Steff can u tell me the brand names of those supplements?
I am sorry that is 10000 units daily not 50000
50.000iu daily is a lot, be sure to check calcium, creatinine, vitd25oh and intact pth.if intact pth falls below minimum level of normal it can be dangerous to keep that dose
also drink 2.5l of water with low calcium content daily and avoid all dairies in your diet
