Insulin-like Growth Factor-1 (IGF-1): An Important Regulator of Growth and Recovery. IGF-1 is a protein similar in structure to insulin. It plays an important role in regulating the growth, development, and renewal of cells and tissues in the body. IGF-1 is the main mediator of growth hormone (somatotropin) action and provides most of its beneficial effects in tissues. In addition, IGF-1 enhances the body's protective properties, reduces oxidative stress and inflammation, slows the development of atherosclerosis, helps restore blood vessels, and promotes the formation of new blood vessels. In the nervous system, IGF-1 promotes axon growth and myelination, has a neuroprotective effect, and prevents age-related decline in cognitive abilities.
The main functions of IGF-1 include:
Strengthening bones, increasing density, reducing bone tissue resorption
Improving amino acid delivery to cells and stimulating protein synthesis in cells, which helps build muscle mass and strength
Reducing inflammation and oxidative stress in the body
Increasing cell sensitivity to insulin
Regulating blood sugar levels
Supporting the growth and restoration of blood vessels
Accelerating skin cell renewal, smoothing wrinkles, and increasing skin elasticity
Increasing resistance to stress
Supporting kidney function
Improving the function of nerve and immune cells
Supporting heart function
Increasing sexual activity and fertility
The use of IGF-1 helps maintain normal weight, activates brain function, improves sleep, increases physical strength, and enhances sexual function.
Furthermore, IGF-1 reduces blood sugar and insulin levels, making it an important component in combating age-related decreases in insulin sensitivity and related aging processes. Research shows that IGF-1 improves the condition of patients with cardiovascular diseases.
When applied topically, IGF-1 provides the following effects:
Antioxidant and restorative action
Anti-aging effect, improved collagen and elastin production
Reduction of wrinkles and prevention of new ones
Regulation of sebaceous gland function and anti-inflammatory action
Help in fighting skin problems (acne, pimples)
