Application

Beta Carotene USP Reference standard, intended for use in specified quality tests and assays as specified in the USP compendia. Also, for use with USP monographs such as:
  • Beta Carotene Capsules
  • Beta Carotene Preparation
  • Carotenes
  • Oil-Soluble Vitamins Oral Solution
  • Spirulina Tablets
  • Spirulina
  • Oil-Soluble Vitamins with Minerals Oral Solution

Biochem/physiol Actions

The most important of the provitamins A, β-carotene can be classified as an antioxidant due to its inhibition of radical initiated peroxidation in vitro. However, in vivo it appears to act either as an antioxidant or a prooxidant depending on cellular environment. It reduces the incidence of many cancers, but enhances lung cancer incidence in smokers.
