Are vitamins really that important? We can get vitamins from food so why do we have to take them in tablet form?

Vitamins are essential part in our health. Though we are able to get them from food, it is still not enough. That is why some people take vitamin supplements. For instance, a person who is not drinking milk or any other calcium containing product would most likely be calcium deficient. Here is where these supplements come into play.

We have 2 types of Vitamins the water soluble and fat soluble one: All you have to remember is the work 'ADEK'. Vitamins A, D, E, and K are fat soluble vitamins while the rest are water soluble.

Vitamin A

Vitamin A is needed for growth and normal development, maintenance and repair of tissues, maintenance of immune function, normal and night vision. It is found in the British diet in two forms:
1. Retinol (pre-formed vitamin A): found in meat and meat products, liver, kidney, milk and milk products derived from whole milk, margarine (fish liver oils).
2. Carotenoids (pro-vitamin A, e.g. β-carotene): found in all vegetables, especially carrots, and red and orange fruit (e.g. tomatoes). Take note: Not all carotenoids are precursors for vitamin A.

Vitamin B1

Thiamin, also known as, vitamin B1 is involved in the metabolism of fat, carbohydrate and alcohol. All cereals, especially breads and breakfast cereals, and potatoes are significant sources of this vitamin in the British diet. Smaller quantities are provided by a wide range of foods, including meat and meat products, milk and milk products, and vegetables.

Vitamin B2

Riboflavin, also known as, vitamin B2 is required for oxidative processes and there are a number of enzymes that are flavin dependent. Riboflavin is found in milk and milk products and fortified breakfast cereals, which are the main sources in the British diet. Meat and meat products provide smaller quantities.

Vitamin B3

Niacin (nicotinamide and nicotinic acid) or vitamin B3 is the reactive part of the coenzymes NAD and NADP, and so is very important in intermediary metabolism (e.g. energy production). Niacin requirement is related to energy metabolism. Meat and meat products, bread, fortified breakfast cereals, potatoes, milk and milk products are the main sources of niacin in the British diet (it is also provided by fish).

Vitamin B5

Pantothenic acid is needed for the release of energy from fats, carbohydrates, proteins and alcohol. Experimental deficiency has been found to result in fatigue, headaches, dizziness, muscle weakness and gastrointestinal problems. There is no evidence of deficiency in humans, except in experimental situations. Pantothenic acid is widely distributed in foods, in particular in animal products, wholegrains and legumes.

Vitamin B6

Vitamin B6 or pyridoxine is a cofactor for a large number of enzymes associated with amino acid metabolism. It is widely distributed in foods. Particular sources are potatoes and breakfast cereals. It is essential for energy production and red blood cell production.

Vitamin B7 or Vitamin H

Biotin deficiency is rare in humans and has occurred only as a result of bizarre dietary practices or in long-term parenteral nutrition. Deficiency results in scaly dermatitis and hair loss. This vitamin is widely distributed in foods and is synthesized by intestinal microorganisms.

Vitamin B9

Folic acid is a synthetic form of the B vitamin folate. The vitamin is involved in a number of single carbon transfer reactions, especially in the synthesis of purines, pyrimidines, glycine and methionine. Therefore, deficiency affects blood cell development and growth. Folates are found in: green leafy vegetables especially sprouts and spinach; green beans and peas; potatoes; fruit, especially oranges; Bovril and yeast extract; and milk and milk products. Folic acid is added to a number of products these days, especially some breakfast cereals and bread.

Vitamin B12

Vitamin B12, also called cobalamin, is involved in the recycling of folate coenzymes and is needed for nerve myelination. Vitamin B12 is found naturally only in foods of animal origin – meat and its products, especially liver, and milk and its products make the major contribution. It is also present in eggs and fish, and is added to fortified breakfast cereals.

Vitamin C

Vitamin C prevents scurvy and aids wound healing. It also assists in the absorption of non-haem iron and is an important antioxidant. However, it can also act as a pro-oxidant in the presence of certain metal ions and oxygen. The richest sources in the British diet are citrus fruit, fruit juices and soft fruit. Other sources include green vegetables, other fruit, peppers and potatoes, especially new potatoes.

Vitamin D

Vitamin D is involved in calcium homeostasis. As well as helping to control plasma calcium levels, it may also have a direct effect on bones. Exposure of skin to sunlight results in the manufacture of vitamin D, but there are few dietary sources of vitamin D. Oil-rich fish such as herring, pilchards, sardines and tuna, meat, eggs, and fortified foods including margarine, some yogurts, evaporated milk and breakfast cereals are the main sources.

Vitamin E

Vitamin E is the major lipid-soluble antioxidant in membranes and can be seen as offering protection against free radical damage. Immune function is influenced by vitamin E. Vegetable oils, margarine, wholegrain cereals, eggs, vegetables (especially dark green leafy types) and nuts provide most of the vitamin E.

Vitamin K

Vitamin K is needed for the synthesis of pro coagulant factors. It may also be important for a strong skeleton. Green leafy vegetables are the richest source in the British diet. It is also found in other vegetables, fruit, dairy produce, vegetable oils, cereals and meat.

On the whole, Every vitamin is essential to our body as long as it has been taken with precaution. If unsure, always ask for the doctor's advice even though it's just vitamins.
