With the help of essential amino acids like leucine, isoleucine, valine, lysine, and more, you can boost your muscle growth, prevent muscle loss, and recover faster after workouts. But that’s not all – these supplements can also give you a natural energy boost, improve your sleep quality, and even promote healthier skin and teeth.
If you’re curious about the benefits of essential amino acid supplements and want to learn more, you’re in luck. This ultimate guide has got you covered. We’ll dive into what essential amino acids are, how they work, and the best supplements on the market.
And while all amino acids are important, we’ll focus specifically on the group of nine known as Essential Amino Acids (EAAs). These are the ones that fitness enthusiasts should pay extra attention to, as they play a critical role in the body’s processes during and after exercise.
So, are you ready to become an amino acid expert? Let’s dive in and discover all you need to know about Essential Amino Acid Supplements.
What is Amino Acid?
Amino acids often referred to as building blocks of protein are organic compounds counting nitrogen, carbon, hydrogen, and oxygen, crucial for many different processes in the body.
There are 2 different types of amino’s namely:
- Essential Amino Acid
- Non-essential Acid
As the name indicates, essential amino acids are necessarily required by the body and must be acquired via diet on a regular basis, while non-essential amino acids are synthesized by the body on a regular basis and are not necessarily required to be taken through diet. However, this definitely does not mean that non-essential amino acids can be taken for granted.
The most generic source of essential amino acids is animal protein like meat, egg, and poultry. For this reason, a vegetarian diet often lacks essential amino acids.
9 Classified Group of Essential Amino Acids
The human body requires both; Essential and Non-essential amino acids to function properly. However, only nine are classified as essential amino acids as they perform a number of crucial and varied jobs in the human body:
Phenylalanine is a forerunner to tyrosine, dopamine, epinephrine and norepinephrine neurotransmitters. It not only plays an extensive business in the formation and action of proteins and enzymes but also aids in the formation of other amino acids.
Valine is one of the three branched amino acids, which means that it has a chain that branches off to one side of its molecular formation. Valine helps to boost muscle development and regeneration and engages in the production of energy.
Threonine is a major component of structural proteins such as collagen and elastin, which are significant skin and connective tissue elements. It also plays an important part in immune function and fat metabolism.
Like valine, leucine is one of the branched-chain amino acids that is remarkable for protein synthesis and rebuilding of muscles. Also, it helps to balance blood glucose levels, encourages bruise curing and assembles growth hormones.
Tryptophan is a precursor for serotonin responsible to regulate sleep, mood, and appetite. Tryptophan also possesses pain-concealing qualities and can increase pain resistance ability during intense workouts or competitions.
Methionine is an important amino acid crucial for boosting the body’s detoxification and metabolism. Also, it has a key role to play in the growth of tissues and the absorption of vital minerals like zinc and selenium.
It is one of the 3 branched amino acids required for immune function, energy production, and muscle metabolism.
Lysine is another very important amino acid required for protein synthesis, hormone and enzyme production, and calcium absorption.
Histidine is required to produce histamine which is critical to the normal functioning of the immune system, sexual function, sleep-wake cycle, and digestion.
The above information clearly indicates that for many decisive processes essential amino acid is crucial. Not only are they perceived for their role in muscle advancement and rectification, but the body counts on them for so much more.
Benefits of Essential Amino Acids in the Bodybuilding / Fitness World
Now let’s talk about the benefits of Essential Amino Acids in the bodybuilding/ fitness world. It’s no secret that many athletes and fitness enthusiasts use supplements to enhance their performance and achieve their fitness goals. One supplement that has gained popularity in recent years is Essential Amino Acids or EAAs.
1. Ability to Improve Muscle Protein Synthesis
One of the key benefits of EAAs in the bodybuilding/fitness world is their ability to improve muscle protein synthesis (MPS). MPS is the process by which the body repairs and rebuilds muscle tissue after exercise-induced damage.
Research has shown that supplementing with EAAs can stimulate MPS more effectively than consuming just one or a few amino acids.
