Vitamins and dietary supplements are substances you take to add nutrients to your diet or to lower your risk of health problems. Supplements can include vitamins, minerals, herbs, and other products in the form of pills, capsules, tablets, or liquids. While they can support your health, it's important to remember that they are not a replacement for a balanced diet. Consulting with a healthcare professional can help you determine which supplements, if any, are right for you.

FAQ
Are supplements regulated?
Supplements are regulated by the FDA, but less strictly than drugs.
Can supplements replace food?
No, supplements should complement, not replace, a healthy diet.
What are common vitamin deficiencies?
Deficiencies in iron, vitamin A, and iodine are the most common globally. But Americans may have lower-than-recommended levels of vitamin D, B12, calcium, and iron.
Are all supplements safe?
Not necessarily. Some can interact with medications or have side effects. While supplements are regulated to a degree, the FDA isn't authorized to approve dietary supplements for safety and effectiveness before they're marketed.
When should I take supplements?
Talk with your doctor if you think you may benefit from taking a supplement. For dosing instructions, follow the product label or your doctor's advice.
