Common and Scientific Names of Vitamins

What are Vitamins?

Vitamins are organic compounds that are essential for the normal functioning, growth, and maintenance of the human body. While the body can synthesize some vitamins, most must be obtained from the diet since the body either cannot produce them or produces insufficient amounts.

Types of Vitamins?

Vitamins are classified into two main categories:

  1. Fat-soluble vitamins: These vitamins are soluble in fats and are stored in the body's fatty tissues and liver. The fat-soluble vitamins include:
    • Vitamin A: Important for vision, immune function, and healthy skin.
    • Vitamin D: Essential for calcium absorption and bone health.
    • Vitamin E: An antioxidant that protects cells from damage.
    • Vitamin K: Vital for blood clotting and bone health.
  2. Water-soluble vitamins: These vitamins are soluble in water and are not stored in the body for long periods, so they need to be replenished regularly. The water-soluble vitamins include:
    • Vitamin C (Ascorbic acid): An antioxidant that supports the immune system and collagen production.
    • B-vitamins: B-vitamins play various roles in energy production, metabolism, and nerve function.
