Vitamins are found in the food we select for our everyday diets and if we make sensible choices from a wide selection of foodstuffs, on a daily basis, our need for supplementation should be minimal.
If you would like to ensure that your body has access to all of the vitamins it needs, without taking supplements, be sure to select foodstuffs from each of the following groups as they contain naturally occurring vitamins:
1. Vitamin A
Vitamin A is available from two primary food group sources. Provided you do not have a history of high cholesterol problems you can obtain Vitamin A from animal sources - meat, dairy products and cod liver. If you need a lower cholesterol option vitamin A can also be obtained from beta-carotene sources - carrots, sweet potatoes, spinach, mango, broccoli and other fruits and vegetables that have red and yellow coloured skins.
2. Vitamin B1
Vitamin B1 is also known as Thiamine and this can be found in whole grain bread, cereal and
pasta. This vitamin can also be found in meat, fish, pulses and beans, dairy products
and fruits and vegetables.
3. Vitamin B2
Vitamin B2 is also known as Riboflavin and can be found in dairy products. Smaller quantities
of this vitamin can also be sourced from chicken, green vegetables, fruits and almonds.
4. Vitamin B3
Also known as Niacin, Witamin B3 is found in dairy products, poultry, fish, lean meat, nuts and eggs. Some cereals also contain traces of Vitamin B3.
5. Vitamin B5
Pantothenic Acid is another name for Vitamin B5. This vitamin can be sourced from fish, dairy products, poultry, beef, brassicas, sweet potatoes, peanuts and peas.
6. Vitamin B6
Vitamin B6, also known as Pyroxidine, is contained within bananas, watermelons and tomatoes, chicken, broccoli, spinach, potatoes, white rice, peanuts, oats and fortified cereals.
7. Vitamin B12
Vitamin B12 is found in meat, poultry, fish, shellfish and dairy products.
The best source of folate is green, leafy vegetables. Alternative sources are: tomato juice, peas, wheat germ, oranges and mushrooms.
9. Vitamin C
Vitamin C is commonly sourced from citrus fruits, strawberries, melon and cranberries.
10. Vitamin D
The body can manufacture its own Vitamin D provided the skin is exposed to sunlight for part of the day There is a theory that, with the increased use of sun blocks, more people are experiencing symptoms of Vitamin D deficiency. Vitamin D is also present in dairy products,
poultry, and cereals.
11. Vitamin E
Vitamin E is obtained from peanuts, whole grains, wheat germ, corn, nuts, olives, spinach and other green and leafy vegetables.
12. Vitamin K
Vitamin K, like Vitamin D, can be manufactured by the body although Vitamin K is produced by friendly bacteria in the gut. Vitamin K is found in leafy green vegetables, soybeans, cereals, fruits, potatoes, dairy products, meat and poultry.

The use of nutritional supplements is possibly the most commonly used form of alternative medicine in the Western world
Nutritional supplementation is often integrated into conventional medical treatment for some conditions. Pregnant women, for instance, are prescribed supplements with vitamin B and folic acid to help prevent neural tube defects in their unborn children. In many conditions where one of they symptoms is a deficiency of a particular nutrient, treatment includes supplementation with that nutrient. Many practitioners, however, believe that all people need to take nutritional supplements for optimum health. They maintain that it is impossible to consume a diet that provides all the necessary nutrients because of soil depletion, pollution, environmental contaminants and modern processing methods.
In addition, there are many claims made for super supplementation as treatment for some illnesses. These include recommendations of megadoses of antioxidant vitamins and minerals for prevention of cancer, treatment of diabetes or asthma or other chronic conditions.
There is a great deal of evidence to support the theory that nutrition plays a significant role in health, and throughout the course of history, many diseases have been discovered to be caused by nutritional deficiencies. Classic examples of this are scurvy and rickets, both diseases that were found to be the symptoms of deficiencies of important vitamins. More recently, researchers have found that patients exhibiting symptoms of depression benefit from taking fish oil supplements which increase their intake of omega 3 fatty acids, and from vitamin B supplements, often without any other drugs prescribed. Calcium has been found to prevent osteoporosis and other bone diseases, and potassium supplements are helpful for those with heart conditions.
None of this should come as a surprise. Our bodies depend on our intake of nutrients to create new cells and repair old ones. When we don’t provide enough of a needed nutrient, the result is substandard functioning. Nutritionists suggest that many of the diseases that are on the
Criticism for nutritional therapies takes one of two tacks – either the nutritional supplements are not needed, or are ineffective, or nutritional supplements are unsafe because they are untested and unregulated.
In an area as wide as this one, there is some truth to both criticisms. Unscrupulous advertisers make wild claims for some nutritional supplements with an eye on the consumer’s wallet rather than his health chart. Since nutritional supplements are considered to be ‘food’ rather than medicine, there is little oversight or testing required unless a product proves to be unsafe AFTER it is released.
For this reason, it’s important that consumers do their research. Some nutritional supplements have a great deal of research to support their effectiveness. Others show no positive results at all. Likewise, some manufacturers scrupulously follow their own testing and packaging procedures to ensure that their product is effective, safe and uncontaminated. It’s only by doing your own research that you’ll know which is which.
In addition, since many nutritional supplements can interfere with medications and treatments for illnesses and infections, it’s very important to discuss everything that you’re taking with your doctor.
