So I decided to take vitamin d3 (4000iu) for the first time last week and got the beginnings of 2 new cysts the day after. I stopped for a few days as a result. ButthenI decided to try itagain to test if it was really the cause... and low and behold, 2 new cysts arrived the day after that!

Can vitamin d3 really cause a reaction this quickly? I know it can increase testosterone levels.

Has anyone else had this reaction? All I see is good things online.
