Vitamins & Supplements

Why Can't Your Body Just Make Vitamins

Since generally we cannot synthesize vitamins or can only do so in amounts insufficient to meet our body needs, they must be obtained from the diet or from some synthetic source, hence vitamins are called essential nutrients. Since the body simply cannot make many of the vitamins it needs, a good liquid multivitamin is crucial. If a vitamin is absent from the diet or is not properly absorbed by an organism, a specific deficiency disease may develop or the individual may feel tired, irritable and may not be as mentally sharp.

There are two groups of essential vitamins, each classified according to the materials in which they will dissolve. Fat-soluble vitamins, A, D, E and K, dissolve in fat before they are absorbed in the blood stream and are stored in the liver. Water-soluble vitamins on the other hand dissolve in water, are not stored and are eliminated regularly in urine. We, therefore, need a continuous supply of these vitamins. The water-soluble vitamins are the B-complex group and vitamin C. Water-soluble vitamins are easily destroyed or washed out during food storage or preparation (heat, light, etc). To reduce vitamin loss, refrigerate fresh produce, keep milk and grains away from strong light, and use the cooking water from vegetables to prepare soups.

Vitamin C is plentiful in citrus fruits, broccoli, strawberries, melon, green pepper, tomatoes, dark green vegetables, potatoes. You get a lot of Vitamin B1 in pork, liver, whole grains, enriched grain products, peas, meat, legumes. Liver, milk, dark green vegetables, whole and enriched grain products, eggs are excellent sources of vitamin B2. Niacin can be found in liver, fish, poultry, meat, peanuts, whole and enriched grain products.

Pork, meats, whole grains and cereals, legumes, green, leafy vegetables are rich in vitamin B6, while liver, kidney, dark green leafy vegetables, meats, fish, whole grains, fortified grains and cereals, legumes, citrus fruits are great sources of folic acid.

Vitamin B12 is found only in animal foods such as meats, liver, kidney, fish, eggs, milk and milk products, oysters, and shellfish and it needs an additional “intrinsic factor” produced in the stomach to function properly. Liver, kidney, meats, egg yolk, whole grains, and legumes are good sources of panthotenic acid, which is also made by intestinal bacteria. Biotin is found in the liver, kidney, egg yolk, milk, most fresh vegetables, and it is also made by intestinal bacteria. Vegetarians should strongly consider supplemeting with these B vitamins, lest they fail to obtain enough from their diet.

An important point to note is that we absolutely need vitamins to function effectively and be healthy. Our bodies cannot make many of the vitamins that we require on a daily basis. We must, therefore, find them in our food, and by taking a liquid multivitamin supplement.

A vitamin is an organic molecule required by a living organism in minute amounts for proper health. An organism deprived of all sources of a particular vitamin will eventually suffer from disease symptoms specific to that vitamin.
