The Best Amino Acids For Muscle Growth (April 2019) – I Bet You Did Not Know This!

the best amino acids for muscle growth 2019

Amino acids are basic building blocks of proteins. The value of proteins found in foods of plant and animal origin is estimated based on the amino acid composition.

Amino acids synthesized in the body are called non-essential, while amino acids that our organism is not able to synthesize call essential amino acids and therefore they need to be fed through the diet.

In this article, you will discover the best amino acids for muscle growth and why you should consume it if you want to burn calories and build perfect muscle mass. Amino acids are not only for weight loss and muscles but they can greatly boost your immunity, energy, metabolism and more.

The essential amino acids include amino acid tryptophan, amino acid phenylalanine, amino acid lysine, amino acid threonine, amino acid valine (BCAA), amino acid methionine, amino acid leucine (BCAA), amino acid isoleucine (BCAA) amino acid arginine and amino acid histidine.

The first eight amino acids are necessary to maintain nitrogen balance, while the amino acid histidine is essential only for children in the growth stage, and the amino acid of arginine adults can be synthesized in the tissues or made up by microorganisms of the intestine and is optional.

Non-essential amino acids are amino acid glycine, alanine, serine, then, amino acid norleucine, asparagine, then, very important amino acid for the recovery of muscle glutamine, glutamic acid, proline, hydroxyproline, as well as amino acids citrulline, tyrosine, and amino acid cystine.

The characteristic of the amino acid preparations is that they pass very quickly after their entry into the bloodstream, but the total amount of material is very small. For this reason, the use of amino acids should primarily shorten the time of absence of protein support from the bloodstream after a night’s sleep or strenuous training.

Taking amino acids supplements shows positive effects on:

  • strengthening immunity
  • recovery and regeneration after injuries, operations, etc.
  • protection of muscle from degradation
  • stimulation of the secretion of natural growth hormone
  • more intense burning of fat.

1. Scitec Nutrition BCAA Xpress

  • strong anabolic effect (muscle building)
  • anti-catabolic effect (prevention of muscle breakdown)
  • faster recovery and higher energy levels
  • with the taste of apples, pears and red oranges

The branched-chain amino acids (L-leucine, L-isoleucine, L-valine) play a very important role as they prevent catabolic processes in the muscles during strenuous and long-lasting training.

The body uses BCAA as an indirect source of energy for muscles transforming it into glucose, through a process known as glyconeogenesis, which is performed in the liver. BCAA, especially leucine, stimulates the secretion of insulin, somatomedin-C (IGF-1) and growth hormone (GH).

Thus, their anticatabolic effect is supplemented by direct natural anabolic action of said hormones and growth factors. An absolute imperative is for athletes to take BCAA supplements before and after completing intense weight training, as valine, leucine and isoleucine are consumed very quickly.

In terms of building and maintaining muscle mass, there are no more important amino acids than BCAA.

BCAAs have been used as supplements for years, and the largest consumers are bodybuilders and those who want to lose excess pounds.

Recommended use: Mix 7g (one dose) of the supplement with at least 2.5 dl of your favorite drink, use before, during or after training or at any other time, e.g. Before going to bed. To ensure a better dissolution, let it stand a little bit. Prepare immediately before consumption.

Ingredients: L-leucine, L-isoleucine, L-valine, acidity regulator: anhydrous citric acid, apple aroma, sweeteners: sucralose, acesulfame-K, dextrose, malt extract (from barley), color: riboflavin

Information on allergens: It may contain traces of milk, egg, gluten, soybean and peanut proteins. It is not recommended for people sensitive to any of the ingredients, pregnant women and nursing mothers.

2. Amino Power Liquid Mandarin By Weider

  • complex of amino acids in liquid form for rapid absorption
  • with the addition of BCAA (branched chain amino acid) and arginine
  • faster recovery and protection of muscles from catabolism (decomposition)

Nitron is recommended for athletes who need high-fasting amino acids. One portion of nitron provides the body with a high amount of rapidly absorbed amino acids, which are a mixture of whey hydrolyzate and collagen hydrolyzate. Nitron is additionally enriched with BCAA and arginine, making its composition even richer in terms of the biological value of the preparation.

