High blood pressure is a major health issue all over the world and controlling it can be difficult for many people.
Now, new research from the University of Maine and other institutions suggests that vitamin B may offer a helpful, natural way to manage this condition.
The study found that lowering a substance in the body called homocysteine—by using certain B vitamins—can help reduce blood pressure. This could be especially helpful for people whose blood pressure stays high even when they take several medications.
Around 12.8% of people worldwide have what’s known as drug-resistant high blood pressure. This means their blood pressure remains too high despite trying multiple medicines. Doctors aim to lower blood pressure to below 140/90 mmHg, but new guidelines now suggest an even lower target of 130/80 mmHg, which makes it harder to control.
This is where homocysteine comes in. Homocysteine is a natural substance made by the body, and it’s involved in how we use vitamins. When homocysteine levels are too high, it usually means the body lacks important B vitamins like B6, B12, folate, or riboflavin (B2).
It can also be due to a gene issue. High homocysteine levels can cause blood vessels to narrow, which raises blood pressure and increases the risk of other health problems.
The researchers looked at many earlier studies and found that taking enough B vitamins from supplements—not just from food—can lower blood pressure by around 6 to 13 mmHg. That’s a big improvement for people who haven’t had success with regular treatments. And it’s safe when done under medical care.
However, there is some disagreement about what counts as a normal homocysteine level. Many labs say that up to 11.4 μmol/L is fine, but some experts think the level should be lower—10 μmol/L or less. This difference suggests that labs may need to update their standards.
The good news is that taking B vitamins might offer an affordable, simple way to help control drug-resistant high blood pressure. But it’s important to remember that this kind of treatment should always be done under the care of a doctor. Taking the wrong dose or skipping regular check-ups could lead to problems.
The scientists behind the study believe that adding B vitamins to standard drug treatment could make a real difference for people struggling with high blood pressure that won’t go down.
In conclusion, this study gives hope to many people dealing with hard-to-treat high blood pressure. Using vitamin B to lower homocysteine levels might be an effective, natural, and safe addition to other treatments.
As doctors learn more, we may see vitamin-based therapies become part of regular care. But, as always, medical advice and supervision are key to staying safe and healthy.
