Multiple gold medal winning Michael Phelps drinks it. PureSport is the latest energy drink and is the result of being developed at the University of Texas by Dr. John Ivy, to “nutritionally enhance the human body’s performance during and after strenuous athletic activity."

So if it’s good enough for Phelps, it must surely be good enough for us humble riders. Dr. John Ivy actually created the drink specifically for the University of Texas men's swim team for them to use instead of other readily available energy drinks, and he seems to have found the right balance of ingredients, if eight gold medals is anything to go by.

So what are the products and what’s in them? PureSport is a sports drinks with protein featuring whey protein isolate, antioxidants, electrolytes and natural sugars, and available in Workout and Recovery versions.

Recovery uses a precise carbohydrate-to-protein ratio of 2:67-to-1 mixture and so accelerates the replacement and storage of muscle fuel, with the added protein reducing muscle damage and inducing muscle repair. Taken within 15 minutes after exercising to “help your body get into the recovery zone quickly and bounce back after serious physical activity." $24.99 gets you 10 PureSport Recovery packets which provides 10 servings. Available in all four flavors: Grape, Banana Berry, Lemon Lime and Fruit Punch.

PureSport Workout replaces lost fluids and electrolytes, restores fuel during exercise for more energy and improved performance, and enhances recovery with added protein. A combination of dextrose and fructose promotes a faster rate of carbohydrate uptake into the circulation from the intestines. Also present beside the essential carbohydrates are protein/amino acids and electrolytes.
