Performance Booster MET-Rx
Performance Booster

Performance Booster is uniquely formulated to contain vitamins, minerals and a combination of functional ingredients to meet your personal health and lifestyle goals of maximizing your workout.

BCAAs comprise a large percentage of the amino acid composition of muscle tissue and can be used for energy in muscle. BCAAs are the only aminos metabolized directly in the muscle as opposed to the liver.

L-Arginine is one of the 20 amino acids that plays an important role in human nutrition. Arginine is a popular ingredient in many top sports supplements.

L-Glutamine is the most concentrated free amino acid in blood and skeletal muscle. Glutamine can serve as an energy precursor and is involved in more metabolic processes than any other amino acid.

 Caffeine provides dual effects by providing energy magnification for both the mind and the body.

Electrolytes contain the electrolytes Calcium, Sodium and Magnesium. Electrolytes are important for helping to regulate nerve signals from the brain and spinal cord to muscles, and for regulating fluid balance. Replenish, rehydrate and refuel.

Vitamin C is a water soluble vitamin that provides superior antioxidant support to help fight free radicals. Free radicals can lead to oxidative stress and the premature aging of cells. Vitamin C also supports circulatory and immune system health and is even beneficial for your hair, skin and nails.

B12 assists energy metabolism in the body as well as circulatory and nervous system health.

B6 plays a role in energy metabolism by helping the body utilize BCAAs (branched chain amino acids).
