What Is IGF-1 Hormone & Its Functions?

IGF-1 is produced by the liver naturally within our bodies, but as with many hormones and factors, it can be too high or too low and there are supplements and other means of enhancing your personal levels.

What is IGF-1?

What is IGF-1?

IGF-1 is insulin-like growth factor 1, also commonly referred to as somatomedin C. This substance is a hormone that somewhat mirrors insulin. This hormone is very important in growth for children and also activates anabolism in adults.

The IGF-1 is a protein that contains 70 various amino acids in a single-type chain. This protein is produced by your liver and is directly correlated to the human growth hormone. Your growth hormone stimulates IGF-1 for production. IGF-1 is highest during adolescence. Those who are more advanced in age have much lower levels of IGF-1.

IGF-1 Benefits

IGF-1 Benefits

The poll is still out on whether or not it is really good for you. But here’s what we’ve found. While the use is questionable for various reasons, it has proven to also provide substantial benefits in many areas as well.

As a young child, if you do not have appropriate levels of IGF-1, you may not grow as you are meant to. This could result in underdevelopment. If your IGF-1 levels are either too high or too low, there is an increased risk of infection, disease, and illness.

Here is a list of potential benefits:

  • Anti-Aging properties
  • Protection of cells
  • Increased antioxidant levels
  • Reduced inflammation
  • Immunity boost
  • Improved brain health
  • Decreased depression and anxiety
  • Bodybuilding, muscle increase, muscle mass
  • Balance blood sugar levels
  • Promotes growth
  • Improves gut health
  • Increased bone health
  • Rejuvenates skin

These benefits make it clear that IGF-1 certainly has something to offer, despite the negative feedback that has been provided. IGF-1 is still being tested for overall benefits versus the side effects, but these benefits have been found to be clear and consistent.

High IGF-1

High levels can become dangerous for your body, but again there are also advantages to heightened levels. It’s much better to find a balanced level and stay away from your levels being too high or too low.

High levels are better than low levels. Research has shown that the only benefit to low levels of IGF-1 is a reduced likelihood of cancer, but that benefit stands alone. Higher levels lead to an improved immune system as well as reduced inflammation.

Again, please know that the best level to focus towards would be a balanced levels, but if you are imbalanced, it is better to have high levels rather than low.

High IGF-1 Symptoms

High IGF-1 Symptoms

The reason it is so important to monitor your IGF-1 levels, especially when taking a supplement, is that there can be adverse effects if it is too high. Symptoms of high levels include:

  • Enlarged feet and hands
  • Oily skin that feels thickened
  • Excessive sweating
  • Skin tags
  • Enlarged facial features
  • Muscle weakness
  • Fatigue and weariness
  • Erectile dysfunction
  • Increased likelihood of cancer
  • Irregular menstrual cycles
  • Headaches
  • Deepened voice

It is becoming more and more clear why maintain appropriately balanced levels of this peptide is so important. The problem is, how can you track your levels without regular blood tests? If you do take a supplement to boost your IGF-1, we recommend that you are tested regularly to make sure you are at an appropriate level.

As with anything, if you are concerned with side effects and symptoms you are experiencing, be sure to reach out to your doctor.

IGF-1 Side Effects

The primary side effect occurs when IGF-1 levels are not balanced. You are more likely to experience death and disease at low levels while high levels can cause cancer and excessive testosterone-related effects.

If you experience any of these effects, you should work with a doctor and adjust your dosage as well.

IGF-1 Levels

IGF-1 Levels

IGF-1 levels are very important. You want to maintain a balanced level. When the levels are too low, there is an increased risk of disease and mortality, while if the levels are too high there is an increased risk of cancer and heavy testosterone-related side effects.

Healthy levels vary by age range because of how the body produces it. For instance, an individual in their 20s tends to have levels that naturally measure between 158 and 230 ml, while an individual in their 70s has levels between 85 and 95 ml.

This is an active reflection that IGF-1 levels significantly decrease as you age. An average level of 150 – 175 ml is recommended.

IGF-1 & Bodybuilding

IGF-1 & Bodybuilding

Bodybuilding is probably the primary reason that an individual takes IGF-1. When bodybuilding, it improves strength and muscle mass, promoting growth. Bodybuilders are consistently looking for supplements to improve their muscle mass quickly and effectively.

It is very common for bodybuilders to take various supplements. Many bodybuilders have to “plump” their muscles and strength in order to prepare for competitions. It is a steroid-free supplement that works well for bodybuilders and therefore has become a positive choice.

IGF-1 is considered a safe supplement for building muscle while also reducing recovery time. With use, muscles do not break down but fat is still burning and there are no steroids or stimulants in the supplement.

IGF-1 LR3 Dosage

IGF-1 LR3 Dosage

IGF-1 LR3 is a supplement. Dosage levels may vary based on needs and age. However, using it allows the user to take smaller dosages and not use the supplement as often. This is one of the most common supplements that bodybuilders use. It is often injected into the user.

Dosage levels range anywhere from 20 mcg to 120 mcg, depending on the user. Most commonly, the beginning dosage is 20 mcg to 40 mcg and it is often increased from there. The dosage can be split in half and injected directly into the biceps.

IGF-1 Foods

There are many foods that can positively affect IGF-1 levels. The majority of the time, levels need to rise rather than be lowered but there are foods that can be used for either situation.

Foods that help increase levels include:

  • Animal protein – meats and seafood
  • Dairy products
  • Soy

Foods that help decrease levels include:

  • Plant-based protein
  • Fiber-rich foods such as grains or beans
  • Fruits, nuts, and seeds
