Vitamin D boosts brain

There is more evidence that vitamin D keeps the brain in good working order, with the latest British research finding a link with better memory.

A study of more than 3000 men aged 40 to79 assessed their mental agility using a range of tests, while blood samples measured vitamin levels.

The study found those with high vitamin D levels performed better on memory and information processing tests, while those who had the lowest levels – 35 nmol/litre or under – registering poor scores, said the Journal of Neurology Neurosurgery and Psychiatry.

They said vitamin D – found in fish and produced by sun exposure – could protect cells or key signalling pathways in the brain.
