Input: Yes, it's probably healthier than 5-Hour Energy or Starbucks shots but if you're looking to avoid a caffeine overload, this is still not for you. Most energy drinks cannot be made w/ out a high dosage of caffeine. I believe the caffeine content of 1 Guayaki shot is 150 mL - probably lower than other un-healthy energy shot drinks but I believe most other people avoid the top brands b/c they contain too much caffeine and/or sugar. If you do not react well to caffeine, Guayaki is not a good buy either. I definitely feel an energy boost w/ 1 full Guayaki shot but not w/ out all the other caffeine side effects - irritability, nervousness, mood-swings. Caffeine overdose is why I stopped drinking coffee. But it looks even organic energy drinks are still not safe. Now you're NOT sensitive to caffeine, then it's a great buy. It's not loaded w/ sugar. The taste is easy and pleasant. It's not loaded w/ a bunch of chemicals like 5-Hour shots or Starbucks drinks. And the energy boost lasts for about 4 to 5 hours. Takes about 5 to 7 minutes to kick in but all this probably depends on your body/weight. Side note - if you want to feel energized during the day, have a protein drink first thing in the morning and stay away for heavy, fattening foods during the day that will make you feel sluggish and sleepy!
