Selenium, a trace element that is good for the heart
Selenium is an antioxidant trace element that supports the proper functioning of the body. It has also been scientifically established that a diet rich in selenium helps maintain a healthy heart.1
Selenium is an essential mineral: our body does not produce it itself, and therefore we must obtain it through our diet. Even though we only need small amounts of this trace element, it plays a major role in important bodily processes. Furthermore, selenium has an antioxidant effect.1
How does selenium protect cardiovascular health?
It has been proven that a diet rich in selenium has many benefits for the heart. This is mainly due to the antioxidant properties of selenium, which reduce oxidative stress and inflammation in the body.2
In addition, selenium increases the levels of glutathione peroxidase, a molecule that is itself a powerful antioxidant and plays an essential role in protecting cells against peroxides (oxidizing substances) and free radicals.3
Selenium also has other properties:
- it helps protect the heart's mitochondria (which keep our cells healthy) and heart tissue;
- it improves immunity;
- it contributes to thyroid metabolism … All these properties can have a direct or indirect influence on cardiovascular health.4
Please note, even though selenium has so-called ‘cardioprotective’ properties, the intake of selenium alone is not enough to prevent or treat cardiovascular diseases.4
Selenium is good for the heart and, more generally, helps improve our immunity4
