I have gone for full body checkup recently. And reports says my d vitamin is very deficient. Vitd25oh 12.10 ng/ml. Doctor suggested use Calcirol 1g (60, 000 IU) sachet once in a week with milk. One of my friend who's doing research (in USA) on D3 and other vitamins suggested instead of taking 60, 000 IU once in a week, Research results shows that 10, 000 IU per day capsules taking for 1 month have better results. Someone suggest what are the best brand d3 vitamin capsules for 10, 000 IU available in india?
