What are supplements for vitamin deficiency?

Supplements for vitamin deficiency contain high amounts of individual vitamins or combinations of vitamins. They treat vitamin deficiency when blood levels are below normal because of a dietary deficiency, malabsorption, or disease. These supplements include vitamin D, vitamin B12, folate, vitamin C, B‑complex vitamins, vitamin A, vitamin K, and multivitamins with minerals.

Should I choose a multivitamin or an individual vitamin and mineral?

A multivitamin can be a good option if you want support for several areas of your diet. A single nutrient may be better if you have a specific need. However, a multivitamin may not contain enough of a nutrient to correct a confirmed deficiency.

How do I know whether I have a nutrient deficiency?

You usually can’t know for sure based only on how you feel. The reliable way is to see a clinician, describe your diet and symptoms, and get blood tests that check specific nutrients. They will also consider your health conditions to decide if you truly have a deficiency and whether you need supplements or just diet changes.

Can supplements replace a balanced diet?

No. While supplements can fill nutritional gaps, they cannot replace a balanced diet of whole foods, which contain fiber and many other nutrients and beneficial compounds not found in supplements. Take your supplements with meals, not in place of them.
