What is Isoleucine?
What is isoleucine and what are its benefits for you?
Isoleucine (a-amino-b-methyl-n-valeric acid) is an essential amino acid that plays a crucial role in protein synthesis and muscle growth. It’s one of the three branched-chain amino acids (BCAAs), along with leucine and valine. BCAAs are important for maintaining muscle mass and preventing muscle breakdown.
One of the main benefits of isoleucine is its ability to enhance energy production.
It’s a key player in the citric acid cycle, also known as the Krebs cycle, which is responsible for generating ATP, the body’s main source of energy.
By promoting efficient energy production, isoleucine can help improve exercise performance and reduce fatigue.
Isoleucine also plays a role in regulating blood sugar levels. It can stimulate the release of insulin, a hormone that helps transport glucose into cells for energy.
This can be particularly beneficial for individuals with diabetes or those who struggle with blood sugar control.
Furthermore, isoleucine is involved in the synthesis of hemoglobin, the protein responsible for carrying oxygen in red blood cells. Adequate levels of isoleucine are essential for maintaining healthy red blood cell production and preventing anemia.
In addition, isoleucine has been shown to support immune function. It can enhance the production of immune cells, such as T-cells and natural killer cells, which play a crucial role in defending the body against infections and diseases.
Isoleucine Benefits
When it comes to your health, isoleucine offers several benefits that can support your overall well-being.
When you sit too much every day, you disturb your body’s natural functions, slow down your metabolism, and impair blood sugar regulation. Your circulation and heart health suffer, and your muscles and bones weaken. Mentally, you face a higher risk of anxiety and depression.
To counteract these effects, incorporate standing breaks, desk exercises, or walking meetings. Short, frequent movements can make a big impact.
Small changes like these can alleviate many issues associated with prolonged sitting. Learn how simple habits can greatly enhance your overall well-being.
Prolonged Sitting Disrupts Body Functions
Sitting for long periods can mess up your body’s natural functions. It can cause problems with your metabolism, blood sugar levels, and blood flow. When you sit too much, your body’s metabolism slows down. This means you burn fewer calories, which can lead to weight gain and obesity.
Sitting also makes it harder for your muscles to use blood sugar properly. This can increase insulin resistance and raise the risk of type 2 diabetes.
Your heart health can suffer too. Blood can pool in your legs, leading to poor artery function and a higher risk of heart disease.
It can also increase your blood pressure and cholesterol levels, which are bad for your heart. Poor blood flow can cause varicose veins and, in severe cases, deep vein thrombosis (DVT).
Sitting too long affects your muscles and bones as well. Bad posture can strain your back, neck, and shoulders, causing pain and possibly leading to problems with your spinal discs. Not moving enough can also weaken your bones, raising the risk of osteoporosis.
☝️ The human body was designed to move, jump, run, and do strength activities. It is not supposed to sit all day.
Over millions of years, our bodies have evolved to be very active and capable of many physical activities, like walking, running, climbing, and lifting. Our bones, muscles, heart, and brain are all made to work best when we move and exercise.
For most of human history, people had to be active to survive. They hunted animals, gathered food, farmed, and did other hard tasks every day. Sitting still for long times is something new for humans. This change happened because of machines, technology, and how work and free time have changed.
Now, many people spend too much time sitting, whether at school, work, or home, which can be bad for our health. Regular movement and exercise are key to staying healthy and avoiding these problems.
Excessive Sitting and Mental Health Risks
Sitting too much doesn’t just hurt your body; it can also affect your mind. Spending a lot of time sitting can increase the risk of anxiety and depression. The more you sit, the higher your chances of feeling anxious or depressed.
Studies from the Semel Institute for Neuroscience and Human Behavior at the University of California Los Angeles (UCLA) show that sitting a lot can affect the brain. Through MRI scans, researchers found that the more hours people spent sitting each day, the thinner the tissue in their medial temporal lobe (MTL), which includes the hippocampus. The hippocampus is largely responsible for storing and accessing memory. This means fewer new brain cells are made, which can hurt memory over time.
Interestingly, regular exercise alone doesn’t fix the problem. Even if you exercise a lot, sitting for long periods still poses a risk. Taking short, frequent breaks can help.
