I was put on that Calcium / Vitamin D3 regimen in preparation for starting Letrozole. It's to proactively counter potential side effect of bone loss from letrozole. The first day and subsequent two days after I had tremendous lower leg pain at night. I stopped and the leg pain is gone.
Calcium carbonate is not a good form of calcium to take. It doesn’t get well absorbed. It’s better to get calcium citrate and take magnesium citrate or bisgycinate with it, as well as D3/K2. All of these need to be taken to make sure you have a good absorption into the bones and not the veins.
I don't take any supplements, but I know I get a leg calf cramp if I
stretch my legs first thing upon waking in the morning. I'd rather have
labor pains! As far as my legs go like walking or standing for a log
time, I've had that problem for years but that's caused by my back
problems. Osteoporosis.. So I live with it.. Although I did run when yellow
jackets got mad and were chasing me.
Be sure to take the D3 with K2 as that’s what deposits the calcium directly into the bones otherwise it goes to other areas in your body.
