Vitamin B6

B6 is a water-soluble vitamin with over 100 enzyme reactions, mostly related to protein metabolism. Vitamin B6 also plays a role in neurotransmitter biosynthesis, gluconeogenesis and glycogenolysis, immune function, and hemoglobin formation. 


L-Carnitine is a potent nutritional supplement used to improve the function of mitochondria. L-Carnitine is recognized by the United Mitochondrial Disease,, as a first tire supplement that may be of benefit in improving mitochondria function.  L-Carnitine is often the foundation in “mitochondria cocktails” used by clinicians for mitochondria support.  L-Carnitine helps mitochondria improve the utilization of fat in the energy production process.  L-Carnitine has been shown to decrease fatigue and increase cognitive function in select populations.

Our study indicates that oral administration of levocarnitine produces a reduction of total fat mass, increases total muscular mass, and facilitates an increased capacity for physical and cognitive activity by reducing fatigue and improving cognitive functions.

Rhodiola rosea

Rhodiola, while new to the western world, has been used for centuries to reduce fatigue. This prized herbal extract well known in the Soviet Union was used to help improve the performance of Olympic athletes and trainees in their cosmonaut program.  Standardized extracts of Rhodiola, like those found in PERC, have been show to improve mental performance under stressful conditions. Rhodiola has even been shown to improve exercise endurance!

“...Typically generates no side effects, unlike traditional stimulants that possess addiction, tolerance and abuse potential, produce a negative effect on sleep structure, and cause rebound hypersomnolence or 'come down' effects.

Furthermore, single administration of these adaptogens effectively increases mental performance and physical working capacity in humans. R. rosea is the most active of the three plant adaptogens producing, within 30 min of administration, a stimulating effect that continues for at least 4-6 h.”

Grape Seed Extract

Grape seed extract is a powerful antioxidant whose health benefits were recognized as far back as ancient Greece. The National Institute of Health, National Center for Complementary and Integrative Health reports that Grape Seed Extract has antioxidants that help prevent injury from oxidative stress (reactive oxygen species).
