Some people should be especially cautious before starting supplements: older adults, pregnant or breastfeeding women, people with kidney disease, liver disease, diabetes, heart disease, high blood pressure, cancer, autoimmune disease, or anyone taking prescription medications.
People should also be careful with supplements bought online, “detox” formulas, weight-loss pills, bodybuilding products, and products promising fast results. Big promises often come with bigger risks.
How to Use Supplements More Safely
Use supplements only when there is a clear reason. Check the dose on the label, avoid taking several products with overlapping ingredients, and tell your doctor or pharmacist everything you take, including vitamins, herbs, teas, powders, and gummies.
Do not assume that more is better. With vitamins and minerals, the safe range matters. Too little can be harmful, but too much can also be harmful.
Final Thoughts
Vitamins and supplements can be helpful in the right situation, but they can also be risky when used carelessly. Vitamin A, vitamin D, niacin, vitamin C, iron, green tea extract, kava, comfrey, and turmeric or curcumin supplements are all examples of products that deserve caution, especially in high doses or when combined with medications.
The safest rule is simple: before taking a supplement every day, especially at high doses, ask a healthcare professional if it is truly needed and safe for you.
