Thank you very much for your reply Mrs.D and so sorry for the delayed acknowledgement, it has not been easy for me the past days.

You are so helpful and I appreciate it. I will take the minimum supplements you suggested.

Other than Ethambutol, the other antibiotics I take are Rifampin and Azithromycin.

Again, thank you.

I had my VitD3 tested 2 weeks ago and the result was 40. I was expecting to be h igher than this because of my supplementation. I was taking 2000mg of VitD3 prior to the test. I remember this was about the same number when I had it tested 2 years ago when I was not taking the supplement. I increased it to 4500mg after I got hte result. The Rifampin must be affecting the absorption of my VitD3.
