Overview of Supplement Use Among U.S. Adults
Surveys indicate that approximately 75% of U.S. adults have used dietary supplements, with 58% reporting usage within the past 30 days. These supplements, which include vitamins, minerals, herbs, amino acids, and probiotics, are often marketed to fill nutrient gaps and support wellness. However, unlike prescription medications, dietary supplements are not FDA-approved prior to marketing, although the FDA does regulate them and can act against unsafe products.
Health Risks Associated with Specific Supplements
Experts caution that certain supplements can pose significant health risks for individuals with diabetes due to their potential effects on blood glucose levels or interactions with diabetes medications.
St. John’s Wort
St. John’s Wort, commonly used for mild to moderate depression, may interfere with diabetes medications, making them less effective and complicating blood sugar management, according to Dawn Menning, a registered dietitian.
Chromium
While chromium is marketed for improving blood sugar regulation, evidence supporting its efficacy is limited. Menning warns that combining chromium with insulin or oral diabetes medications may increase the risk of hypoglycemia, which can lead to dizziness and fainting.
Bitter Melon
Bitter melon is often taken to reduce blood sugar levels. However, it contains compounds that may mimic insulin, potentially increasing the risk of hypoglycemia when used alongside diabetes medications.
Niacin (Vitamin B3)
Niacin is sometimes used to manage cholesterol levels but can raise blood sugar levels in people with diabetes, increasing the risk of hyperglycemia. Michelle Routhenstein, a preventive cardiology dietitian, advises against high-dose niacin supplements due to their potential to complicate blood sugar control.
Ginseng
Asian ginseng is associated with energy and immune support but may lower blood sugar levels when combined with diabetes medications, creating a risk for those managing their diabetes.
?-Carotene
The American Diabetes Association advises against ?-carotene supplementation due to its association with increased lung cancer and cardiovascular mortality risk.
High-Dose Cinnamon
While cinnamon is often promoted for diabetes management, excessive consumption can lead to hypoglycemia and liver damage due to a compound called coumarin.
Aloe Vera
Oral aloe vera is marketed for diabetes management but may cause blood sugar levels to dip dangerously low when taken with diabetes medications.
Regulatory Concerns and Expert Recommendations
Experts express concern that the primary issue with most supplements is not direct harm but the lack of regulatory oversight, which can lead to inconsistent composition and quality. The American Diabetes Standards of Care state that without an underlying deficiency, there are no benefits from supplementation for individuals with diabetes. The American Association of Clinical Endocrinology also advises caution regarding unregulated supplements.
Experts recommend consulting a healthcare provider before starting any supplement to understand its potential effects on blood sugar levels and diabetes management.
