Nutrition Guide: Micronutrients
Nutrients are substances necessary for proper bodily function.
The nutrients required in small quantities are called Micronutrients.
We can categorized the micronutrients into 2 types:
- Vitamins

Vitamins
Vitamins are organic compounds not manufactured by the body other than proteins, carbohydrates and fats that are required for growth, maintenance and repair. Vitamins require no digestion and are absorbed directly into the blood stream. The thirteen vitamins identified are divided into two groups, fat-soluble and water-soluble.
The fat-soluble vitamins, which include A, D, E, and K are stored in the liver and in body fat. Mega doses of fat-soluble vitamins can produce a toxic effect in the liver and can accumulate in the tissues.
The body does not store water-soluble vitamins. The kidneys excrete excess or Mega doses of these vitamins. However, toxicity has been reported with A, niacin, C, D and B6.
