The RX Version is D2, and plant derived... it is not active in human bodies.
Doctors continue to use this poor product after testing you.
What a waste!
OTC D...is D3...the active form. You can buy it online 50,000IU and below. I personally take 10,000 IU daily. (after my testing showed that 5,000 wasn't doing enough at a level of 43.)
edit... that link has changed:
