Vitamins are classified as water soluble and fat soluble. Fat soluble vitamins are stored by the body as they are dissolved in the fats or lipids present in the body. Your body cannot store the vitamins that are soluble in water. Being soluble in water, they are thrown out of the body along with the waste material, regularly. Therefore you are expected to refill your body with the water soluble vitamins and minerals every day.
Eight B vitamins which comprise vitamin B complex and vitamin C are the 9 vitamins which are soluble in water. Vitamins B1 (thiamine), B2 (riboflavin), B3 (niacin) and B7 (biotin) are required for energy production, vitamin B6 (pyridoxine) plays an important role in amino acid metabolism, and vitamin B12 (various cobalamins) and B9 (folic acid) are essential for important metabolic processes like the process of cell division. Vitamin B5 (pantothenic acid) helps prevent skin conditions like acne and the rare condition known as paresthesia (feeling of 'pins and needles' or numbness in skin with no long term physical effect). Vitamin C is an antioxidant vitamin and it helps reduce the effects of free radicals on the body. It lowers the levels of bad cholesterol in the body and strengthens your immune system. It is essential for maintaining and repairing body tissues. It encourages absorption of calcium and iron and strengthens the blood vessels.
Yeast, liver, eggs and some vegetables contain B vitamins. Most fruits and some vegetables like broccoli, Brussels sprouts, cauliflower, cucumber, carrot, tomato, turnip, etc. contain vitamin C. These are the foods that you can incorporate into your diet to avoid vitamin deficiencies.