Research shows that people who stand up or move around every 30 minutes have about half the risk of anxiety and depression compared to those who don’t take breaks. [1]

How Much Do You Sit? – Interactive Quiz
1. Muscle Repair and Growth
Isoleucine is an essential amino acid that plays a crucial role in the synthesis of muscle proteins. [1]
It works by activating the mTOR pathway, which stimulates muscle protein synthesis and promotes muscle growth. [2]
Additionally, isoleucine helps to prevent muscle breakdown by reducing muscle protein degradation. Research has shown that supplementing with isoleucine can lead to increased muscle mass and strength.
It also aids in post-exercise recovery by reducing muscle soreness and promoting faster healing of damaged tissues.
To reap the benefits of isoleucine, you can consume foods rich in this amino acid, such as meat, eggs, dairy products, and legumes. Additionally, you may consider taking isoleucine supplements to support your muscle repair and growth goals.
2. Enhances Athletic Performance
To achieve enhanced athletic performance, incorporating isoleucine via BCAA supplements, into your diet can provide numerous health benefits.
A study explored factors causing fatigue during exercise. They found that changes in the brain’s 5-HT level, linked to fatigue, may be influenced by the transport of tryptophan into the brain.
This transport is affected by the availability of tryptophan and other amino acids like BCAAs (leucine, isoleucine, valine).
BCAA intake can increase their levels in the blood, reducing tryptophan uptake into the brain, potentially delaying fatigue.
When people took BCAAs during exercise, they felt less tired, performed better in mental tasks, and improved physical performance.
3. Improves Immune Function
By incorporating isoleucine into your diet, you can experience improved immune function and enjoy the health benefits it provides.
Studies suggest that isoleucine, is vital for various bodily functions like growth, immunity, and metabolism. It can boost the immune system and help fight off harmful substances. [3]
Recent research also shows that isoleucine can increase the production of defense peptides that enhance our immune response. [3]
In a study published in the journal “Frontiers in Immunology scientists”, looked at how adding l-isoleucine to the diet can help weaned piglets with rotavirus (RV) infection, a cause of severe diarrhea in young animals.
In cell experiments, l-isoleucine increased the production of defense peptides and immune-related signals. In live piglets, those given l-isoleucine had better growth and immunity. It reduced diarrhea, improved immune responses, and activated a defense signaling pathway. This suggests l-isoleucine might be helpful in treating RV infections in young animals.
4. Balances Blood Sugar
Maintaining balanced blood sugar levels is one of the health benefits of incorporating isoleucine into your diet.
For example, a study in rats looked at the impact of different branched-chain amino acids (BCAAs) on blood sugar levels.
When they gave the rats isoleucine, it significantly lowered their blood sugar levels 30 and 60 minutes after a glucose meal. Leucine and valine didn’t have the same effect. In muscle cells, isoleucine increased glucose consumption without needing insulin, while leucine and valine didn’t.
This suggests isoleucine may help lower blood sugar levels independently by enhancing glucose uptake in muscles.
In another study with rats, researchers examined how leucine and isoleucine affect blood sugar and muscle glucose use. They found that isoleucine lowered blood sugar levels when taken by mouth, while leucine increased the storage of glucose as glycogen in muscles.
Isoleucine boosted glucose uptake by muscles, but leucine didn’t. The difference was linked to changes in a molecule called AMPK alpha2, possibly due to isoleucine altering AMP levels.
This suggests isoleucine may help lower blood sugar by increasing muscle glucose use without affecting AMPK activity.
5. Keeps Your Brain Healthy
Isoleucine is an essential amino acid that plays a vital role in the synthesis of neurotransmitters – important nitrogen donors for synthesis of glutamate, the main excitatory neurotransmitter in the brain. [4]
It helps in the production of serotonin, dopamine, and norepinephrine, which are neurotransmitters responsible for regulating mood, memory, and concentration.
Studies have shown that isoleucine supplementation can improve memory and cognitive performance. It also promotes the growth and repair of brain cells, ensuring optimal brain health.
A study involving adults over 55 years old examined the impact of ingesting a powder containing seven essential amino acids, including leucine, phenylalanine, and lysine with isoleucine, histidine, valine, and tryptophan.
