Know the Role of Amino Acids in the Body

Proteins are made up of molecules called amino acids, which are also known as the “building blocks of proteins,” play a variety of vital functions in your body. However, you should know the role of amino acids in the body. You require amino acids for essential functions like producing hormones, neurotransmitters, and proteins. In foods high in protein like meat, fish, and soybeans, amino acids are concentrated. Some people also take specific amino acids as supplements as a natural means of enhancing mood or athletic performance. Depending on a number of variables, they can be classified as essential, conditionally essential, or nonessential. A crucial component of repair, growth, and adaptation is the delivery of amino acids to the appropriate locations.

You can learn everything there is to know about essential amino acids in this article, including how they work, food sources that are high in them, and the possible advantages of taking a supplement.

What are amino acids and what is role of amino acids in the body?

Amino acids are thought of as the components that make up proteins. For example, they are a major component of your muscles and tissues, and foods high in protein like meat, fish (fatty acids), poultry, and eggs are made up of a variety of different amino acids. Twenty different amino acids are required by the body to maintain health and normal function. Nine of these amino acids are known as the essential amino acids. The other eleven amino acids can be produced by a healthy body, so they are typically not required to be consumed through diet.

All amino acids has a unique function in the body and can be identified by its side chains. These amino acids are involved in almost every biological process and aid in wound healing, hormone production, immune function, muscle growth, energy production and more.

What are essential amino acids?

Twenty different amino acids are crucial for your health, but only nine are considered to be absolutely necessary. These are only necessary in certain situations, such as during illness, pregnancy, early childhood, or trauma. While your body can produce non-essential amino acids, it is unable to produce essential amino acids; therefore, you must obtain them through diet.

Animal proteins like meat, eggs, and poultry are the best sources of essential amino acids. But some plant foods, like edamame and tofu made from soy, do contain all nine essential amino acids.

How many different types of amino acids are there?

Your body requires a total of twenty amino acids, which can be further broken down into essential amino acids and non-essential amino acids.

Essential amino acids: Your body is unable to produce essential amino acids, you must obtain them from food sources.

There are nine essential amino acids, each of which performs a number of important jobs in your body:

  • Lysine – maintaining bone density, constructing muscle, speeding up recovery from surgery or injury, and controlling hormones, antibodies, and enzymes.
  • Histidine: promotes tissue growth, blood cell production, and growth.
  • Threonine – essential for the maintenance of healthy skin, teeth and promotes fat metabolism.
  • Methionine – aids in the flexibility and health of skin and hair, along with the non-essential amino acid cysteine. Methionine also supports healthy, strong nails.
  • Valine – necessary for emotional stability, physical coordination, and mental clarity.
  • Isoleucine – aids in the production of hormones, blood sugar regulation, immunity, and wound healing. It controls energy levels and is mostly found in muscle tissue.
  • Leucine: promotes bone and muscle growth and repair while assisting in the control of blood sugar levels.
  • Phenylalanine – aids in the utilization of proteins, enzymes, and other amino acids by the body.
  • Tryptophan – it is a precursor to serotonin and melatonin and is essential for infants’ healthy development. A neurotransmitter called serotonin controls pain, mood, sleep, appetite, and sleep quality.

Non-essential amino acids: can be produced by your body, making it less necessary for you to consume them.

The list of non-essential amino acids consists of a total of eleven, including:

  • Arginine: Arginine improves heart health, fights fatigue, and stimulates immune function. Primarily with the aid of arginine, glycine, and methionine, creatine monohydrate is produced in the liver, pancreas, and kidneys.
  • Alanine: According to research, alanine helps with metabolism and gives the muscles, brain, and central nervous system energy.
  • Cysteine: The primary protein type in hair, skin, and nails, cysteine is essential for the development of collagen and the health of the skin.
  • Glutamate: In the central nervous system, this non-essential amino acid functions as a neurotransmitter.
  • Aspartate: Aspartate aids in the synthesis of asparagine, arginine, and lysine, among other amino acids.
  • Glycine: Glycine is a neurotransmitter that promotes the health of the brain.
  • Proline: Collagen contains proline, which supports skin elasticity, metabolism, and joint health.
  • Serine: Serine is essential for immune system health, muscle growth, and fat metabolism.
  • Tyrosine: Tyrosine aids in the synthesis of epinephrine, melanin, and thyroid hormones.
  • Glutamine: According to studies, glutamine supports a number of metabolic processes and gives the body’s cells energy.
  • Asparagine: Asparagine has diuretic properties and enhances brain and nerve cell performance.