In fact, a study published in the American Journal of Clinical Nutrition found that consuming a supplement containing EAAs improved muscle protein synthesis in healthy young men. The study concluded that “essential amino acids are necessary for the stimulation of muscle protein synthesis in healthy young adults”. 1
2. Ability to Improve Muscle Recovery Post Workout
In addition to improving MPS, EAAs have also been shown to improve muscle recovery after exercise. A study published in the Journal of the International Society of Sports Nutrition found that supplementing with EAAs reduced muscle soreness and improved muscle recovery in trained men after a bout of resistance exercise. 2
3. Ability to Improve Endurance Performance
EAAs have also been shown to improve endurance performance. A study published in the Journal of the International Society of Sports Nutrition found that supplementing with EAAs improved endurance performance in trained cyclists. 3
4. Maintenance of Muscle
Various studies reveal that supplementing 6gm of EAAs possesses a compelling muscle- preserving effect.
One study published in the American Journal of Clinical Nutrition found that supplementing with EAAs helped to preserve muscle mass in healthy older adults. The study concluded that “supplemental EAA intake acutely stimulates muscle protein synthesis in healthy elderly adults and helps preserve muscle mass”. 4
Another study published in the Journal of Nutrition found that supplementing with EAAs during periods of immobilization helped to preserve muscle mass and function in healthy young adults. The study concluded that “supplementing with essential amino acids during a short period of muscle disuse preserves muscle mass and function”. 5
5. Appetite Regulation
EAA’s possess a special ability to regulate appetite by activating the brain cells that suppress hunger and improve satiety which is extremely crucial for a fitness seeker.
One study published in the journal Nutrition and Metabolism found that supplementing with EAAs decreased levels of the hunger hormone ghrelin and increased levels of the satiety hormone leptin in healthy young adults. The study concluded that “the present data suggest that EAA supplementation may be effective in regulating appetite through modifying the secretion of hunger and satiety hormones”. 6
Another study published in the journal Appetite found that supplementing with EAAs decreased food intake in overweight individuals. The study concluded that “EAA supplementation may be a novel approach to decreasing food intake and promoting weight loss in overweight adults”. 7

What happens if you take too many EAAs?
When excessive amounts of amino acids are taken, catabolism by enzymes in the liver and elsewhere is accelerated when intake exceeds requirements. In addition, changes in the free amino acid levels in the brain signal the nervous system centers regulating food consumption, and eating patterns are affected.
When should I take the ultimate EAA?
EAAs Are Effective Pre- and Post-Workout
Whether you’re walking, cycling, running stairs, or jumping rope, start by taking your EAA supplement 30 minutes before your workout session. The biggest benefit comes when you take your EAA supplement within an hour after your workout when your blood flow is strong and active
Should I take amino acids in the morning or at night?
Protein ingested immediately prior to sleep is effectively digested and absorbed, thereby increasing amino acid availability during overnight sleep. Greater amino acid availability during sleep stimulates muscle protein synthesis rates and improves whole-body protein net balance during overnight recovery.
What happens if you take amino acids every day?
Amino acids, specifically, are generally safe to use every day, as long as they’re not consumed in huge amounts. Because the nutritional needs of different people can vary widely, it’s tough to say exactly what the upper limit might be for amino acids in general.
Does EAA have side effects?
According to scientific research, there are no known serious side effects have been reported when using an EAA supplement in both normal and high amounts.
Who should not take amino acids?
Three of the most commonly mentioned risks of long-term amino acid supplementation are nausea, headache, and pain. Amino acid supplements can impact your blood sugar levels. This means that you should avoid them before and after surgery. Many experts advise against taking supplements that contain a single amino acid.
What amino acids should not be taken together?
L-lysine, for example, competes for cell receptors with L-arginine, so they’re best used separately. Other amino acids that shouldn’t be combined are tryptophan and phenylalanine or tyrosine, taurine, and glutamic acid or aspartic acid, carnitine and tyrosine, and cysteine and lysine.
