News MedicalNew Research Unveils Vast Influence of B Vitamins on Health and Disease

This review article explores current evidence on the roles of B vitamins, particularly B12 and folate, in cognitive health, dementia, cardiovascular disease, and inflammation. The authors, who are expert researchers in B vitamin nutrition, present key findings and identify areas needing further study to guide clinical practice.

⚕️ Key Clinical Considerations ⚕️

• Vitamin B12 deficiency is underdiagnosed in older adults and may contribute to cognitive decline
• Standard B12 tests are inadequate; MMA and homocysteine levels should also be checked
• Elevated homocysteine predicts brain atrophy and dementia risk
• B vitamin supplementation can slow brain shrinkage and cognitive decline in at-risk individuals
• High folate levels may exacerbate B12 deficiency cognitive effects

🎯 Clinical Practice Impact 🎯

• Patient Communication: Educate on importance of B12 for brain health, especially after age 75
• Practice Integration: Include MMA and homocysteine with B12 testing in older adults
• Risk Management: Identify and treat B12 deficiency early to reduce dementia risk
• Action Items: Consider B vitamin supplementation in at-risk patients, monitor B12 and folate balance
