What are Vitamins?
Vitamins are organic compounds that are essential for the body to grow, develop, and function properly. They are required in small amounts and must be obtained through food because the body either does not produce them at all or only in insufficient quantities.
Types of Vitamins
Vitamins are classified into two main categories:
1. Fat-Soluble Vitamins
These are stored in the body's fat tissues and liver, and are used as needed. They include:
Vitamin A – Good for vision, immune system, and skin.
Vitamin D – Helps in calcium absorption, bone health.
Vitamin E – Acts as an antioxidant, protects cells.
Vitamin K – Important for blood clotting.
2. Water-Soluble Vitamins
These are not stored in the body; excess amounts are excreted in urine. They must be consumed regularly. They include:
Vitamin B-complex group (like B1, B2, B3, B6, B12, folic acid, etc.) – Help in energy production and red blood cell formation.
Vitamin C (Ascorbic acid) – Boosts immunity, helps in iron absorption and wound healing.
