The importance of vitamins within the human body

The importance of vitamins within the human body, and virtually every bodily function that occurs cannot be overstated. For instance, vitamins provide metabolism for normal growth.

Top 10 Essential Vitamins and Minerals Your Body Needs

Vitamins and minerals are considered essential nutrients—because acting in concert, they perform hundreds of roles in the body. They help shore up bones, heal wounds, and bolster your immune system. They also convert food into energy, and repair cellular damage.

The formation of bones and tissues, and protect against viruses and disease. Vitamins also assist in the formation of hormones, blood cells, and countless chemicals within the human body.

Vitamins are also necessary for metabolism and create metabolically active enzymes which are required for numerous bodily functions to occur.

Vitamins are classified within one of two following categories: water-soluble or fat-soluble. There are thirteen primary vitamins, four that are fat-soluble and nine that are water-soluble. Water-soluble vitamins dissolve easily in water, and are readily removed from the body.

Since water-soluble vitamins are not stored within the human body, daily intake of foods containing the various vitamins is required.

Vitamins that are fat-soluble are absorbed through the intestinal tract with the help of lipids (fats).

Since fat-soluble vitamins are absorbed within the body, they have a higher probability of causing hypervitaminosis (a condition of high storage levels of vitamins, which can lead to toxic symptoms) than do water-soluble vitamins. Therefore, it is imperative that each individual monitor their intake of all vitamins and nutritional supplements.

  • Pyridoxine also supports the immune system through antibodies synthesis and helps regulate sodium and potassium levels within the body.

7.Vitamin B7

Vitamin B7

  • Biotin primary role is to promote the metabolic processing of carbohydrates, proteins and fats.
  • Biotin is required to create fatty acids and amino acids and assists in red blood cell synthesis.
  • Biotin also promotes healthy hair, skin and nails.

8.Vitamin B9

Vitamin B9

  • Folic acid is essential in the synthesis of ribonucleic (RNA) and deoxyribonucleic (DNA) acids.
  • Folic acid also contributes to the growth and development of the body, particularly in the division of nerve cells and transmitters.

9.Vitamin B12

Vitamin B12

  • Cyanocobalamin promotes the synthesis of red blood cells and the enzyme processes required to convert carbohydrates, proteins, and fats into energy.
  • Cyanocobalamin supports the central and peripheral nervous systems.

10.Vitamin C

Vitamin C

As a water soluble vitamin, C is one of the few nutrients where therapeutic macro-doses do not have severely adverse affects. This also means that it can be used as a therapeutic intervention in cases of systemic infection or slow healing, while regular supplementation can have further positive results.

The Importance of Vitamins and Minerals | SiOWfa15: Science in Our World:  Certainty and Controversy


Roughly 99 percent of calcium in the body is found in bones and teeth, where it is crucial for structural support. The remainder is found in the blood, muscles and intracellular fluids, where it is a critical part of many metabolic, neurological and muscular functions. Postmenopausal women (who have an elevated risk of osteoporosis) and people who don’t consume dairy products (a primary source of calcium) are the mostly likely to require calcium supplements.

You can get calcium from dairy products (such as milk, cheese, and yogurt), fortified non-dairy milks (such as almond, soy and rice milks), fortified orange juice, sardines with bones, tofu (if prepared with calcium), collard green, kale, and broccoli.


Iron is an essential part of building red blood cells, specifically hemoglobin, a protein  that bonds with oxygen to oxygen through the blood from the lungs to the cells throughout your body. Vegetarians need to consume almost twice as much iron daily because the iron in plant-based food is less available to the body than the iron found in animal products. Pregnant women and people with iron-deficient anemia may also need supplements.

You can get iron from meat (especially red meat and liver), seafood, lentils, beans, tofu, cashews, and broccoli.


Magnesium plays an important role in the function of more than 300 enzymes that regulate various processes in the body, including muscle and nerve function, heart rhythms and glucose control. Older adults and people with diabetes may need supplements.

You can get magnesium from almonds, spinach, cashews, peanuts, beans, potatoes, brown rice, dairy products, oats, chicken, beef and broccoli.


Zinc is a mineral that plays an important role in immune function and is essential for normal growth and development during pregnancy and childhood. Vegetarians may also need supplements since the zinc found in plant-based foods is less available to the body than that found in meat and fish.

You can get zinc from red meat, poultry, seafood (especially oysters, lobster and clams), dairy products, whole grains, beans and nuts.

Reach out to your pharmacist to get more information on supplements. Some vitamins (such as vitamin E) are dangerous in high doses, and some may interact negatively with other medications or medical treatment.
