**The Essential Guide to Vitamins: What You Need to Know**

Vitamins are organic compounds vital for maintaining health and preventing deficiencies. Humans require 13 essential vitamins, each playing unique roles in bodily functions like immunity, energy production, and cell repair. They’re categorized into two groups: **water-soluble** (B-complex and vitamin C) and **fat-soluble** (A, D, E, K).

**Water-soluble vitamins** dissolve in water and aren’t stored long-term. For example, vitamin C boosts immunity and collagen synthesis, while B vitamins (e.g., B12, folate) aid metabolism and nerve function. These are easily depleted, requiring daily intake from foods like citrus fruits, leafy greens, and whole grains.

**Fat-soluble vitamins** are stored in body fat and liver. Vitamin D supports bone health and immunity, synthesized through sunlight exposure. Vitamin A promotes vision and skin health, found in carrots and sweet potatoes. Vitamins E and K act as antioxidants and aid blood clotting, respectively.

While most vitamins come from a balanced diet (fruits, vegetables, nuts, lean proteins), certain groups—like pregnant women, vegans, or those with malabsorption issues—may need supplements. However, excessive intake, particularly of fat-soluble vitamins, can cause toxicity.

Always prioritize natural food sources and consult a healthcare provider before starting supplements. Understanding vitamins helps you make informed choices for long-term wellness. Stay nourished, stay healthy!
