The Chemistry of Vitamins: Tiny Molecules, Big Impact

Vitamins are organic compounds the body needs in small amounts to stay healthy.
Unlike carbs, proteins, or fats, vitamins don’t provide energy—but they unlock it.
Fat-soluble vitamins (A, D, E, K) are stored in body fat and used over time.
Water-soluble vitamins (C and B-complex) dissolve in water and must be replenished daily.
Vitamin C is a powerful antioxidant that also helps build collagen for skin and bones.
The B-vitamins act as coenzymes, helping enzymes drive essential chemical reactions.
Vitamin D, produced in skin by sunlight, regulates calcium for strong bones.
Deficiencies in vitamins can cause diseases like scurvy, rickets, or anemia.
Chemists can synthesize vitamins, making supplements widely available worldwide.
Though tiny in size, vitamins are chemical keys that keep life’s machinery running smoothly.
