Hi!
Yes, zinc supplements are known to improve immunity but shouldn’t be taken without a prescription and detailed assessment of current health conditions.
Zinc supplements are being used in the treatment of covid-19 along with many other medications, so do not start taking any medication by reading news/ google etc.
include dry fruits , fresh fruits and vegetables, 2 litres of water, milk and milk products, good sleep and light exercise daily to keep immunity at optimum levels.
A detailed assessment is necessary to provide more support and prescription of medication, specially for children.