Its ingredients, which provide energy, make training extremely effective as well as muscle regeneration after training.

Free forms of amino acids are crucial for the anticatabolic effect and the recovery of musculature under stress.

BioTech Nitron not only has good taste, but it also provides fantastic results! Its use is particularly recommended during hard training or competition season.

It is an excellent solution for all athletes, who are extremely important to keep their muscles constantly in the anabolic state, with an appropriate supplemental system with carbohydrates.

Recommended Use: Take one dose ( 2 tablespoons per day) after training. For days without training, take one dose in the morning. It is not recommended for people under the age of 18 years.

3. Scitec Nutrition BCAA X 120 Capsules

  • BCAA amino acids for the construction and preservation of muscle mass
  • Faster recovery
  • higher power level
  • weight loss

The basis of Scitec’s BCAA X preparation consists of BCAA (branched chain amino acid) which are branched amino acids, which include L-valine, L-leucine and L-isoleucine. These amino acids are among the essential amino acids, which means that they need to be fed through food or supplements because the human organism is not able to produce it themselves.

In the case of exposure to an organism with increased physical effort or inadequate intake of food, there is a breakdown of muscle mass, i.e. a catabolism process, and in order not to occur, there is a solution in the form of BCAA X.

BCAA X has a strong anabolic effect, increases protein synthesis and affects the natural increase in hormone production.

BCAA X, in addition to having an anabolic effect, is also an anti-catabolic because the present amino acids L-lysine, L-leucine and L-valine prevent muscle mass decomposition and provide the necessary energy to the cells.

What is particularly considered when formulating this supplement is the ratio of the mentioned amino acids, which according to my findings was found to be the most optimal ratio of the mentioned amino acids 2:1:1 – leucine: isoleucine: valine, in order to achieve the desired result.

Recommended use: Take 1-3 doses daily, both before and after training and at the time of catabolism (eg before bedtime). It is not recommended for people under the age of 18, pregnant women and nursing mothers, nor for people allergic on any of the ingredients.

4. Mega Amino 3200 by BioTech USA

  • A complex of essential and non-essential amino acids
  • They help build muscle and prevent their degradation which will result in weight loss
  • They enable faster recovery after strenuous training

Mega Amino 3200 are amino acids of 100% pharmaceutical purity and are derived from whey protein isolates, calcium caseinate isolates, hydrolyzed soy protein, and pea protein isolate.

After taking and immediately after the absorption of the amino acids reaches the bloodstream, they help in the continuous maintenance of the positive balance of nitrogens, prevent the catabolism process, accelerate recovery and muscle growth.

Studies have shown that the lack of amino acids during an increase in physical load leads to the decomposition of muscle tissue in order to cover the needs of an organism for energy.

The next important role of amino acids is to help degrade fat in cells, accelerate the pituitary gland, and thus stimulate the natural secretion of growth hormone, which leads to the build-up of muscle tissue without fat.

Mega Amino 3200 is extremely rapidly absorbed in the body, easily reaching the bloodstream, thereby accelerating recovery and reducing the risk of catabolism – the breakdown of muscle tissue.

Recommended use: Consume one serving (4 pills) 15 minutes before the activity and one immediately after the activity. In days of pause, consume one serving in the morning and one evening on an empty stomach. It is not recommended for people under the age of 18.

5. Amino 5600 by Scitec Nutrition

Amino 5600 represents the entire spectrum of amino acids with all essential and critical amino acids for maximum support for muscle building and their protection against degradation during prolonged training or a diet.

The Amino 5600 is produced from high-quality whey protein, of high biological value to ensure optimum resultant effect.

It is known that amino acids are building blocks of proteins. In order to make progress in muscle mass or just protect tissue from degradation, a constant flow of amino acids into the bloodstream is required.

This is achieved naturally firstly by the intake of protein foods, but also by supplementation.

Supplements, i.e. the amino acids in the tablets are rapidly absorbed, quickly reach the bloodstream and thus feed your muscles.

