What are Vitamin and minerals?
Vitamins
Vitamins are organic compounds that our body needs in small quantities to function properly. They are classified into two types:

Minerals
Minerals are inorganic elements that are vital for process such as nerve transmission, bone formation and enzyme activation. They are divided into:
Macrominerals – e.g. Calcium, Magnesium, Sodium, Potassium
Trace minerals – e.g., Iron, Zinc, Copper, Iodine, Selenium
