Dietary Supplements That Can Interact With Your Diabetes Medications

Watch your blood glucose more closely to verify the effect of these supplements.

1. Niacin - is found in many foods, such as beef, chicken, and marinara sauce. It's available as both a prescription medication and supplement to help lower cholesterol. But niacin and diabetes may not be the best mix.
Some studies have found that high doses of niacin (1,500 mg per day or more) can raise your blood glucose.

The dose of niacin in a multivitamin is unlikely to lead to a noticeable change in your blood glucose levels.

2. St. John's wort - an herbal product that's marketed to help improve mood.  It's notorious for interacting with medications. In most cases, it makes them leave your body too quickly, lowering medication effectiveness. But St. John's wort can amplify the effects of some medications, too.
There haven't been many studies that look into how St. John's wort affects diabetes medications. But it may make sulfonylureas like glipizide, thiazolidinediones like Actos (pioglitazone), and dipeptidyl peptidase-4 (DPP-4) inhibitors like Januvia (sitagliptin) less effective.
Another study found that St. John's wort can raise the level of metformin in your body. This can lower your blood glucose by raising the amount of insulin released by your body.

3. Ginseng - a plant that's been used for thousands of years in medicine.
Newer research also suggests that ginseng may lower fasting blood glucose and hemoglobin A1C in people with Type 2 diabetes. It's thought that ginseng does this by telling your body to make more insulin and remove glucose from the blood.
If you start taking ginseng with diabetes medications, you may want to watch your blood glucose more closely.
Good to know: Many types of ginseng are available, the most popular ones being Asian and American ginseng. They might not all have the same effect on blood glucose.

4. Aloe vera - a plant that's well-known for relieving the symptoms of conditions like sunburn. But aloe vera also comes in oral forms...
Topical aloe vera isn't a concern for diabetes interactions, but oral aloe vera may impact your blood glucose. Some studies found that it might lower fasting blood glucose in people with prediabetes. It may also lower A1C for people who already have diabetes.

5. Ginkgo biloba - One study found that ginkgo biloba can raise blood glucose levels in people who take oral diabetes medications. It's not exactly clear why this happens, but researchers think it causes your liver to break down insulin faster. To be safe, keep an eye out for high blood glucose symptoms and monitor your blood glucose more frequently after starting ginkgo biloba.
On the other hand, some interactions may be positive. Another study looked at taking ginkgo biloba with metformin. It found that ginkgo biloba helped improve blood glucose for people who didn't see much improvement from metformin alone.

6. Ginger - has been used for thousands of years to flavor food, but people also use it to treat certain ailments, such as nausea and menstrual cramps.
It's not fully clear if ginger interacts with diabetes medications, but some studies suggest that it can lower both your blood glucose and A1C. Other studies show it doesn't affect fasting blood glucose, but it can lower your A1C.

7. Vitamin E - an essential vitamin that is found in a variety of foods, such as nuts, broccoli, and tomatoes. Vitamin E may help improve heart, eye, and brain health when eaten as part of a balanced diet.
High doses may increase your risk for certain problems, including stroke and prostate cancer. On the other hand, some studies say that vitamin E is helpful for people living with diabetes. It may help lower fasting blood glucose levels in the short term.

8. Chromium - a mineral that's found naturally in many foods, such as fruit juice, certain meats, and lettuce. It may play a role in helping the body break down food for energy.
Chromium supplements may help improve your body's response to insulin, but more research is needed. What's more, it may also lower fasting blood glucose levels for people living with diabetes.

9. Green tea extract - It's been reported to potentially support lower blood pressure, improved digestion, and kidney stone prevention. Studies suggest that green tea may also slightly lower the risk of diabetes.
As a supplement, green tea extract may improve inflammation and skin quality. What's more, it may lower A1C and fasting blood glucose levels.
