GU Roctane Ultra Endurance Electrolyte Capsules

Roctane Electrolyte Capsule can be used before, during, and after exercise. They can be used at 1-2 capsules/hour whenever electrolytes are needed to combat sweat loss. These capsules contain 140mg of sodium which is the primary electrolyte lost in sweat. They have magnesium needed for longer, more sustained efforts. Ginger helps to empty the stomach and vitamin B6 helps minimize nausea. Vitamin D is included to help increase athletic performance.

There are several reasons to replace electrolytes during exercise. One is to help maintain plasma volume which is depleted by sweating, another to prevent hyponatremia from over-ingestion of fluids during exercise. Sodium is the main electrolyte lost in sweat, and along with magnesium and chloride are the only electrolytes, according to the folks at GU, with scientific data supporting the need for replacement during exercise.

GU includes vitamin D because Vitamin D is important for calcium absorption and bone health. Low levels of vitamin D are associated with deceased exercise performance. Despite hours of training in the sun many athletes are still vitamin D deficient, making this vitamin an important supplement for health and performance. Vitamin B6 is a water-soluble vitamin, and has been shown to significantly decrease nausea and vomiting. Ginger can decrease nausea and may boost the rate at which food can be emptied by the stomach. This may help prevent an upset stomach, bloating and nausea during hard training and racing.

Each capsule has 140mg sodium, 9mg magnesium, 1mg B6, 75iu vitamin D and 50mg ginger root powder.
