Essential Amino Acids (EAA) are required by the body to help build new tissue and aid muscle repair. They are deemed 'essential' since ultimately they cannot be synthesised or created by the body and therefore the only way we can get them is through the foods we eat and supplements we take.

What Are Essential Amino Acids?

Essential Amino Acids (EAA) are required by the body to help build new tissue and aid muscle repair. Essential Amino Acids are deemed 'essential' since ultimately they cannot be synthesised or created by the body and therefore the only way we can get them is through the foods we eat and supplements we take.

What's The Best Essential Amino Acid Powder?

The Protein Works™ Essential Amino Acids contains all 9 of the essential amino acids uses only premium grade ingredients to create the finest quality supplement, backed up with the very latest Certificate of Analysis.

What Are The Benefits of Essential Amino Acids Supplements?

Adding Essential Amino Acids as a supplement to your diet helps the body to extract the maximum amount of nutrients from protein sources. This is turn helps you to train harder and for longer while the body will also be able to recover more quickly. Whilst experts believe a normal, healthy diet is sufficient to supply most people with all the amino acids they need, athletes and those involved in heavy training are believed to have a far elevated need for Essential Amino Acids to help the growth and repair of cells within the body. In these groups, Essential Amino Acids supplementation has been shown to produce favourable changes in muscle protein synthesis, muscle mass, and ultimately functional outcomes such as muscle strength and endurance.

A daily intake for me. A backup just to make sure I don't miss anything.
If one of the essential amino acids is less than needed for an individual the utilization of other amino acids will be hindered and thus protein synthesis will be less than what it usually is (Wiki). This product has all nine Essential Amino Acids, need I say more.

Good Product - Bad Taste
Use my referral code for FREE protein!


I recently bought these EAA's and selected unflavoured' so that I could add them to my protein shake. Unfortunately, this is NOT unflavoured! They do have a very strong taste and to be honest it's disgusting! It totally overpowers the taste of the shake and it makes my mouth tingle; my face actually hurts every time I drink it!

Aside from the nasty taste of the unflavoured variety, Id say they are doing a good job and they are certainly helping me. However, in future I think I'll choose the flavoured option and drink it with juice!

Great product
This product is amazing! I've never had EAA's before as I usually go for BCAA's - I have noticed a big difference in recovery time and hardly get any muscle pain after training now. People have complained about the taste but I mix mines with my berry blitz flavoured creatine and lots of water and dont notice any bad taste. Highly recommended.
