Longitudinal studies showed that people with type 2 diabetes taking metformin lived 15 percent longer than healthy controls not taking the drug. This raises the question as to whether the longevity benefits of metformin may extend to healthy people. However, metformin may inhibit exercise-induced benefits, such as cardiorespiratory fitness and gains in lean body mass. In this clip, Dr. Rhonda Patrick gives her thoughts on whether healthy, active adults should take metformin.
Important for the endocrine enhancing properties of exercise. Exerkines are exercise-induced hormonal-like factors which mediate the systemic benefits of exercise through autocrine, paracrine, and/or endocrine properties.[1]

A drug commonly used for the treatment of type 2 diabetes. Metformin is in a class of antihyperglycemic drugs called biguanides. It works by decreasing gluconeogenesis in the liver, reducing the amount of sugar absorbed in the gut, and increasing insulin sensitivity. A growing body of evidence indicates that metformin modulates the aging processes to improve healthspan and extend lifespan. Furthermore, metformin may prevent genomic instability by scavenging reactive oxygen species, increasing the activities of antioxidant enzymes, inhibiting macrophage recruitment and inflammatory responses, and stimulating DNA damage responses and DNA repair.[1]

A metabolic disorder characterized by high blood sugar and insulin resistance. Type 2 diabetes is a progressive condition and is typically associated with overweight and low physical activity. Common symptoms include increased thirst, frequent urination, unexplained weight loss, increased hunger, fatigue, and impaired healing. Long-term complications from poorly controlled type 2 diabetes include heart disease, stroke, diabetic retinopathy (and subsequent blindness), kidney failure, and diminished peripheral blood flow which may lead to amputations.
