Scientists at the University of Salerno in Italy found that supplementing with spirulina, a biomass derived from blue-green algae, can improve blood sugar control and reduce “bad” cholesterol levels in the body. Research results published In the nutrition magazine.
The study by Italian researchers is a review of previous scientific studies on the beneficial properties of spirulina. They focused on evaluating the effect of this dietary supplement on blood sugar and cholesterol levels.
The review found that spirulina has the ability to reduce blood sugar concentrations, thereby preventing the development of cardiovascular diseases. The mechanism by which spirulina improves blood sugar control is not yet fully understood. Scientists suggest that this substance may affect insulin secretion by β cells in the islets of Langerhans in the pancreas and facilitate the transport of glucose from the blood to all peripheral tissues.
It is also stated that spirulina can reduce the concentration of low-density lipoproteins (LDL) in the body. Low-density lipoproteins, which carry cholesterol molecules in the bloodstream, are considered “bad” because they have the ability to form plaque by settling on the walls of blood vessels. Moreover, this positive effect is not dose dependent; The supplement is safe and non-toxic, even at high doses.
The scientists added that the question of the optimal amount of spirulina consumed daily is still unanswered. According to them, the dosage and timing of the supplement should be standardized to achieve the maximum positive effect.
