High doses of B vitamins can halve the pathological brain shrinkage in older adults that often precedes dementia and Alzheimer’s disease, reports the Public Library of Science One.
Brain loss is one of the symptoms of mild cognitive impairment (MCI) that often precedes dementia.
Researchers from the Oxford Project to investigate Memory and Aging (Optima) observed 168 elderly people with mild cognitive impairment – slight memory loss and language problems. These disorders were greater than would be expected at a similar age, indicating that they could worsen and progress to Alzheimer’s disease or other forms of dementia.
Half of the volunteers were given a daily tablet containing significantly more folic acid, vitamins B6 and B12 than the recommended daily dose. The rest were given a placebo, i.e. tablets with no pharmacological effect of a similar appearance. After two years, the degree of brain atrophy was measured.
After the age of 60, the average brain shrinks by 0,5%. annually. In mild cognitive impairment, the decline is twice as fast, and in Alzheimer’s disease it accelerates to 2,5%. annually. As it turned out, the administration of vitamin B slowed the decline by 30%, and in some cases by as much as 50%. – to the level of people with no cognitive impairment.
B vitamins (folic acid, vitamin B6 and B12) lower the level of homocysteine in the blood. It is known that homocysteine is associated with faster brain atrophy and Alzheimer’s disease – and this mechanism explains the results, although they are surprised by such a strong effect of administering ordinary vitamins.
The daily, recommended dose of vitamin B can be delivered to the body with the help of appropriate supplementation. The Do.Best brand offers the high-quality Do! Active dietary supplement, which you can buy today at medonetmarket.pl at a very attractive price. We also recommend High Five B-Complex Viridian, which can be purchased in packages of 30 or 120 capsules.
Continuation of research is to show whether Alzheimer’s disease can be prevented in this way. At the same time, scientists warn against taking very high doses of vitamins without consulting a doctor (PAP).
