Synthetic beta-carotene is comprised mainly of all-trans beta-carotene with small amounts of 13-cis beta-carotene and even smaller amounts of 9-cis beta-carotene. Natural beta-carotene is principally derived from the algae Dunaliella salina and is comprised of all-trans beta-carotene and 9-cis beta-carotene. Three mg of beta-carotene is equal to 5、000 UIs. Supplemental intake of beta-carotene ranges from 3-15 mg、day.、GRADES: ACCORDING TO USP、UNITS OF VIT A、SOLD AS PURE CRYSTALS、AS SOLN IN VARIOUS OILS、AS COLLOIDAL DISPERSION.
