Dietary supplements contain vitamins, minerals, herbs or other botanicals, amino acids, enzymes, and many other ingredients. Popular supplements include vitamins D and B12; minerals like calcium and iron; herbs such as echinacea and garlic; and products like glucosamine, probiotics, and fish oils.

Some dietary supplements can help you get adequate amounts of essential nutrients and also can improve overall health and help manage some health conditions.

Consult your healthcare providers (including doctors, dentists, pharmacists, and dietitians) as they can help you determine which supplements, if any, might be valuable for you.
