Vitaminas B para preservar la memoria

Según un estudio dosis adecuadas de viaminas del grupo B (vean que no son exageradas, especialmente la B6 que ya vimos puede dar problemas en megadosis, sí es alto el ácido fólico) disminuyen la presencia de proteína beta amiloide en la circulación sanguínea, un indicador de senilidad.

Can a person maintain good memory and recall for 115 years? A recent report published in the journal Neurobiology of Aging, documents the case of a 115-year old woman with remarkable preservation of her mental faculties. A more recent report in the same journal points to a simple array of B vitamins (25 mg vitamin B6/pyridoxine, 2000 mcg vitamin B9/folic acid, 400 mcg vitamin B12) which dramatically decreased levels of beta-amyloid in the blood circulation. Beta amyloid is the plaque that builds up in the brain with advancing age that is implicated in Alzheimer's disease. After two years on vitamin therapy, blood levels of beta amyloid only increased by 4.9%, compared to 18.5% in a group received an inactive placebo tablet. Elevated blood levels of beta amyloid is an indicator of the onset of senility. [Neurobiology of Aging 29: 303-06, 2008]
