Human Sweat Based Isotonic Mix

Nrgy Unit Drink has an optimal carbohydrate composition (1:0.8 ratio of maltodextrin and fructose) according to scientific research. This ratio has been proposed by a group of researchers led by the renowned scientist David Rowlands from New Zealand, who discovered this ratio leads to the most efficient replenishment of both muscle and liver glycogen stores.

Following the scientific explorations of modern nutritionists, our sports drinks contain electrolytes in identical concentrations of human sweat, which allows you to replace only the electrolytes you actually lose during exercise. This stimulates efficient rehydration without causing digestive issues or negatively impacting muscle function.

Our products use Nrgy Units, a system designed to simplify fueling during exercise. Our sports drinks and energy gels are all based on the Nrgy Unit System and contain the same ratio of maltodextrin and fructose. This allows you to freely mix and match them according to circumstances and personal preference.

We put a lot of effort into creating products that our customers can truly enjoy. Our third-generation sports drink is distinguished by a uniquely fresh and tantalizing taste with new flavors and, due to popular demand, a brand new citric acid flavor line!


  • Optimal replenishment of muscle and liver glycogen stores
  • Allows consumption of 90 to 120 grams of carbohydrates per hour
  • Efficient in preventing muscle cramps
  • Electrolytes in identical ratio to human sweat for optimized rehydration
  • Increase energy levels and decrease fatigue
  • Free from harmful additives, flavors, colors, and artificial sweeteners
  • Suitable for children and vegans

  • Maltodextrin, fructose, electrolytes (sodium chloride, potassium tricitrate, calcium tricitrate, magnesium tricitrate), natural aroma. No known allergens.

    Simplified dosing allows you to focus on your physical activity:

    One energy unit per hour = one scoop (basic or short workouts up to two hours) in 500 ml of water. 

    Two energy units per hour = two scoops, one for each of the two separate 500 ml bottles (exercise over two hours or extremely intense workouts and races). In hot conditions, the bottle should contain 750 ml of water.

    Our philosophy is simple - provide athletes with products that are scientifically proven to be effective. The task we presented ourselves with was to introduce to the market a drink that is based on strong scientific evidence, as we strongly stand behind our slogan: "Fueled by research".

    Nrgy Unit Drink contains a mixture of a glucose-based carbohydrate source (maltodextrin) and fructose, but the adopted 1:0.8 ratio is a deviation from the common 2:1 ratio. A ratio closer to equality has been shown to be more effective in regard to performance, glycogen sparing, and comfort of the gastrointestinal system.

    The electrolyte content of Nrgy Unit Drink is in line with the average content of human sweat so that you replace what you lost.

    A recently published study found that in elite runners ingestion of large amounts of carbohydrates (120 grams per hour) resulted in a significant reduction in markers of muscle damage in the post-run period: ↪️ https://pubmed.ncbi.nlm.nih.gov/32403259/.

    The question of what a sports drink should contain is very complex. Most manufacturers simply take formulations from their competitors and tweak them only so that they can say they are different.

    We took a different approach. 

    Our experts reviewed the available literature and based the final formulation of the product based on solid evidence. In this article Baker and Jeukendrup discuss the "optimal composition" of fluid-replacement beverages: ↪️ https://pubmed.ncbi.nlm.nih.gov/24715561/

    It is a rarity to find fructose in sports nutrition products. But when it is there, manufacturers usually choose a 2:1 maltodextrin to fructose ratio. However, a closer look at the literature reveals that the optimal ratio is actually 1:0.8. In this paper, David Rowlands and his colleagues present this issue: ↪️ https://pubmed.ncbi.nlm.nih.gov/26373645/

    The Nrgy Unit Drink was developed with three main aims in mind:

    • the carbohydrate content should be optimal both from the composition as well as quantity standpoint;
    • the electrolytes should be in a ratio that allows them to enter the cell;
    • it should contain nothing more than the things the body actually needs during exercise.

    The latter applies especially to some electrolytes and minerals. For instance, magnesium is not lost in substantial amounts during exercise and can even cause gastrointestinal problems if present in large quantities, as it makes the drink hypertonic. On the other hand, replacing other electrolytes, especially sodium, is important to maintain normal electrolyte concentrations in the bloodstream.