If you have hard and long training, you risk losing muscle mass and, on the other hand, you shake body balance and your body needs a quick recovery, so amino acid supplements should be at the top of your list.

Whey is also the richest source of branched-chain BCAA amino acids, well-known for its anti-catabolic effect and shortening of the recovery period, as well as the launch of the anabolic process.

Recommended Use: Take one dose (4 tablets) before or after training or before going to bed.

7. L-Glutamine Powder Fuel by Best Naturals

  • Makes easier muscle growth
  • accelerates metabolism
  • provides anabolism
  • accelerates protein synthesis
  • accelerates recovery after strenuous training

L-glutamine powder fuel provides 4.5 g of pure L glutamine per portion. L – glutamine is the most commonly used amino acid in the human skeleton and is known to provide excellent support for muscle building but also to protect the muscles from the degradation of the so-called catabolism.

Glutamine fuel is a powdered product that dissolves in your favorite beverage. You can even add it to the 310 protein shake.

Since it is consumed in liquid form it is easier to disintegrate into the body and therefore it is easier to absorb.

The relationship between glutamine and musculature is particularly important – the amount of glutamine is directly related to muscle building.

The main amount of glutamine is formed in the muscles, so the muscles are supplied by the immune system. Since it makes up more than half of all amino acids in skeletal muscles, its stocks must be filled regularly, otherwise, muscle breakdown may occur.

Glutamine is a necessary supplement for all serious athletes, but also for recreationists who want to make progress in a faster and more efficient way and burn more fat.

Dosage and method of use: a coffee spoonful of powder (5 grams) per day, dissolve in water or juice, and you can also add to a protein shake.

8. Icon Muscle BCAA 7000

  • It encourages muscle building
  • Increases muscle strength
  • Delays fatigue and speeds up recovery
  • Prevent muscle breakdown
  • With an exotic taste of mixed berries

Why BCAA 7000?

Because it is a dietary supplement designed to stimulate muscle building, preventing their degradation, providing additional energy potential and delaying and reducing fatigue and exhaustion.

All these effects of a single preparation are enabled by carefully selecting and combining ingredients: BCAA (branched chain amino acid) in an ideal regenerative ratio of 3: 1: 1 (L-leucine, L-isoleucine, L-valine), L-glutamine and vitamin B6.

In terms of building and maintaining muscle mass, there are no more important amino acids than BCAA. The branched-chain amino acids (BCAA) are found in the proteins of all living beings and account for a third of the daily requirements for amino acids in humans.

They play a very important role in the regulation of energy and the metabolism of proteins.

BCAA has been proven to accelerate muscle synthesis and prevent their catabolism, which is invaluable when the body is in a state of stress, which intense training certainly is. Thanks to this effect of the branched chain amino acid supplementation, BCAA supplementation is a sure way to increase muscle growth.

In addition to BCAA, L-glutamine, a semi-essential or conditionally essential amino acid is also present in the product.

Namely, under normal conditions, the body manages to synthesize sufficient amounts of glutamine, but in extreme, metabolic stress situations for an organism such as, for example, trauma or intense physical effort L-glutamine becomes essential acid. In such situations, we must ensure that his adequate additional input is provided.

What does L-glutamine do for us? It is one of the most important amino acids when talking about the impact of recovery speed after training. It participates in the synthesis of proteins, the production of energy as well as the necessary production of D-glucose and glycogen has an antioxidant effect and has a beneficial effect on our immunity.`

Excellence BCAA 7000 contributes to the addition of vitamin B6 which contributes to the synthesis of proteins, maintenance of normal energy metabolism, influences the control of metabolism of proteins and glycogen, positively affects immunity, regulates hormonal activity, reduces fatigue and exhaustion and helps in weight loss.

Usage: Mix 2 scoops (approximately 8 g) of powder with 200 ml of cold water and consume before, during and after the training.

Tip: To increase endurance: take 1-4 scoops 30 minutes before training; For recovery: take 1-3 scopes after training, at least 4 hours after the first dose taken before training. Do not exceed 6 doses a day!

