F3 Energy offers invigorating energy drinks with nootropic benefits to keep you fueled and focused throughout your day. The “mood” drinks are relaxing naturally - easing anxiety and helping us end the day without alcohol, carbs or calories and tasting great too! Because of the natural ingredients I feel good sharing them with others too. I'm so glad that I tried these. I will continue to buy. No jitters or crashes after drinking and it didn't upset my belly. The citrus tasted similar to Ginger Ale to me. Very refreshing and exactly what I need after a long workout.
