Foods high in essential amino acids

Essential Amino Acids

Amino acid definition:

Amino acids, commonly referred to as the building blocks of proteins, are chemicals that play many critical roles in your body.

They are required for vital processes like the construction of proteins and the absorption of hormones and neurotransmitters.

Some might also be taken in supplement form for a natural approach to boost athletic performance or enhance mood.

They’re categorized as essential, conditionally essential, or nonessential depending on several factors.

This report tells you all you need to know about essential amino acids, such as the way they function, possible food sources, and the benefits of choosing a nutritional supplement.

Which Are Essential Amino Acids?

Amino acids are organic compounds composed of nitrogen, carbon, hydrogen, and oxygen, together with a variable side chain collection.

Your body needs 20 different amino acids to grow and function correctly. Though all 20 of them are important for your health, only nine amino acids are classified as essential.

Unlike nonessential amino acids, essential amino acids can not be produced by the human body and must be obtained through your diet plan.

The very top sources of essential amino acids are animal proteins like meat, eggs, and poultry.

If you eat protein, then it’s broken down into amino acids, which are subsequently used to assist your body with numerous processes like building muscle building and regulating immune functioning.

There are numerous nonessential amino acids that are classified as conditionally essential.

These are considered to be essential only under certain circumstances like illness or anxiety.

By way of example, though arginine is deemed nonessential, the human body can not meet demands when fighting certain diseases like cancer…

That’s why arginine has to be supplemented through diet so as to satisfy your body’s needs in some specific scenarios.

Bottom Line:

The nine essential amino acids can not be produced by the human body and must be obtained through your diet.

Nine essential amino acids and their roles in your body:

They perform a number of important and varied jobs on your body:


Phenylalanine is a precursor for the neurotransmitters tyrosine, dopamine, epinephrine, and norepinephrine.

It plays an integral part in the structure and function of proteins and enzymes and the production of other amino acids.


A Valine is one of three branched-chain amino acids, meaning it’s a series branching off to one side of its molecular structure.

Valine helps stimulate muscle growth and regeneration and is involved in energy production.


Threonine is a principal portion of structural proteins such as elastin and collagen, which are important components of the skin and connective tissues.

Additionally, it plays a role in fat metabolism and immune function.


Though frequently associated with causing nausea, tryptophan has lots of different purposes.

It is required to maintain proper nitrogen balance and is a precursor to serotonin, a neurotransmitter that regulates your appetite, mood, and sleep.


Methionine plays a significant role in metabolism and detoxification.

Additionally, it is crucial for tissue growth and the absorption of selenium and zinc, minerals that are vital to your health.


Much like valine, leucine is a branched-chain amino acid that is critical for protein synthesis and muscle repair.

Additionally, it helps regulate blood sugar levels, stimulates wound healing, and produces growth hormones.


The final of those three branched-chain amino acids, isoleucine is included in muscle growth and is significantly concentrated in muscle tissue.

It’s also important for immune function, hemoglobin manufacturing, and energy regulation.


Lysine plays a major role in protein synthesis, hormone and enzyme production, and also the absorption of calcium.

It’s also critical for energy production, immune function, and the production of elastin and collagen.


Histidine is utilized to produce histamine, a neurotransmitter that’s vital to immune response, digestion, sexual function, and sleep-wake cycles.

It is essential for keeping the myelin sheath, a protective barrier which encircles your cells.

As you can see, essential amino acids are at the core of many vital processes.

Though they are recognized for their role in muscle development and repair, the human body is dependent on them for so much more.

That’s why essential amino acid deficiencies can negatively impact your whole body including your nervous, reproductive, immune, and digestive systems.

Bottom Line:

All nine essential amino acids play varied roles in the body. They are involved in important processes like tissue growth, energy production, immune function, and nutrient absorption.

Health Benefits of Supplementing With Vital Amino Acids:

While vital amino acids are seen in a wide selection of foods, taking concentrated doses in supplemental type was linked to several health benefits.

May Help Boost Mood and Sleep:

Tryptophan is needed for the production of serotonin, a compound that serves as a neurotransmitter in the human body.

