Uncover the Best Australian Online Supplements in Our Range of Amino Acids!

Many athletes do not only use protein powder to get valuable amino acids in their body, because they can also get them from pure Australian online supplements that only contain individual amino acids. To find out more about these specific Australian online supplements, and discover the benefits they can provide, please discover our recommended amino acids below.

Branched Chain Amino Acids (BCAA’s)

The BCAA’s can be found in many Australian online supplements. Most BCAA’s can be found in protein powder, but if you want an even higher concentration, this supplement from our Australian online supplements range may be your best option.

Our BCAA’s supplement provides athletes with all branched chain amino acids that can be found in most protein powders; this includes leucine, isoleucine and valine. The supplement contains double the amount of leucine compared to isoleucine and valine, since this is the most optimal BCAA ratio for athletes. If you want to benefit from increased sports performance, muscle building and endurance, but want to try something different than a protein powder, then you may want to try this alternative to regular protein powder from our Australian online supplements range.


L-arginine is a popular supplement amongst trainers and experienced athletes, since this amino acid plays a crucial role in the synthesis of nitic oxide, a substance responsible for the widening of the blood vessels and the increase of muscle pump after rigorous training sessions. In addition to these benefits, L-arginine has also shown to provide athletes with more energy, strength and endurance, which makes this a popular supplement for anyone wanting to improve their sports performance.

Glutamine Peptides

Glutamine Peptides are suitable to increase your sports performance, muscle building abilities and your endurance. It is a combination of the amino acid glutamine, which forms a bond with other important amino acids through peptides. The combination allows athletes to absorb these substances in the body better, mainly due to a more stable chemical structure.

The use of Glutamine Peptides has shown some specific benefits during scientific studies as well. Test subjects on glutamine peptides experienced a faster recovery after rigorous workouts, improved performance in the gym, and an increase in lean muscle mass by supporting protein synthesis.

Acetyl L-Carnitine

Acetyl L-Carnitine is a unique version of L-Carnitine. The supplement is characterised by a high bioavailability, which means athletes will have less problems digesting and absorbing this supplement compared to normal L-carnitine.

The supplement Acetyl L-Carnitine is mainly used for weight loss purposes. The amino acid is responsible for the transportation of specific fatty acids to the mitochondria of the cells. Once the fatty acids arrive in the cells, they are converted into energy. Later, that energy gets converted in adenosine triphosphate, a valuable substance used in protein synthesis.

In addition to energy conversion, Acetyl L-Carnitine is also used to regular blood sugar levels. Even when you had a little more carbohydrates than you should have, the amino acid will keep your blood sugar levels balanced and prevent the so-called energy dip.

Essential Amino Acids (EAA’s)

EAA’s fulfil numerous functions in the human body, so it is no surprise that this supplement can provide various benefits for your physical fitness. EAA’s are used by athletes for weight loss, sports performance, muscle building, health & wellbeing and endurance.

The EEA’s cannot be made by the human body itself, which is why athletes need to obtain it from food or supplements. Considering many of these amino acids play a crucial role in muscle building and enhance your sports performance, getting these substances in your diet is an essential part of your training routine.

Nutrients Direct uses a proprietary blend of EEA’s, which includes leucine, lysine, valine, threonine, isoleucine, methionine, phenylalanine, histidine and tryptophan. The EEA’s are balanced, so they provide the optimal ratio for both trainers and experienced athletes.

Arginine Alpha Ketogluterate (AAKG)

Arginine Alpha Ketogluterate or AAKG is a known bulking agent, which can also be used to enhance your sports performance or increase lean muscle mass. It is also a popular ingredient in pre-workout supplements, since this supplement can increase the delivery of L-arginine to muscle cells and increase the intensity and duration of muscle pump.

AAKG supplements also have anti-catabolic properties, which means they will prevent the breakdown of muscle and create an optimal environment for muscle building. Therefore, Arginine Alpha Ketogluterate is a popular supplement amongst athletes focussed on muscle building and bulking up.


Aside from Creatine, Beta-Alanine is probably one of the best-known amino acid supplements in Australia. The supplement is used to boost the synthesis of carnosine in the body, a substance found in the muscles.

Carnosine is a peptide that protects the muscle against the build-up of hydrogen. When you do intensive exercise, the body starts to pile up hydrogen ions in the muscle. When the level of hydrogen gets too high, the PH value of the muscle cells gets too low. Subsequently, the athletes will start to experience muscle fatigue and will not be able to get the most from their training.
