Natural remedies for diabetes: Do herbs really help blood sugar?

Managing diabetes often means keeping a close eye on blood sugar, making healthy food choices, staying active and taking medications as prescribed. But have you wondered if herbs or natural supplements can help, too? 

From cinnamon to bitter melon, the internet is full of claims about “blood sugar–lowering” herbs. Let’s take a closer look at what research really says and what you should keep in mind. 

Cinnamon

This popular spice has been studied for its potential effects on blood sugar. Some studies suggest it may help improve insulin sensitivity or slightly lower fasting blood glucose. However, results are mixed, and the effects are generally modest. Cinnamon can be a tasty addition to your diet, but its effects on blood sugar are inconclusive.

Ginger

Ginger contains a natural compound called gingerol, known for its strong anti-inflammatory and antioxidant effects. These properties may help your body use glucose more effectively and support healthier blood sugar levels.

In people with Type 2 diabetes, gingerol may also play a role in supporting insulin function.

Green tea

Green tea is a popular beverage that may also support blood sugar management in people with Type 2 diabetes. Research suggests that it can help improve insulin function, reduce insulin resistance and support healthy blood lipid levels.

Bitter melon

Common in traditional medicine, bitter melon has compounds that may mimic insulin or help cells absorb glucose. Early research shows some promise, but studies are limited and often small. Like cinnamon, bitter melon should not replace prescribed treatments.

Turmeric

Turmeric is a spice that’s long been valued in traditional medicine, and research suggests it may also have benefits for people with prediabetes. Studies show that turmeric can help support insulin function, which is key for moving glucose from your blood into your cells so your body can use it for energy.

Safety first

“Natural” doesn’t always mean safe.  In the United States, herbal supplements aren’t regulated for safety or effectiveness by the U.S. Food and Drug Administration. 

Herbs can interact with diabetes medications, blood pressure medicines or blood thinners. Side effects are possible, and quality can vary between products. Always check with a healthcare professional before adding a new supplement.

Bottom line

Herbs may offer small benefits, but they are not a substitute for a balanced diet, regular exercise and medications prescribed by your healthcare team. They can, however, complement a healthy lifestyle when used safely and thoughtfully.
