Scientific research demonstrates that citicoline consumption helps to improve focus and mental alertness by enhancing the synthesis of acetylcholine and norepinephrine and regulating neuronal membrane excitability. It has been shown to be especially helpful in conditions of high oxygen demand (as during intense training).
This conditionally essential amino acid is a precursor to the vitally important catecholamines (epinephrine, norepinephrine and dopamine) involved in the regulation of neuromuscular performance, focus, and alertness. By replenishing the catecholamines that are used for energy by fast acting caffeine, L-tyrosine has been shown to help prevent and/or significantly delay mental and physical fatigue during exercise.
This incredible preworkout compound acts as a shuttle for fatty acids into the mitochondria of muscle cells for energy production. It can also donate its acetyl group to form acetyl-CoA, the most important intermediary in the generation of energy from amino acids, fats, and carbohydrates.
Has the ability to combat exercise-induced stress by blunting cortisol release during training. By minimizing the amounts of this catabolic hormone, PS can delay fatigue and preserve peak performance longer.
Research now shows that lactic acid is NOT the only contributor to fatigue during exercise. Hydrogen ion accumulation is perhaps just as disabling. That said, by promoting high levels of intramuscular carnosine (a known lactic acid buffer and H+ ion neutralizer), Beta-Alanine supplementation can significantly delay fatigue and extend muscle power output.
Brand new studies suggest that Taurine is the most abundant amino acid in the body (above glutamine), particularly in the power generating type II fibers. Through supplementation it is possible to maintain peak stores of this important nutrient to enable more consistent force production without energy dropoff. Long term, taurine has been shown to be a cell volumizer that boosts internal muscle hydration...resulting in higher rates of muscle growth and function.
Green Tea Extract promotes natural energy by assisting in the breakdown of dietary fats and sugars. Through its active ingredient, EGCG, a single dose of Green tea has been shown to increase metabolic rate significantly when compared to placebo.
Caffeine is a widely used stimulant which is well studied and known to be safe in dosages of up to 500-600 mg. X-Cite provides the perfect blend of natural anhydrous caffeine and its herbal relative guarana, to produce unparalleled mental alertness and energy without the jitters or dangerous side effects of other popular preworkout stimulants.
L-carnitine has the ability to transfer long-chain fatty acids, such as triglycerides in the blood, into mitochondria (a cell's energy powerhouse), where they are oxidized to produce energy. Through consistent use, it has also been shown to reduce fat mass, increase lean muscle, and improve neurotransmitter function in the brain.
If caffeine is the source of energy, think of your B-vitamins as the gatekeepers that control the flow and duration of energy. B-3, B-12, and their chemical relatives are involved in the majority of all metabolic reactions. Their deficiency can put a definite limit on both the amount and time that you can experience peak energy.
BCAA’s are one of the most overlooked pre-workout supplement additions. They serve the dual purpose of providing immediate energy (as they’re already in their metabolized form) and setting the stage for immediate anabolic muscle restructuring following your workout.
Arginine and A-AKG are precursors to Nitric Oxide, a known vasodilator and free radical scavenger. Outside of the increased muscle pump effect that is of very little value to performance, these precursors can promote increases in oxygen flow to the working muscles to produce more immediate and sustainable energy during activity. Long term, this positive blood flow produces a more anabolic environment for muscle growth and fat metabolism.
Glycine has powerful antioxidant benefits against superoxide radicals. It plays an important role in energy production by acting as a vehicle for the transport of fatty acids into the mitochondria where they can be used for immediate energy.
Water alone is not enough to prevent dehydration during intense activity. Electrolytes are needed to maintain proper fluid balance inside and outside the working cells to ensure that the muscles can operate in ideal chemical environment.
