    The difference in my energy level is profound. I was drinking more water to combat fatigue but without replacing these key electrolytes the exercise was counter productive. I'm really feeling good. Thank you!

  • "More than H2O!"

    Fast Fuel proves you need more that plain-ol-water to keep the ability to sweat and keeping going. I can suffer heart palpitations and I have had absolutely none since i started taking FF. Read the label and see what you get for your money. Thx

    Ideal way to stay hydrated! FF are the best on the market. They taste great and have the highest sodium out of any other hydration supplements, which is perfect for my low carb lifestyle.

  • "I ordered unflavored."

    It is very tasty even though it's unflavored. It feels like it's more fulfilling than just water by itself.

  • "Love this product"

    This is the best hydration product I have tried!! Love that it has no sugar!!!!! All the others have sugar or Splenda. It actually tastes great too - makes the water a little salty!

  • "Just what I was looking for"

    I’ve been looking for a flavorless electrolyte and was having trouble finding it. This has simple ingredients and more of what you need than other electrolyte products. I also appreciate the guide on the package that tells you how to use it depending on whether you are intermittent fasting, extended or on Keto. It has helped me a great deal. I will continue to purchase.

  • "No More Foot Cramps"

    I use one scoop a day with my other supplementation and I no longer have leg and feet cramps at night. I’ve only used it a week, so I need more time to determine if there are any side effects so I can decide if it’s a permanent addition to my diet.

  • "Perfect for my use"

    I love the hassle free way this product makes electrolyte intake during my extended fasts. The flavor is decent and helps with the drinkability of the salts. Will definitely buy again.

  • "Great for a Boost of Energy"

    I ordered this for my wife in hopes that it would give her a boost of energy throughout her day. So far it has been doing quite well and comparable to other like items on market and hydration multipliers used before this. Just a quick note, it is very salty. We added it to a flavored drink and that did the trick.
