Vitamin B12 May Lower Alzheimer’s Risk
Vitamin B12 may help to protect people against Alzheimer’s disease, a small study suggests. But other studies in this area have had mixed results. Some have found a link between B12 and Alzheimer’s risk. Others have not. The new study included 271 Finns. They were 65 to 79 years old at the start of the study. At that time, they did not have Alzheimer’s or other dementia. Researchers gave people blood tests. They measured levels of homocysteine, one of the building blocks of proteins. People with high homocysteine levels have a greater risk of stroke. They also measured the active form of B12, which lowers homocysteine levels. During the next 7 years, 17 people developed Alzheimer’s disease. People with higher levels of homocysteine also were more likely to develop Alzheimer’s.
