Insulin-like growth factor-1 is manufactured in the liver. It’s a type of growth hormone whose production and synthesis is triggered by growth hormone, produced in the pituitary gland. A polypeptide hormone, IGF-1 is described as a chain of peptides that form the foundation of protein synthesis.
The main responsibility of it is to stimulate cellular growth. It’s also involved in regulating the effect of growth hormone in the body. It binds to receptors of specific cells. This function initiates a number of activities and functions.
Because IGF-1 makes things grow, including muscles, it’s long been a favorite of bodybuilders because of its ability to enhance an anabolic environment, increase the production of protein, and retain nitrogen.
What does nitrogen have to do with muscular growth or bodybuilding? Without protein, muscle tissue cannot grow, nor can a number of other tissues in the body. Because they’re formed of amino acids, proteins rely on the non-essential amino acids produced in the liver. Essential amino acids are generally obtained through diet.
Non-essential amino acids are produced in the body. A careful balance of essential and non-essential amino acids is required for muscle production.
Macronutrients (carbohydrates, proteins, and fats) contain oxygen, hydrogen, and carbon. However, proteins also contains one additional component – nitrogen. When it comes to bodybuilding, a positive nitrogen balance is important for muscle growth. Negative nitrogen balances can ultimately cause damage to muscle tissues as well as other body tissues.
IGF-1 also affects numerous functions of other endocrine glands and a number of metabolic processes, including the metabolism of fats and lipids. It has also been increasingly studied for its potential in healing wounds, promoting the development of collagen and in the repair of cartilage tissues. It’s also been studied for its possible potential to increase the production of neurons in the brain.
While insulin-like growth factors provide numerous benefits, IGF-1 is most popular among bodybuilders because of its potential to speed recovery processes involving injured muscles, tendons, and ligaments from overexertion or stress.
While growth hormone therapy is typically prescription-only and injections are very expensive, bodybuilders and athletes often look to underground sources for injection solutions. This is risky and can contribute to unexpected IGF-1 side effects and adverse reactions. However, there are other ways to achieve results that are safer. Learn how to naturally produce IGF-1.

Growth hormone, which initiates the production of IGF-1 in the liver, is a prescription only drug. It’s also very expensive.
Injecting insulin-like growth factor-1into the body when levels are already adequate based on age can also be a dangerous proposition. However, if you want to learn natural ways to increase IGF-1, first look to your diet. Which foods can help promote synthesis?
It can be found in a number of dairy products and animal meats and organs including liver. Talk to your doctor or a nutritionist or dietician or get online and do some research on your own.
Another way of raising IGF-1 levels is through use of nutritional supplements like deer antler velvet, which contains high levels of insulin-like growth factor-1, numerous amino acids, enzymes, vitamins, and minerals, all which promote health and wellness for the pituitary gland, responsible for releasing growth hormone that triggers IGF-1 production in the liver.
Another dietary supplement that may boost not only growth hormone levels from the pituitary gland but in turn, increase IGF-1 levels is through use of whey protein supplements added to drinks. One study published in the American Journal of Clinical Nutrition showed that protein supplements did create an increase in plasma IGF-1.
However, athletes considering IGF-1 supplements when learning how to increase IGF one naturally should know that it has been banned as a performance enhancer.
It’s been banned by the US Anti-Doping Agency, the World Anti-Doping Agency, and even the military, so it’s always important to check with athletic and sporting organizations to determine rules and regulations depending on sport – even when it comes to over-the-counter supplements.
It’s also important to remember that too much of anything can be detrimental to health. High levels in the blood, especially over the long term, can potentially increase the risk for developing cancer, overgrowth of the prostate gland, and hypoglycemia or low blood sugar. If you want to know how to increase IGF-1 naturally, speak to your doctor about changes in diet and exercise.
