Fish liver oils, such as cod liver oil, 1 Tbs. (15 ml) provides 1360 IU (90.6 IU/ml)
Chemically there is not a difference. However, with a prescription it is possible to get higher dose tablets (up to 1500mg) with a prescription.
Vitamin D is produced by ultraviolet radiation on your skin. The UV light converts a precursor molecule to vitamin D.
10,000 IU or go to a physician and if your vitamin D level is low, he/she can give you prescription doses at 50,000 IU per pill which you take weekly for roughly 3 months. Afterward you get your levels checked to see where you fall. Be very careful taking doses higher than 5,000 IU daily if you don't know your current vitamin D status.
