Did you take before/after blood tests to confirm you had low blood levels and that drinking milk helped? A cup of milk is roughly 150iu, while recommended supplements range from 600 to 2000iu. Also, lactose-free milk is common nowadays.

I had taken one a long while ago in a checkup and my levels were abysmally low. That explained why I was miserable at the time.

Supplemented for a bit and it was a stark turn around, but I fell out of the habit of doing it and forgot. I drink a half gallon a day easily.
