugar Levels May Decrease

Fasting blood sugar measures the amount of glucose (sugar) in the blood after at least 8 hours without eating. Some research suggests that ginger supplements may lower fasting blood sugar in people with type 2 diabetes, but results are mixed.

One systematic review and meta-analysis found that people with type 2 diabetes who took 1.2 to 2 grams of ginger powder daily for 4 to 12 weeks had fasting blood sugar levels about 19 milligrams per decilitre (mg/dL) lower, on average, than those who did not.

However, a more recent review of five clinical trials found no significant overall reduction.

Insulin Sensitivity May Improve

Insulin is a hormone that helps move glucose from the bloodstream into cells for energy. With insulin resistance, the body doesn’t respond to insulin effectively, which can cause blood sugar to rise. Insulin resistance is common in people with metabolic syndrome and type 2 diabetes.

Some research suggests that ginger may improve insulin sensitivity. In one study, people with metabolic syndrome who took 2 grams of ginger powder daily for 12 weeks showed improvements in insulin sensitivity and fasting blood sugar.

A systematic review and meta-analysis also found that ginger supplementation may reduce insulin resistance in people with type 2 diabetes and metabolic syndrome.

A1C May Decrease Over Time

Haemoglobin A1C (HbA1C) reflects your average blood sugar levels over the previous 12 weeks. One meta-analysis of 13 studies found that ginger supplements lowered A1C by about 0.4 percentage points in people with type 2 diabetes. The researchers noted that such a small decrease may not significantly affect blood sugar control on its own.

Not all studies have found this benefit. A 2024 review of five clinical trials found no significant overall reduction in A1C. Differences in ginger doses, study length, and design may explain the conflicting results.

Dietary Ginger May Have Less Effect on Blood Sugar

Most research on ginger and blood sugar has involved ginger powder or supplements taken daily for several weeks. Studies of ginger consumed with food or drinks are limited and show conflicting results:

• Ginger water: In one small study, 24 adults without diabetes who consumed a preparation containing 0.2 grams of ginger powder after a glucose drink had a smaller rise in blood sugar and a lower peak blood sugar over the following two hours.
• Ginger with food: Another study of 12 healthy adults found that adding 3 or 6 grams of ginger to rice pudding did not reduce the rise in blood sugar after eating.

These studies suggest adding ginger to meals may not have a meaningful or predictable effect on blood sugar. There is not enough evidence to know whether regularly eating fresh or dried ginger can lower fasting blood sugar or A1C over time.

Ginger Supplements and Safety

Research showing potential blood sugar benefits has primarily involved ginger powder or supplements rather than ginger added to foods. Although supplements may improve blood sugar control in some people with type 2 diabetes, they should not replace diabetes medications or treatments.

Ginger supplements may increase the effects of insulin and other diabetes medications, possibly causing blood sugar to drop too low (hypoglycaemia). Talk to a healthcare provider before taking a ginger supplement while using these medications.

Ginger may also cause side effects, including:

• Heartburn
• Stomach discomfort
• Diarrhoea
• Mouth or throat irritation
