# What to eat for vitamin A deficiency ## Introduction Vitamin A is a fat-soluble nutrient essential for vision, immune function, and epithelial integrity. Deficiency arises from inadequate intake or poor absorption and can impair night vision and increase infection risk. Addressing low vitamin A typically combines dietary changes and, when needed, supervised supplementation. ## 1. Understanding deficiency and supplements Early signs include night blindness, dry eyes, and rough skin, while severe deficiency can threaten vision and immunity. Retinol supplements can correct deficits quickly but carry a toxicity risk, so medical guidance is important. Plant-based beta-carotene offers safer conversion to vitamin A and is appropriate for many people. ## 2. Retinol-rich foods Animal sources with preformed vitamin A include liver, egg yolks, and full-fat dairy, which are highly bioavailable and useful for repletion. Consumption of liver should be occasional due to high vitamin A content, and pregnant people should avoid excess retinol. For practical guidance on food choices and intake, see this detailed resource: [Topvitamine article](https://www.topvitamine.com/blogs/news/what-to-eat-for-vitamin-a-deficiency). ## 3. Beta-carotene sources Plant precursors like carrots, sweet potatoes, pumpkin, and dark leafy greens provide beta-carotene, converted to vitamin A as needed. Cooking and eating these foods with a small amount of fat improves absorption. Smokers should avoid high-dose synthetic beta-carotene supplements due to associated risks. ## 4. Eye health nutrition Vitamin A supports rhodopsin formation and mucosal defenses that protect eyesight; lutein and zeaxanthin from leafy greens add complementary benefits. Combining carotenoid-rich vegetables with modest dietary fat and omega-3s supports ocular health.

Immune boost foods Adequate vitamin A maintains epithelial barriers and supports adaptive immunity, reducing infection vulnerability. Regular intake of colorful fruits and vegetables, fortified foods, and moderate animal sources helps sustain immune function.