9. 100% Pure L-Glutamine by NutraBio

  • faster recovery and regeneration of the body
  • natural stimulation of anabolism (muscle building)
  • prevention of catabolism (muscle breakdown)
  • stronger immunity

Glutamine is one of the most important amino acids in both bodybuilding and endurance sports because it significantly affects recovery after strenuous training. Glutamine accelerates overall body recovery by playing a particularly important role in restoring and building muscle mass.

In case of illness and stress (training is also stress), the musculature requires more glutamine than the organism can provide and generate from its own reserves. In this quest begins the decomposition of muscle tissue resulting in side effects.

This process can be avoided by supplementing glutamine products.

Glutamine has a strong effect on the metabolism of the protein (increase in their incorporation), on the effective synthesis of glycogen in the liver (increase in energy supplies), and directly affects the reduction of muscle inflammation.

Stimulates the secretion of the natural growth hormone and increases the volume of muscle cells in insulin coagulation.

In addition, it provides fuel for cerebral cells by focusing on mental abilities and concentration. All we need to mention is that large quantities of glutamine are engaged in the production of the most powerful antioxidant in our body, glutathione, which makes its connection with the general state of the organism quite obvious.

Ingredients: L-glutamine 100%.

How to use it: mix 1 dose (6g – 1/2 scoop) with 250 ml of water or some other beverage and mix well. Take once daily, before, during or after training. Prepare fresh, immediately before use!

10. Pure Micronized L-Glutamine by LabTech

  • Accelerates recovery after intensive training
  • Prevent muscle breakdown
  • It encourages muscle building
  • Micronized glutamine – faster and more complete absorption
  • It strengthens immunity

Glutamine is an amino acid that is naturally found in muscle tissue. Glutamine has a major share in the volume of muscle cells and the production of natural growth hormone. It is very important after intensive training when the body needs more glutamine than it can produce. It is then necessary to add glutamine in order not to break down the muscle tissue due to its lack.

As with other amino acids and L-Glutamine plays a significant role in protein synthesis and in muscle regeneration. L-Glutamine is not only important for muscle tissue, it also strengthens the immune and digestive system.

Although L-Glutamine is classified as an unsaturated amino acid, it is actually conditionally essential because it is consumed in physical effort and psychophysical stress and needs to be added to the body.

During the training, the level of amino acids decreases, which in most cases cannot be compensated. Low L-Glutamine levels lead to the decomposition of muscle tissue, which reduces the volume and capacity of the musculature.

The organism is not capable of perfect regeneration or for building muscle cells. L-Glutamine increases strength, reduces recovery time between training, reduces muscle inflammation, helps increase muscle mass, initiates and maintains anabolic processes and prevents the breakdown of muscle tissue.

Pure micronized glutamine is processed with micronization technology (the method of the finest particle fragmentation) for better and faster availability to our organism.

Recommended Use: Enter the contents of 1 teaspoon (5 g)

Use it after training with shake rich in carbohydrates and proteins immediately before bedtime, preferably with a protein drink and/or with a protein drink.

11. BCAA+ (2:1:1) by Power Run

  • easier maintenance of muscle mass
  • prevent catabolism
  • accelerate recovery
  • without taste
  • easily soluble

BCAA 2:1:1, branched chain amino acids play an important role in the construction of muscle tissue, that is, they represent one-third of muscle tissue.

At the same time, they keep glycogen reserves in the muscles of excessive disruption during physical effort.

The body uses BCAA as an indirect source of energy for muscles transforming it into glucose, through a process known as glyconeogenesis, which is performed in the liver.

BCAA 2:1:1 is a powdered product that can easily melt in your favorite beverage.

There is no taste, so you can consume it with your favorite beverage.

Recommended Use: Mix one dose (5g = 1 dose) with a minimum of 250 ml of water or some other drink and use 1-2 times a day, before, during or after training.

Or anytime during the day, for example before bedtime.

The Role of Amino Acids

The most important chemical reaction of amino acids is the formation of a peptide bond that allows the association of two amino acids and the formation of the amino acid chain (peptides and proteins).

