without comments


Micronutrients are called micronutrients due to the fact that only minute amount of these are essential for the body. These are very important for the growth, development and overall performance of the body. At cellular level, these micronutrients are required for the synthesis of hormones, enzymes and other vital substances. When these micronutrients are not consumed as required, the consequences may be severe.

Micronutrients and their importance:

Micronutrients include trace elements, organic acids, macrominerals and vitamins. They are important for:


Calcium: Bones, muscles, metabolism

Chloride: Acid/base balance, fluid regulation, impulse transmission in neurons

Magnesium: Nuclear material, ATP production, brain fluid, enzymes

Phosphorus: Nuclear material, ATP production, bone, enamel of the teeth, cellular structures

Potassium: Impulse transmission in neurons, muscles, osmotic balance

Sodium: Blood pressure, osmotic balance, importance cellular activities

Iron: Blood cells, oxygen transport, muscle cells

Sulphur: Proteins and co-factors, metabolism

Organic acids:

Acetic acid, Citric acid, Malic acid, Lactic acid Taurine and Choline are the organic acids that have certain important role in the body.


Vitamin A (retinol): Visual cycle, reproduction, growth, epithelial tissue maintenance, metabolic functions.

Vitamin B complex: Nervous tissue, ATP and NADP, proteins, important co-enxymes

Vitamin C (Ascorbic acid): Collagen formation, connective tissue, anti-oxidants

Vitamin D: Calcium regulation.

Vitamin E (tocopherol): Anti-oxidants, muscles strength

Vitamin K: Blood clotting

Trace elements:

Boron, Chromium, Fluoride, Manganese, Molybdenum, Selenium, Zinc, Cobalt, Copper and Iodine are important trace elements that should be taken in diet in small amount. Deficiency of iodine leads to thyroid gland abnormalities.
