The body can produce up to 25000 IU/day in very sunny places on very pale skin. 10000IU/day is considered the safe upper limit. Whether or not that's a good idea long term is a different matter.

The body can produce over 250,000 IU in short order delivered as 25,000 IU a day as a controlled release through the skin. If you want this, the best idea is to spend 5 minutes in your underwear in a tanning bed. Dietary supplements can work, but it takes months.
