How long it will take my vitamin d levels to raise from 19 to healthy level if i took 4000 iu of vitamin d daily? is 4000 adequate dose to supplement?
A doctor has provided 1 answer
Yes: 4000 units of vitamin D3/day is sufficient. It may take about three months for your stores of vitamin D to be replenished and the blood level to be at or above 30.
