Vitamin A
Vitamin A is a fat-soluble vitamin for vision (especially night vision), immunity, skin and growth. We get it from animal sources (liver, eggs, dairy) and as beta-carotene from plants (carrots, dark vegetables).
| Rating | Range | What it means |
|---|---|---|
| Talk to a doctor | below 1.05 µmol/L | Low vitamin A — diet/absorption. |
| Good | 1.05 – 2.45 µmol/L | Within the reference range. |
| Talk to a doctor | 2.45 µmol/L and above | High — caution (supplements). |
Why it matters
EFSA: both deficiency and excess (supplements) can be harmful.
If it’s low
Low vitamin A can worsen night vision, immunity and skin; here it is rare, more common with malabsorption.
If it’s high
High vitamin A is almost always the result of excessive supplements — it is toxic (headache, liver, fetal damage in pregnancy). Beta-carotene from food is not dangerous.
What to do
For maintenance a varied diet is enough. Do NOT supplement without indication; in pregnancy avoid high doses and liver.
