Is there any risk in taking fat-soluble vitamins in large quantities? Explain.

Step 1 of 2

Vitamins are organic molecules that act as catalysts in several metabolic reactions. They either act as co-enzymes or their derivatives are directly involved in metabolic activities. Since they are very much essential for the metabolism, their deficiency causes several metabolic disorders. However, these vitamins are required by the body at very minute quantities.

Based on their solubility, vitamins are classified as water soluble and fat soluble vitamins. Water soluble vitamins are B-complex vitamins whereas fat soluble vitamins include A, D, E, and K.
