The upper limit for those aged 19 and above is 4000 IU per day. However, the recommended daily allowance (ages 1-70) for vitamin D is 600 IU per day; 15 micrograms.
 Good sources of vitamin D include rainbow trout and salmon, though sardines and whole milk can also suffice.
 
 Normally supplementing vitamin D is not necessary as we synthesise the vitamin through UV rays. More so if you're already consuming foods such as those I've mentioned above.
