cpk is just vitamin d deficiency, statins are the most common drugs to evelate cpk and vitamin d lowers it and prevents elevation.also vit b 12 can be added but it is vit d to prevent/lower cpk
if it was tdf you were using it it changes pth/vit d and must be taken with vit d
So why wasn't my cpk high before medicine? I take between 15,000 -25,000 vitd a day. It's not vitamin d.
