It is the ideal complement to strengthen the immune system, maintaining health, well-being and quality of life. Science has shown that with age, the immune system becomes ineffective: The immune system loses the ability to detect invading elements and destroy them. As a consequence, infections are more frequent and serious. Macrophages (the first defensive barrier) lose the ability to engulf and destroy viruses, bacteria, cancer cells and foreign bodies. T lymphocytes respond in fewer, late, and poorly to antigens, with the added risk of hyperimmune or autoimmune reactions with hyperreactivity of B lymphocytes. All these processes explain why pneumonia, influenza, viral infections, infective endocarditis and many pathologies are more common in advanced ages and can be fatal. The senescence of the immune system is the main cause of cancer, infections and degenerative pathologies such as Alzheimer's that appear with age. Excelvit strengthens the immune system response so that it acts more efficiently by increasing the phagocytosis capacity of white blood cells and rapidly returning to equilibrium without generating an aggressive response. Take 2-4 capsules a day or as recommended by an expert. Keep in a cool, dry place and protected from sunlight.
