I was diagnosed with vitamin-D deficiency (15 count as per test results). I started with Vitamin D medicines (10000 IU) per week. In meanwhile, I had chickenpox and by now, only very few blisters are left. But I am still having weakness. A few days back, I have also been detected with muscle spasm and getting physiotherapy for the same. So can you suggest which multi-vitamin will be suitable for me to overcome weakness along with dosage instructions.
