GU Roctane Electrolyte Capsules - 125 Capsule Bottle

Roctane Electrolyte Capsules contain multiple essential electrolyte which your body must replenish during endurance activities: sodium, magnesium and chloride. Roctane Electrolyte Capsules help to fill in the gaps with sweat loss that is unique to each athlete. Also included is Ginger Root which can help decrease nausea and Vitamin D and B6.


For optimal results, it is recommended that you take 1-2 capsules per hour of activity depending on conditions, terrain, and one’s physiology.  Use in conjunction with Roctane Ultra endurance energy gel for added electrolyte supplementation.  Always hydrate with 24-30 oz. of water per hour during training or racing.


Does vitamin D supplementation help exercise performance?

  • Vitamin D deficiency is common among athletes. In individuals that are vitamin D deficient, supplementation can improve exercise performance.

Why is vitamin B6 in the capsule?

  • Vitamin B6 can help combat that unwanted nausea when athletes push their limits to the max.

Should I take the capsule only during exercise?

  • No!  Roctane Electrolyte Capsule can be taken anytime you feel the need to replenish or prevent electrolyte losses due to exercise.  It can be taken before, during, or after high intensity efforts.

Why is the electrolyte potassium not in the capsule?

  • There is no data to support potassium supplementation during exercise.  Blood potassium concentration does not change or increase during exercise, as potassium is released from muscle contraction.  The increase in potassium during exercise is less dramatic as an athlete becomes more trained, which may help prevent fatigue and has been associated with elevated potassium concentration (potentially due to alterations in membrane depolarization).  Several studies have even shown that potassium ingestion during exercise doesn’t change blood potassium concentration.  For these reasons, potassium is not included in the Roctane Electrolyte Capsule.

How do I incorporate this Roctane electrolyte capsule with other GU products?

  • Some individuals need more electrolytes than others.  The athletes that end each workout looking like a salt stick tend to need more electrolytes than others.  These athletes can supplement the electrolytes that are already in GU Electrolyte Brew, Roctane Ultra Endurance and gels with 1-2 capsules/hour as needed to help replace electrolytes lost in sweat.

    Very impressed with these caps. Have been using them since they came out and have had no issues. In the past other caps have upset my stomach but these are buffered perfectly and keep me from cramping up in the heat and help me continue to train properly
  • The best electrolyte pill out there

    I was given the opportunity to try the new Roctane Caps last summer (2013) while training for and then racing at IM Louisville. For years I had sworn by another caplet product so I was cautious. I tried them in training and really liked the results; found taking one every 45 minutes or so worked great. Kept up that routine an on race day, they were part of my successful NHS plan that included six different GU Energy products - the Capsules, regular gels, Roctane gels, GU Brew, Roctane Brew and finally Recovery Brew. Great products from a great company - Thanks!
