What we think

Having trouble meeting your electrolyte or hydration needs through sports drinks alone? Getting tired of the sports drink flavors? Need some extra electrolytes without added calories or carbohydrates? GU has you covered with these electrolyte capsules. Each capsule contains essential electrolytes (sodium, magnesium, chloride) to help maintain fluid balance and plasma volume during long, intense exercise.

These are great for extra hydration support when you’re exercising in hot, humid conditions or for when you’re at risk of losing more than 3% of your body weight in sweat. GU Roctane Electrolyte Capsules restore your electrolytes, help delay mental and physical fatigue, and contain ginger root to minimize stomach upset during training or competition. With added vitamin D to help maintain bone health and vitamin B6 to help reduce symptoms of stress, these capsules can provide more than just hydration support. They are also informed choice certified, so you exactly know what you’re getting with these supplements.


How We Use It

Take 1-2 capsules per hour during high intensity exercise, especially when it will last longer than 2 hours or the weather conditions are extreme. Be sure to consume at least 3-4 oz. of water per capsule to ensure proper hydration and nutrient delivery.

Great pre-workout supplement for cramping!

Kimberly R.

My new found secret weapon for long, hard endurance bike rides! It def works, my secret to no more leg cramps! Couldn’t have done California/Nevada Death Ride Challenge without this!

Janet N.

I use it for long runs and it works great.

Alice O.

This product has worked well for me. After years of cramping at night, I am sleeping through.

Merlin T.

It works perfectly! No more debilitating headaches after running that can last into the next day.


I take 2 of these for runs longer than 4 miles in the summer and fall. My hands used to swell when I would run, but they haven’t since I started taking these capsules. On runs longer than 10 miles, I take 2 before my run and then usually 2 more halfway.

I am a road cyclist. I live in Georgia where summers are brutally hot and humid. I usually ride about 30 miles and I take one before the ride. I have seen a big decrease in cramps and other symptoms of electrolyte loss.
