IGF-1 Levels and the Aging Process

“product By Michael 7 years ago

Multiple studies have confirmed that declining levels of IGF-1 play a key role in the negative effects associated with the aging process, including a decrease in lean muscle mass and an increase in adipose (fat) tissue. One particular study conducted on 21 healthy men aged 61 to 81 years only provides further support for the notion that low IGF-1 levels in the body are strongly correlated with an increase in aging’s adverse effects.

In the study, the men were divided into two groups; one group received IGF-1 treatment three times weekly for six months while the control group received no treatment. By the end of the study, the effects on the group that received treatment were as pronounced as they were convincing. This group saw an average increase in lean muscle mass of 8.8% along with a 14.4% decrease in adipose tissue. Additionally, the group receiving treatment experienced an average increase of 1.6% in lumbar vertebral bone density along with a 7.1% average increase in skin thickness (thinning of the skin and certain bones is a significant effect of the aging process). Conversely, the control group receiving no treatment saw no change in muscle mass, adiposity, bone density, or skin thickness.

Studies such as this abound and only further reinforce the critical role IGF-1 plays in the body. Importantly, IGF-1 LR3 is considered to be 2-3 times more efficacious than unaltered IGF-1 in achieving these effects.
