How Vitamins Work: The Science Behind Vitamins:

Vitamins are essential substances that the body cannot produce in sufficient quantities, so they must be obtained from food.

Vitamin deficiencies can lead to serious health issues, as illustrated by historical examples like scurvy (Vitamin C deficiency) and rickets (Vitamin D deficiency).

There are 13 essential vitamins, categorized into fat-soluble (A, D, E, K) and water-soluble (C and B-complex) vitamins.

Fat-soluble vitamins are stored in the body's fatty tissues and liver, requiring fat for absorption and posing a risk of toxicity if overconsumed.

Water-soluble vitamins are not stored in the body in large quantities and are excreted in urine, making daily intake important to prevent deficiencies.

Vitamin A is crucial for vision, cellular growth, and immune function, with deficiencies leading to night blindness and other issues.

Vitamin D is essential for calcium absorption and bone health, with deficiencies causing rickets, osteoporosis, and osteomalacia.

Vitamin K plays a key role in blood clotting, preventing excessive bleeding and is particularly important for newborns.

Vitamin E is a powerful antioxidant that protects cells from oxidative stress, supports immune function, and maintains skin health.

Vitamin C is important for immune defense, collagen synthesis, and iron absorption, with deficiencies leading to scurvy.

The B-complex vitamins (B1, B2, B3, B5, B6, B7, B9, B12) are essential for energy production, DNA synthesis, and overall cellular function.

Vitamin B12 is crucial for nerve protection and red blood cell production, with deficiencies common in vegans and older adults.

Vitamin deficiencies can manifest as specific syndromes, such as pellagra (Vitamin B3 deficiency) and beriberi (Vitamin B1 deficiency).

Fat-soluble vitamins can accumulate in the body, posing a risk of toxicity if consumed in excessive amounts, unlike water-soluble vitamins.

The body's need for vitamins varies based on diet, age, and health status, making balanced intake essential for overall well-being.
