THE KEY XPEDITE INGREDIENTS AND REFERENCES

R-LIPOIC ACID JUMPSTARTS ENERGY FOR WORKOUTS

XPEDITE contains a potent ingredient called R-Lipoic Acid or R-LA, which is not included in the lion’s share of the pre-workout/energy products available. Some researchers believe R-LA may eventually be acknowledged as one of the most important nutraceutical compounds on the market for cellular energy production. R-Lipoic acid has properties that make it especially valuable for athletes. It improves the body’s utilization of glucose and may increase the body’s production of adenosine triphosphate (ATP) within the muscle cells.

Mitochondria produces most of the cellular energy used by the body and R-LA is the only form of lipoic acid that functions as a cofactor for mitochondrial enzymes. Although R-LA is a more expensive form, it has been shown to be many times more effective than the more commonly used racemic alpha lipoic acid or ALA. It’s equally important to note that R-LA improves insulin sensitivity and accelerates the metabolic rate, which may help reduce the gain in body fat with aging (1, 2).  

R-LA is more commonly known for its powerful and universal antioxidant functions since it is both water and fat soluble. R-LA also increases or maintains the levels of other potent antioxidants including coenzyme Q10, vitamin C, vitamin E and glutathione (3-5). Anyone who does intense exercise needs to take powerful antioxidants to combat the free radical damage from the oxidative stress and to facilitate muscle recovery.

Additionally, biotin is included in the XPEDITE formula because it enhances the absorption of R-LA. Biotin is a natural co-factor that compliments R-LA in promoting cellular energy for muscular endurance and improved workout performance. Likewise, this scientific formula contains both taurine and L-carnitine, which further supports the optimal blood sugar levels needed during high-intensity exercise. As a bonus, these ingredients support fat loss by increasing glucose uptake by muscle tissue, which helps to prevent fat cell deposition.

TYROSINE ENHANCES COGNITIVE FUNCTION

XPEDITE contains the amino acid tyrosine, which is a precursor of the brain neurotransmitters epinephrine (adrenalin), norepinephrine and dopamine, which transmit nerve impulses. Dopamine is vital to mental function. U.S. soldiers undergoing various psychological and physiological stress tests were given tyrosine to measure its effects on performance. The researchers found that the soldiers who took tyrosine performed significantly better on a variety of tests compared to those who took a placebo. They were more efficient, alert and had faster reaction times (6). Studies have also shown that tyrosine can considerably reduce fatigue, muscular discomfort and sleepiness (7, 8).

L-CARNITINE L-TARTRATE IMPROVES VO2MAX AND EXERCISE RECOVERY

There is a lot of research examining the potential of carnitine supplementation to spare muscle glycogen and improve exercise performance (9, 10). The L-carnitine L-tartrate form contained in XPEDITE has been found to effectively assist in muscle recovery from high-repetition squat exercise. Researchers found the beneficial effects of carnitine on exercise recovery responses to include improved blood flow and reduced free radical formation, tissue damage and muscle soreness (11).

The positive effects of carnitine on aerobic work capacity or VO2 max has also been demonstrated in studies involving various types of athletes (12, 13). One of the consequences of high-intensity training is hypoxia (low blood oxygen), which increases the concentration of the metabolic waste byproduct ammonia (14). Ammonia accumulation is associated with muscle fatigue and L-carnitine L-tartrate has been found to decrease athletes’ ammonia levels in a well controlled study (15).
