I take this around 9am to help me finish my 16 hour fast (7pm to 11am). Works great!

This makes fasting easy. The small amount of caffeine is great, I don't get jittery. And the electrolytes are great, too! 5 stars!

I like taking them like pixy sticks, but have also tried mixing it with water and it’s delicious! Perfect for taking before a workout or chasing your toddler around all day.

I use this in replacement of my pre-workout, so that I don't overload on caffeine and get jittery. It gives me the energy to do my morning workout without crashing.

I had to drive over 3 hours with my 17-month-old early in the morning and I really didn’t want to have to stop to use the restroom. VivaStix to the rescue! I brought a couple stix in the car and ate them like pixie sticks!

I love how convenient these are. 50mg caffeine a little less than cup of coffee. They don’t make me feel jittery. I like them better than typical sugary energy drinks. The resealable tubes are easier than the tear packets.

To me, it tastes like candy, with a little bit of tartness at the end. Bonus is no sugar so it doesn’t make my teeth feel weird. I felt like I could have a couple without feeling completely wired.

A refreshing drink that is healthier than my usual soft drinks. And I can throw some in my purse or gym bag.

I mix mine with sparkling water. Healthier than a soft drink!
