Sale price Price €14,99 Regular price €24,95 Unit price  per 

Tax included.

WHAT IS NEW HERE?
  • 90g of CHO per hour easily. And all the way to the 120 g/h.
  • GI discomfort? Thanks, but no thanks.
  • Tasty, but without NO-GOs.
  • Compatibility with NDURE High Energy Gel - 1 for 1.

We pride ourselves to develop the first isotonic energy-hydration drink with an optimal carbohydrate composition (1:0.8 - maltodextrin:fructose) that is without artificial sweeteners and at the same time contains electrolytes in identical concentrations of the lost sweat. The 1:0.8 maltodextrin:fructose ratio is not new.

It has been proposed by a group of researchers led by a well renowned scientist David Rowlands from New Zealand. Unfortunately, this proposition that has strong scientific evidence has not been adopted by other manufacturers likely due to not being up-to-date with the literature We are also introducing NRGY units, a revolutionary way on how to simplify fuelling during exercise.

All our products contain the same maltodextrin:fructose ratio and if taken in accordance with the guidelines, you get the same amount of energy from each of the products. You simply choose which one you like in a given moment. Ndure is currently available as a prototype in a 900g bag, as Nduranz wants additional feedback on flavours - there has been a link between flavour and subjective perception of exertion, with the company offering the product at a single 40% lower price to develop the most pleasing flavours without artificial additives.

    Maltodextrin, fructose, electrolytes (sodium chloride, potassium citrate, calcium citrate, magnesium citrate), natural aroma.

    No known allergens.


    Dosing is simplified so that you don't have to think of other than race:

    1 energy unit per hour = 2 scoops (basic or short workouts up to 2h) in 500ml of water.

    2 energy units per hour = 2 scoops, one for each of the 2 separate 500ml bottles (workouts over 2 hours or less, extremely intense workouts and races). In hot conditions, the bottle should contain 750ml of water.

    For more details check the Fuelling guide.

    Our philosophy is simple - provide athletes with the products that are scientifically proven to be effective. So - not only does NDURE contain a mixture of glucose based carbohydrate source (i.e., maltodextrin) and fructose, but the adopted ratio 1:0.8 is a deviation from a common 2:1 ratio. Ratio closer to unity has been shown to be more effective not only from the perspective from performance, but also glycogen sparing and gut comfort.

    The electrolyte content of the Ndure is in line with average content of human sweat so that you replace what you lost. It is as simple as that. 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: "Fuelled by research".

    Here you can find some articles that we found interesting when designing this product.

    A recently published study found that in elite runners ingestion of large amounts of carbohydrates (i.e., 120 g/h) resulted in a significant reduction in markers of muscle damage in the post-run period. ↪️ https://pubmed.ncbi.nlm.nih.gov/32403259/ The question on what a sports drink should contain is very complex. Most manufacturers simply take formulations from their competitors and tweak it only so that they can say it is 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 beverage. ↪️ 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 decide for a 2:1 (maltodextrin: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 colleagues present this issue: ↪️ https://pubmed.ncbi.nlm.nih.gov/26373645/

    What is new here?

    Ndure was developed with three main aims in mind: a) 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, and c) it should contain nothing more than the things the body actually needs during exercise. The latter applies especially for 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 in the drink 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.


    1. IMPROVING ENERGY AVAILABILITY

    During intense activity, we can use carbohydrate stores (i.e., glycogen) extremely quickly sometimes at a rate higher than 3 grams per minute even 3g per minute. We can deplete glycogen stores in as short as in an hour and a half. 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, lack of carbohydrate supply encourages the body to break down protein.

    The first drawback of most drinks in the market and addressed by Ndure were the ingredients. Many carbohydrate based drinks target only one carbohydrate type - glucose. It is currently believed that limitation of utilisation of ingested carbohydrates lies on the intestinal transport of carbohydrates. Glucose uses transporter SLGT1 whereas fructose (another monosaccharide) uses a different transporter  (GLUT5). Thus, by having two types of carbohydrates, namely maltodextrin and fructose, we can utilise two transporters and by doing this we can achieve a higher absorption rates of carbohydrates.

      

    Ndure contains an optimal ratio of maltodextrin (considered the most gentle to the stomach) and fructose. A ratio of 1:0.8 is ideal, as it allows us to absorb between 90-120g OH/h, which is 50-100% more than with your ordinary beverage. The Ndure isotonic drink takes into account both key receptors, both glucose (SLGT1 and GLUT2) and additional fructose (GLUT5), and therefore allows us to ingest up to 120g of carbohydrates per hour during exercise instead of the usual 60g, which was the amount anecdotally applied to the upper limit (in practice, this number is closer to 40-50g)


    2. REDUCING THE STOMACH DISCOMFORT INCIDENCE

    We have mentioned that most energy and hydration drinks contain carbohydrates that target only the glucose transporter. This means that we can consume and utilise 50g or maybe 60g of carbohydrates per hour, which is not enough to reduce a reliance of liver and muscle glycogen. If we consume more drink or 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 g/h will simply result in carbohydrates being left unabsorbed in the intestines.

    Highly concentrated mixture of electrolytes, minerals and glucose then piles in the small intestine creating a highly hypertonic environment as compared to the blood. This then in turn causes water to pass the intestinal wall in the other wrong direction (i.e., from the blood into the intestine). As this happens, you get diarrhea and other gastrointestinal problems.

    Ingestion of the optimal amounts of carbohydrates in the optimal composition is the most effective way to prevent any gastrointestinal issues and finish the race with the shortest possible racing time.


    3. LOWERING THE MUSCLE CRAMPS INCIDENCE (NOT RELYING ON MAGNESIUM)

    One of the most interesting misconceptions in sport 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 thing is that during exercise without replacing the fluids (i.e., by dehydration), concentration of electrolytes in the body actually increases. So 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 we do not replace electrolytes and minerals lost in the sweat and only drink water. Ndure consists of the same amount of electrolytes and minerals as they are lost in the sweat. So that you are replacing what you are losing.

    Magnesium is an essential mineral that has to be consumed as part of a healthy diet. This is considered as common sense. However, there is a prevailing misconception that Magnesium supplementation during exercise reduces 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 with 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 sweat in the highest concentrations are actually Sodium, Chloride, Potassium and Calcium) And this is what we need to replace during exercise. But if not the electrolyte imbalance,. what is then the main cause of muscle cramps?

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

    As we all know, fatigue in endurance type of events is often a result of depletion of carbohydrate stores. By consuming enough carbohydrates you can also reduce occurrence of muscle cramps. Here, the optimal ratio and types of carbohydrates are crucial - and additional 30 grams of CHO will have a decisive effect on whether the muscle cramp at your top performance will occur or not.


    4. QUALITY CONTROL - NOT ALL THE INGREDIENTS ARE EQUAL

    The quality of the ingredients and the absence of artificial flavours, sweeteners, citric acid, dyes - this is a constant in isotonics - is something that also contributes to both health and well-being. During exercise, the mucous membrane of our gastrointestinal tract is sensitive and, as a result, a high amount  of artificials  (as well as of magnesium our guts cannot handle) can cause discomfort, causing us to either give up or to lose our focus on the training or race. Even a strong flavour enhancer, which we normally enjoy in our free time, can trigger digestive problems.

    To conclude: not every maltodextrin is the same, not every fructose is the same - the method of processing and the final degree of deviation from the sample model is what comes to the fore in the conditions of strenuous exercise.