What are health benefits of amino acid supplements?

While amino acids can be found in a wide array of foods. Taking concentrated doses in supplemental form has been linked to several health benefits, but check your doctor first.

1. May help with mood

An essential amino acid known as tryptophan is important for maintaining mental health and regulating mood. The body uses it to produce serotonin, a neurotransmitter thought to affect mood and behavior regulator.

2. May improve exercise performance and recovery

Boost Physical Performance Essential amino acids are unquestionably required whether you’re a casual gym goer or a competitive athlete if you want to advance your workout. In fact, as part of a nutritious post-workout meal, essential amino acids are frequently used to support muscle recovery, avoid soreness, and combat fatigue. Further, BCAA supplementation was able to lessen muscle soreness and enhance muscle function after strenuous workouts.

3. May be helpful for wound healing and surgery

Supplementing with amino acids may be beneficial for those recovering from surgery. Taking conditionally essential amino acids for two weeks after surgery led to lower rates of death and medical complications than those who received standard nutrition.

4. Improve weight loss

By accelerating fat loss and maintaining lean body mass, amino acids aid in weight loss. It has been demonstrated that adding branched-chain essential amino acids to a diet is particularly effective for promoting weight loss. Further, taking a supplement containing branched-chain amino acids (BCAAs) for 2-3 weeks may show greater reductions in body fat.

5. Preserve muscle mass

Amino acids are absolutely necessary for maintaining and growing muscles because they are the main components of muscle tissue. Additionally, some studies have shown that taking supplements of essential amino acids can help stop muscle loss, a common side effect of aging and weight loss. Moreover, more studies found that amino acids supplement provide improved muscle function for older adults on bed rest.

6. Sports performance

A high protein diet is frequently promoted to athletes along with amino acids. If you eat essential amino acids right before or right after exercise, your muscle growth might be increased. 

7. Blood glucose levels

Blood sugar levels have been shown to benefit from amino acids. Some type 2 diabetics who take amino acids can reduce their blood sugar levels without having an impact on their insulin levels.

8. Energy production for endurance athletes 

Taking an amino acid supplement can help with the production of mitochondria if you compete in an endurance sport. All of your cells’ energy is contained in these. You should be able to exert more effort while using the same amount of energy if you have more mitochondria.

9. Fatigue reduction

Some studies suggests taking an amino acid supplement can improve your ability to work through fatigue. Branch chain amino acids (BCAAs) may help with focus and improve energy while preventing fatigue because they can stop serotonin build-up in the brain, which causes a decline in drive and motivation.

10. Metabolic and digestive health aid

There is strong evidence that EAA supplementation can help and support both digestive and metabolic health, especially as you get older. A number of factors make amino acids more significant as you age. If insufficient amounts of amino acids are present from other sources, such as fats and carbohydrates, amino acids may be used as energy. This implies that they cannot be used for healing and growth.

11. Promote better sleep

Evidence suggests that tryptophan may help improve sleep quality and treat insomnia in addition to its potent mood-boosting effects. This is because it contributes to elevating serotonin levels, which are important for the sleep cycle. Tryptophan is not only well tolerated and linked to fewer side effects than many over-the-counter sleep aids, but it is also a fantastic natural sleep aid.

12. Boost skin health

Fibrous proteins, such as keratins, collagen, and elastin, make up the skin. Amino acids either with diet or supplement, play a part in the health and appearance of the skin because they are essential for the synthesis of these proteins. They help to retain more moisture, and can increase their muscle mass as well.

13. Low in calories

We are aware that calorie restriction is the best fat loss strategy currently available. Amino acids can be helpful if you’re trying to lose weight and cut back on calories. Because the energy has already been released from their bonds, they contain significantly fewer calories than other whole chain ergogenic aids.

14. Non-inflammatory

Since amino acids do not cause inflammation, they are a good choice for athletes who suffer from inflammatory disorders or underlying medical conditions. IBS, diabetes, allergies, asthma, autoimmune diseases, Crohn’s disease, and coeliac disease are a few examples of these. Whey proteins cause inflammation and are not well tolerated unless you are in excellent health.

15. Protect immune function

The human body needs a healthy immune system to function properly. When training volumes and intensities are increased, such as during intense training periods, this system is put at risk. The building blocks of all endocrine systems, important hormones, and substances are amino acids. Taking supplements can help prevent immune system deterioration during periods of intense training.

What foods are high in amino acids?

Proteins are created when amino acids combine. The following foods are complete protein sources:

Plant-based complete protein sources include soy and pea protein, and other plant-based protein sources, like beans, nuts, and some grains, are regarded as incomplete proteins since they are deficient in one or more essential amino acids. However, if you consume a variety of plant proteins every day while eating a plant-based diet, you can still make sure that you get enough of all nine essential amino acids.

What are signs of deficiency of amino acids?

Amino acid deficiency, also known as protein deficiency, happens when you don’t get enough amino acids in your diet to meet your requirements each day. Some of the top symptoms of an amino acid deficiency can include:

  • Dry skin
  • Splitting hair
  • Hair loss
  • Brittle nails
  • Thinning hair
  • Decreased muscle mass
  • Impaired growth in children
  • Increased appetite
  • Decreased immune function
  • Bone loss
  • Puffiness and swelling

What are risks and side effects of lack of amino acids?

Numerous aspects of health depend on essential amino acids, and a lack of these nutrients can result in a long list of severe side effects and symptoms. To avoid a deficiency and make sure you get enough, it’s important to eat a well-balanced diet that includes plenty of foods high in protein and other essential nutrients. It is unlikely that consuming large amounts of protein from food sources high in protein will have any negative side effects.

Protein overconsumption can have a number of negative side effects, such as weight gain, kidney problems, constipation, and bad breath. It is best to speak with your doctor if you experience any of these negative symptoms.

What is an amino acid supplement?

Most people consume adequate amounts of essential amino acids through diet, and it has some health advantages. However, they do not required supplements. There are numerous types of supplements that vary in the kinds they offer and the potential health advantages. Whey protein, hemp protein, and brown rice protein are just a few of the protein powder supplements that provide your body with many of the essential amino acids it requires while also providing a substantial amount of protein. Two additional simple options that can offer a good amount of protein as well as a variety of essential amino acids are collagen and protein powder made from bone broth.

You can also choose supplements that contain isolated amino acids like tryptophan, leucine, or lysine. All of these have been associated with particular health advantages and are frequently used as all-natural remedies for ailments like cold sores, depression, and insomnia. You need to make sure to carefully follow the dosage instructions to prevent unfavorable side effects, and speak with a reputable healthcare provider.


For good health, it is essential to consume essential amino acids. The best way for people to make sure they are getting enough of the essential amino acids is to eat a variety of protein-rich foods each day. Deficiency is uncommon for individuals who are generally in good health thanks to today’s modern diet and access to a wide variety of foods. Before using supplements, people should always consult a doctor.

If your body is deficient in one or more of the essential amino acids, you may benefit from taking an amino acid supplement. Your diet can be examined by a medical professional or nutritionist to determine whether you ought to think about taking amino acid supplements. Nausea, headaches, and pain are three of the most frequently mentioned risks of long-term amino acid supplementation. Always consult your doctor before taking an amino acid supplement.


What is the difference between essential and non-essential amino acids?

Your body is unable to produce on its own essential amino acids, however a diet must be consumed. Non-essential amino acids can be produced by the body and do not need to be consumed in sufficient amounts to support normal growth and function.

What are the benefits of amino acid supplements?

Aside from supporting muscle growth and repair, amino acid, supplements can also improve athletic performance, exercise recovery, promote brain function, and support weight loss. They are frequently used by bodybuilders, athletes, and people with special dietary requirements to support overall health and well-being and to guarantee an adequate intake of essential amino acids. A healthcare professional should be consulted before beginning any supplementation routine.
