Make sure not to take more than that without consulting with a health professional.

The upper level of harmless intake is set at 4000 IU, or 100 micrograms, per day.
However, up to 10,000 IU per day has not been shown to cause harm to healthy individuals
both the NHS and EFSA say Do not take more than 100 micrograms (4,000 IU) of vitamin D a day.
