Study Suggests Link Between Blood Homocysteine Levels and Fatigue in Japanese Population

Alinamin Pharmaceutical and Osaka Metropolitan University conducted a joint study on approximately 600 healthy Japanese adults, revealing a significant correlation between blood homocysteine levels—an indicator of vitamin B12 and folate deficiency—and symptoms of fatigue. The findings show that elevated homocysteine concentrations are linked to physical fatigue in men, while in women, they are associated with decreased motivation, anxiety, depression, and reduced cognitive function. This research emphasizes the importance of adequate vitamin B12 and folate intake for managing fatigue and mental well-being.
