Race Rx is different to the vast majority of sports drinks. Race Rx derives it’s power from a patent pending natural plant fuel with some unique characteristics.

  • A Sports Drink Powered by High Density Amylopectin (HDATM ). Race Rx uses a proprietary starch complex derived from the Cassava plant to provide an athlete The best sports drink energy sourcewith sustained, slow release energy during prolonged exercise. Race Rx is designed to maintain your blood sugar level within it’s normal range with none of the detrimental spikes and crashes associated with sports drinks based on sugar and maltodextrin.

    How does it work…Sugars are the smallest and most readily absorbed carbohydrates, made up of just one or at most two sugar molecules stuck together. Next up in terms of size is maltodextrin, typically composed of between 3 and 17 sugar molecules strung together in a short chain. By contrast the Amylopectin that makes up the vast majority of our HDA starch complex is composed of 2 – 4 million sugar molecules strung together in a huge, branched chain. This massive difference in size and complexity is what creates the slow, timed, release of energy into the blood stream with Race Rx.


  • High Relative Solubility in Water. An endurance drink based on starch that tastes good? Most starches dissolve poorly in water, giving them a ‘paste like’ feel in the mouth when you drink them, and a chalky, gritty taste. If you’re already feeling a bit rough half way through a long race the last thing you need to be drinking is something that turns your stomach, even a little can be enough to spell disaster. Race Rx’s unique starch readily dissipates in water and has a neutral taste so it feels and tastes more like water making it much easier to drink.


  • Low Osmotic Potential. The starch in Race Rx is composed of  “osmotically inactive water soluble granules 5 – 40 μm in diameter”. What does that mean for you? Well, osmotically inactive means that the microscopic strach grains don’t pull water in, and that’s important for a sports drink. It means the starch in Race Rx does not pull water into your stomach from your blood stream, instead it sits for just a few minutes in your stomach before being passed through to your small intestine.  Contrast that with a sports drink containing simple carbohydrates like sugar or maltodextrin. Both of these do exert an osmotic pull and will bring water into your stomach from your blood stream. This has the effect of temporarily dehydrating you (bad),  filling your stomach (bad), and contributing to nausea (definitely bad).


  • Zero Simple Sugars. Sports drinks containing simple sugars such as glucose, fructose, dextrose, sucrose, etc., are rapidly absorbed into the blood stream. In effect they get ‘dumped’ into your blood stream in one hit right after you consume them. Having more sugar sounds good, but if you add it all in one shot like that your body will respond by secreting the hormone insulin. Insulin stimulates your body to pull sugar out of the blood stream and store it. The net result is that you experience a brief sugar high as the sugar enters the blood, but within a matter of minutes insulin is working to reduce the sugar level in the blood, 15 or 20 minutes later your blood sugar level will actually dip below the point it was at before you ate all that sugar, this is the crash, caused by your bodys reaction to all that sugar hitting it in one go. Crashing like this causes symptoms of nausea, muscular weakness, a lack of concentration and alertness. Want to avoid the crash? avoid the simple sugar.


  • No Maltodextrin. Moderate complexity carbohydrates are ok in small doses (in fact Race Rx contains a low dose in the form of Amylose, which helps to maintain a healthy blood sugar level as part of our proprietary carbohydrate complex). But you don’t want moderate complexity carbohydrates to form the mainstay of your fueling strategy. Why? because they exert a high osmotic pressure,
    Maltodextrin may not be the best choice for a sports drink
     drawing fluid into the stomach and leaving you feeling bloated. If you’re adrenalin level is high (like it is on race day), your body is channeling blood flow away from your stomach, and things like maltodextrin can end up sitting in your stomach like a rock. That’s why you’ll often see people at the side of the road vomiting (sorry there’s no nice way to put that) part way through the bike leg, sometimes on the run. Chances are pretty good they are getting rid of a stomach full of carbohydrate they couldn’t digest. Unfortunately they also just threw up all the water it sucked out of their blood stream as well, so now they’re dehydrated to boot. Training is tough, race day is tougher. Make sure your fuel clears quickly and easily from the stomach and doesn’t leave you at the side of the road wishing you’d done things differently.
