Sugar Blocker Supplements Exposed: Do They Really Help You Crush Cravings?

For individuals seeking to manage blood sugar levels and curb sugar cravings, the allure of sugar blocker supplements is undeniable. These supplements, often derived from natural sources, claim to help regulate blood glucose, improve insulin sensitivity, and ultimately reduce the desire for sugary foods. While the concept is promising, it's crucial to approach these supplements with a balanced perspective, considering both their potential benefits and limitations.

Understanding Sugar Cravings

Before diving into the world of supplements, it's essential to understand the underlying causes of sugar cravings. These cravings often stem from a combination of factors, including:

Blood Sugar Imbalances: Fluctuations in blood sugar levels can trigger intense cravings for quick sources of energy, leading to a desperate need for a sugar fix.
Emotional and Psychological Factors: Sugar cravings are often tied to mood and emotions, serving as a way to numb unpleasant feelings.
Gut Microbiome Imbalance: An imbalance in the gut microbiome, with an overgrowth of sugar-hungry bacteria, can increase cravings for sugary foods.

The Role of Supplements

Supplements can be a powerful tool to help curb sugar cravings when paired with diet and lifestyle changes. They may provide extra support to balance hormones, regulate blood sugar, and promote a healthy gut microbiome. However, it's crucial to remember that supplements should never replace medications used to treat prediabetes and diabetes.

10 Supplements That May Help Lower Blood Sugar

Here are ten supplements that have shown potential in helping to lower blood sugar and manage sugar cravings:

Cinnamon: Cinnamon supplements, made from whole cinnamon powder or an extract, may help the body better respond to insulin, which in turn may help lower blood sugar and improve diabetes control. A 2019 review and meta-analysis of 18 studies showed that cinnamon did significantly reduce fasting blood sugar by an average of 19.26 mg/dL. However, the common Cassia variety of cinnamon contains coumarin, which may harm your liver if consumed in high amounts.

Ginseng: Ginseng is a flowering plant commonly found in North America. A 2024 review found that it may help to decrease post-meal blood sugar in healthy individuals and those with type 2 diabetes. However, ginseng should be avoided if you are taking immunosuppressant drugs or blood thinners, like warfarin, as it can decrease the effectiveness of the medication.
Probiotics: Probiotic supplements contain beneficial bacteria or other microbes that offer numerous health benefits and may improve your body’s handling of carbohydrates. By promoting a healthy gut microbiome, probiotics can help keep sugar-craving bacteria in check. Probiotics are unlikely to cause harm, but in certain rare circumstances, they could lead to infections in people with significantly impaired immune systems.
Aloe Vera: Supplements or juice made from the leaves of this cactus-like plant could help lower fasting blood sugar in people with prediabetes or type 2 diabetes. However, aloe can interact with several medications, such as the heart medication digoxin, which is why it’s important to check with a doctor before use.
Berberine: Berberine is a bitter-tasting compound taken from the roots and stems of certain plants, including goldenseal and Phellodendron. A 2021 review and meta-analysis found that berberine could help reduce fasting blood sugar without the risk of hypoglycemia. However, berberine may cause digestive disturbances, such as constipation, diarrhea, or gas. It may also interact with some medications, so check with a doctor before taking this supplement.
Vitamin D: Increasing your intake of vitamin D may improve the function of pancreatic cells that make insulin and increase your body’s responsiveness to insulin. Studies have suggested that vitamin D supplementation may confer a positive effect on glycemic control. One 2017 review and meta-analysis of 29 trials including 3324 participants found a modest reduction in A1c (decreased by 0.32% on average). Vitamin D may trigger mild to moderate reactions with several types of medications. A doctor or pharmacist can provide guidance on whether a supplement is safe for you to take.

