If you've had an infection (chicken pox) this suggests that your immune system is struggling. Because you are a young man you will be needing a lot of zinc (it's used for growth, and sexual development) - and this is also needed for the skin. If you have white spots on your fingernails then you are certain to have low zinc status. If so, do the following:
1. For the first week: take 60mg/day - take 30mg thing at night on an empty stomach (other nutrients interfere with its absorption), and the other dose with breakfast.
2. For the next 3 months take 45mg/day. Again take 30mg last thing at night on an empty stomach (other nutrients interfere with its absorption), and the other dose with breakfast.
3. If your skin has improved - then each month reduce the daily dose by 15mg/day, until you are taking 15mg/day.
Always take a multivitamin. But do not take it at the same time as the zinc - because other nutrients interfere with its absorption.
