More Information:
Redpoint Nutrition scientifically formulated CRANK Forearm Fuel™ to improve your climbing performance in three distinct ways:
Delay the onset and reduce the severity of muscle fatigue: Lack of sufficient, available fuel at the cellular level is one of the primary causes of muscular fatigue. This leads to increased acidity, or acidosis, in the muscles and results in the "burn" or "pump" you feel in your forearms. By supplying a readily-available source of fuel to working muscles, CRANK Forearm Fuel™ helps delay the onset and severity of muscular fatigue.
Speed recovery between intense efforts: Faster and more complete recovery between climbs means you'll perform at a higher level for longer. CRANK Forearm Fuel™ helps speed the replenishment of muscle energy stores between intense physical efforts.
Reduce and repair exercise-related cellular damage: In order to get stronger and to avoid injury you have to limit the damage caused by hard climbing or training days and ensure your body has what it needs to fully repair exercise-induced cellular damage. CRANK Forearm Fuel™ contains natural antioxidants and other ingredients shown to be cytoprotective.
Ingredient Overview:
LACTATE provides an important and efficient source of fuel for working muscles. Lactate ingestion improves endurance by buffering the blood against fatigue-inducing acidosis (the “burn” or “pump”) and sparing glycogen stores in the muscle. [1,2,3,4,5,6,7]
CITRULLINE MALATE speeds recovery and reduces fatigue by enhancing the fueling impact of lactate supplementation and by helping clear fatigue-causing byproducts of intense muscular effort. [8,9,10,11,12,31]
GINSENG AND GREEN TEA EXTRACT enhances mental acuity and physical stamina and improves endurance by increasing fat utilization as a fuel for working muscles. [16,17,18,19,20,21,22,23,24,25,26,27,28,29,30]
TAURINE improves cardiac output, enhances exercise performance, and reduces oxidative damage of skeletal muscles. [13,14,15]
VITAMIN D promotes calcium absorption for proper muscle function and protects against muscle weakness.
VITAMIN B COMPLEX enhances metabolic rate and maintains healthy muscles.
