Editing Multivitamin (section)

== Products and components ==
Many multivitamin ''formulas'' contain [[vitamin C]], [[Vitamin B1|B<sub>1</sub>]], [[Vitamin B2|B<sub>2</sub>]], [[Vitamin B3|B<sub>3</sub>]], [[Vitamin B5|B<sub>5</sub>]], [[Vitamin B6|B<sub>6</sub>]], [[Vitamin B7|B<sub>7</sub>]], [[Vitamin B9|B<sub>9</sub>]], [[Vitamin B12|B<sub>12</sub>]], [[Vitamin A|A]], [[Vitamin E|E]], [[Vitamin D2|D<sub>2</sub>]] (or [[Vitamin D3|D<sub>3</sub>]]), [[Vitamin K|K]], [[potassium]], [[iodine]], [[selenium]], [[borate]], [[zinc]], [[calcium]], [[magnesium]], [[manganese]], [[molybdenum]], [[beta carotene]], and/or [[iron]]. Multivitamins are typically available in a variety of formulas based on age and sex, or (as in prenatal vitamins) based on more specific nutritional needs; a multivitamin for men might include less iron, while a multivitamin for seniors might include extra vitamin D. Some formulas make a point of including extra [[antioxidants]].

Some nutrients, such as calcium and magnesium, are rarely included at 100% of the recommended allowance because the pill would become too large in size. Most multivitamins come in capsule form; tablets, powders, liquids, [[gummies]] and injectable formulations also exist. In the United States, the [[FDA]] requires any product marketed as a "multivitamin" to contain at least three vitamins and minerals; furthermore, the dosages must be below a "tolerable upper limit", and a multivitamin may not include herbs, hormones, or drugs.<ref>{{cite web |title=How to Choose the Right Vitamins and Minerals for Your Health Needs |url=https://medium.com/@seosince18/choose-the-right-vitamins-and-minerals-for-your-health-needs-6595d52ae92d |url-status=live |archive-url=https://web.archive.org/web/20250408113158/https://medium.com/@seosince18/choose-the-right-vitamins-and-minerals-for-your-health-needs-6595d52ae92d |archive-date=8 April 2025 |access-date=6 April 2025 |publisher=[[Medium (website)|Medium]]}}</ref>
