High blood pressure, or hypertension, is a widespread health concern affecting millions of people globally. While medications are available, about 12.8% of those with high blood pressure still can’t control it, a condition known as drug-resistant hypertension.
Health guidelines now recommend maintaining blood pressure below 130/80 instead of the previous 140/90 to reduce health risks. This shift highlights the importance of finding more effective ways to manage blood pressure levels.
One possible factor in hypertension is a substance in the body called homocysteine. Normally, homocysteine interacts with certain vitamins—such as B6, B12, folate, and B2—to stay at a healthy level.
If someone lacks these vitamins, homocysteine can build up. High levels of homocysteine can narrow blood vessels, increasing blood pressure and potentially leading to other health problems.
Scientists at the University of Maine, led by Merrill Elias, explored whether increasing B vitamin intake could help manage blood pressure.
Their research showed that B vitamin supplements could lower homocysteine levels, which in turn, might reduce blood pressure. Since B vitamins are affordable, this could offer a cost-effective way to support those struggling with hypertension.
To better understand how well this approach might work, the researchers looked at data from multiple studies.
They found that taking B vitamins could reduce blood pressure by 6 to 13 points on average. This means that someone with a blood pressure of 140 might see it drop to around 127—a significant improvement.
There’s some debate, however, over what the ideal homocysteine level should be for optimal health. While many agree it should stay below 10, some argue it could be acceptable up to 11.4.
The Maine researchers suggest that keeping homocysteine levels even lower could be best for overall health.
For people who have difficulty managing their blood pressure with medication alone, B vitamins might be an additional tool in their treatment plan.
However, it’s essential to consult a healthcare provider before starting any new supplements to ensure they are safe and appropriate.
The findings of this research were published in the American Journal of Hypertension, sparking interest in the role of B vitamins as a potential support for managing high blood pressure.