The research found that those who consumed this amino acid mixture for 12 weeks showed improved cognitive function, better attention, and cognitive flexibility. Their social interaction and psychological health also improved, potentially aiding in the prevention of cognitive decline.
6. Reduces Inflammation
Numerous studies have shown that isoleucine reduces inflammation and fights diseases causes by chronic inflammation.
For example, in a review article published in the journal “Current Protein & Peptide Science” suggests that Isoleucine plays a crucial role in various body functions like growth, immunity, and metabolism. It continues by saying that Isoleucine can boost the immune system, helping organs, cells, and defensive substances work better.
The article continues by stating that recent research suggests that isoleucine may even enhance host defense peptides, which regulate our innate and adaptive immunity.
Another research article in the FASEB journal explored the effects of valine and isoleucine on non-alcoholic steatohepatitis (NASH) in mice.
After a period of unhealthy eating, the mice were given these amino acids. Valine and isoleucine didn’t affect obesity or certain digestive factors but did reduce insulin levels. They also lowered liver damage, oxidative stress, and inflammation, improving NASH-related problems.
Research published in the Indian Journal of Physiology and Pharmacology explored the anti-inflammatory effects of orally administered amino acids like L-isoleucine, DL-isoleucine, L-leucine, and L-beta-phenylalanine.
These amino acids showed anti-inflammatory properties in various inflammation tests except for formaldehyde-induced inflammation.
L-isoleucine also had a lasting pain-relieving effect, and none of the amino acids caused stomach ulcers or acute toxicity.
7. Optimal Hormone Production
Isoleucine, plays a crucial role in hormone synthesis and regulation.
In a study, researchers investigated how L-isoleucine (Ile) and L-leucine (Leu) affect the release of certain hormones related to insulin and blood sugar regulation in inactive, healthy adults.
They compared the effects of Ile, Leu, a combination of both, and a placebo before an oral glucose tolerance test.
They found that Ile increased one of the hormones (GIP) more than Leu or the placebo, but this didn’t have a significant impact on insulin or glucose levels during the test.
8. Enhanced Nutrient Absorption
You can maximize the absorption of essential nutrients in your body by incorporating isoleucine into your diet.
When you consume isoleucine-rich foods, such as meat, fish, eggs, dairy products, and legumes, it stimulates the production of enzymes that aid in nutrient digestion and absorption.
These enzymes help break down complex molecules into simpler forms that can be easily absorbed by your body.
Additionally, isoleucine also promotes the release of digestive juices, such as bile and stomach acid, which further aid in nutrient breakdown and absorption.
A study on dairy goats looked at how isoleucine (an amino acid) affects the production of digestive enzymes in the pancreas.
When they added a lot of isoleucine, it made the pancreas release more alpha-amylase, an enzyme that helps digest food. It also increased the levels of trypsin and chymotrypsin, two other enzymes, but didn’t affect lipase. Isoleucine seemed to work by changing certain signaling pathways in the pancreas.
9. Helps in wound healing
Isoleucine, plays a significant role in wound healing as well.
Studies have shown that it can help speed up the healing process in various types of injuries, including injured muscles and wounds. [6]
In particular, research conducted on patients with diabetic foot ulcers (DFUs) found that higher levels of isoleucine in their serum were associated with better wound healing outcomes.
Along with other amino acids like arginine, leucine, and threonine, isoleucine seemed to have a positive impact on the healing of DFUs.
Potential Side Effects
While isoleucine is generally considered safe when consumed in normal amounts through food sources or supplements, some individuals may experience side effects.
Here are some potential side effects of isoleucine to keep in mind:
- Gastrointestinal Issues: Some individuals may experience digestive discomfort such as bloating, diarrhea, or nausea when consuming high doses of isoleucine. These symptoms are usually mild and temporary, but if they persist or worsen, it’s advisable to consult a healthcare professional.
- Allergic Reactions: Although rare, some people may have an allergic reaction to isoleucine. Symptoms of an allergic reaction may include itching, rash, hives, swelling, or difficulty breathing.
It is worth noting that these potential side effects aren’t common and most people tolerate isoleucine without any issues. .
