What Are Some Functions Of The Liver – Before we dive into the interesting ways amino acids benefit liver health, let’s provide some context on how severe the consequences of not paying attention to liver health can be.
Based on statistics shared by the Centers for Disease Control and Prevention (CDC), there are over 4.9 million diagnosed cases of chronic liver disease in the United States. Of these, 40,545 cases die.
What Are Some Functions Of The Liver
According to the American Liver Foundation, “Anything that stops your liver from doing its job can be life-threatening.” There are many different factors that can interfere with liver function, such as…
Liver: Anatomy And Functions
Regardless of the underlying cause, the central risk is the same: that your liver becomes too damaged to function at the level you need to stay alive. And no matter what stops it, liver damage and disease continues along a familiar path.
One factor that accelerates the progression of liver disease is when a protein called Bcl-xl begins to malfunction, failing to control the release of another protein called cytochrome c, which occurs when liver cells die.
The release of cytochrome c causes a cascade reaction in the liver that eventually results in scarring of the liver—what medical professionals call “hepatic fibrosis”—and causes the development of chronic liver disease.
When it comes to discovering mechanisms for preventing liver disease and maintaining liver health, finding ways to ensure that the Bcl-xl protein functionally regulates cytochrome C is a top priority. And an exciting new study suggests that branched-chain amino acids (BCAAs) may do just that.

To understand how amino acids protect your liver, it is important to understand how the liver processes amino acids.
Did you know that your liver is the largest organ in your body? With this in mind, it is not surprising how many essential functions the liver performs. Your liver not only detoxifies your blood, but also processes nutrients and produces lipids, carbohydrates and amino acids.
Your liver produces a variety of proteins, such as albumin and fibrinogen, the two main plasma proteins that are responsible for many important functions. Albumin keeps blood volume balanced and transports essential amino acids throughout the body, while fibrinogen ensures proper blood clotting.
One of the main functions of the liver is to process amino acids that your body absorbs through protein digestion. Your liver uses enzymes called deaminases and transaminases to convert amino acids into forms more useful to your body.
Liver Regeneration: Biological And Pathological Mechanisms And Implications
Deaminase and transaminase enzymes can add nitrogen to synthesize non-essential amino acids, or remove nitrogen to leave intact carbon structures that can then be used to produce glucose or, less commonly, converted to fatty acids.
When these processes involve the release of nitrogen, a potentially toxic compound called ammonia is produced. Your liver then converts the ammonia into urea, allowing it to be safely removed from your body.
In the long term, excessive exposure to alcohol or other drugs, as well as nutritional deficiencies, can compromise your liver’s ability to perform these key jobs. Altered amino acid metabolism is one of the hallmarks of liver disease, and studies suggest that supplementing with amino acids—and especially BCAAs—can improve your liver health.
Some of the most exciting research into how amino acids benefit liver health was conducted by a team of scientists based in Kyoto, Japan. The team hypothesized that BCAA supplementation could slow, or possibly even stop, the progression of chronic liver disease.

After inducing liver disease in one group of mice, the researchers then divided the mice into two groups. One group received a diet supplemented with three BCAAs: valine, leucine and isoleucine. Another was the control group. During the 11-week study, weekly blood samples were taken from both groups of mice. At the end of the study, the researchers took liver samples.
The results of BCAA supplementation were quite dramatic. Blood levels of a liver enzyme called AST, which increases with the severity of liver damage, were on average 22% lower for the group given BCAA compared to the control group. And CTGF protein levels, a marker of liver scarring, were on average 75% higher in the control group.
Perhaps most importantly, levels of an enzyme called caspase 3 and a protein called albumin, which indicate the rate of cell death, were 100% and 80% higher, respectively, in the control group.
Based on these changes, the researchers concluded: “Supplementation with branched-chain amino acids delays the progression of chronic liver disease” and does so specifically by slowing the death of liver cells.

Alarmingly, the death rate from liver disease is on the rise in the United States, according to an analysis of data collected from across the country. Lead author Zober M. Unosi, MD, MPH, attributes this to the rise in non-alcoholic fatty liver disease (NAFLD).
“I believe it all has to do with the huge increase in obesity and type 2 diabetes in this country,” said Dr. UNOSI said in an interview before the annual meeting of the American Association for the Study of Liver Diseases. “These two risk factors drive NAFLD and its progressive form, nonalcoholic steatohepatitis (NASH). They account for at least part of the increased mortality associated with liver disease.”
Dr. Yunosi and colleagues analyzed findings from 838,809 deaths related to chronic liver disease. They found that overall mortality for chronic liver disease increased by 1.3% for men and 2.5% for women.
Non-alcoholic liver disease was the most common cause of death associated with chronic liver disease (34.7%), followed by alcoholic liver disease (28.8%) and chronic hepatitis C (21.1%). Between 2007 and 2016, the death rate from NAFLD increased from 7.6 to 9.0 per 100,000.

Dr. One of the most important points from the analysis, Unosi said, is that NASH — the most severe form of NAFLD — is fairly common in the United States. “These patients are under-recognized and under-diagnosed because they are asymptomatic.” But fatty liver disease can progress to full cirrhosis. Unosi believes it is important to identify treatments that can help fight the disease.
Human studies have confirmed that amino acid supplements can naturally and effectively treat non-alcoholic fatty liver disease and alcoholic liver disease, the two leading causes of death associated with liver disease.
Clinical studies have found that essential amino acids reduce liver fat as effectively as fenofibrate, a leading pharmacological treatment. And amino acids do not cause any negative reactions. Fenofibrate, on the other hand, can cause unpleasant side effects such as fever, hives and other skin rashes, muscle aches and pains, stomach pain and vomiting.
Scientists are still working to understand the metabolic changes that cause fat to accumulate in the liver, which then disrupts liver function and results in damage and disease. Many people have no symptoms of fatty liver in the early stages, but some possible warning signs include:

It is possible to minimize the damage associated with fatty liver disease and in some cases completely reverse it. Nutritional therapies that improve fatty acid metabolism in the liver, such as essential amino acids, can go a long way toward protecting or restoring liver health.

Liver function tests, also known as liver chemistries, help determine this. Your liver health by measuring the levels of protein, liver enzymes and bilirubin in your blood. They can also monitor the progress or treatment of an existing disease.
Depending on the test, higher or lower than normal levels of these enzymes or proteins may indicate a problem with your liver.
Some reasons to have a liver function test include checking for diseases such as hepatitis, monitoring the side effects of your medications, and checking the severity of your liver disease.
In this article, we take a look at when you might need a liver function test, the different types of tests used and how to interpret the results.
Elevated Liver Enzymes: Causes, Symptoms And Tests
Abnormal results in any of these liver tests usually require follow-up to determine the cause of the abnormal features. Even mildly elevated results can be associated with liver disease.
Alanine transaminase (ALT) is used by your body to metabolize protein. If the liver is damaged or not working properly, ALT can be released into the blood. This causes the ALT level to rise. A higher than normal result on this test can be a sign of liver damage.
When the liver is damaged, AST can be released into the bloodstream. High score in one
