Multiple vitamin-mineral (MVM) supplements contain a variable number of essential and/or non-essential nutrients. Their primary purpose is to provide a convenient way to take a variety of supplemental nutrients from a single product, in order to prevent vitamin or mineral deficiencies, as well as to achieve higher intakes of nutrients believed to be of benefit above typical dietary levels.
Many MVMs contain at least 100% of the Daily Value (DV) or the U.S. Recommended Dietary Allowance (USRDA) of all vitamins that have been assigned these recommended values. Mineral levels may be lower, or in the case of high potency MVMs, most or all mineral levels may also be at 100% of DV or USRDA.
Some nutrients may be beneficial at levels above what is possible to obtain from diet alone, and an MVM formula can provide these levels as well. Nutrients that may be useful to most people in larger amounts include vitamin C, folic acid, and calcium. Large amounts of vitamin B1, vitamin B2, vitamin B3, and pantothenic acid are often included in MVM formulas. Some people will experience improvements in mood, energy, and/or overall well-being when taking higher-than-RDA amounts of B vitamins.
