What are vitamins?
  • Vitamins and minerals are the micronutrients to carry out various everyday functions. Vitamins and minerals must be obtained from the food we eat.

 

  • Vitamins are organic substances generally classified as fat-soluble or water-soluble vitamins. Fat-soluble vitamins include vitamin A, vitamin D, vitamin E, and vitamin K, which dissolve in fat and tend to accumulate in the body.

 

  • Water-soluble vitamins include vitamin C, B vitamins, and choline (a vitamin B-complex). Water-soluble vitamins are dissolved in water before the body can absorb them and, therefore, cannot be stored. Thus, any water-soluble vitamins unused by the body are primarily lost through urine.

 

  • The following table summarizes water-soluble and fat-soluble vitamins.
