How can supplements help lower blood sugar?
Each ingredient has a unique mechanism that may help lower blood sugar levels which is why many products are offered on the market for blood sugar support. Supplements may include dietary fiber which can help to slow the absorption of sugars and prevent high peaks in glucose after a meal. This can help the body manage the carbohydrate load of the meal.
In addition, some supplements may help improve the body's sensitivity to insulin. Thus, when paired with diet and exercise, these supplements may help in the management of blood sugar levels.
What supplements lower blood sugar?
When selecting a supplement it is important to identify ingredients that have shown potential in reducing blood sugar levels. Below is a list of some ingredients that have been shown in small studies to lower blood sugar.
- Ceylon cinnamon. With less coumarin, this form of cinnamon provides a milder taste than cassia cinnamon and is the preferred option for people taking this supplement daily.
- Berberine. This natural plant product is a yellow, often bitter-tasting ingredient that may help with weight loss, blood sugar levels, and blood pressure.
- Chromium. This is an essential trace element that the body needs but is unable to produce, and it is thought to help enhance the effects of insulin which in turn may lower blood sugar levels.
- Vanadyl sulfate. This is a form of the trace element vanadium that may help increase insulin sensitivity and help manage blood sugar levels.
- Blueberry fruit extract. A powerful antioxidant, this concentrated blueberry extract may provide help by reducing insulin resistance and may help manage glucose levels.
- Beta-D-glucans. This compound is commonly found in the fruiting bodies of medicinal mushrooms and may improve glucose control when taken daily.
Although most studies are conducted on people with diabetes, the effect of using these supplements for general blood glucose support is not well established and may need a consultation with your physician.
Supplements vs. medications to lower blood sugar
Most supplements have limited evidence of their ability to lower blood sugar levels, whereas medications have been thoroughly studied in rigorous double-blind clinical studies that have proven their ability to lower blood sugar levels in diabetes. The studies available for the support of supplements are often shorter and utilize small groups of patients making it more difficult to fully endorse a supplement's ability to lower blood sugar levels.
Medications are FDA-regulated to ensure purity, dosage, and effectiveness, whereas supplements are not FDA-regulated. In addition, medications undergo testing to ensure their safe use and continue to undergo monitoring once they are approved for use. Supplements, on the other hand, may not have the same degree of safety studies.
Can blood sugar support supplements replace medication for diabetes?
Supplements that potentially lower blood sugar levels should never replace medications for diabetes unless directed by a doctor. In certain cases, patients are able to manage their blood sugar levels with the use of diet and exercise, and in these cases, supplements may help them achieve their blood sugar goals.
If supplements are used, your doctor can help direct the appropriate use and perform the necessary monitoring to ensure that blood sugar levels are being kept within acceptable ranges. Thus, have a discussion with your doctor before starting any supplement or attempting to stop any medication.
How to take blood sugar support supplements
When taking a blood sugar-lowering supplement, it is important to take it as recommended by the manufacturer. Taking more of a supplement than recommended can result in side effects. In addition to sticking to the recommendations, it is important to:
- Take oral capsules with a full glass of water to ensure they adequately pass through the esophagus.
- Mix powder supplements well and re-stir the liquid if slowly consumed to ensure it remains a mixture.
- Take blood sugar support supplements with meals.
- Store them in a cool, dry place when not taking them.
Can supplements also lower cholesterol levels?
Yes. Supplements can include a variety of ingredients that may lower blood sugar levels and cholesterol levels. In some cases, one ingredient may be able to help lower blood sugar levels as well as improve cholesterol levels. This may be beneficial in people who have both high cholesterol and are looking for ways to manage their blood glucose.
High cholesterol, high blood sugar levels, and high blood pressure are common in metabolic syndrome and are often targeted together to prevent complications. Obtaining adequate control of cholesterol and blood sugar levels can reduce the risk of cardiovascular complications such as narrowing of arteries, heart attacks, and strokes.
Berberine and alpha lipoic acid are examples of supplements that may help lower blood sugar and cholesterol levels.
Do blood sugar supplements have any side effects?
Yes. Even though supplements usually come from natural sources, when they are used in concentrated doses as in many supplements they can produce side effects, as well as drug interactions. In many studies, the side effect profile of the supplements discussed in this review was similar to that of placebo. The most common side effects include:
- Stomach upset
- Sleeping difficulties
Some supplements, especially when taken in excess, can cause liver injury, low platelet counts, and kidney injuries. Therefore, it is important to discuss starting a supplement with your doctor or pharmacist to help minimize side effects and drug interactions.
Are there any dietary restrictions while using supplements to lower blood sugar?
No. There are no specific dietary restrictions when taking blood sugar lowering supplements.
It is recommended that people with diabetes or prediabetes follow a diabetes diet. This is a healthy diet consisting of fruits, vegetables, and whole grains. Heart-healthy fish such as tuna and salmon should be incorporated to provide omega-3 fatty acids. Monounsaturated and polyunsaturated are preferred over saturated fats and can be found in nuts, avocados, and canola or olive oils.
Healthy meal choices in combination with low-sodium foods should make up the majority of a meal and the diet should include consistent meal times. A diabetes diet can help to manage blood sugar levels, as well as cholesterol levels.

What's the recommended dosage for blood sugar supplements?
Supplements aimed at lowering blood sugar levels can contain various ingredients based on the manufacturer's preferences. Thus, it is important to read the labeling and stick to the recommended dosage of each manufacturer. This will prevent taking too much of a supplement and reduce the risk of experiencing adverse effects.
How long does it take for supplements to help control blood sugar?
Adequate blood sugar control is performed using the Hgb A1c lab value. This provides an estimate of the average blood sugar level over the last three months. It can take three months to notice any improvements in your Hgb A1c. During daily testing, you may notice blood sugar reductions sooner.
Should I consult a doctor before taking blood sugar supplements?
Yes. It is important to discuss all supplements with your doctor before starting them. Supplements that lower blood sugar levels can cause one's blood sugar to drop too low, especially when also taking prescription medications for diabetes. Thus, starting a new supplement may require dosing adjustments of existing medications.