Essential and non-essential

A total of 20 amino acids are added to the human body. 9 of them can be built in the body itself, while the remaining 11 need to be fed through the diet.

Amino acids that the human organism is unable to produce, and necessary for its functioning are called essential amino acids. I will describe in detail the essential amino acids, headed by three amino acids, more commonly known as BCAA and branched chain amino acids (Leucine, Isoleucine and Valin)

Valin amino acid is an essential amino acid (the human body cannot be synthesized). The source of the valine in the diet is fish, cheese and some seeds.

Leucine is the essential amino acid (the human body cannot be synthesized). Leucine is found in many foods such as dairy products, veal, pork, chicken and leafy vegetables.

Isoleucine amino acid is also an essential amino acid. Isoleucine is synthesized in plants and micro-organisms. A rich source of isoleucine in the diet are eggs, chicken, pork, soy, cheese, milk and others.

Below I describe the remaining 8 essential amino acids that we have to eat in the body through diet, that is, supplements.

Methionine amino acid is a non-polar essential amino acid and the only one, with amino acid cysteine, contains sulfur. Methionine amino acid is an intermediate in the biosynthesis of cysteine, carnitine, taurine, lecithin and other phospholipids. In human metabolism, he serves in biochemical reactions.

Phenylalanine amino acids, animals cannot be synthesized, but they are introduced into the body by the diet. Phenylketonuria is a hereditary metabolic disorder of the impossibility of metabolizing phenylalanine.

Tryptophan amino acid – for many organisms and humans, tryptophan is the essential amino acid. Which means it can not be synthesized in the body, but it has to be fed with food. The main role of amino acids, including tryptophan, is the construction of proteins. In addition, tryptophan has an additional role, builds: Serotonin, Melatonin, Niacin (Vitamin B3)

Threonine amino acids are synthesized in plants and microorganisms from aspartic acid.

Lysine amino acid is an essential amino acid. Amino acid lysine is a necessary building element of all proteins of the human body. The source of lysine in the diet is found in cereals, legumes and fish.

Glycine amino acids are the simplest amino acid among protein amino acids, especially important when building certain structures (eg collagen).

Histidine amino acid is found in fruit such as bananas, meat, and dairy products. It can also be found in a variety of vegetables but in smaller quantities. Histidine creates histamine.

Arginine amino acid (a human organism can be synthesized depending on the degree of development and health status of an individual). Arginine amino acid is found in many foods: chocolate, meat (pork, veal, seafood, feathered animals), dairy products and seeds.

Amino acid arginine plays an important role in cell division, healing of the wounds, excretion of ammonia from the body, a release of the hormone and has an immunological role.

It is also important to describe the following non-essential amino acids:

Tyrosine amino acid is a neurotransmitter and amino acid that stimulates brain activity. It has the most in milk products, bananas, beans, avocados, sesame and almonds. It promotes the proper functioning of the thyroid gland, pituitary glands, and encourages the release of growth hormone and noradrenaline.

It prevents depression, fatigue and irritability … L-tyrosine supplements should preferably be taken with a meal that is abundant with carbohydrates or before going to bed.

Alanine amino acids participate in metabolic pathways of glycolysis, glyconeogenesis and citric acid cycle.

  • Tolu

    I appreciate this well-detailed post on the best amino acids for muscle growth. As a science student, I know that amino acids are the building blocks of protein, however, I just learned here that amino acids work well for weight loss and muscles, besides their roles in improving immunity and metabolism. 

    The pressure of the age we live in, make most of us careless with our lifestyle especially our eating habits; that said, taking amino acid supplements can compensate for a lack of amino acid in one’s diet. I would need to get one for myself. 

    • Daniel

      That’s right Tolu, we really live in a stressful time where we don’t pay much attention to our health. This kinds of supplements are great not only for muscle growth but also for overall health. We should consume quality proteins every single day and sometimes it is not possible through food.

  • Sherry

    Great article! I am somewhat educated on amino acids and know of their importance in maintaining muscle mass and overall health!
