b12 herzgesundheit

Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a crucial role in the functioning of the nervous system, the formation of red blood cells, and the metabolism of every cell in the body. In addition to these important functions, B12 has also been linked to heart health.

Vitamin B12 and Homocysteine Levels

High levels of homocysteine, an amino acid in the blood, have been associated with an increased risk of cardiovascular disease. Vitamin B12, along with vitamin B6 and folate, helps in the breakdown of homocysteine, thus reducing the risk of heart disease.

Vitamin B12 and Blood Pressure

Studies have shown that individuals with lower levels of vitamin B12 are more likely to have higher blood pressure. B12 helps in the production of red blood cells, which carry oxygen to the body’s tissues, including the heart. This, in turn, can help in maintaining healthy blood pressure levels.

Deficiency of Vitamin B12 and Heart Health

A deficiency in vitamin B12 can lead to anemia, a condition characterized by a lack of healthy red blood cells. Anemia can lead to fatigue and weakness, which can put added stress on the heart. Over time, this can lead to heart problems.

Sources of Vitamin B12

Vitamin B12 is naturally found in animal products such as meat, fish, eggs, and dairy products. For individuals following a vegan or vegetarian diet, fortified foods or supplements may be necessary to meet their B12 requirements.


From maintaining healthy homocysteine levels to regulating blood pressure, vitamin B12 plays a critical role in heart health. It is important to ensure an adequate intake of B12 through a balanced diet or supplementation, especially for individuals at risk of deficiency. By doing so, one can help reduce the risk of cardiovascular disease and promote overall heart health.
