Pterostilben is a type of polyphenol created naturally within the body, but can also be found in almonds, grape leaves, and Vaccinium berries (like blueberries).  We included this ingredient because of research showing its positive effect on lifespan, age-related disease, and health maintenance.   Several studies have found that polyphenols like Pterostilbene and rapamyacin protect against age-related diseases like arthritis, osteoporosis, Alzheimer’s disease, and cardiovascular disease. Pterostilbene has become popular because of its remarkable pharmacological activities, such as anti-tumor, anti-oxidation, anti-inflammation, and neuroprotection.  Pterostilbene can be rapidly absorbed and is widely distributed in tissues, but it does not seriously accumulate in the body.
