New Research Shows Vitamin B12 May Hold the Key to Healthy Aging

Cornell researchers found new links between vitamin B12 and muscle energy production, lipid metabolism, and cellular stress pathways.

Mouse and cell-model evidence suggests low B12 may weaken muscle maintenance, while supplementation may support mitochondrial function.

The findings imply B12 could play a bigger role in healthy aging, muscle function, and disease risk than previously thought.

The study may also help improve screening for nutritional stress and guide more precise supplement advice, especially for older adults.
