We examined the role of vitamin B status on mortality rates, focusing on cardiovascular disease. Using data from over 12,000 adults, we found that higher scores on the combined vitamin B status indicator (3cB) were linked to lower risks of dying from cardiovascular issues. Specifically, individuals with lower 3cB scores faced significantly higher risks of mortality. This suggests that maintaining adequate vitamin B levels could potentially play an important part in reducing cardiovascular disease-related deaths.

Vitamin B12 reduces cardiovascular risks
We explored the connection between vitamin B12, genetic factors, and cardiovascular health in a group of Chinese adults suffering from hypertension. By analyzing the genetic variations of individuals, we aimed to understand how these may influence levels of homocysteine, an amino acid that can impact heart health when present in high amounts.
Our study included 1,304 participants over the age of 18. We measured their serum levels of vitamin B12 and folate, as well as their total homocysteine concentrations. The findings were quite significant: adequate levels of both vitamin B12 and folate were linked to lower homocysteine levels. This suggests that ensuring proper nutrition might be key to managing cardiovascular risks associated with high homocysteine.
We also noticed that the genotypic effects on homocysteine levels could be lessened with sufficient intake of these vitamins. Targeted nutritional interventions, such as increasing vitamin B12 and folate in the diet, could therefore play an essential role in heart health for those at risk. Our results emphasize the importance of nutrition in supporting cardiovascular health and managing hypertension.

We examined the link between folic acid and vitamin B12 levels and high blood pressure in children and adolescents. Using a nested case-control and cohort study design, we found that those with elevated blood pressure had lower levels of these vitamins compared to control groups. Notably, low folic acid levels were associated with higher blood pressure readings and an imbalance in lipid levels. Our findings highlight the importance of ensuring adequate intake of folic acid and vitamin B12 in childhood, either through diet or supplements, to help regulate blood pressure.

Enhances cardiovascular health
I trust the Now brand. I began supplementing my 83-year-old mother with methylcobalamin after consulting several doctors. It’s recommended for better absorption and aims to support her cardiovascular health, given her limited meat consumption.

We investigated how exposure to metal mixtures during pregnancy influences blood pressure and hypertension later in life.
Using data from Project Viva, we followed 493 women over an average of 18 years.
Our findings revealed that higher levels of vitamin B12, along with essential metals like copper and manganese, were linked to lower blood pressure and reduced hypertension risk.
However, some metals showed mixed results, indicating a complex relationship.
Overall, optimizing nutrient levels during pregnancy may offer lasting benefits for women's cardiovascular health.

We examined a unique case involving a 57-year-old man who experienced a myocardial infarction due to coronary artery spasm. His condition was associated with high serum homocysteine levels and low vitamin B12. Following treatment with vitamin B12 and calcium channel antagonists, his homocysteine levels normalized, and he reported no further chest pain or spasm.
This case suggests that managing homocysteine levels might be an effective strategy in preventing coronary artery spasm, highlighting vitamin B12's potential role in cardiovascular health.

We investigated how blood levels of B vitamins, particularly B6 and B12, influence blood pressure variability (BPV) in individuals with essential hypertension.
Our study included 100 patients with hypertension and 100 healthy controls. We discovered that both B vitamin levels were notably lower in the hypertensive group, while their BPV indices were significantly higher.
Interestingly, those with higher levels of B vitamins showed reduced BPV, suggesting that boosting these vitamins might help manage hypertension. However, while the trend is promising, it doesn't establish a definitive cause-and-effect relationship.

Improves brain health
B-12 is a vital part of my diet. I take it to boost my haemoglobin and relieve muscle pain from myositis. There’s evidence that sufficient B-12 can help prevent diseases like senile dementia and sclerosis in old age. I particularly recommend it for those over 50, dissolving one tablet daily under the tongue to avoid stomach upset.

Lowers homocysteine
I trust Now Foods, so I chose their B-12. The pink cherry-flavoured tablets are delicious and help lower homocysteine, which reduces the risk of heart attacks and strokes. Additionally, B-12 is vital for producing choline, protecting against unbalanced diets and fatty liver disease.
