Your vitamin A level is in the normal range, supporting healthy vision, immune function, skin integrity, and cell differentiation.
Very low vitamin A is a medical emergency in the developing world and increasingly seen in malabsorption disorders. Without vitamin A, night vision fails first, followed by permanent blindness (xerophthalmia). The immune system also collapses — infections become life-threatening.
Seek urgent medical care. High-dose vitamin A supplementation under medical supervision is needed. Identify the cause — fat malabsorption disorders (Crohn's, celiac, cystic fibrosis) are common may contribute to.
Vitamin A: {{value}} {{unit}} — very low (ref: {{low}}–{{high}})Low vitamin A impairs night vision (night blindness is one of the first signs), reduces immune function, may contribute to dry eyes and skin, and impairs the integrity of mucous membranes throughout the body. Fat malabsorption disorders are a common cause.
Increase dietary vitamin A from liver, oily fish, eggs, and dairy. Beta-carotene from orange vegetables is converted to vitamin A in the body. See your doctor if malabsorption is suspected.
Vitamin A: {{value}} {{unit}} — below reference range (ref: {{low}}–{{high}})Borderline low vitamin A can cause dry eyes (xerophthalmia), dry skin, and slightly reduced immune resilience. It's most often dietary.
Increase intake of vitamin A-rich foods: liver, egg yolks, dairy, and orange/yellow vegetables. Ensure adequate fat intake for absorption.
Vitamin A: {{value}} {{unit}} — borderline lowYour vitamin A level is in the normal range, supporting healthy vision, immune function, skin integrity, and cell differentiation.
No action needed. Continue a balanced diet with vitamin A-rich foods.
Vitamin A: {{value}} {{unit}} — within reference rangeYour vitamin A is right in the healthy midrange, supporting excellent visual acuity, robust immune function, and healthy skin cell turnover.
No action needed. Good result.
Vitamin A: {{value}} {{unit}} — optimalBorderline high vitamin A is most often caused by over-supplementation with preformed vitamin A (retinol). Unlike beta-carotene, preformed vitamin A is fat-soluble and accumulates in the liver.
Review supplement doses. Avoid taking more than 3,000 mcg (10,000 IU) of preformed vitamin A daily without medical guidance. Beta-carotene (vegetable sources) is much safer as the body regulates its conversion.
Vitamin A: {{value}} {{unit}} — borderline highHigh vitamin A may contribute to hypervitaminosis A — nausea, headache, dizziness, blurred vision, liver damage, and paradoxically hair loss and skin problems. Bone loss and increased fracture risk also occur with chronic excess.
Stop vitamin A supplements immediately. Avoid liver and liver-containing products temporarily. See your doctor to assess for liver effects.
Vitamin A: {{value}} {{unit}} — above reference range (ref: {{low}}–{{high}})At this level, acute vitamin A toxicity is present. Symptoms include noticeable headache, intracranial pressure elevation (pseudotumor cerebri), liver damage, bone pain, and fetal defects in pregnant women. This needs urgent medical attention.
Seek medical care immediately. Stop all vitamin A supplementation. Liver function testing and neurological evaluation are needed urgently.
