PABA
Also known as: para-aminobenzoic acid, "vitamin B10"
PABA is a compound some bacteria use to make folate; it is not a vitamin for humans, although it is sometimes called "vitamin B10". It is sold for hair, skin and greying, but evidence is lacking.
What it is used for
- slowing greying and supporting hair – no reliable evidence
- skin health – no evidence when taken orally
Forms and how they differ
PABA tablets
stand-alone supplement; the human body does not need it as a nutrient
part of B-complexes
content is usually low and without clear benefit
Pairs well with
Not needed on its own; a balanced diet and a B-complex if required.
Do not combine / separate
It may reduce the effect of some sulphonamide antibiotics – if you take them, consult your doctor.
Watch out for
Not suitable in pregnancy or breastfeeding. With liver or kidney disease or when taking medicines, consult your doctor.
Safety
High doses have been linked to nausea, rash and liver injury; do not exceed the label dose.
Practical tip
For hair loss or greying it makes more sense to check iron, B12, thyroid and vitamin D.
