Tamoxifen and calcium with magnesium &d3. Anyone taken it?

I started Tamoxifen on jan 1 2015 as I had Mx due to DCIS. I was already taking calcium &magnesium &b3 for cramps in my legs. My DR says calcium is not good for the heart but the cramps and pain is much so I am still taking it. Please is anyone taking this combination. Is it true that the calcium is actually good for pre menopausal women on tamoxifen.

not sure sorry. I take VitD as mine was low, but not calcium. are they keeping an eye on your heart?

D3 is good, which should help raise your calcium levels. I don’t think you need extra calcium on top of this incase you end up with too much. I take co enzyme q10 and something else for heart health.
