Introduction
, which are in a similar category to HGH supplements, work by increasing the production of insulin-like growth factor in the body.
IGF-1 is similar in structure to insulin, hence the name insulin-like growth factor.
Part of a group of peptides known as somatomedins, IGF-1 is an endocrine hormone that’s mainly produced by the liver and regulates much of the growth-promoting effects of HGH.
In simple terms, human growth hormone (HGH) signals the liver to produce IGF-1, which stimulates cell growth, healing, and development throughout the body.
Normally, IGF-1 production reaches it’s peak during adolescent and pubescence, rapidly decreasing during adulthood.
Significant benefits, however, can be achieved by adults who increase IGF-1 levels by using over-the-counter IGF-1 supplements.
IGF-1 supplements encourage the body to increase it’s own production of IGF-1 which can lead to heightened cell growth and development, healing, strengthening of the tissues, and a wide variety of other “anti-aging” benefits, including:
- An increase in lean muscle mass
- Faster metabolism and fat burning
- Strength and endurance gains
- A stronger immune system
- Speedier recovery and healing time
- An increased sex drive
- Better cognitive function
The ingredients found in IGF-1 supplements are often similar to those found in HGH products. One common ingredient used for raising IGF-1 levels is deer antler velvet.
Once banned by the World Anti-Doping Agency, deer antler velvet contains several important growth factor components, including IGF-1.
Not surprisingly, deer antler velvet is a popular choice among professional athletes.
