My gynecologist prescribed vitamin d 50,000 unit to take every two weeks, but my regular MD advised me not to take it because it could cause calcium build up around my heart. I have a family history of heart problems in my family. I do not know where to take it or not.
I would suggest you get a vitamin D done, if on the lower side you should supplement it without a doubt, generally they are available in 60000 U, which you should take 1/week for 6 weeks and then once a month for 6 months.  After that retest. It's a completely false nothing that it will cause calcium deposition around your heart and I would assure you it wouldn't.  However, without testing long term supplementation is not what I would recommend Regards
