Nuun vs. GU Brew Electrolyte Tablets

Being a long time user of Cytomax® Performance Drink, I decided to experiment with electrolyte tablets.  I wanted to train my body to burn fat more efficiently by cutting back on Calories consumed during 1-2 hour training rides while maintaining optimal on-bike hydration.  Water along, I found, was not sufficient.  A few times during training, my calves were having muscle cramp.

Both Nuun and GU Brew received good review and were available from Performance Bicycle.  I gave both a try for 3 weeks and had good result and no muscle cramp.

I prefer Nuun.  It tastes better, and unlike GU Brew, it doesn’t leave a salty aftertaste – which I found surprising after comparing the nutritional facts of the two.  Nuun has a higher amount of salt/electrolyte per serving.
