Vitamin therapy 'could still cut stroke risk'

Vitamin therapy still has a role to play in reducing the brain injury seen in stroke, one academic has argued.

Doctors once used vitamin B therapy as a standard treatment to lower homocysteine levels, as too much of the amino acid in the bloodstream had been linked to increased risk of stroke and heart attack.

However, several randomised trials revealed that lowering homocysteine levels with vitamin B did not have any cardiovascular benefit.

More recently, a study by Dr David Spence of the University of Western Ontario revealed that vitamin B therapy could actually increase cardiovascular risk in patients with diabetic nephropathy.

He commented that scientists have overlooked the key role of vitamin B12 and the recently recognised role of renal failure in cardiovascular conditions.

"It is now clear that the large trials showing no benefit of vitamin therapy obscured the benefit of vitamin therapy because they lumped together patients with renal failure and those with good renal function," Dr Spence noted.

"The vitamins are harmful in renal failure, and beneficial in patients with good renal function, and they cancel each other out."
