One of the key features of our new product Plus for Nuun is its unique blend of performance based carbohydrates and optimal electrolytes. The carbohydrates in Plus serve many roles, both in hydration and fueling. Before we get into the nitty gritty details of the carbohydrate (CHO) sources in Plus, lets first look at carbohydrates and their effects on exercise performance in general.

Carbohydrates play key roles in sports performance, specifically for hydration and fueling with several studies proving this theory over the years (1,2). Carbohydrates can help fuel your muscles and enhance the delivery of fluids and nutrients (5). It is widely known that when exercising at a higher intensity and/or longer durations, your body will start using other (stored) fuel sources (carbohydrates) to help maintain performance. When the body beings to deplete its stored muscle and liver glycogen – fatigue (or bonking) can set in. That is where carbohydrates via fluids and external food sources (bars, gels, chews) come in hand. They can provide your body with the calories it needs, as well as, increase the rate of nutrient delivery (5,18).

Carbohydrates for hydration

In hydration, carbohydrates play key roles in fluid and nutrient delivery and absorption (5). The concentration and make up of the solution you’re consuming can play a vital role in how your body will oxidize (utilize) the carbohydrates and electrolytes you are consuming (7). Plus is a flavorless tablet that contains a blend of performance based carbohydrates + electrolytes. The product is formulated to help increase gastric emptying (rate of nutrient delivery) by its hypotonic (<6% CHO concentration) solution characterization (7,8,9).

Products that are overly concentrated with carbohydrates often utilize only a singular absorption pathway, leaving residual carbohydrates floating within your plasma. This has been known to cause gastrointestinal issues (GI) and stomach issues (7,10). When you consume overly concentrated sports drinks, you are essentially creating waste. With the high(er) amount of CHO’s your body can get overwhelmed by what its given at that moment – that’s when bloating and sloshing of fluids come into play – what’s causing that is the high carbohydrate concentration.

Carbohydrates for fueling

In fueling, carbohydrates also play important roles. As mentioned earlier, when exercising at a higher intensity the body will begin relying on carbohydrates more for fuel (and some fat) (1,2). Therefore, your body will depend on your glycogen (stored form of carbohydrates) stores for fuel. Stored glycogen is primarily located within liver and muscle tissue. When you give your body the nutrients (carbohydrates) it needs at those higher intensities, you spare glycogen. Those CHO’s you’re taking in will help keep your blood sugar constant, and help maximize exercise performance (17,18,20).

Carbohydrates in plus

Plus uses multiple carbohydrates sources (non-GMO d-glucose and organic sucrose) to help the athlete utilize several absorption pathways, helping increase the efficiency of what you are consuming (5,6,7). Consuming multiple sources of carbohydrates will also help your body oxidize more carbohydrates resulting in faster more effective hydration (6,7). Consuming these additional sources of carbohydrates will also decrease the onset of fatigue, and gastrointestinal issues (GI) (5).

Each tablet of Plus contains 5g of carbohydrates, with 125 mg of additional electrolytes. Combine 2-4 tablets of plus with your favorite flavor of Active or Energy to fuel faster! And remember, Plus is in the same form factor as our other products – utilizing effervescent technology for increased absorption (24,25,26).
