Vitamin B12 helps heart recoveryVitamin B12 alleviates myocardial ischemia/reperfusion injury via the SIRT3/AMPK signaling pathway.
We explored how vitamin B12 can act as a safeguard against heart damage caused by ischemia/reperfusion (I/R) injury. In our study, we used a mouse model subjected to I/R injury by occluding the left anterior descending coronary artery, followed by 24 hours of reperfusion.
Our aim was to see if high doses of vitamin B12 could improve heart function and reduce damage. Through various evaluations, including echocardiography and biochemical methods, we revealed that vitamin B12 supplementation does indeed help. It mitigates oxidative stress and lowers levels of harmful reactive oxygen species.
Additionally, we found that B12 supplementation reduced cell apoptosis—essentially cell death—in heart tissues. This response was linked to the action of specific signaling pathways, particularly the SIRT3/AMPK pathway. However, we noted that these protective effects diminished when a SIRT3 inhibitor was introduced, indicating the importance of this pathway.
Moreover, RNA sequencing data showed that vitamin B12 also plays a role in reducing inflammation during I/R injury. Overall, our findings suggest that high doses of vitamin B12 might serve as an effective strategy for treating myocardial damage from I/R events, potentially paving the way for new therapies in heart health.

B12 may help heart damageVitamin B12 alleviates myocardial ischemia/reperfusion injury via the SIRT3/AMPK signaling pathway.
We explored the potential of high doses of vitamin B12 to protect against heart damage caused by ischemia/reperfusion injury. By researching mice subjected to heart injury, we found that vitamin B12 showed promising effects in reducing oxidative stress and improving heart function.
Our findings suggest that this vitamin works through specific pathways that lessen inflammation and cell death in heart tissue. However, more studies are needed to fully understand its therapeutic value in treating heart disease.

Cow's milk benefits heart healthCow's Milk Intake and Risk of Coronary Heart Disease in Korean Postmenopausal Women.
We investigated how cow’s milk intake influences the risk of coronary heart disease (CHD) in postmenopausal women. Analyzing data from the Korea National Health and Nutrition Examination Survey, we included 1,825 women aged 50–64.
Our findings indicated that those consuming cow’s milk more frequently (more than three times a week) had better levels of HDL cholesterol and lower CHD risk factors compared to those who did not consume milk.
This suggests that regular cow’s milk consumption could be beneficial for heart health in this group.

B12 may aid Marfan heart healthVitamin B Mitigates Thoracic Aortic Dilation in Marfan Syndrome Mice by Restoring the Canonical TGF-β Pathway.
We investigated how a mixture of vitamins B6, B9, and B12 (VITB) affects heart health in mice with Marfan syndrome. Over 20 weeks, VITB treatment led to reduced heart rate and smaller aorta size in these mice. Notably, VITB helped restore important gene expressions and improved TGF-β signaling, which is crucial for collagen maturation in the aorta. While this study shows promise for VITB in managing heart disease related to Marfan syndrome, further research is needed to confirm its efficacy in humans.

Vitamin B12 may lower inflammationHigher circulating vitamin B12 is associated with lower levels of inflammatory markers in individuals at high cardiovascular risk and in naturally aged mice.
We examined how vitamin B12 levels relate to heart disease risk by looking at inflammatory markers in 136 individuals at high risk. Our findings revealed that those with higher vitamin B12 had lower levels of IL-6 and CRP, both linked to inflammation.
To further validate our results, we studied aged mice and found similar trends. While these observations suggest vitamin B12 might help reduce inflammation, we indicate that further research is needed to fully understand its role in heart disease.
