BCAA 2:1:1 Capsules: Benefits, Dosage and Side Effects

What is BCAA 2:1:1 Supplement?

BCAA means branch chain amino acids as essential amino acids — leucine, isoleucine and valine. BCAA is a chemical configuration that separates them from the other essential amino acids for a more effective result.

The BCAAs establish 40 percent of your body’s protein and supply nearly 15 to 25 percent of the total protein intake. You can find the highest natural forms of BCAAs in red meat and many dairy products.

BCAA 2:1:1 is a ratio of essential amino acids: leucine, isoleucine and valine. Athletes and bodybuilders take this supplement for endurance and muscle building. The compound also helps to build strength, promote muscle endurance and assist your body in muscle recovery following a strenuous workout. It even helps maintain weight and blood sugar levels and supports your liver.

Understanding the benefits of amino acids, in general, will help you understand the overall advantages of taking BCAAs. Before taking any new supplement check first with your healthcare provider.

What are amino acids?

Amino acids produce protein in your body as compounds that support all metabolic processes influencing brain function, mood, energy and muscle performance (x).

What can amino acids do for the body? Your body requires amino acids to grow strong bones, muscular tissue, and healthy hair and skin. The body would not function without amino acids. These compounds help break down food while eliminating waste deposits connected with the body’s metabolism (x).

Organically, amino acids play a vital role in living a happy and healthy life.

There are 22 amino acids, and each one falls under three different categories to help keep the body functioning, including branched-chain amino acids. As mentioned before, BCAAs comprise three essential amino acids—leucine, isoleucine and valine. Many foods contain these amino acids, but you can also take BCAA capsules, such as BCAA 2:1:1. The 2:1:1 ratio refers to 500 mg per unit: 2 is for leucine at 1000 mg, isoleucine and valine are both 500 mg for 1:1.

Based on studies, these three essential amino acids work together somehow or another that may maintain muscle stability and recondition them after injury from exercise or overexertion. That way, athletes or weekend warriors notice an improvement in their athletic performance. With the added benefit that BCAAs support fat loss.

So, it’s safest to see your healthcare provider for permission, medical information and diagnoses before taking any new supplements.

Amino Acid Categories

Describing amino acids in categories helps you to understand how they facilitate the proper function of the body’s overall system. Also, some of these amino acids are not naturally in your body, so you must ensure your consumption meets your body’s needs.

  • Your body produces non-essential amino acids even when you don’t get enough from the food you eat.
  • Your body doesn’t produce essential amino acids, so you need to eat food that contains amino acids or take supplements.
  • When you and your body experience illness or stress or the body doesn’t generate enough quantities of amino acids, conditional amino acids kick in to meet individual needs. Arginine, cysteine, tyrosine, glutamine, glycine, proline, ornithine and siren are conditional amino acids.

Unquestionably, these compounds support your body and are vital to help maintain a healthy body. Altogether, 22 amino acids exist, with nine of those essential.

The essential amino acids are phenylalanine, histidine, methionine, tryptophan, isoleucine, valine, leucine and lysine. You can call a food source, plant or meat, that contains all nine amino acids a complete protein (x).

Any food source that lacks one or more essential amino acids is an incomplete protein. In a perfect situation, you can combine foods with different essential amino acids to make complete proteins. The combination needs to occur over a whole day. That way, a diet of one plant item will not give you the protein you need. Instead, look at what you eat throughout the day (x).

Foods With BCAAs

The essential amino acids that formulate branched-chain amino acids don’t generate in your body. You need to consume them food or supplements because they are essential — leucine, isoleucine and valine. These are the only three amino acids that have a branched side chain. That means they have a special chemical function on a module level with a side chain, or open chain, giving BCAAs their name (x).

Foods that contain BCAAs (x):

  • Meat, fish, and poultry
  • Dairy products like cheese and milk
  • Nuts and seeds, almonds, cashews and Brazil nuts
  • Tempeh and tofu, soy products
  • Legumes, like lentils, chickpeas, beans and peas
  • Whey, soy and milk proteins
  • Eggs
  • Whole wheat
  • Brown rice
  • Corn

BCAAs Metabolizes Directly into the Muscles

Though taking any form of compound naturally has its benefits, evidence shows the positive effects of BCAA as a supplement on muscle growth, especially the essential amino acid leucine. Studies support that leucine increases protein synthesis within the skeletal muscles as part of the branched-chain amino acids. It happens after young people finish resistance exercise and when older adults experience muscle loss (sarcopenia).

Studies also observe positive effects against fatigue caused by the production of endogenous glucose and maintain the body’s glucose balance while adapting to stress. Thus, the breakdown of BCAA in the muscles than in the liver helps energy production and muscle synthesis during exercise. Interestingly, studies noticed administering high doses of BCAA caused no toxicity (x).

