IGF-1: How Does It Work?

IGF-1: How Does It Work?

Nutronics Labs |

IGF-1, or Insulin-like Growth Factor 1, is a crucial hormone for the body's growth and development. Often associated with muscle growth and repair, IGF-1 is essential for overall health and vitality. In this blog, we explore how IGF-1 works, sources in the body, and the benefits of natural supplements.

How Does IGF-1 Work?

IGF-1 operates through an intricate system involving interactions with other hormones. To understand how IGF-1 works to help our bodies grow and stay healthy, we need to break down the cellular and molecular processes it influences.

Binding to IGF-1 Receptors

The first step in IGF-1's action is binding to specific receptors on the surface of cells, known as IGF-1 receptors. These receptors are widely distributed throughout the body, particularly in tissues involved in growth and development, such as muscles, bones, and the liver. When IGF-1 binds to these receptors, it leads to various physiological effects.

Signaling Pathways: The Communication Network

Once IGF-1 unlocks the receptor, it creates a chain reaction inside the cell, like turning on a series of switches communicating messages. There are two main pathways, or communication routes, that get activated:

PI3K/Akt Pathway

This pathway is like a master switch for cell growth and survival. When turned on, it tells the cell to start making more proteins and grow bigger. It also helps prevent the cell from dying prematurely. Cell death is a natural process known as apoptosis. This process is especially important for muscle cells, as it helps them grow stronger and repair themselves after exercise or injury, contributing to muscle mass gains.

MAPK Pathway

This pathway helps cells decide when to divide and create new cells. It sends messages to the cell's nucleus (the control center) to activate genes that promote cell growth and repair. This pathway is vital for bone growth and healing, as it helps produce new bone cells.

Interaction with Other Hormones

IGF-1 does not act in isolation; it interacts with other hormones, particularly growth hormone (GH) and insulin. Growth hormone stimulates the production of IGF-1 in the liver and other tissues. 

Growth Hormone (GH)

The pituitary gland releases GH and stimulates the liver to produce IGF-1. IGF-1, in turn, mediates many of the growth-promoting effects of GH. This ensures that the body grows and develops appropriately during childhood and adolescence.


IGF-1 shares structural similarities with insulin and can somewhat interact with insulin receptors. This interaction helps regulate glucose metabolism and improves insulin's anabolic (building up) effects on tissues like muscle and fat.

Cellular Effects

Cell Growth and Proliferation

IGF-1 promotes cell growth and division, contributing to tissue development and repair. This is particularly important in muscles, bones, and other tissues that require regular renewal and regeneration.

Protein Synthesis

IGF-1 regulates the synthesis of proteins – the building blocks of cells and tissues. This is critical for muscle growth and repair and for maintaining overall tissue health.

Inhibition of Apoptosis

IGF-1 helps protect cells from programmed cell death (apoptosis), so tissues can grow and regenerate effectively.

Metabolism Regulation

By interacting with insulin and other metabolic pathways, IGF-1 helps regulate glucose and lipid metabolism, contributing to overall metabolic health and energy balance.

In simple terms, IGF-1 is like a master controller that helps our cells grow, repair, and stay healthy. It works by unlocking receptors on cells, activating important communication networks inside the cells, and teaming up with other hormones to regulate growth and metabolism. This makes IGF-1 an essential player in maintaining our overall health and vitality.

Summarized Role of IGF-1 in the Body

IGF-1 drives physical growth during childhood and adolescence and is key to muscle hypertrophy and recovery after exercise or injury. IGF-1 promotes cell regeneration, contributing to anti-aging effects, and helps regulate fat metabolism, influencing body composition.

Sources of IGF-1

IGF-1 is naturally produced in the liver but can also be acquired through dietary sources and supplementation. The body produces IGF-1 in response to growth hormone stimulation. Foods rich in protein can boost IGF-1 levels, but supplements like our IGF-1 sprays, offer a more direct source. Our high-quality supplements are derived from ethically sourced deer antler velvet because of its rich IGF-1 content.

IGF-1 Supplementation

IGF-1 supplements are used for various reasons. Athletes and fitness enthusiasts often use IGF-1 to improve performance and speed up recovery. Available from Nutronics Labs as an oral spray or capsule, IGF-1 supplements are considered safe when used correctly. Consult with a healthcare provider before use and follow all dosage recommendations to get the best results.
