B Vitamins Can Slow Down Brain Aging

According to a recent Oxford study, published in the journal Neurology [1], found that vitamin B12 may slow down the rate at which brain cells die in older people.

Researchers showed that people who had higher vitamin B12 levels in the blood were six times less likely to experience brain shrinkage compared with those who had lower levels of the vitamin. None of the people in the study had vitamin B12 deficiency.

The study involved 107 people between the ages of 61 and 87. They underwent brain scans, memory testing and physical exams, and blood samples were also collected to check vitamin B12 levels. Brain scans and memory tests were performed again five years later.

This is great news for Entropy consumers, who get the benefit of 100 µg of vitamin B12 per serving -- the highest among popular energy drinks. We already knew that B12 was a great vitamin for brain function, mood levels and was correlated with cognition and memory scores [2,3]. That's why we put it there in the first place. Now we know it may protect brain cells from the effects of aging too.
