Pure Encapsulations' Vitamin A + Carotenoids is essential to the healthy functioning of a number of
biological processes, including vision, the integrity of mucosal and
epithelial surfaces, and the body's immune defense system. While many individuals are able to convert provitamin A carotenoids, like beta carotene, into active vitamin A, recent research has revealed that genetic variations can limit the ease of this conversion for some. Genetic variations in the enzyme BCMO1 (β-Carotene 15,15’-monooxygenase 1) can decrease the conversion efficacy of carotenoids into retinal by up to 69%. Known as single nucleotide polymorphisms (SNPs), these common variations can be bypassed with dietary retinol (vitamin A). Since variations in the BCMO1 gene have also been associated with macular pigment density, this formula includes a blend of lutein, zeaxanthin and astaxanthin. Lutein and zeaxanthin, the two carotenoids found in macular pigment, are antioxidants that help to maintain good eye health. Astaxanthin further supports antioxidant defences by protecting the phospholipid membranes of cells from oxidative damage.Recommended Dosage: Adults: Take 1 capsule daily with a meal or as directed by a healthcare practitioner.Caution: Consult a healthcare practitioner prior to use if you are pregnant or breastfeeding.
