Vitamin A and beta carotene are essential for maintaining the integrity of the cornea and the light-sensing pigments in the retina, so deficiency greatly increases the risk of night blindness and other ocular pathologies. In vitamin A deficient regions, hundreds of thousands of children each year develop xerophthalmia, ranging from conjunctival and corneal dryness to corneal ulceration and keratomalacia, which can progress to irreversible blindness if not corrected. Even subclinical deficiency can impair dark adaptation and increase susceptibility to eye infections, making adequate vitamin A and carotenoid intake a critical foundation for long-term visual health. This medication is commonly used for High Cholesterol.

Bile acid sequestrants work by binding to cholesterol and bile acids in the intestine, unfortunately, they can also bind to fat soluble vitamins like vitamin D3, hindering its uptake into the bloodstream. For individuals taking bile acid sequestrants, supplementing with vitamin D3 may be advisable to prevent or address potential deficiencies.
