The FDA doesn't test supplements for quality. So look for supplements that have been independently tested for quality. These will have a seal of approval from one or more of these:
- U.S. Pharmacopeia
- ConsumerLab.com
- NSF International
These seals don't guarantee that a product is safe or effective. But they do guarantee that it has the ingredients listed on the label. They make sure that it doesn't have contaminants.
If you take supplements, make sure to:
- Read the labels closely. See what vitamins and minerals it contains.
- Make sure the product doesn't expire soon.
- Store supplements in a cool, dry place. Make sure they are not in the sun or heat.
- Take certain supplements with food or at bedtime. This is to help prevent nausea.
- Keep a complete record of any dietary supplements and medicines you take. For each product, note the name, manufacturer, the dose you take, how often you take it, and the reason for use. You can share this record with your health care providers.
- Talk with your doctor about any supplements you take if you are scheduled to have any type of surgical procedure.
