Low Vitamin K Linked To Cognitive Impairment

With a growing number of studies demonstrating that an optimum supply of micronutrients can aid in the prevention and control of dementia, it is now clear that cognitive decline need not be the inevitable consequence of old age.

Research suggests that B vitamins are particularly important. A recent systematic review found that supplementing with B vitamins, especially folic acid, may have a positive effect on delaying and preventing the risk of cognitive decline.

Other trials have made similar findings. A study published in the American Journal of Clinical Nutrition in 2015 demonstrated that, for participants with high levels of omega-3 fatty acids, a combination of B vitamins prevented brain shrinkage, a hallmark of Alzheimer’s disease.

A review published in 2020 describes how evidence is accumulating that, through taking advantage of their synergistic effects, combinations of antioxidants may be effective not only in preventing Alzheimer’s disease but also in reversing it. Advising combining antioxidant supplements with a nutrient-rich diet, the researchers say such an approach may also be effective against other neurodegenerative diseases.