Role of Each BCAAs


Leucine is the most influential essential amino acid of the other BCAAs because it breaks down and assimilates into your body faster. That way, your body uses leucine faster than valine and isoleucine. It develops and repairs muscle fibers by generating B-hydroxy-B-methyl butyrate (HMB). Thus, it creates a positive reaction in your muscles, protecting them and helping them grow (x).


Isoleucine causes hemoglobin synthesis, where the hemoglobin, as a protein molecule in red blood cells, moves oxygen generated from the lungs to the tissues of the body. The amino acid is also responsible for monitoring blood sugar and energy, regulating glucose consumed through food. Then becomes cells where glucose breaks down into energy. That way, isoleucine may help to enhance your athletic performance while functioning as a hypoglycemic agent. Thus, the BCAA lowers the body’s glucose levels within the blood (x).


Studies show that valine can give athletes and bodybuilders an additional boost, helping their performance. The extra boost also helps prevent muscle breakdown by supplying the muscles with additional glucose. As a result, the body can generate more energy during intense exercise. Valine also plays a part in the BCAAs’ ability to fight fatigue (x).

Biologically, the BCAAs function as a group, thanks to them being the bulk of the total amino acid supply of the body. BCAAs deliver 35 to 40 percent of all essential amino acids in your body and 14 to 18 percent in the muscles.

The body uses BCAAs to break down protein in the muscle rather than in the liver, helping to preserve the body’s store of glycogen, a glucose that fuels your muscles for energy production — exercise. That way, your body uses BCAAs to help build muscle protein and produce energy while helping to avoid exercise fatigue (x).

What are BCAA Supplements Used for?

Research shows that besides supplementing with BCAAs to build muscle mass, other reports indicate that the amino acids may have other health benefits. BCAAs have protein-synthesizing results, leading directly to increased muscle mass and energy while reducing muscle fatigue (x).

Sports nutrition is one of the primary uses of BCAA supplementation, which is broad. Many experts, dedicated athletes and fitness enthusiasts praise the benefits of taking branched-chain amino acid capsules. Knowing how these compounds work doesn’t take a rocket scientist to understand. (xx).

Building Muscle Mass with Protein Synthesis

Studies show that BCAAs help build muscle mass, thanks to the natural ability of the compound to synthesize protein. Research also shows that taking BCAA capsules with other whole proteins like whey, soy and milk enhances the anabolic effect, building muscle, maintaining bone density and accelerating recovery from injury (x).

Leucine is exceptionally at activating muscle protein synthesis, aligning with the other amino acids. Then, together, they work, producing new muscle. Scientifically, BCAAs help enhance mRNA translation, which is the mechanics of protein synthesis (x).

The body builds muscle when it’s in a state of positive protein balance. Your body goes through muscle protein turnover continuously. To put it differently, continuous protein turnover occurs during muscle protein synthesis (MPS) and muscle protein breakdown (MPB). While the total muscle protein synthesis is higher than muscle protein breakdown, your body builds new muscle.

Conversely, if MPB surpasses MPS, the body will experience muscle deterioration. Research recommends that supplemental BCAAs may help speed up muscle protein synthesis. An enhanced MPS speed results in a positive protein balance and raises the probability of more muscle mass (x).

Preserves Body’s Energy with Glucose Metabolism

Taking BCAAs capsules helps maintain and preserve your body’s glycogen storage. Glycogen is a form of stored glucose to give your body a quick boost of energy. Or your body needs glucose because the food hasn’t supplied it, then the body breaks down glycogen to release glucose into your bloodstream, fueling cells (x).

Storage of glycogen fuels muscles so they can produce. Copious of stored glycogen helps ensure the body uses muscle protein for energy. That way, athletes can sustain sufficient stamina to endure strenuous exercise, such as running a marathon or competing in a swim meet.

If the glycogen reserves in your body run low, the body can take advantage of BCAAs for fuel. These three essential amino acids play an important role in helping athletes, such as elite wrestlers, which they praise. BCAAs supplements may help you accomplish your training goals (x).

Also backed by eight studies surmises using these essential amino acids encourages both active and passive recovery. These components reportedly lessen muscle discomfort and sustain muscle movement after an extensive exercise session.

An interesting fact about working out is that you participate in vigorous exercise. Your body produces tryptophan, an essential amino acid. Tryptophan encourages the release of serotonin in your endocrine system. Studies speculate that serotonin may cause the body to feel fatigued, sluggish and tired after a strenuous workout (x).

BCAAs Non-Workout Benefits

Helps Maintain Intestinal Health

Studies performed on humans and animals show that BCAAs are valid regulators in helping to maintain intestinal health besides boosting your workouts.

BCAAs help provides systemic concentrations of gut bacteria, which positively influence and control the development of insulin resistance and type 2 diabetes (x).

Boost the Immune System

Studies also report that BCAAs can help boost your immune system by increasing fuel sources to the immune cells to help curtail the adverse effects of liver disease. BCAAs even support pro-inflammatory and improve certain digestive enzymes (x).

Inhibit Breast Cancer

Research shows that BCAAs knock down cancer-causing components, which inhibit breast cancer cell growth (x).
