Key Takeaways
- There are no over-the-counter diabetes medications, though many dietary supplements are advertised to help treat diabetes.
- Certain dietary supplements may yield minor improvements in blood sugar levels, A1c, and insulin resistance, but high-quality data is lacking.
- These supplements are not as effective as prescription diabetes medications and should not be used as a substitute for medical care.
If you have type 2 diabetes, you may wonder if there are over-the-counter medications you can take to manage your blood sugar levels instead of common prescription medications like Metformin.
While this isn’t the case, there are over-the-counter (OTC) supplements advertised to people with diabetes.
Many of these aren’t proven to be effective, and some may interact with other medications you take.

Are there Over-the-Counter Diabetes Medicines?
Medications used to treat type 2 diabetes, such as Metformin, Ozempic, and insulin, require a prescription and cannot be purchased over the counter.
Several dietary supplements touted for treating diabetes are available for purchase without a prescription.
There is some evidence that specific dietary supplements may benefit diabetes management. These include:
- Berberine.
- Chromium.
- Cinnamon.
- Alpha-lipoic acid.
However, according to the National Center for Complementary and Integrative Health, there isn’t enough research to show that these supplements have a significant impact on blood sugar levels and are safe for people with diabetes.
Is Over-the-counter Diabetes Medicine Safe?
The most important thing to remember when considering dietary supplements for diabetes is that they should never replace your prescribed diabetes medications.
While preliminary research shows that certain dietary supplements may slightly improve blood sugar levels, they’re not as effective as prescription medications for diabetes.
Taking these supplements instead of your medications may not regulate your blood sugar levels properly and could result in complications.
Safety and effectiveness vary significantly across different dietary supplements for type 2 diabetes.
Some over-the-counter products, like cinnamon, are considered safe in lower doses, while others, like chromium, can cause kidney and liver damage.
Potential Benefits
The possible benefits of over-the-counter supplements for type 2 diabetes depend on the specific product and may include:
- Reduced fasting blood sugar levels.
- Improved A1c.
- Less insulin resistance.
- Improved cholesterol panel.
- Lower blood pressure.
- Less diabetic neuropathy pain.
However, the research has yet to demonstrate that the benefits of dietary supplements are significant enough to recommend them as part of standard medical treatment for type 2 diabetes.
Risk and Side Effects
Digestive upset is a common side effect of diabetes supplements, which is more likely with high doses of a supplement. These can include:
- Heartburn.
- Stomach pain.
- Nausea.
- Vomiting.
- Diarrhea.
- Bloating,
- Constipation.
Dietary supplements can interact with each other and medications, causing side effects or making them less effective.
Certain supplements may not be safe to take with prescription diabetes medications and could cause blood sugars to become too high or too low.
Some dietary supplements have been linked with kidney disease, like chromium.
Because kidney disease is more common in people with diabetes, this is something to be very cautious of.
Additionally, some supplements, like berberine, are not safe to take while pregnant or breastfeeding.

Considerations for Taking OTC Diabetes Medicine or Supplements
If you’re interested in trying over-the-counter supplements for diabetes, it’s important to talk with your healthcare team about the risks and benefits, take the proper dosage, and monitor your blood sugar levels closely.
Consult Your Health Provider First
Before starting new supplements, talk with the doctor managing your diabetes care.
It’s unlikely you’ll be able to replace your prescription diabetes medication with over-the-counter supplements, but your healthcare provider may suggest specific supplements to take in addition to your current therapies.
Reviewing your medication and supplement list with your provider can help them screen for potential interactions and risks.
Your doctor may run lab work to check your vitamin and mineral levels.
Certain supplements, like vitamin B12 and vitamin D, may be recommended if you have deficiencies.
Choose High-Quality Supplements
The FDA doesn't regulate dietary supplements in the same way as prescription medications.
When shopping for products, select brands that undergo voluntary third-party quality testing, indicated by the following seals on the label:
- NSF.
- USP.
- ConsumerLab.
These certifications verify that the supplements contain the ingredients and dosages they claim to provide.
They also test for contaminants like heavy metals.
Keep in mind that third-party testing does not verify that a supplement is safe or effective for the advertised purpose.
Follow Dosage Instructions Carefully
Talk with your healthcare provider about the proper dosage of dietary supplements.
They may recommend something different than what the label on the bottle says.
Taking too much of certain supplements can cause digestive symptoms and, in some cases, serious kidney and liver damage.
Monitor Your Blood Sugar Levels Regularly
If you choose to start an over-the-counter supplement for diabetes, it’s important to keep track of your blood sugar levels to determine the impact (positive or negative) the product has on your diabetes management.
Reach out to your doctor if your blood sugar levels are routinely outside of the target ranges given to you.
Your doctor may want to discontinue the supplement or adjust one of your diabetes medications.
Other Diabetes Management Options
Making healthy dietary and lifestyle changes can help you manage your diabetes in addition to medication therapy and supplements.
Nutrition Changes
You can utilize the diabetes plate method to help balance your meals and support healthy blood sugar levels.
This involves filling ¼ of your plate with high-fiber carbohydrates, like brown rice or whole wheat pasta.
Next, include ¼ plate of lean protein, like chicken, salmon, or lentils.
The remaining half of the plate is for non-starchy vegetables, including spinach, zucchini, and cauliflower.
Try to reduce your intake of added sugars, like those found in desserts, juice, and soda.
Exercise
Regular physical activity can help manage blood sugar levels and has other health benefits like improved mood and sleep.
A good goal is to try for around 30 minutes of aerobic exercise five days per week.
This includes activities like walking, biking, and swimming. Including strength exercises, such as weight lifting or resistance bands, is also beneficial.
Takeaway
Most over-the-counter supplements for diabetes lack sufficient research to show they’re effective for managing blood sugar levels.
Importantly, they aren’t proven to be a safe or effective substitute for prescription diabetes medications.
Certain dietary supplements may have mild benefits in diabetes management, but they are not without risks.
Talk with your doctor before starting any supplements to assess the potential side effects and interactions with other medications.

Frequently Asked Questions
Several diabetes supplements, such as berberine, chromium, cinnamon, and alpha-lipoic acid, are available over the counter. However, evidence to support the effectiveness of these supplements for treating diabetes is lacking.
Talk with your doctor before starting any dietary supplements for diabetes management because some may have side effects and safety risks and can potentially interact with the medications you’re on.
Berberine is an over-the-counter supplement that may improve insulin resistance, similar to the action of Metformin, a common diabetes prescription medication. However, berberine has not been proven to be as effective as metformin. More research is needed to learn the effectiveness and long-term safety of this supplement.
It’s not recommended to attempt managing diabetes on your own without a doctor. Over-the-counter supplements have not been proven to be as effective as prescription diabetes medications. For many people, medication therapy is needed in addition to diet and lifestyle changes to manage blood sugar levels.
Even if your diabetes is managed through diet and lifestyle habits, it’s still important to see your doctor routinely to monitor your blood sugar and A1c levels.
