USP Labs Jack3d Advanced 248g with raspberry flavour

Dietary supplement USP Labs Jack3d Advanced 248g with raspberry flavour is a concentrated product containing L-citrulline, beta-alanine in the form of CarnoSyn, creatine monohydrate, and anhydrous creatine, tyrosine, choline, caffeine, as well as pine bark extract.

Citrulline is a derivative of ornithine, also an alpha amino acid, involved in the urea cycle.

Beta-alanine is also a non-protein amino acid produced in the liver. This compound increases the concentration of carnosine in muscles, hence the form CarnoSyn. Beta-alanine thus acts as an intracellular pH buffer. This helps prevent rapid muscle fatigue and the onset of acidosis, commonly known as "burning" sensation. [1]

Creatine is an organic compound present in muscles and tendons. It influences muscle strength and enhances physical performance during short-term, repetitive high-intensity exercises [ID 739]. Studies have shown that creatine can not only improve exercise efficiency but may also play a role in preventing or reducing the severity of injuries, aiding rehabilitation after injuries, and helping athletes tolerate high training loads. [2]

Tyrosine is an organic compound from the amino acid group. Its primary function is intracellular signalling. Additionally, it serves as a precursor for the synthesis of several important substances, such as hormones - thyroxine and triiodothyronine, and catecholamines - noradrenaline, adrenaline, and dopamine.

Choline is a substance that maintains proper liver function [ID 712] by metabolising fats, facilitating digestion. It also participates in homocysteine metabolism [ID 3090].

Caffeine is a purine alkaloid - an organic chemical compound found in large quantities in coffee beans. It exhibits a range of effects on the body. Primarily, it increases alertness and attention [ID 736]. It also contributes to increased endurance and reduces perceived fatigue during intense physical activity. Most importantly, it enhances performance during activity [ID 737].

Pine bark extract is found in the climatic zone around the Mediterranean Sea. The components in the extract from this tree's bark exhibit antioxidant activity. They protect DNA, proteins, and lipids from damage caused by oxidative stress [ID 3505]. Furthermore, they help improve microcirculation and protect the delicate walls of blood vessels from damage.

In summary, USP Labs Jack3d Advanced 248g with raspberry flavour is a comprehensive dietary supplement providing essential ingredients for active muscles. It is especially recommended to be taken before training to maximise performance.
