What is Zinc?
Zinc is a trace mineral that is required by our body to process certain biochemical reactions. The mineral cannot be synthesised by our body, so it can only be consumed through diet.
Zinc is involved in various body functions like immune function, DNA synthesis, growth and catalyst in certain enzyme reactions.
Zinc also helps to synthesise DNA and proteins required for the body. Pregnant women will require zinc for the growth and development of the foetus brain.
Zinc is only required in small quantities for our body, and the recommended daily allowance level is 11 mg and 8 mg for men and women, respectively. If consumed more than the recommended level, it can lead to complications.
Some of the common needs that our body requires zinc are for

If a person does not consume enough zinc, it can lead to zinc deficiency and certain health conditions like weight loss, diarrhoea, vision problems, skin rash, loss of appetite, reduced sense of taste and smell and weakened immune system.
