The Food and Drug Administration (FDA) does not approve dietary supplements, but it does have a role in regulating them. The approval and regulation of dietary supplements is a complex issue, and the FDA does not have to approve supplements before they hit the market. However, it's important to take precautions when selecting the right supplement for you. Multivitamins, vitamin D, echinacea and fish oil are among the many dietary supplements available. The FDA defines dietary supplements as vitamins, minerals, or other substances intended to supplement health and well-being.
An NDI is an ingredient, such as a vitamin, mineral, or probiotic, that has not been present in the food supply as an item used as food or in another dietary supplement.
Vitaminscan improve health, but not all vitamins and minerals are created equal. It's important to be aware of potential interactions between vitamins and other medications. For example, you shouldn't take vitamin E when taking blood thinners because this could thin your blood too much and cause internal bleeding. Calcium and vitamin D can help strengthen bones, and fiber can help maintain bowel regularity. The FDA does not determine if vitamins and other supplements are truly effective; it is the manufacturers who must ensure that their products are safe and that the claims they print on their labels are accurate.
What You Should Know Before Taking VitaminsWhen considering taking a vitamin or supplement, it's important to do your research.
Talk to your doctor about any potential risks or interactions with other medications you may be taking. It's also important to read labels carefully to make sure you're getting the right dosage for your age and health needs. It's also important to be aware of potential side effects of certain vitamins. For example, too much vitamin A can cause nausea, vomiting, headaches, and even liver damage. Too much vitamin D can cause kidney stones or calcium deposits in the body.
Too much iron can lead to constipation or even organ damage.
