Multivitamins may contain a short or long list of ingredients. A number of vitamins from the B-complex family are likely to be found on the list. Other vitamins that are common include A, C, and K. Minerals are also common multivitamin ingredients. Examples include iron, zinc, and copper.
There is not generally a number of ingredients that is considered standard for multivitamins. The content of these supplements tends to vary based on the preferences of the manufacturer and the purpose for which the multivitamins are marketed. Many of these supplements are formulated for special groups, such as women, active men, or seniors. As such, some formulations only have about a dozen different ingredients, while others may have more than two dozen.
Vitamin A is one of the common multivitamin ingredients that is often a subject of concern. Taking too much vitamin A is believed to increase the risk of birth defects and liver damage, and it may result in bone softening. Some studies have found that many supplements contain more vitamin A than is recommended for the groups toward whom the products are marketed.
Folic acid, also known as B9, is a common ingredient in multivitamins. This nutrient is important for the health of human cells, but it is often difficult to obtain the recommended amount through regular dietary consumption. Men, however, should be cautious about the amount of folic acid that they consume because a connection has been made between excessive amounts and prostate cancer.
Another of the common multivitamin ingredients that belongs to the B-complex family is riboflavin, also known as B2. Riboflavin is believed to benefit the body in numerous ways, such as helping to prevent disease and warding off conditions that result from a deficiency of the nutrient, such as eye problems and ulcers. One reason why it is commonly included among multivitamin ingredients is because it is sensitive and may be damaged during the storage or preparation of foods.
Iron is one of the minerals that is often listed among the multivitamin ingredients. This mineral is utilized by the body for a number of things, including keeping the blood healthy and playing a role in the production of neurotransmitters. The inclusion of iron in supplements is also a subject of dispute because excessive amounts pose serious threats, such as brain damage and heart attacks.
Among the list of multivitamin ingredients, a person is likely to find copper. This trace element is believed to have a number of benefits such as scavenging free radicals, helping to metabolize iron, and playing a role in maintaining the normal functioning of the central nervous system. It is believed that a copper deficiency can lead to osteoporosis and thyroid disorders.