    During intense activity, we can deplete carbohydrate stores (i.e., glycogen) extremely quickly, sometimes at a rate higher than three grams per minute. We can deplete glycogen stores in as soon as 90 minutes. When this occurs, performance starts to substantially decline. We feel that as a sensation of extreme fatigue and heavy legs. Sometimes, it can even occur that we “hit the wall” or “bonk”. This is when blood glucose concentrations drop below normal values and the brain does not have the energy it requires. By regularly adding adequate amounts of carbohydrates, glycogen is depleted more slowly, thus limiting the decline in performance. In addition to this, a lack of carbohydrate supply encourages the body to break down protein.

    Many carbohydrate-based drinks target only one carbohydrate type - glucose. It is currently believed that the limitation of the utilization of ingested carbohydrates lies in the intestinal transport of carbohydrates. Glucose uses the transporter SLGT1, whereas fructose (another monosaccharide) uses a different transporter (GLUT5). Thus, by having two types of carbohydrates, namely maltodextrin and fructose, we can utilize two transporters and achieve higher carbohydrate absorption rates.


    Nrgy Unit Drink contains an optimal ratio of maltodextrin (considered the most gentle to the stomach) and fructose. A ratio of 1:0.8 is ideal because it allows us to absorb between 90 and 120 grams of carbohydrates per hour, which is 50-100% more than your ordinary beverage.

    The sports drink Nrgy Unit Drink takes into account both key receptors, the glucose receptor (SLGT1 and GLUT2) and the additional fructose receptor (GLUT5), and therefore allows us to ingest up to 120 grams of carbohydrates per hour during exercise instead of the usual 60 grams, which was the amount anecdotally determined to be the upper limit (in practice, this number is closer to 40-50 grams)


    We have mentioned that most sports drinks contain carbohydrates that target only the glucose transporter. This means that we can consume and utilize 50 or maybe 60 grams of carbohydrates per hour, which is not enough to reduce reliance on liver and muscle glycogen. If we consume more sports drinks or energy gels, we also get more carbohydrates in the digestive tract, but because the limiting factor is the transport from the intestine into the bloodstream, intakes higher than 60 grams per hour will result in carbohydrates being left unabsorbed in the intestines.

    The highly-concentrated mixture of electrolytes, minerals, and glucose then piles in the small intestine, creating a highly hypertonic environment compared to the blood. This causes water to pass the intestinal wall in the wrong direction (from the blood into the intestine) leading to diarrhea and other gastrointestinal problems.

    Ingestion of an optimal amount and composition of carbohydrates is the most effective way to prevent gastrointestinal issues.


    One of the most interesting misconceptions in sports physiology is the myth of electrolytes. It is widely believed that electrolytes either prevent muscle cramping or that cramps are caused by magnesium lost during exercise. The truth is that during exercise without replacing the fluids, the concentration of electrolytes in the body actually increases. This means their availability is increased rather than decreased. There is thus no way for loss of electrolytes or minerals to be a primary cause of muscle cramps. The problem can occur if we do not replace electrolytes and minerals lost in the sweat and only drink water. Nrgy Unit Drink consists of the same amount of electrolytes and minerals lost in the sweat, allowing you to replace what you are losing.

    Magnesium is an essential mineral that has to be consumed as part of a healthy diet. This is considered common sense. However, there is a prevailing misconception that magnesium supplementation during exercise reduces the occurrence of muscle cramps. There is no evidence whatsoever that magnesium supplementation during exercise actually prevents muscle cramping. This makes sense if we consider that the only way magnesium can be lost is by sweating. And there is barely any magnesium in the sweat. Interestingly, adding magnesium into a beverage drunk during exercise can lead to gastrointestinal problems. The reason for this is that magnesium increases the tonicity of the solution making it more hypertonic.

    The electrolytes we are losing in the sweat in the highest concentrations are actually sodium, chloride, potassium, and calcium. And this is what we need to replace during exercise.

    But if it is not the electrolyte imbalance, what is then the main cause of muscle cramps?

    The mechanisms for the formation of muscle cramps are presently not completely understood. However, it seems they originate in the central nervous system, as we can relax them by stretching. They probably occur as a result of fatigue and over-exertion.

    As we all know, fatigue in endurance types of events is often a result of depletion of carbohydrate stores. By consuming enough carbohydrates, you can also reduce the occurrence of muscle cramps.

    Here, the optimal ratio and types of carbohydrates are crucial - an additional 30 grams of carbohydrates will have a decisive effect on whether a muscle cramp at your top performance will occur or not.
