3. Reduces nerve-harmful compounds
Vitamin B12 helps reduce levels of homocysteine, an amino acid compound that, when elevated, is associated with nerve and vascular damage. High homocysteine levels can contribute to oxidative stress and inflammation, both of which worsen nerve injury and impair healing.
By lowering homocysteine, B12 may protect nerves from further harm and support vascular health, which is important for delivering nutrients and oxygen to nerve tissues. This dual effect underscores why B12 status is critical in managing neuropathy risks.
4. Common deficiency risks
Vitamin B12 deficiency is more prevalent than often recognized, especially in certain populations at higher risk. Adults over age 50, people with diabetes, and individuals on long-term metformin therapy frequently have lower B12 levels due to reduced absorption or dietary intake.
- Older adults often experience decreased stomach acid production, impairing B12 absorption from food.
- People with diabetes may have concurrent gastrointestinal issues or medication effects that limit B12 uptake.
- Vegetarians and vegans are at risk due to the absence of animal-based foods, which are primary B12 sources.
Identifying and treating deficiencies in these groups is essential for preventing neuropathy progression and optimizing nerve health.
