HEED is a powdered sports drink that contains calories, a full-spectrum electrolyte proﬁle, and key auxiliary nutrients. Endurolytes Fizz is a nearly-calorie-free, full-spectrum electrolyte replenishment product in effervescent tablet form.
Every scoop of HEED contains 110 calories and about the same amounts of electrolytes as one-half tablet of Endurolytes Fizz. While taking into account the many variables that determine how much electrolytic mineral support you need, most athletes find that 2-4 Endurolytes capsules of 1-2 Endurolytes Fizz tablets work extremely well. With that in mind, lighter-weight athletes will oftentimes ﬁnd that 1.0 - 1.25 scoops of HEED in a water bottle (110 - 137.5 calories) will oftentimes cover their entire fueling requirements — ﬂuids, calories, and electrolytes — for an hour. The same is true for most athletes who are doing short-duration workouts and require only minimal amounts of calories and electrolytes. Medium-weight athletes will find that 1.5 scoops of HEED will provide the appropriate amount of calories (165), but that 1-2 capsules of Endurolytes or ½ to 1 tablet of Endurolytes Fizz may be needed to cover electrolyte needs more completely. Heavier-weight athletes will find that 1.75 scoops of HEED (192.5 calories) should be sufficient, though up to 2.0 level scoops (~205 calories) is acceptable. These amounts will also provide 1.75 - 2.0 capsules’ worth of Endurolytes or approximately 1 tablet of Endurolytes Fizz. Additional amounts will be needed, usually in the amounts of 1-2 Endurolytes capsules or 1 tablet of Endurolytes Fizz.
During longer bouts of exercise, when Perpetuem or Sustained Energy is the primary fuel (and especially when concentrated, multi-hour bottles of either product are being used), Endurolytes Fizz is an ideal alternative to Endurolytes capsules, primarily for athletes who are either unable to swallow capsules during exercise, or who prefer to fulﬁll their electrolytic mineral needs via lightly ﬂavored, effervescent (“ﬁzzy”) electrolyte water.
A key point to remember is that if you put “X” amount of scoops of HEED or “X” number of Endurolytes Fizz in your water bottle, your dose is preset . . . you’ve basically put a ceiling on it, which can become an issue if what you’ve put in your bottle is proving to be insufﬁcient (such as if the weather gets hotter). Therefore, we highly recommend that you carry extra Endurolytes Fizz tablets or Endurolytes capsules. You may end up not needing them, but you’ll feel better knowing that you have them within easy reach, should the conditions require more electrolytic mineral support than what you’re obtaining from however many scoops of HEED or Endurolytes Fizz tablets you’ve put in your bottle.
Lastly, you can most deﬁnitely add Endurolytes Fizz tablets to your bottle(s) of HEED to bolster the electrolyte content. If you’re adventurous, you can create a new ﬂavor by, for example, adding Grape Endurolytes Fizz to Melon HEED, or numerous other creative combinations.
Bottom line: HEED = Calories + electrolytes; Endurolytes Fizz = Electrolytes only. Now you know the differences between these two great fuels!
