Alpha-GPC – Everything You Need To Know

α-GPC (also referred to as Choline alphoscerate or L-alpha-glycerylphosphorylcholine) is a natural choline compound found in the brain. It is considered a parasympathetic agent and is commonly taken as a supplement for its potential cognitive and performance-enhancing effects. Cognition When ingested, it is easily absorbed and crosses the blood-brain barrier which is then metabolized into choline. Choline is a precursor to the neurotransmitter, acetylcholine, which facilitates learning, memory, and focus.

Arginine Alpha-Ketoglutarate (AAKG) – Is it Worth Taking?

Arginine Alpha-Ketoglutarate (AAKG) – Is it Worth Taking?

Arginine alpha-ketoglutarate (AAKG) is a supplement that combines the amino acid arginine with alpha-ketoglutarate (AKG). Arginine is an amino acid that plays an important role in the urea cycle and is involved in nitric oxide production, which is what it is known for in the performance space. On its own though, the absorption of arginine is quite low. AKG plays a role in metabolism by regulating energy production through the Krebs cycle, the process through which cells generate energy in the form of ATP. By combining arginine with alpha-ketoglutarate, the aim is to potentially enhance the delivery of arginine to…

Why Are Carbohydrates Important for CrossFit?

Why Are Carbohydrates Important for CrossFit?

CrossFit is a branded fitness program that involves ‘constantly varied functional movements performed at high intensity.’ In a nutshell, the answer to why carbohydrates are so crucial for CrossFit comes down to human physiology and the energy systems predominantly involved in this type of training.  Carbohydrates  Carbohydrates are made up of starches, sugars and cellulose. Once digested, they are broken down into single sugar molecules in the form of glucose. This can then be stored in the muscle and liver as glycogen, ready to be used as a quick energy source.  Examples of carbohydrate-rich foods: Bread, bread rolls, wraps Pasta,…
