Recent study results suggest that taking a high-dose vitamin B1 supplement each day may help diabetics reduce their risk of kidney damage.

Diabetic nephropathy, or kidney disease, is a common complication of type 2 diabetes. An early indicator of kidney disease is microalbuminuria, where the kidney leaks albumin into the urine.

New research examined whether vitamin B1 would effect microalbuminuria and the results sugest it can reverse the onset of early diabetic kidney disease.

In the trial type 2 diabetics were given 300 milligrams of vitamin B1 (thiamine) each day for three months. Results showed that the vitamin supplement reduced the rate of albumin excretion by 41%. Furthermore, 35% of patients with microalbuminuria saw their urine albumin excretion return to normal after being treated with the vitamin.
