Growth Hormone and Aging

     Injections of growth hormone have long been a staple of anti-aging therapy. A recent study found that people in their 90's with naturally low levels of growth hormone appear to have a far better chance of living into the 100's. The lesson here might be that we ought to optimize nutritional intake and leave hormone manipulation to the inherent wisdom of the body if at all possible.

Growth Hormone

     One of the hottest areas of supplementation in anti-aging research of the use of growth hormone. An older study showed that growth hormone aided weight loss and made the skin tighter. This was equated with reversing aging.
     A recent study suggests that growth hormone may not be a great contributor to a longer life. The hormone increases insulin-like growth factor-1 (IGF-1). A recent study suggests that elevated IGF-1 levels may increase risk of cancer and decrease lifespan.
     Sales of growth hormone totaled 3.5 billion dollars in 2011. Those who are spending their money in this way may be receiving no benefit. The use of supplementing with hormones is fraught with risks and unintended consequences.
