Sirtmune is a multivitamin and mineral supplement that helps regulate immune function. Scientific research has shown that Nicotinic acid (vitamin B3), zinc, resveratrol and quercetin, which are all found in Sirtmune, help maintain NAD+ levels in our bodies and ensure effective functioning of sirtuins. Sirtuins are a family of 7 proteins found in all mammals, they regulate and control many aspects of our cellular health and immunity. Scientists acknowledge the importance of NAD+ to our cellular health, but it has been shown that the NAD+ levels in our bodies unfortunately decline significantly with age, possibly impacting the effectiveness of our immune systems and making us more vulnerable to illness. The vitamins, minerals and bioflavonoids in SIRTMUNE, may increase our NAD+ levels and activate our sirtuins, which are important for the healthy functioning of our immune systems. Recent evidence suggests that sirtuins (and their activation via NAD+) may also play a role in slowing down ageing and age-related illnesses, neurodegenerative diseases and metabolic diseases such as high blood pressure, type II diabetes, metabolic syndrome and high cholesterol.
