    Vitamins are required in limited amount by the body for growth and development. And one should not exceed this limit as it is of no advantage to the body. Naturally, vitamins and others nutrients are present in micro amount in food items. So it is very difficult for proteins to be consumed in excess amount through natural food alone. Instead, a regular healthy diet is usually sufficient enough to meet the vitamin requirement.

    But, with nutracuetical, supplement and even the basic foods and drinks being fortified with vitamins, minerals and other nutrients; the chances of getting overdose increases. Any nutrient can be potentially harmful if consumed in large quantity. We have many examples of vitamin overdose cited here for our understanding.

    • If taking a supplement, always check the label claim to determine vitamin value
    • Start a nutritional supplement under physicians advice
    • Stick to the doctor recommended dose. And do not exceed it
