Don't worry: As one of the safest substances known to man..Its very rare to overdose. I'm assuming you have a vitamin d deficiency at baseline. I'm not in favor of the 50, 000 unit approach and i see a lot of this in my HIV population. I recommend d3 2000 units a day. Have your pcp monitor your cholecalciferol level.
