Vitamin B12 and Cognitive Decline

SOURCE www.foxnews.com
New research suggests that 'normal' levels of vitamin B12 may not be sufficient to prevent cognitive decline and dementia. The study recommends updating current B12 requirements and considering supplementation for older adults, even if their levels fall within normal limits.

Key Points

  • Lower B12 levels linked to slower cognitive processing speeds and brain lesions
  • Current B12 level standards may not account for optimal cognitive function
  • Recommendation for B12 supplementation in older adults with neurological symptoms

Pros

  • Study sheds light on the potential inadequacy of current B12 level standards
  • Recommendation for redefining B12 deficiency criteria for earlier intervention
  • Suggestion for supplementation in older adults to prevent cognitive decline

Cons

  • Need for further research to establish causation between B12 levels and cognitive decline
  • Caution against mega-dosing of vitamins without proper medical guidance
