Sec.  184.1950  Vitamin D.

    (a) Vitamin D is added to food as the following food ingredients:
    (1) Crystalline vitamin D2 
(C28H44O, CAS Reg. No. 50-14-6), also known as 
ergocalciferol, is the chemical 9,10-seco(5Z,7E,22E)-5,7,10(19),22-
ergostatetraen-3-ol. The ingredient is produced by ultraviolet 
irradiation of ergosterol isolated from yeast and related fungi and is 
purified by crystallization.
    (2) Crystalline vitamin D3 
(C27H44O, CAS Reg. No. 67-97-0), also known as 
cholecalciferol, is the chemical 9,10-seco(5Z,7E,)-5,7,10(19)-
cholestatrien-3-ol. Vitamin D3 occurs in, and is isolated 
from, fish liver oils. It is also manufactured by ultraviolet 
irradiation of 7-dehydrocholesterol produced from cholesterol. It is 
purified by crystallization. Vitamin D3 is the vitamin D form 
that is produced endogenously in humans through sunlight activation of 
7-dehydrocholesterol in the skin.
    (3) Vitamin D2 resin and vitamin D3 resin are 
the concentrated forms of irradiated ergosterol (D2) and 
irradiated 7-dehydrocholesterol (D3) that are separated from 
the reacting materials in paragraphs (a) (1) and (2) of this section. 
The resulting products are sold as food sources of vitamin D without 
further purification.
    (b) Vitamin D2 and vitamin D3 as crystals meet 
the specifications of the Food Chemicals Codex, 3d Ed. (1981), pp. 344 
and 345, which is incorporated by reference. Copies are available from 
the National Academy Press, 2101 Constitution Ave. NW., Washington, DC

Administration (NARA). For information on the availability of this

FDA is developing food-grade specifications for vitamin D2 
resin and vitamin D3 resin in cooperation with the National 
Academy of Sciences. In the interim, these resins must be of a purity 
suitable for their intended use.
