Vitamins can be considered in two major categories:
• water-soluble vitamins
• fat-soluble vitamins

The water-soluble vitamins include vitamin C, B-complex vitamins, and others.

There is a daily requirement for water-soluble vitamins. This is because they are
excreted continuously with the urine.

On the other hand, fat-soluble vitamins can be accumulated in the fat of the
body.

Tab1 Water soluble – Vitamin B1
Vitamin B1 (Thiamine Hydrochloride). Vitamin B1 is present in liver,
bananas, lean pork, and whole grain cereals.

Tab2 Water soluble – Vitamin B2
Vitamin B2 (Riboflavin). Riboflavin is found in milk, milk products, leafy
green vegetables, fruit, and liver.

Tab3 Water soluble – Vitamin B6
Vitamin B6 (Pyridoxine Hydrochloride). Vitamin B6 is found in whole grain
cereals, yeast, milk, fish, eggs, and liver.

Tab4 Water soluble - Nicotinic acid and Nicotinamide
Nicotinic Acid (Niacin) and Nicotinamide (Niacinamide). These are
present in meat, liver, milk, peanuts, and whole grain cereals.

Tab5 Water soluble – Vitamin B12
Vitamin B12. Vitamin B12 is found in liver, milk, eggs, and cheese.
Tab 6 Water soluble - Folic Acid
Folic Acid. Folic acid is found in leafy green vegetables and liver.

Tab 7 Water soluble - Vitamin C
Vitamin C (Ascorbic Acid). Sources of vitamin C include citrus fruits,
tomatoes, bell peppers, paprika, and all leafy green vegetables.

Tab8 Fat soluble – Vitamin A
Vitamin A. Vitamin A is mainly obtained from yellow-colored vegetables of all
sorts (for example, carrots and squash.)

Tab9 Fat soluble – Vitamin D
Vitamin D. Vitamin D is produced in the skin by the activity of solar radiation.
It is also present in fish liver oils, butter, and egg yolk.

Tab10 Fat soluble – Vitamin K
Vitamin K. Vitamin K is important in blood clotting. It is actually produced by
microorganisms located in the large intestines. This source of vitamin K may be lost
during the administration of antibiotics. Vitamin K also occurs in such foods as alfalfa,
spinach, cabbage, and egg yolk.

Tab10 Fat soluble – Vitamin E
Vitamin E. The function of vitamin E in humans is not known. Research
indicates that vitamin E has important functions in various species, but the specific
function varies from species to species.
