I Want Take Precautions So Please Refer Me Some Tablets
I understand your concern and your intention to take supplements to boost immunity. However any form of supplements will not replace a healthy diet and physical exercise with respect to boosting immunity. So inaddition to supplements I will recommend you take a good healthy diet containing good amount of fruits and vegetables.
You can also take tab limcee (vitamin C) once daily and tab zincovit (multivitamin and zinc) supplements for the benefits you are looking for.
Hope this helps. Let me know if you need clarifications.
