Like vitamins, minerals are micronutrients, which are substances required in small amounts that are nevertheless vital for normal growth, body function and health. While taking a multivitamin can ensure that you get the proper amount of minerals you need to stay healthy, untreated mineral deficiencies that persist for extended periods of time can cause serious health problems, such as osteoporosis and blood disorders.
The main sources of minerals, such as calcium and phosphorus, are food and dietary supplements. A healthy diet should provide all the vitamins and minerals needed for health without the need for supplements.
However, eating a diet that contains all necessary nutrients is often difficult, especially as current agricultural techniques have resulted in less nutritional fruits and vegetables. Although our bodies can more easily absorb minerals when they come with food compounds, mineral supplements are also effective.
As a general rule, mineral supplements are only required for people whose diets lack these essential substances. For example, older individuals may find it difficult to eat enough to get required amounts of minerals, and younger people's careers and families may make healthy eating difficult. Supplements may also be required to counteract the effects of certain health problems, including:
Similarly, certain health conditions can require that you get more or less of particular minerals. For example, pregnant women need to ingest enough minerals and vitamins to ensure the healthy development of the growing fetus. If a pregnant woman suffers from mineral deficiencies, serious pregnancy complications and birth defects may occur. Doctors may prescribe supplements during pregnancy, but a pregnant woman should not take extra vitamins and minerals without first consulting with her doctor.
Macrominerals are minerals required in large amounts by the body. Common macrominerals include:
Trace minerals are only required in tiny amounts, but are nevertheless vital for health. Trace minerals include:
