Vitamin A (retinol) is essential for ocular surface health, photoreceptor function (rhodopsin synthesis), and epithelial integrity throughout the body. Deficiency is the leading cause of preventable childhood blindness in the developing world and a contributing factor in chronic dry eye and night blindness.<\/p>\n Vitamin A is metabolised to 11-cis-retinal, the chromophore in retinal photoreceptors essential for converting light into nerve signals. It is also required for epithelial cell differentiation, including the conjunctival goblet cells that produce tear-film mucin. Deficiency causes night blindness (rhodopsin failure), Bitot’s spots, conjunctival xerosis, corneal xerosis, and ultimately keratomalacia \u2014 a sight-threatening corneal melt.<\/p>\n Adults: 50,000\u2013200,000 IU once daily for limited deficiency-correction courses (typically 1\u20132 weeks), then maintenance 5,000\u201310,000 IU daily. Children: weight-based dosing under paediatric supervision. Always under medical guidance \u2014 chronic high doses cause hypervitaminosis A.<\/p>\n At therapeutic doses:<\/strong> generally well tolerated.<\/p>\n Hypervitaminosis A (chronic high-dose):<\/strong> headache, nausea, blurred vision, dry skin, cracked lips, alopecia, bone pain, hepatotoxicity, raised intracranial pressure (pseudotumor cerebri).<\/p>\n Acute toxicity:<\/strong> nausea, vomiting, headache, dizziness, blurred vision \u2014 usually resolves within 24\u201348 hours after stopping.<\/p>\n Store at room temperature 15\u201325\u00b0C protected from moisture and light. Keep out of reach of children \u2014 high-dose vitamin A can cause acute toxicity in small bodies.<\/p>\n People with confirmed deficiency (serum retinol or clinical features), xerophthalmia, post-bariatric or post-malabsorption patients, and children in endemic deficiency regions. Most healthy adults on a balanced diet do not need high-dose supplements.<\/p>\n Only if you are deficient. Adding vitamin A to normal levels does not improve night vision and chronic excess causes toxicity (headache, hair loss, bone pain, hepatotoxicity).<\/p>\n No \u2014 therapeutic-dose vitamin A is teratogenic. Routine prenatal vitamins contain low-dose vitamin A or beta-carotene (a safer precursor). Check the label and discuss any supplement with your obstetrician.<\/p>\n The clinical syndrome of vitamin-A-deficiency dry eye \u2014 conjunctival xerosis, Bitot’s spots (foamy patches on the conjunctiva), corneal xerosis, and in severe deficiency keratomalacia (corneal melt). Reversible if treated early.<\/p>\n Vitamin A (retinol) is the active form; beta-carotene is a plant-based precursor that the body converts to vitamin A as needed. Beta-carotene cannot cause hypervitaminosis A \u2014 the body regulates conversion. Beta-carotene supplements are safer in pregnancy and chronic use.<\/p>\n Vitamin A is stored in the liver. Cirrhosis or any chronic liver disease increases toxicity risk. Routine high-dose supplementation is contraindicated. Mild deficiency can be addressed with dietary measures (orange and dark-green vegetables, dairy, eggs) plus low-dose multivitamins.<\/p>\n Some studies suggest high-dose vitamin A palmitate (15,000 IU\/day) may slow progression in adult-onset retinitis pigmentosa, but the evidence is mixed. This is not the same as treating routine night blindness. Discuss with a retinal specialist.<\/p>\n Beta-carotene supplements (and possibly high-dose vitamin A) have been linked to increased lung cancer risk in smokers (CARET, ATBC trials). Smokers should avoid high-dose vitamin A and beta-carotene.<\/p>\n Only under paediatric guidance. Children are particularly susceptible to acute and chronic toxicity. WHO recommends specific doses for measles in children in endemic regions.<\/p>\n Check the total vitamin A content across all your supplements. Most multivitamins contain 2,500\u20135,000 IU. Adding Vitamin A Chewable Tablet on top can quickly exceed safe upper limits with chronic use.<\/p>\n <\/p>\n Kunder, der ser dette produkt, overvejer ogs\u00e5 disse alternativer i vores \u00d8jensundhed<\/a> sortiment:<\/p>\n Informationen p\u00e5 denne side er kun til undervisningsform\u00e5l og er ikke en erstatning for medicinsk r\u00e5dgivning fra en kvalificeret \u00f8jenl\u00e6ge eller optiker. \u00d8jenlidelser kan hurtigt true synet \u2014 pludseligt synstab, st\u00e6rke smerter eller trauma er en akut \u00f8jenl\u00e6gehj\u00e6lp.
