US researchers have found that vitamin B3 reduces levels of a protein related to Alzheimer’s damage in mice.
UK Alzheimer’s charities advise people not to start taking the vitamin before results from human studies.
The vitamin is known as nicotinamide and it is sold in pharmacies and health food shops in UK.
The said vitamin has also shown to help people with diabetic complications and has some anti-inflammatory qualities as well.
The researchers from the University of California at Irvine tested the levels of certain chemicals related to Alzheimer’s disease in engineered mice after giving them the vitamin in drinking water.
The researchers found that levels of phosphorylated tau were quite lower in the animals.
This protein contributes in abnormal ‘deposits’ in brain cells known as ‘tangles’ and lead to the brain damage that gradually affects people with Alzheimer’s.
By utilizing ‘water mazes’ the researchers also found some evidence of enhanced memory in Alzheimer’s as well as unaffected mice.
“Nicotinamide has shown some quite healthy effect on neurons. It proves very effective to prevent loss of cognition in mice with Alzheimer’s. The human testes are progressing and we are moving forward with a clinical trial.” said Dr Kim Green, the lead author of the study.
