vitamin b12 and hypertension

Vitamin B12 is correlated with hypertension to some extent. As a water-soluble vitamin, it is crucial for the nervous system function, red blood cell production, and DNA synthesis. Research indicates that vitamin B12 deficiency could result in elevated homocysteine levels, a risk factor for cardiovascular diseases, suggesting a potential link to hypertension.

In detail, vitamin B12 deficiency may lead to increased homocysteine levels, which can impair vascular endothelial function, raise vascular resistance, and consequently, might result in elevated blood pressure. Moreover, vitamin B12 participates in one-carbon metabolism, a process vital for maintaining vascular health. Thus, vitamin B12 deficiency could impact blood pressure through various mechanisms.

It is important to recognize that while vitamin B12 deficiency may be associated with hypertension, not all individuals with hypertension are deficient in vitamin B12. Additionally, the presence of a deficiency does not guarantee that vitamin B12 supplementation will lower blood pressure. Therefore, individuals with hypertension should have their vitamin B12 levels tested and supplemented under medical supervision, rather than self-administering supplementation without guidance. Concurrently, it is essential for these patients to manage their diet, engage in regular physical activity, and avoid unhealthy habits such as smoking and excessive drinking to mitigate the risks associated with hypertension.
