Vitamins

Vitamins are essential organic compounds that are required in small quantities for the normal functioning of the human body. They are necessary for various biochemical processes, such as growth, digestion, and nerve function. Vitamins are classified into two categories: fat-soluble and water-soluble.

Fat-Soluble Vitamins

• Vitamin A: Essential for vision, immune function, and reproduction.
• Vitamin D: Important for bone health and calcium absorption.
• Vitamin E: Acts as an antioxidant and helps protect cells from damage.
• Vitamin K: Plays a key role in blood clotting and bone metabolism.

Water-Soluble Vitamins

• Vitamin C: Required for the synthesis of collagen and the immune system.
• Vitamin B1 (Thiamine): Helps convert food into energy and is essential for nerve function.
• Vitamin B2 (Riboflavin): Involved in energy production and cellular function.
• Vitamin B3 (Niacin): Important for metabolism and cardiovascular health.
