Vitamins
Vitamins are essential organic compounds that the human body requires in small amounts for proper growth, function, and overall health, with deficiencies causing specific, well-documented diseases.
Discovered largely through investigating diseases caused by their absence, these essential nutrients occupy a unique category: substances the body cannot produce on its own but absolutely requires to function properly.
Essential But Not Self-Produced
Vitamins are organic compounds the human body requires for proper function but generally cannot synthesize on its own in sufficient quantities, requiring intake through diet or supplementation.
Discovered Through Deficiency Diseases
Many vitamins were first identified through research into deficiency diseases, such as the discovery of vitamin C's role in preventing scurvy among sailors on long ocean voyages.
Fat-Soluble and Water-Soluble Categories
Vitamins are broadly categorized as either fat-soluble (A, D, E, and K), which the body can store, or water-soluble, which must be replenished more regularly through diet.
Supporting Diverse Bodily Functions
Different vitamins support a wide range of essential bodily functions, from vitamin D's role in bone health to vitamin A's importance for vision, reflecting their diverse and critical biological roles.
