I've had a deficiency diagnosed, I'm worried about the prescribed integrators, since everyone is suggesting daily doses and I'm taking 15000ui/month in a single dose. what's better?
dunno about difference between effect of daily vs monthly dosage, but 15000IU per month is newborn dosage here in Europe for first year, 1 drop per day = 500IU, so I would not worry too much about such low dosage which is insufficient for adult anyway unless you spend lot of time outside exposed to sun
I'm taking 2500IU daily
