This caffeine product is just the right amount of caffeine! I would drink a monster energy drink when I got home from work to give me the extra energy to take my kids to the park or to play with them at the house. The ZYM is 100 times better. No crash, no random chemicals, and taste great!

This was my second big order. I use two to three tabs a day before, during and after bike rides. I feel like they are helping me power through the workout and recover quicker after the workout. Seems to be working miracles!

This is a terrific product, I love the taste and the vitamin /electrolyte mix is great, but 100mg of caffeine is about 2x what I've typically had in other products and for me it's a little too much.

Sometimes on a short fast ride, I don’t want a sugary drink. Sometimes I want to get out the door early, without the time, for a cup of coffee. The berry + caffeine, stimulates me from the get go. For a fast 90 minutes fasting, this leaves me fresh at the end of the thrash fest.

I started using ZYM recently and absolutely love it. The taste is just strong enough to make it interesting but mild enough to not cause taste fatigue. I also like that the fizz isn’t as intense. I have been using it on all my workouts and have recommended it to the athletes I coach.
