Primarily investigated for inherited retinal diseases such as retinitis pigmentosa and Leber congenital amaurosis. Also used as a dietary supplement to support overall eye health and as a source of vitamin A for individuals with deficiency states.
Beta-Carotene (9z)- is converted in the body to 11-cis-retinol, a critical component of the visual cycle. It acts as a precursor to vitamin A, which is necessary for the production of rhodopsin in rod cells of the retina, supporting low-light and peripheral vision.
High-dose vitamin A can be toxic; beta-carotene offers a safer alternative as it converts to vitamin A only as needed. Smokers should exercise caution with beta-carotene supplements as some studies suggest increased risk with heavy smoking. Pregnant women should consult their healthcare provider before use.
