Test GoldNutrition Carb Max Gel

Carb Max by GoldNutrition: a gel born in Portugal, testrigorously, and validated for a high-level objective

In the world of endurance, there was a time when only the ability to "take it" mattered: the kilometers, the elevation changes, the suffering. Today, performance has become a matter of precision. Of mastered details. And among these details, nutrition occupies a central place. To drink or not to drink, to refuel or not—these are questions that the elite no longer hesitate to answer. Because science has spoken. And it says clearly: at high intensity, for durations exceeding one hour, energy must be provided continuously. This principle is now embodied by a reference protocol: the absorption of 80 to 90 g of carbohydrates per hour of racing. A performance standard now adopted in major marathons, trail running, Ironman, but also in half-marathons contested at maximum intensity. But you still need to find the right product, the right dosage, and above all, the assurance that it will pass the effort. This is what a test rigorous testing was carried out with GoldNutrition Carb Max gel.

A serious, structured approach... and 100% field-based

The project is simple: to evaluate the real effectiveness of an energy gel sold as efficient, practical and well tolerated.. And not in a laboratory. But in the legs. For this, we asked Tiago Tatard, a young 18-year-old French runner, 10th in the ranking national half-marathon in his category, and currently in full preparation for the French Half-Marathon Championships in Vannes, on September 14.

But here, Tiago is above all a testAn athlete, certainly, but also a first-year student at Audencia, a renowned business school. And this dual role is reflected in his method: organization, rigor, strategy. test was therefore not done lightly: it was thought out, structured, and integrated into a coherent preparation protocol.

For our test product, this time it is a young athlete and business school student, who will put the Gold Nutrition gel to the test... not in the laboratory, but on the asphalt.

The science behind it: why aim for 80g/h of carbohydrates?

For a long time, recommendations for endurance sports were around 30 to 60 g of carbohydrates per hour. But research conducted over the last fifteen years—particularly by Jeukendrup, Burke, and Stelli—has shown that the intake of carbohydrates in endurance sports is often higher than that of other sports.ngwerff — showed that by combining two types of sugars (glucose + fructose), it was possible to significantly increase the absorption capacity intestfinal, and therefore push back fatigue.

The key: using different transporters (SGLT1 for glucose, GLUT5 for fructose), respecting an optimal 2:1 ratio, to achieve up to 90–100 g/h of carbohydrates without digestive discomfort. But to get there, you have to train yourself to digest. And you need a suitable product. The product testé: Carb Max Energy Gel 60g – GoldNutrition

Carb Max Energy Gel, in its 16-pack format: 40g of net carbohydrates per unit, a performance concentrate born in Portugal. GoldNutrition's Carb Max Gel seems to meet all these requirements. Here are its key points:

40g of carbohydrates per gel
Optimized glucose/fructose ratio
Fluid texture, absorbable without water if necessary
Well-tolerated neutral flavor
Zero unnecessary additives
Certified doping-free
Produced in Portugal, testin an independent laboratory

Each gel weighs 60g, but contains 40g of net carbs, a great yieldThis is exactly the target amount every 30 minutes to reach the famous 80 g/h.

Test terrain: a demanding protocol, faithful to the reality of the race

In order not to be satisfied with simple impressions or a test punctual, the protocol put in place by Tiago was designed with a logic of real physiological adaptation, with variables modeled on the exact conditions of race day.

For several weeks, the Carb Max gel was systematically integrated into all of the so-called " high glycogen ", that is to say the key sessions of his preparation, where the energy intake directly conditions the quality of the training and the capacity to repeat it over time.

Tiago in action: taking the gel followed by controlled hydration — a precise routine, repeated at each key session.

The protocol was structured around the following elements:

Realistic outdoor temperatures, between 22°C and 30°C, to simulate the heat expected in September in Vannes. This data is essential, because the heat increases digestive risks - no adverse effects have been noted, however.
Duration of effort between 1 hour and 1 hour 30 minutes, corresponding exactly to the effort time targeted on the day of the championship.
Calibrated intensity “half-marathon”, that is to say at the threshold, with a high heart rate, where digestion is often compromised.
Take the gel with water only, without sugary drinks or caffeine, to isolate the effect of the gel itself.
Repeated application, with one dose every 30 minutes, in the same way as what will be done on D-day, in order to also train the digestive system to receive a high glycemic load.

What Tiago has put in place is not a simple test “taste”, but rather a progressive nutritional training, as recommended by the latest scientific research. The objective: to accustom the gastrointestinal systemtestfinal to digest 80 g/h of carbohydrates, while remaining in a logic of maximum performance during exercise.

60 minutes of effort, always high intensity: here, the second dose of the gel, essential to maintain the pace until the end.

« You don't improvise a supply strategy at this level. It had to be testproven, and above all integrated into my pre-race routines. »

Tiago therefore took a gel before each long session, then every 30 minutes, even on threshold sessions or long VMA blocks, in order to reproduce the mechanical demands of racing. He thus “trained his intestin”, according to the recommendations of specialists such as Asker Jeukendrup.

And the results are clear:

Zero digestive discomfort
No acid reflux
No feeling of heaviness
No sudden variation in perceived energy
Sensation of stable absorption, without “peak” or “crash”

In short: the product has passed the field test with flying colors. So much so that it has been chosen as the official race day nutritional solution. It is no longer a test, it is a validation.

The nutritional plan for D-day is now finalized

On September 14, at the French Championships, Tiago will take no risks. The protocol validated in training will be reproduced identically, with 3 Carb Max gels embedded in the pockets of his shorts:

1st frost → just before departure
2nd gel → at the 30th minute of the race
3rd gel → at the 60th minute

This plan guarantees a constant intake of 80 g/h, perfectly assimilated, to maintain a high level of intensity until the finish.

The GoldNutrition logic: quality, simplicity, performance

GoldNutrition is a brand founded in Portugal, whose philosophy is simple: to formulate clear, effective products, testés, without superfluity.

Little known in France, it is gaining ground thanks to:

Its transparency on the compositions
Its very competitive price/quality ratio
Its anti-doping commitment (products test(in an approved laboratory)
And a consistent range: proteins, gels, sports drinks, recovery drinks, etc.

Carb Max is part of this logic. No flashy marketing, but a product that works, period.

Le testeur, Tiago Tatard: between academic rigor and sporting demands

This nutritional choice is not just an athlete's fad.. It also reflects a rational, almost entrepreneurial approach. Tiago is a young rider with great potential — but also a brilliant student at Audencia, who builds his decisions like one builds a business plan: by tests, validations, adjustments.

And in this logic, the Portuguese gel has become more than a fuel. It is a strategic choice, made consciously, after weeks of analysis.

Message 3bikes.fr Never throw a gel into the environment: performance is no excuse for disrespect. Responsible athletes, responsible actions.

When nutrition becomes a weapon

Ce test is not a publicity stunt. It is the story of an intelligent approach, led by a young athlete who makes his decisions with the same rigor he puts into his training.

GoldNutrition's Carb Max, a discreet but incredibly effective Portuguese product, is now at the heart of his race strategy. Because on championship day, every minute will count. And to reach the podium, every detail counts too.