Serotonin is a vital regulator of mood, sleep, and behaviors.

While low serotonin levels are linked to depressed mood and sleep disturbances, many studies have demonstrated that supplementing with tryptophan can lessen symptoms of depression, boost mood and enhance sleep.

A 19-day study in 60 older women found that 1 g of tryptophan per day led to increased energy and enhanced enjoyment, in comparison to a placebo.

Could Boost Exercise Performance:

The 3 branched-chain essential amino acids are frequently used to relieve fatigue, enhance athletic performance and stimulate muscle recovery following exercise.

In a study in 16 resistance-trained athletes, branched-chain amino acid supplements improved performance and muscle recovery and decreased muscle soreness, in comparison to a placebo.

Additionally, taking 4 grams of leucine per day for 12 weeks improved energy performance in untrained men, demonstrating that essential amino acids may benefit non-athletes too.

Can Avoid Muscle Loss:

Muscle reduction is a common complication of prolonged illnesses and bed rest, especially in elderly adults.

Vital amino acids are found to prevent muscle breakdown and preserve lean body mass.

10-day research in 22 elderly adults on bed rest revealed that those who obtained 15 grams of blended essential amino acids maintained muscle protein synthesis, whereas the procedure decreased by 30 percent in the placebo group.

The supplements also have been found to be effective in preserving lean body mass in elderly athletes and people.

Help Promote Weight Loss:

Some human and animal studies have shown that branched-chain crucial amino acids can be effective in stimulating fat reduction.

By way of instance, an eight-week study in 36 strength-trained men discovered that supplementing with 14 g of branched-chain amino acids per day significantly reduced body fat percent, compared to whey protein or a sports beverage.

A study in rats showed that a diet consisting of 4 percent supplemental leucine reduced body weight and fat.

However, other research investigating the possible connection between branched-chain acids and weight loss is inconsistent. More studies are required to decide if these amino acids can promote weight loss.

Bottom Line:

Supplementing with specific essential amino acids might help improve mood, improve exercise performance, prevent muscle loss and promote weight loss.

Food Resources and Recommended Intake:

Since your body cannot produce amino acids that are essential, they must be provided through your diet plan.

Fortunately, many meals are rich in it, making it easy to meet your everyday requirements.

The US recommended daily allowances every 2.2 pounds (1 kg) of body weight for the nine essential amino acids are:

  • Valine: 24 mg
  • Histidine: 14 mg
  • Isoleucine: 19 mg
  • Lysine: 38 mg
  • Leucine: 42 mg
  • Methionine (+ the non-essential amino acid cysteine): 19 mg
  • Phenylalanine (+ the non-essential amino acid tyrosine): 33 mg
  • Tryptophan: 5 milligrams
  • Threonine: 20 mg

Foods that contain all nine essential amino acids are also referred to as complete proteins.

Total protein resources include:
  • Meat
  • Seafood
  • Poultry
  • Eggs
  • Dairy Products

Soy, quinoa, and buckwheat are plant-based foods that contain all nine essential of it, making them total protein sources too.

Other plant-based sources of protein such as beans and nuts are deemed incomplete since they lack at least one of the essential amino acids.

But if you’re following a plant-based diet, then you may still ensure proper intake of all essential amino acids as long as you eat a variety of plant proteins every day.

For example, picking a variety of incomplete proteins such as beans, seeds, nuts, whole grains, and vegetables can make certain your crucial amino acid demands are met, even in the event that you opt to exclude animal products from your diet plan.

Bottom Line:

Both animal and plant products, such as eggs, poultry, quinoa, and soy, can contain all nine essential amino acids and are considered complete proteins.


They’re vital for purposes such as protein synthesis, tissue repair, and nutrient absorption.

Some might also prevent muscle loss and improve mood, sleep, athletic performance, and weight reduction.

Fortunately, these very important compounds are found in several animal- and plant-based foods, helping you meet your daily requirements through a healthy and balanced diet.

Ask your friends and loved ones for support.
