What is Leucine?
Leucine Supplements: Benefits, Usage, Pros, Cons
Leucine is one of the three interlinked amino acids, often occurring with the acronym BCAAs (the other two are valine and isoleucine). HMB is an end metabolite of leucine when it gets inside the body. Leucine and the other two BCAAs are unique in their metabolic function because they are used mainly in muscle-protein synthesis.
Leucine is cheaper than HBM and has additional advantages. HBM’s normal dose is about 3 grams per day, but if you take leucine, then you should decrease it to about 1,5 grams. Leucine stimulates the protein synthesis in the muscles, contributes to the strengthening of the bones, skin, and muscle tissue, and stimulates the synthesis of the amino acid glutamine.
Most anabolic and anti-catabolic effects of leucine are attributed to its end product, namely HBM (betahydroxymethylbutyrate). It is important to know that leucine, together with any metabolite leading to the release of HBM, has a unique role in the body.

What Are the Benefits of Taking Leucine Supplements?
Leucine supplements are undoubtedly becoming popular, especially among athletes and bodybuilders. But what exactly are they used for? We will explore the role of leucine supplements in health, performance, and muscle growth. We will discuss the potential benefits of leucine supplementation and its possible side effects.
We will also look at the best ways to use leucine supplements for maximum benefit. So if you're wondering what leucine supplements are and why they are used, you're in the right place. Get ready to learn everything you need to know about leucine supplementation.
1. Increasing muscle mass
Leucine supplements are popular for increasing muscle mass, as leucine is the primary amino acid responsible for muscle protein synthesis. Leucine can be found naturally in certain foods, such as dairy products, eggs, red meat, nuts, and seeds. By taking leucine supplements, you can ensure your body has an adequate supply of this essential amino acid for muscle growth. Additionally, leucine supplements have been found to increase the rate of muscle protein synthesis, leading to improved muscle mass.
2. Enhancing athletic performance
Leucine supplements are often used to enhance athletic performance, as leucine is known to stimulate muscle protein synthesis by activating the mTOR pathway. Studies have shown that people who take leucine supplements can increase muscle size and strength and improve muscle recovery time. Leucine also increases energy levels, lowers fatigue, and improves endurance. By taking leucine supplements, athletes can increase their performance and improve their overall athletic performance.
3. Improving insulin sensitivity
Leucine supplements can be taken to improve insulin sensitivity. Insulin sensitivity refers to the body's ability to respond to the hormone insulin, which helps to control blood sugar levels. Insulin sensitivity can be improved with leucine supplements to promote healthy glucose metabolism and reduce the risk of type 2 diabetes. This can benefit people who are obese, have high blood pressure, or have a family history of diabetes. Leucine also helps to support healthy weight management by helping to reduce appetite and cravings for unhealthy foods.
4. Stimulating protein synthesis
Leucine supplements are frequently used to stimulate protein synthesis, which builds proteins from amino acids. This process is essential for the growth, repair, and maintenance of all cells in the body, including muscles, bones, and organs. Protein synthesis is also essential for metabolic processes, such as energy production and hormone balance. By taking leucine supplements, you can help to improve the efficiency of protein synthesis and aid in the recovery and growth of muscle tissue.
5. Increasing muscle strength
Regarding building muscle strength, leucine supplements can be a great option. Leucine is an essential amino acid found in foods such as protein, eggs, and fish, and it is one of the essential amino acids for muscle protein synthesis. Studies have shown that supplementing with leucine leads to increased lean muscle mass and greater strength gains than without supplementation. Leucine can also help prevent muscle breakdown and aid in recovery after exercise.
6. Accelerating recovery after exercise
Leucine supplements are most often used to accelerate recovery after exercise. This amino acid is essential for muscle growth and repair, and it's known to help reduce muscle soreness, improve repair times, and increase muscle mass. Studies have also shown that leucine can speed up the recovery process of athletes after intensive workouts and help them perform better in their subsequent workouts. Furthermore, leucine can also help to prevent muscle breakdown, which is especially important for people who engage in strenuous physical activities.
7. Boosting energy levels
Leucine supplements are also crucial for boosting energy levels. Leucine is one of the three branched-chain amino acids (BCAAs) essential for proper muscle development and energy production. Leucine is the most important of the three, as it helps to stimulate the production of glucose in the body, providing more energy and stamina. Studies have also shown that regular BCAAs consumption, including leucine, can improve overall energy levels and enhance exercise performance.
8. Preserving lean muscle mass during weight loss
Leucine supplements are important for preserving lean muscle mass during weight loss. When paired with a calorie deficit, leucine helps your body maintain muscle mass while losing excess fat. Leucine works by activating the mTOR pathway, which promotes muscle protein synthesis, enabling your body to maintain muscle strength and size. In addition, leucine can help preserve your muscle glycogen stores, which are essential for optimal exercise performance and muscle size maintenance.
What Are the Optimal Leucine Doses?
Leucine is cheaper than HBM and has additional advantages. HBM’s normal dose is about 3 grams per day, but if you take leucine, then you should decrease it to about 1,5 grams.
How to Take Leucine?
The 90-kilogram sportsman should take 2 to 4 grams of leucine before training in the form of supplements, and also after that, and again before going to bed or at midnight.
What Are the Possible Side Effects When Taking Leucine?
There is some evidence of the link between excess leucine in the diet and the development of the disease pellagra.
Which Products Are the Main Sources of Leucine and HMB?
These are the combined BCAAs, Amino acid supplements in combination with all other amino acids, or leucine as a separate product. Rare is the combination of HMB - Leucine. HMB is sold most often separately from other products or in specialized formulas for recovery.
What Are the Additional Physiological Effects of Leucine?
This amino acid stimulates the protein synthesis in the muscles, contributes to the strengthening of the bones, skin and muscle tissue, and stimulates the synthesis of the amino acid glutamine.
Why Should You Take Leucine?
Leucine is superior to other amino acids in the provoking of insulin response. It creates conditions for the sustained release of insulin, which in turn creates higher insulin anabolic effect on the body. Most anabolic and anti-catabolic effects of leucine are attributed to its end product, namely HBM (betahydroxymethylbutyrate). It is important to know that leucine, together with any metabolite leading to the release of HBM, has a unique role in the body.
How Is Leucine Absorbed by the Body?
The leucine molecules reach the blood after suction into the small intestine. It carries blood to the muscle cells. Therefore, it is better to take it with liquids before training.
Which Are the Foods That Contain Leucine in the Greatest Amount?
Leucine cannot be synthesized by the body, and therefore we must always get it from food sources. In larger concentrations, it could be found in meat and dairy products, especially whey protein, and to a lesser extent in wheat germ, brown rice, soybeans, almonds, cashews, peas, lentils, and corn.
In conclusion, leucine supplements can be effective in helping to support muscle growth and recovery. Still, it is essential to know the different forms of leucine and how much is needed for optimal results. With careful consideration, you can choose the best leucine supplement for your individual needs and ensure that you get the proper amount to maximize your workout results.