Gymnema Sylvestre: Gymnema Sylvestre is an herb used as a diabetes treatment in the Ayurvedic tradition of India. Studies have found that it may reduce sugar absorption in your gut and significantly reduce fasting blood glucose by 1.57 milligrams per decilitre. This herb can enhance the blood sugar effects of insulin, so only use it only with a doctor’s guidance if you take insulin injections.
Magnesium: Low blood levels of magnesium are common in people with type 2 diabetes and are more common in those who don’t have their blood sugar under good control. Taking magnesium supplements may help to promote healthy insulin production and insulin action in your body’s tissues. A 2017 review and meta-analysis concluded that magnesium supplementation can lead to improved FBG, HDL, LDL, triglycerides, and systolic blood pressure in people diagnosed with diabetes, suggesting it may be beneficial in mitigating cardiovascular disease associated with diabetes. Magnesium supplements may interact with several medications, such as diuretics and antibiotics. Before beginning magnesium supplements, consider checking with a doctor or pharmacist for any potential drug interactions.
Alpha-Lipoic Acid (ALA): Alpha-lipoic acid, or ALA, is a vitamin-like compound and powerful antioxidant produced in your liver and found in some foods, such as spinach, broccoli, and red meat. Taking ALA supplements alongside prescription diabetes treatment may help decrease fasting blood sugar and A1C, though it may take a few months to experience these effects. It may also protect against oxidative damage caused by high blood sugar. ALA may interfere with therapies for hyperthyroid or hypothyroid disease. Avoid very large doses of ALA if you have vitamin B1 (thiamine) deficiency or live with an alcohol use disorder.
Chromium: Chromium deficiency reduces your body’s ability to use carbs - converted into sugar - for energy and raises your insulin needs. This means chromium supplements may enhance the effects of insulin or support the activity of pancreatic cells that produce insulin. Certain drugs - such as antacids and others prescribed for heartburn - can reduce chromium absorption. A healthcare professional can provide guidance on any potential drug interactions.

Additional Supplements to Consider

Beyond the ten supplements listed above, other options may also contribute to blood sugar management and craving control:

Inositol: Inositol is a sugar the body produces to support your cells. It is essential for healthy metabolism, your body's response to insulin, blood sugar regulation, and serotonin production.
Prebiotics: Prebiotics are essentially food that feeds the good bacteria in your gut, promoting a healthy and balanced microbiome.
Adaptogens: Adaptogens are a group of herbs used for centuries to reduce the body’s response to stress, which can indirectly help regulate blood sugar and cravings.
Zinc: Zinc plays a key role in the production and secretion of insulin.
Folate: Folate supplementation is one way of lowering homocysteine, which is associated with higher insulin resistance and risk of type 2 diabetes.
PUFAs: There has been much attention given to the role PUFAs play in the prevention and treatment of diseases related to inflammation.
Dietary Fiber: The ADA recommends a goal of 25-35 gm of dietary fiber daily for a healthy diet. Table 1. 4-40 g fiber daily.

Important Considerations

While supplements can be a valuable tool, it's crucial to approach them with caution and awareness:

Individual Results May Vary: Remember that you may experience different results than what studies have found based on factors such as duration, supplement quality, and your individual diabetes status.
Consult a Healthcare Professional: Before beginning any supplement, consider checking with a doctor or pharmacist for any potential drug interactions. This is especially important if you have underlying health conditions or are taking medications.
Dosage and Interactions: In most cases, dosage instructions and potential drug interactions will be listed on the supplement packaging. However, if you’re unsure of how much you should take, a healthcare professional can help.
Supplements Are Not a Replacement for Medication: Though supplements should never replace medications used to treat prediabetes and diabetes, some may provide beneficial effects when used alongside medications.
Quality and Regulation: Supplements are not regulated with the same degree of oversight as medications, and it is important that clinicians keep this in mind.
Combining Supplements: Combining supplements for blood sugar regulation can be dangerous because blood sugars can dip too low, putting you in a hypoglycemic state.

Lifestyle and Dietary Changes

As a functional medicine dietitian, it's important to remember that food and lifestyle adjustments are the foundation for good health. Here are some additional ways to manage cravings besides supplements:

Focus on a balanced diet: Prioritize whole, unprocessed foods, including plenty of fruits, vegetables, lean protein, and healthy fats.
Manage stress levels: Practice stress-reducing techniques such as yoga, meditation, or spending time in nature.
Get enough sleep: Aim for 7-8 hours of quality sleep per night to regulate hormones and reduce cravings.
Stay hydrated: Drink plenty of water throughout the day to help regulate blood sugar and reduce cravings.
Consider a hormone-balancing lifestyle: A healthy, hormone-balancing lifestyle is your best defense against sugar cravings.
