For those who are not familiar with the human growth hormone, also commonly referred to as HGH, it is a naturally-occurring hormone that is produced by the body's pituitary gland. And this peptide hormone is responsible for numerous bodily functions, including growth, cell reproduction, and cell regeneration. Of course, this only describes the big picture when it comes to human growth hormones in the human body. These multifunctional peptide hormones enable the body to maintain, build, and repair healthy tissue in the brain as well as other organs.

Studies show that HGH can help speed healing after an injury and repair muscle tissue damaged by exercise and other strenuous activities. And in the process of doing so, these hormones indirectly help individuals burn fat, build muscle, and boost their metabolism. It is worth noting that the many roles of HGH do not end there as it also contributes to healthy, better-looking skin.

According to one study published by the hormonal specialists of HGH Therapy Clinic of Miami, HGH can slow down aging and even reverse some age-related diseases, both of which can take a toll on the health and appearance of the skin.

What you should know about the Human Growth Hormone

Produced by the pituitary gland, the human growth hormone stimulates the production of IGF-1, also known as insulin-like growth factor 1, which plays a critical role in childhood growth. As such, the body naturally produces an abundance of HGH while we are young. However, as we age, the production starts to slow down. According to a study published by Today, which is a part of NBC News, HGH and IGF-1 levels peak during puberty and then start to decline in our 30s. While IGF-1 might not be quite as critical in adulthood, the body still requires a fair amount of human growth hormones to function optimally.

To put this into context, a normal and healthy growth hormone level in adult males is 0.4 to 10 nanograms per milliliter, according to data published by The same study data noted that, for adult females, 1 to 14 nanograms per milliliter is considered a normal and healthy range. That said, as these levels start to decline with age, many men and women turn to all-natural supplements and physician-prescribed hormone replacement therapies.

Can Low HGH Levels Affect Mood and Memory?

To better understand why so many men and women turn to supplements and physician-prescribed hormone replacement therapy treatments to boost and normalize their growth hormone levels, we should take a look at what happens when one becomes deficient in this peptide hormone. A study published by Colorado State University found that a reduction in growth hormone production triggers numerous changes in the GH (growth hormone) axis, including a decline in IGF-1. Although more common among children, a decline in IGF-1 can lead to stunted growth. Additionally, a significant drop in growth hormone production can also give way to the following:

  • Cardiovascular disease
  • Lack of stamina
  • Increased sensitivity to hot and cold temperatures
  • Weight gain
  • Weak muscles and bones

Along with these health issues, a significant drop in HGH can trigger psychological and emotional problems, such as depression and increased irritability. Some studies have also revealed that this same decline can adversely impact memory and overall mood. In fact, according to one study published in the Journal of Clinical Endocrinology and Metabolism, a peer-reviewed medical journal, low levels of human growth hormone has been linked to the development of Alzheimer's disease, especially among men.

While there is currently no cure for this neurodegenerative disease, there are many treatments that can help slow its progression. And human growth hormone replacement therapy (HRT) is proving to be yet another one, according to researchers and scientists involved in the study. It is also worth noting that HRT as a possible treatment for those struggling with Alzheimer's disease has drawn the attention of countless neurologists across America.

Human Growth Hormone-Based Therapy as a Treatment for Memory Problems

First and foremost, more than 5 million people in America are living with Alzheimer's, a degenerative brain disease that destroys memory and other critical mental functions in the brain. Adding to that, Alzheimer's is also the most common form of dementia among adults over the age of 65. Now that we are a little bit more up to speed when it comes to Alzheimer's disease in America, let's take a closer look at human growth hormone therapy as a form of treatment.

In a separate study published by, researchers found that individuals with mild cognitive impairment, which is an early sign of Alzheimer's, that received growth hormone injections experienced a 200 percent improvement mental processing skills as well as marked improvements in their ability to focus and concentrate. Further, many of these same individuals reported feeling less depressed and anxious.

Bottom Line

In summary, a decline in growth hormone production is yet another unfortunate part of getting older. For thousands of Americans, this also means a higher risk of developing neurodegenerative diseases, including Alzheimer's. Fortunately, HGH-based treatments are proving to be yet another way to slow the progression of these diseases while also providing help to improve one's cognitive abilities.
