Vitamins and minerals are essential nutrients because they perform hundreds of roles in the body.
Eating a healthy diet remains the best way to get sufficient amounts of the vitamins and minerals you need. Vitamins and minerals are considered essential nutrients—because acting in concert, they perform hundreds of roles in the body. Vitamins and minerals are often called micronutrients because your body needs only tiny amounts of them. Although they are all considered micronutrients, vitamins and minerals differ in basic ways. Because much of your body consists of water, many of the water-soluble vitamins circulate easily in your body.
Although water-soluble vitamins have many tasks in the body, one of the most important is helping to free the energy found in the food you eat.
Contrary to popular belief, some water-soluble vitamins can stay in the body for long periods of time.
Rather than slipping easily into the bloodstream like most water-soluble vitamins, fat-soluble vitamins gain entry to the blood via lymph channels in the intestinal wall (see illustration). Upon absorption, the fat-soluble vitamins enter the lymph vessels before making their way into the bloodstream. These vitamins are used throughout the body, but excesses are stored in the liver and fat tissues. As additional amounts of these vitamins are needed, your body taps into the reserves, releasing them into the bloodstream from the liver.
Together this vitamin quartet helps keep your eyes, skin, lungs, gastrointestinal tract, and nervous system in good repair.

Because fat-soluble vitamins are stored in your body for long periods, toxic levels can build up.
These include at least 30 vitamins, minerals, and dietary components that your body needs but cannot manufacture on its own in sufficient amounts.
A deficiency in vitamin D can cause rickets, a condition marked by soft, weak bones that can lead to skeletal deformities such as bowed legs. A combination of calcium, vitamin D, vitamin K, magnesium, and phosphorus protects your bones against fractures. Vitamin D enables your body to pluck calcium from food sources passing through your digestive tract rather than harvesting it from your bones. For example, vitamin C blocks your body’s ability to assimilate the essential mineral copper. Your kidneys continuously regulate levels of water-soluble vitamins, shunting excesses out of the body in your urine.
Several B vitamins are key components of certain coenzymes (molecules that aid enzymes) that help release energy from food. Vitamins B6, B12, and folic acid metabolize amino acids (the building blocks of proteins) and help cells multiply. One of many roles played by vitamin C is to help make collagen, which knits together wounds, supports blood vessel walls, and forms a base for teeth and bones.
Many fat-soluble vitamins travel through the body only under escort by proteins that act as carriers. In most cases, fat-soluble vitamins must be coupled with a protein in order to travel through the body.
Within your body, fat tissues and the liver act as the main holding pens for these vitamins and release them as needed.

Vitamin E also acts as an antioxidant (a compound that helps protect the body against damage from unstable molecules). Potassium, for example, is quickly absorbed into the bloodstream, where it circulates freely and is excreted by the kidneys, much like a water-soluble vitamin. When a vitamin C or E molecule makes this sacrifice, it may allow a crucial protein, gene, or cell membrane to escape damage. One study that pooled results from 68 randomized trials with over 230,000 participants found that people who were given vitamin E, beta carotene, and vitamin A had a higher risk of death than those who took a placebo.
But it’s tougher to shuttle vitamins from food and other sources into your body because cooking, storage, and simple exposure to air can inactivate these more fragile compounds. This substance, which is produced in the liver, flows into the small intestine, where it breaks down fats.
Calcium is more like a fat-soluble vitamin because it requires a carrier for absorption and transport. The context is also important—in some settings, for example, vitamin C is an antioxidant, and in others it can be a pro-oxidant. There appeared to be no effect from vitamin C pills and a small reduction in mortality from selenium, but further research on these nutrients is needed.
