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 Clien\u021bii care vizualizeaz\u0103 acest produs iau \u00een considerare \u0219i aceste alternative din gama noastr\u0103 \u00cengrijirea ochilor<\/a> de:<\/p>\n Informa\u021biile de pe aceast\u0103 pagin\u0103 au scop educa\u021bional \u0219i nu \u00eenlocuiesc sfatul medical al unui oftalmolog sau optometrist calificat.
