A vitamin essential to vision and mucous-membrane health, used short-term for certain eye conditions.
📊 How it ranks (our editor score) — 45/100Tap to see the breakdown
🌱 What it is
Vitamin A is an essential nutrient needed for vision, immune function, and healthy skin and mucous membranes; beta-carotene is a plant-based precursor the body converts as needed.
✨ Why it's good for you
- Supports healthy vision, especially in low light
- Maintains healthy cornea and mucous membranes
- Beta-carotene form has a wide safety margin
🥄 How to use it
For eye-related conditions, some use up to 10,000 IU daily briefly under medical guidance; beta-carotene is the gentler, preferred form for most people since the body regulates its conversion.
How much: Up to 10,000 IU daily briefly (prefer beta-carotene form); do not exceed 10,000 IU/day if pregnant.
Why it works: Vitamin A is needed to make visual purple (rhodopsin) for night vision and to maintain the cornea and mucous membranes; deficiency can cause night blindness and dry eye tissue.
⚠️ Cautions
- Preformed vitamin A in high amounts can be dangerous — limit to 10,000 IU or less if pregnant, since excess is linked to birth defects.
- Long-term high-dose preformed vitamin A can cause liver toxicity; do not exceed recommended amounts without medical supervision.
- See an eye doctor for any of these conditions to confirm the diagnosis before self-treating.
