Understanding Vitamins: The Basics of Nutrition
Vitamins are organic compounds your body needs in small amounts to function properly. Unlike carbohydrates, fats, and proteins, they don’t provide energy directly—but they help your body use energy efficiently.
Why vitamins are essential
Vitamins support:
- Energy production
- Immune defense
- Brain function
- Skin and hair health
- Bone strength
- Hormonal balance
Without enough vitamins, even a healthy diet can feel incomplete.
Two main types of vitamins
Vitamins are grouped into two categories:
- Fat-soluble vitamins: A, D, E, K (stored in the body)
- Water-soluble vitamins: B-complex and C (need daily intake)
This difference matters because it affects how often you need them.

Advanced Nutrition Tips for Better Vitamin Absorption
Getting vitamins is one thing—absorbing them is another.

Avoid nutrient blockers
Certain habits reduce vitamin absorption:

Cook smartly
Some vitamins are sensitive to heat:
