What are amino acids?

Amino acids are the building blocks of the body. They help create the proteins you need to survive. On a cellular level, they are the most important part of the body. There are 20 amino acids that are broken into 2 categories; essential and non-essential. The reason behind the name Essential in Amino acids is due to the body’s failure to produce them. Non-essential amino acids are made by the body, but they are just as important as the essential amino acids.

What are the Essential Amino Acids?

A large portion of our muscles, tissues, and cells are of amino acids. This has a crucial role in promoting the body’s capability to repair and refuel. EAA supplementation is a great solution for repairing and protecting the body during intense training. They work through encouraging growth, preventing muscle breakdown and improving energy.

The supplementation of EAA’s has become increasingly popular due to the average diet not consisting of enough EAA rich foods. The supplement has also been beneficial to athletes, through enhancing endurance throughout training and encouraging improved muscle recovery.

From energy production to immune function, each one of the essential amino acids plays a significant role in the body. 

A deficiency in amino acids can result in several issues; digestive problems, depression, decreased immunity, fertility issue, slowed growth in children and much more. Every one of the essential amino acids has a different yet important role in the body and deficiency symptoms will vary.

The Essential Amino Acids and what they do:


Lysine is the essential amino acid specialized in maintaining bone strength, building muscle, aiding recovery and regulating antibodies, enzymes, and hormones. Some research has shown that a deficiency in lysine can cause stress induces anxiety. 


Histidine promotes tissue repair, growth and the creation of blood cells. This amino acids also maintains the protective layer covering nerve cells; the myelin sheath.


Threonine’s job is to aid fat metabolism and help people with anxiety, indigestion, and depression. Threonine is also an essential component for healthy teeth and skin.


Methionine together with the help of non-essential amino acid Cysteine, improve the health of hair, skin, and nails. 


The amino acid Valine improves muscle growth, tissue repair, and energy, as well as muscle coordination and mental focus. A deficiency in Valine can lead to insomnia and a reduction in mental functionality.


Isoleucine is mainly found in muscle tissue as it regulates energy levels. It helps with immunity, blood sugar regulation, wound healing and hormone production. A deficiency in Isoleucine is more often seen in older adults and causes muscle wasting and shaking. 


The amino acid Leucine is key for wound healing and growth hormone production. Leucine regulates blood sugar levels and helps with the repair and growth of muscle and bone.


Phenylalanine is an amino acid that helps the body to use other amino acids along with protein and enzymes. A deficiency in this amino acid is rare, though can cause weight gain in infants and cause fatigue and eczema in adults and children.


Tryptophan is key to good growth in infants and is the messenger of serotonin and melatonin. Serotonin regulates sleep, mood, appetite, and pain. Melatonin regulates sleep as well. A deficiency in Tryptophan can lead to pellagra, a condition that can cause skin rashes, digestive issues, and dementia.
