This last summer I got interested in electrolyte drink tablets for mountain biking, as they provide athletic enhancement, and are the perfect product to add to a hydration reservoir or water bottle, without the fuss of powder. I stumbled upon ZYM’s booth at the massive 2010 Interbike show, and was intrigued by their new product named Rival, that uses the natural Stevia sweetener. I found all their products were pleasant tasting, with a very mild sweetness.
The precise maintenance of electrolytes levels is important, as they affect and regulate the hydration of the body as well as blood pH, and are critical for nerve and muscle function. Without sufficient levels of key electrolytes, muscle weakness, severe muscle contraction, and fatigue can occur. ZYM tablets contain a special blend of electrolytes, vitamins and minerals to help maintain body fluid balance, for optimal athletic performance and normal metabolic functioning. Your body requires water, and during vigorous exercise you lose water through perspiration, along with vital minerals and electrolytes. You can re-hydrate faster and more efficiently drinking an electrolyte rich water.
These self-dissolving effervescent tablets are suited for the mountain bike set, since one tablet can be added to 16 -20 oz of water, which works nicely for a hydration reservoir, or a water bottle. ZYM comes in a plastic tube that contains 10 tablets, costs $8-10, and comes in three versions, each with their own flavor, Rival (orange), Endurance (lemon-lime), and Catapult (berry). The ZYM versions each has different ingredients, but they are either sugar free or low in sugar, so you don’t get the usual sugar boost from most sport drinks followed by the inevitable bonk. The lack of sugar also means no sticky residue in your water bottle or reservoir, so cleanup is easy. A sugar substitute is a food additive that duplicates the effect of sugar in taste, usually with less food energy, and are either naturally occurring (Stevia, Sorbitol and Xylitol), or synthetically made (Aspartame, Sucralose, Neotame, Acesulfame Potassium, and Saccharin). You can find a plethora of information on the internet on the health controversy on the latter substances, but in moderation they can have their place. Better fitness through science! ZYM uses natural flavors, colors and sweeteners (Rival), and is Gluten free and Vegan friendly (makes PETA happy?).
