The fundamentals of essential amino acids (EAAs)

The fundamentals of essential amino acids (EAAs)

What are Amino Acids?

Amino Acids are the building blocks of protein and assist with building and repairing muscle and other important physiological functions. They are organic compounds composed of nitrogen, carbon, hydrogen and oxygen, along with a variable side chain group.

There are 20 Amino Acids that your body needs to function properly. Only eleven of those Amino Acids occur in the body naturally, they are non-essential Amino Acids. The other nine Amino Acids (Essential Amino Acids) need to be ingested by either supplementation, or through food.

Why do you need Amino Acids?

Amino Acids help the body perform various functions including protein synthesis, calcium absorption, skin elasticity, sleep and hormone regulation, to name a few. They also boost your immune system and help the body fight diseases.

USN ALL9™ AMINO can benefit any exercise regime:

There is no specific demographic that is outside the scope of the USN ALL9™ AMINO product. Users include, but are not limited to:

• Weight training and explosive sport athletes (general weight training, bodybuilding, sprinters, rugby players etc.).

• Endurance athletes (long distance runners, cyclists, triathlon runners, soccer players and swimmers).

• Day-to-day wellness (everyday inactive/moderately active people).

• Injured or rehab athletes.

How can supplementation with USN ALL9™ AMINO be beneficial?

Looking through the list of EAAs and their sources, it would take a lot of time planning, measuring and preparing these specific meals. It is also not always the most economic option to purchase all these ingredients separately. The easiest way to get a consolidated, convenient and precision dosed Essential Amino Acid intake, is through USN ALL9™ AMINO.

3 Myths surrounding Amino Acids

• “Essential Amino Acids can only be found in meat or animal protein” – This has been proven false as countless studies show that plant protein is just as complete as animal-based protein. Amino Acids can also be found in plant and nut sources.

• “Your body is able to produce all the needed Amino Acids” – Your body can only produce 11 of the 20 required Amino Acids. The other 9 need to be taken in via diet or supplementation.

• “Amino Acids cause gastrointestinal discomfort” – The USN ALL9™ AMINO includes AstraGin™ which promotes gastrointestinal health and enhances nutrient absorption. By adhering to the recommended serving size, no GI discomfort should be experienced.

Get to know the different Essential Amino Acids and their functions

• Histidine – Vital to immune response, digestion, sexual function and sleep-wake cycles. It’s critical for maintaining the myelin sheath, a protective barrier that surrounds your nerve cells.

• Isoleucine – The last of the three branched-chain Amino Acids, isoleucine is involved in muscle metabolism and is heavily concentrated in muscle tissue. It’s also important for immune function, haemoglobin production and energy regulation.

• Leucine – Critical for protein synthesis and muscle repair. It also helps regulate blood sugar levels, stimulates wound healing and produces growth hormones.

• Phenylalanine – plays an integral role in the structure and function of proteins and enzymes and the production of other Amino Acids.

• Methionine – Methionine plays an important role in metabolism and detoxification. It’s also necessary for tissue growth and the absorption of zinc and selenium, minerals that are vital to your health.

• Lysine – Lysine plays major roles in protein synthesis, hormone and enzyme production and the absorption of calcium. It’s also important for energy production, immune function and the production of collagen and elastin

• Threonine – Threonine is a principal part of structural proteins such as collagen and elastin, which are important components of the skin and connective tissue. It also plays a role in fat metabolism and immune function.

• Tryptophan – Needed to maintain proper nitrogen balance and is a precursor to serotonin, a neurotransmitter that regulates your appetite, sleep and mood.

• Valine – Valine is one of three branched-chain Amino Acids, meaning it has a chain branching off to one side of its molecular structure. Valine helps stimulate muscle growth and regeneration and is involved in energy production.


Amino Acids form an important part of our dietary needs. The benefits of Amino Acids are vast and USN ALL9™ AMINO is an easy way to ensure that you reap the benefits of complete Amino Acid supplementation. It is also important to ensure that the right combination of protein is taken with the USN ALL9™ AMINO when leading an active lifestyle. USN ALL9™ AMINO should not replace a varied, balanced diet and an active lifestyle.
