Why do you take a nutritional supplement?

FAQ
No, nutritional supplements aren’t necessary for everyone. A balanced diet that prioritizes whole, unprocessed foods can typically provide sufficient nutrients without the need for supplementation. Consult your physician to see if you need a specific supplement before making a purchase.
Some supplements can cause side effects or interact with other medications you currently take. What’s more, supplements are not fully regulated, which can make it difficult to determine whether a specific supplement would be safe or effective for your body.
Start by speaking with your healthcare provider to learn which supplements best suit your situation and which brands they recommend. When shopping for a supplement, look for seals from independent organizations that test these products for both quality and safety.
Many supplements, from protein powders to creatine, are designed to improve athletic performance, reduce injury risk, and enhance recovery. However, research confirming how well they work is similarly varied, and individual products have their own risks at various doses.
Calcium, vitamin D, vitamin B6, and vitamin B12 supplements are often recommended for adults over age 50. Speak with your doctor or a dietitian to explore which supplements may be most helpful for you.
