What are amino acids?

Amino acids occur naturally within protein, which supports the growth and maintenance of muscle mass — perfect for building muscle and maximising gains, making each and every training session worthwhile. There are nine essential amino acids. Leucine, isoleucine, and valine are three of these nine essential amino acids, and are commonly known as branched-chain amino acids, or BCAAs.


Benefits of amino acids

As amino acids are the building blocks of protein, they are great for supporting all fitness goals – whether that's maintaining your current fitness level or building all-important muscle. Amino acids can be quite difficult to get from your diet alone, not to mention expensive. That’s why our supplements can be such a time-saving and convenient way to get a boost of amino acids alongside a balanced diet.


Our amino acid supplements

We offer a huge variety of amino acid supplements for you to choose from to suit your individual needs and fitness goals. Our products come in a variety of forms, including tablets, gels, and drinks, making them an ideal convenient alternative for you to make part of a balanced diet. But, if you prefer to stick to a shake, we offer a wide range of refreshing flavours like tropical, cola and rainbow candy.

Our ultimate blend, Impact EAA, is crammed with all nine essential amino acids, with zero sugar* – perfect if you're following a specific diet:

• Contains all 9 essential amino acids

• Faster amino acid absorption than whey*

• Suitable for those following a plant-based diet

• Available in 3 refreshing flavours


For added electrolytes, try THE EAA:

• Superior blend of all nine essential amino acids

• Features 4.1g of BCAAs

• Great for an intra workout shake

• Contains 24mg of vitamin C**


Or, for convenience, have a look at 100% Beta Alanine Powder:

• Perfect to add to your daily protein shake

• Features 3g of beta alanine

• Ideal for sports which require explosive movements


If you are still unsure about which amino acid supplement is right for you, take a look at our ultimate breakdown of the best amino acids available.

FAQs


How many amino acids are there?

There are 22 amino acids with 9 of these being considered "essential" and the remainder "non-essential".


What are essential and non-essential amino acids?

When we use the word "essential" in reference to our diet, that means we're referring to something we cannot create ourselves. Non-essential simple means the body can create it itself and doesn't necessarily require a dietary source.


What do amino acids do?

Amino acids have a variety of unique functions but essentially are the building blocks of protein.


What is the best amino acid for building muscle?

Leucine is considered the "best" as it essentially acts as the "on-switch" for muscle protein synthesis, however, all amino acids have some role in the creation of new proteins.


Are amino acids from meat sources better?

The source is not important, only the completeness of the amino acid spectrum available.


Are amino acids water-soluble?

Yes, amino acids are generally water-soluble.


Can I have amino acids instead of a protein shake?

In theory yes, but the practicality of achieving a similar benefit makes it less time and cost-effective. You may find it easier to simply use a protein shake.
