I have been taking Calcium Citrate+D3 for several months now, plus one 5,000 mg D3 daily. When I consistently take it (at lease 3 tablets a day) I have a constant problem with itching and redness in the genital area, especially at night, which keeps me awake. When I stop taking it for a day, the itching and redness disappears. Could this possible be from the Calcium Citrate+D3? I have taken Oscal in the past, could I possible take this instead? Thank you.
