While Kickstart Recharge and Kickstart Hydrating Boost offer mostly the same ingredients, there are some non-trivial differences that show they target fatigue in different ways. To understand these differences in these caffeinated beverages, we need to review the connection between hydration and fatigue, and the relationship between fatigue and vitamins C and E.
But first, a closer look at the ingredients
Kickstart Recharge and Kickstart Hydrating Boost are very similar in terms of ingredients. They both contain 68 milligrams of caffeine per can, which is less than the caffeine in a can of Red Bull. There are more Kickstart flavors available, but let’s focus on two flavors from the Recharge group and two from the Hydrating Boost group. As shown in the table below, all four have the same first three ingredients. After that, the Recharge group differs from the Hydrating Boost group, but the two Hydrating Boost products have identical ingredients lists.
Blood Orange has blood orange juice, Blueberry Pomegranate has blueberry juice, but Watermelon has no watermelon juice, and Strawberry Kiwi has no strawberry juice. Unlike the Recharge group, the Hydrating Boost group has to rely entirely on the added flavors to make it taste like the fruits it’s named after. This seems to explain why the Hydrating Group has both natural and artificial flavors. Natural flavors are usually less potent and less permanent than artificial flavors. Perhaps natural watermelon flavors were not enough in the absence of any watermelon juice.
Hydration and Fatigue – The Hydrating Boost Strategy
Hydrating Boost aims to give you energy by giving you coconut water to fight fatigue from dehydration.
“By the time a person loses 1% to 2% of body weight in fluids, he or she will be thirsty. Even this small water deficit can cause one to feel tired. At 4% loss of body weight, muscles lose significant strength and endurance”
[Straus, L. The Liquid Diet: Role of Water. Introduction to Human Nutrition BILD 22. 2006;8:126].
There’s a reason the solution (pun intended) for Level 1 in my 5 Levels of Fatigue system is water! If you’re tired, you should reach for water before you reach for any caffeine. If you’ve already tried that, perhaps a caffeinated hydration beverage will do?
If you’re doing moderately strenuous activity for at least one hour or high-intensity activity for at least thirty minutes, an electrolyte beverage is preferred to plain water. Ironically, the strongest arguments for electrolyte beverages over water have to do with the fact that electrolyte beverages taste better. Athletes only replace about half the water lost during exercise [Noakes, T. Fluid replacement during exercise. Exerc Sports Sci Rev 1993; 21:297]. Even the American Academy of Pediatrics agrees that the increased fluid intake using flavored electrolyte beverages is probably beneficial [American Academy of Pediatrics. Pediatrics 2000; 106:158-59]. The important thing is you’re drinking more fluids, even if the electrolytes aren’t needed.
Keep in mind Kickstart Hydrating Boost only has 10% juice, and coconut water isn’t even one of the three most prominent ingredients. If you feel Kickstart Hydrating Boost’s coconut water (and caffeine!) gives you energy by keeping you hydrated, I will respect your opinion. Then I will encourage you to drink one glass of water for every can of Kickstart. When the Kickstart can is empty, maybe you should fill it with water and drink it all before you recycle the can.
Vitamins C + E and Fatigue – The Recharge Strategy
Kickstart Recharge aims to give you energy by giving you antioxidants to fight muscle damage. Endurance exercise increases the amount of oxygen we breathe. This increased exposure to oxygen means an increase in free radicals.
“…free radicals can cause damage by joining with other body chemicals and changing their character, sometimes even producing a chain reaction by creating new free radicals that carry on.”
[YouTube video, “Oxygen, Antioxidants, and Free Radicals” watch here]
Free radicals are involved in fatigue and damage to muscle cells. Antioxidants like vitamin E attract these free radicals, slowing down the chain reaction and thus limiting the damage. In the process, vitamin E becomes a radical. Vitamin C can restore vitamin E so it can go back to attracting more free radicals. In turn, vitamin C can be restored by niacin (vitamin B3), which is also included in Kickstart Recharge at 60% of the Daily Value.
Clinical trials providing antioxidants to treat or prevent various diseases have largely been unsuccessful. But don’t discount the Placebo Effect. If you believe that, for you personally, Kickstart Recharge’s antioxidants (and caffeine!) are giving you energy by limiting muscle fatigue and free radical damage, I won’t debate you.
If you haven’t already, read the Energy Drink of the Month review for Kickstart Hydrating Boost. That should help you determine whether or not Kickstart is for you. If it is, you can use the power of science to determine whether you like the Hydrating Boost or Recharge fatigue busting strategy better.
