Reply To: I am in my 6th week of taking 10,000iu for vitamin D deficiency. My level was 28ng/ml. I have symptoms of depression and muscle weakness. How long of supplementing until I feel relieved of my symptoms?
IAW, could you give me research with vitamin d deficiency on poor posture? I’m wondering if my weak muscles are due to vitamin D deficiency. I get my new vitamin D levels tomorrow. If my results come back around normal … 50ng/ml, do you suggest I quit taking 10kiu and return to a maintenance dose of 5kiu?
