Built for active use, this formula focuses on helping maintain fluid balance and plasma volume with a concentrated blend that fits neatly into a performance hydration plan. Each bottle contains 50 capsules, so it is easy to keep a reliable supply in a vest, pocket, or race bag without adding bulk. For runners who want a lightweight option, the capsules offer a practical way to keep nutrition streamlined.

Why Roctane Electolyte Capsules Fit Hot Runs
The appeal of Roctane Electolyte Capsules is their no-fuss approach. Instead of mixing a bottle or carrying extra liquid, the capsules give runners a lightweight option for targeted electrolyte replenishment while staying focused on the effort ahead.
Take 1 to 2 capsules per hour during high-intensity activity, and swallow with at least 3 to 4 oz of water as part of a broader hydration strategy. For longer outings, pairing them with regular fluid intake helps keep the system moving smoothly.
- Efficient support for hot-weather training and race-day conditions.
- Compact and convenient for minimalist hydration setups.
- Useful during sustained effort when sweat losses are higher.
- Easy to slot into an existing plan alongside drink mix, gels, or food.

WHAT WOULD WARRANT THE NEED FOR THIS PRODUCT? WHY WAS IT CREATED?
Created to supplement additional electrolyte replacement needs, GU ROCTANE Electrolyte Capsules provide added electrolyte support on top of our hydration-drink products. Each bottle includes 50 capsules that are packed with electrolytes (sodium, magnesium, chloride) to aid in hydration by maintaining water balance and plasma volume. Vitamin D is important for calcium absorption and bone health. Take GU ROCTANE Electrolyte Capsules before, during, or after exercise to replenish electrolyte levels from any energy-demanding activity resulting in sweat loss. If you’re pushing yourself in hot or humid conditions, it’s easy to become dehydrated. When you’re dehydrated, your performance suffers, you become fatigued faster, and you can get cramps or headaches.
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 gels with 1-2 capsules/hour as needed to help replace electrolytes lost in sweat. ROCTANE Electrolyte Capsules help replace what you lose when you sweat to keep you feeling strong and feeling good. Take 1-2 capsules per hour during high-intensity activity and consume with at least 3-4 oz of water.
