High vitamin B3 risk of heart disease (high doses of niacin can cause heart disease)

A study on vitamin B was recently published in Nature Medicine. A study found that high levels of vitamin B can cause several types of heart disease. A strong association was found between vitamin B3 and the risk of developing a heart attack, stroke, or other serious cardiovascular event (niacin and heart disease risk).
Researchers at the US National Institutes of Health have found that too much niacin can directly affect heart health by stimulating inflammation. This causes the walls of the blood vessels to become thicker. This thickening restricts blood flow. It can damage tissues and organs, including the heart.

Some fortified foods, such as flour and cereals, contain niacin. Most people do not need to take niacin supplements because they get enough from food.

How Does Niacin Affect Heart Health?

The researchers wanted to find markers in the blood that could reveal new risk factors for heart disease. For this, blood samples of 1,162 patients were analyzed. 4PY (4PY-pyrophosphate) was detected in some blood samples. It is a substance that is produced only when there is an excess of niacin.

They found that people with 4PY in their blood were less likely to have a heart attack, stroke, or other adverse cardiovascular event. People who consume large amounts of alcohol may develop a niacin or vitamin B3 deficiency.
