Falling D3 levels
I have been taking 10,000IU of vit. d3 for 1 yr. in an effort to raise my level which was at 20. The first time i had my blood checked it had risen to 45. recent test has showed my level to be dropping even though I'm still taking the same amount. What may be causing the reversal?
I am a cancer survivor an was on chemo three years ago.
I am currently taking Levothyroxine.
