Vitamin A plus Carotenoids formula includes a blend of lutein, zeaxanthin and astaxanthin to promote macular health.
Lutein and zeaxanthin are the two carotenoids found in macular pigment; as such, they act to support the integrity and density of the pigment, as well as optical lens health. Astaxanthin offers support for antioxidant defenses to protect retinal health.*
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).
