I was tested & found deficient so started taking 2000 iu for 60 days, my knees that my doctor & orthopedic surgeon both told me needed replaced are so much better but still sore after standing a long time, so I increased to 10000 iu 2 weeks ago and knees are fine, also improved my fingers which had limited movement since I broke them 2 -3 years ago. Feel like a new person, get tested in another week to see what level is now. I can’t believe such a simple fix!
