Branched-chain amino acids are considered essential because your body cannot synthesize them. They must be obtained from dietary sources for normal physiological function. While food offers the best source of BCAAs, supplementation has been shown to increase endurance during exercise and improve muscle recovery after high-intensity training sessions.

6 G Citrulline Malate

Citrulline is an amino acid that has been shown to increase nitric oxide production, which enhances blood flow. Research suggests citrulline malate can delay mental fatigue and extend your ability to perform high-intensity exercise.

2 G Creatine HCI

Creatine HCl is a highly soluble form of creatine that has been clinically shown to increase physical performance in successive bursts of short-term, high-intensity exercise like weight training and sprinting/running. One study showed creatine HCl could help improve total workout volume, resulting in increased strength.

2 G Beta-Alanine

Beta-alanine is a naturally occurring beta-amino acid used in the biosynthesis of histidine, an amino acid that plays a role in the structure of hemoglobin. Studies have shown that beta-alanine supplementation can increase muscle carnosine levels, improving high-intensity exercise performance and delaying fatigue.

1,5 G Betaine

Betaine (trimethylglycine) is an osmolyte that has been shown to improve power output, enhance muscular endurance, and decrease muscle fatigue. It's also a methyl donor for the biosynthesis of several key compounds in the body.

More Energy During Workouts

Combining creatine HCl, beta-alanine, and L-citrulline malate in PRE JYM can enhance your energy levels during workouts by delaying mental fatigue and muscle failure. These effects are likely due to the "uncoupling" of the production of ATP (adenosine triphosphate). By uncoupling oxidative phosphorylation, more aerobic energy is produced through the glycolytic pathway, generating more adenosine triphosphate molecules per unit of time. This enables you to delay mental fatigue caused by an accumulation of hydrogen ions associated with muscle contraction so you can train harder for longer.

Enhanced Strength & Endurance Between Sets

Beta-alanine, creatine HCl and betaine are three key ingredients in PRE JYM that can enhance muscle strength during your workouts. By helping to maintain higher ATP production, beta-alanine enables you to train harder for longer. Creatine HCl has been shown to increase creatine levels within the muscle cells, giving you more energy to lift heavy weights. Finally, betaine also stimulates the body's production of insulin, which may increase intramuscular amino acid availability and support greater gains in strength and lean mass gains.

Better Focus

The combination of citrulline malate, beta-alanine, and creatine HCl in PRE JYM can improve your focus during workouts. Beta-alanine is a naturally occurring amino acid that plays a key role in muscle energy production. The synthesis of carnosine, an important buffer of excess hydrogen ions associated with physical exertion, depends on beta-alanine availability.

Citrulline acts as an ammonia scavenger to help maintain the optimal ammonia concentration in the blood at rest and during exercise. L-citrulline supplementation has been shown to support cardiovascular function by improving oxygen delivery to working muscles during exercise via enhanced circulation.

Creatine is essential for ATP production in the body to facilitate cellular energy. By loading the body with creatine through supplementation, you can increase your ability to train harder and longer.

Enhanced Recovery Between Workouts

Pre JYM contains two forms of branched-chain amino acids (BCAAs), leucine and isoleucine. These essential amino acids support protein synthesis and muscle recovery after workouts by reducing exercise-induced catabolism and promoting anabolic hormone secretion and blood flow.

For instance, one study showed that subjects supplementing with BCAAs experienced a 24% reduction in muscle damage markers following intense resistance training compared with subjects who did not ingest BCAA supplements. Subjects taking these BCAAs also had lower creatine kinase levels, a marker of muscle damage, and less soreness in the days following workouts. Plus, other studies have shown that leucine can increase protein synthesis and decrease protein breakdown after resistance training sessions.
