Currently, there are several medical studies and reports suggesting that spirulina (Arthrospira maxima and Arthrospira platensis) could serve as a preventive method for cardiovascular diseases. Within the studies carried out with Spirulina there are a large variety of results, advanced or preliminary, that develop the effects on the concentration of plasma lipids and related to blood pressure. In addition, the different effects on diets through Spirulina that were tested in animals of normal size or obese, relating the vasomotor reactivity that have the rings of the aorta. In all cases, the results obtained revealed a very close relationship between the consumption of Spirulina and the increase in the synthesis and release of nitric oxide, a very strong antioxidant created by the body, by the endothelium (blood vessel wall).
In addition to this, there was an increase in the synthesis and release of many vasodilators that are highly active, as well as a decrease in the synthesis and release of vasoconstrictors within the endothelium. Indirectly, it also modifies the total cholesterol and high-density lipoprotein values, known as HDL or "good" cholesterol. It is important to note that the intake of different antioxidants, such as type C and E vitamins, coenzyme Q10 and natural plant substances known as flavonoids (natural plant substances that are present in different species), substantially improves the above because each of these components stops the oxidative processes responsible for the deterioration of the walls of veins and arteries. In addition, they are also able to produce a greater amount of nitric oxide within the body.
