Why athletes choose Exolactate Gel®
With ExoLactate® Gel, every formulation decision is supported by the scientific and innovation approach. Created through rigorous scientific process, it is the result of three years of cautious, precise development to achieve the best performing product for the human body.
How to use
ExoLactate® Gel is a lactate gel for all sports disciplines where energy demands are increased, short or long duration. Cycling, trail and road running, triathlon, swimming, football, etc.
Lactate is much more than a preferred energy source. While giving energy, lactate signals beneficial physiological processes for performance. Lactate can make substrate utilisation more efficient by modulating them and it can promote adaptations to exercise. The more exposure to lactate, the more you can gain.
We recommend using ExoLactate® Gel before and/or during exercise. The easiest way to use it is replicating your current carbohydrate intake strategy, and starting progressively from 1 or 2 gels per hour. Lactate is oxidised faster than carbohydrates, so consider taking it 5-10 minutes before desired effect. It is suitable for training sessions and in competition. Rehearse the protocol in training and make sure the body adapts to it (4-6 sessions; gut training) before racing.
Use the interactive calculator above to generate a fuelling protocol based on intensity and duration of your session. Consider that >3 gels per hour (120 g CHO/h and 20g Lactate/h) is a high performing practice in TDF, Ironman orTrails in elite athletes. Be aware of your metabolic demands and capacities, and don´t try to copy elite athletes without the recommendation from a professional.
ExoLactate® Gel can be used as a gel or diluted in water. Our texture mixes up with water nicely. Through experimentation, we have learned that our high elite athletes love adding our gel to a drink (soft flask or bottle) so they can meet their hydration demands while fuelling without compromises. You can dilute 1-2 gels in 500ml, or according to your preference.

What is ExoLactate®?
ExoLactate® is an exogenous lactate formulation designed to provide lactate directly to the body's metabolic systems. Lactate is a molecule naturally produced by humans and plays a central role in energy metabolism, exercise performance, recovery and cellular communication.
Is ExoLactate® suitable for all sports?
ExoLactate® has been developed to support athletes participating in endurance, intermittent and high-intensity sports where efficient energy delivery and performance maintenance are critical. It can be incorporated into a broader race or training nutrition strategy according to the specific demands of the sport and athlete. Exolactate® will benefit both low intensity exercise and hard explosive efforts.
When will I start to notice the effects of ExoLactate® Gel?
ExoLactate® has been designed for rapid absorption and utilisation during exercise. Under normal conditions, its effects may begin to be noticeable approximately five minutes after the first intake, depending on factors such as exercise intensity, nutritional status, and individual physiology.
For best results, we recommend following the usage guidelines provided on the product packaging or by your sports nutrition professional.

What happens after consuming ExoLactate®?
Following ingestion2,4:
- Lactate becomes available as an oxidative fuel
- Lactate enters existing physiological lactate shuttle pathways
- Multiple tissues can utilise lactate for energy production
- Lactate may participate in metabolic signaling processes
Can ExoLactate® Gel be combined with other sports nutrition products?
Yes. ExoLactate® can be integrated into most sports nutrition protocols and may be used alongside hydration products, electrolyte supplements, and additional carbohydrate sources. Athletes should always consider their total carbohydrate intake and individual gastrointestinal tolerance when combining products during exercise.
Can ExoLactate® improve athletic performance?
Current scientific evidence suggests exogenous lactate may potentially 3,4,5,6,7 :
- Support oxidative metabolism
- Provide an additional fuel source
- Improve energy transformation efficiency
- Contribute to glycogen sparing
- Assist recovery processes
- Support prolonged exercise performance
Can ExoLactate® support recovery?
Potentially. By delaying fatigue and minimising the impact of the exercise in the body, Lactate supplementation can support recovery from exercise. Moreover, some data suggest that neuromuscular function and glycogen - energy status can be promoted after lactate supplementation. Over consecutive days, Exolactate could optimise recovery from exercise.Contrary to traditional beliefs, recovery is not simply about eliminating lactate. Lactate is continuously recycled and reused throughout the body. Efficient lactate turnover is considered a hallmark of metabolic fitness 5,6.
Is ExoLactate® related to longevity research?
Potentially, and mostly in the Lactate only version. Emerging research is investigating lactate's role in mitochondrial function, brain health, metabolic flexibility, cellular adaptation and healthy aging. Whilst this field is still developing, lactate biology is becoming increasingly relevant within longevity and performance science 6,7.
Why is ExoLactate® generating so much interest?
Because it is built upon one of the biggest paradigm shifts in modern physiology.1,2
For decades, lactate was misunderstood. Today, science recognises lactate as:
- A major fuel source
- The main gluconeogenic precursor
- A metabolic regulator
- A signalling molecule
- A key component of exercise performance
- A contributor to brain metabolism
- An important player in recovery and adaptation
Is ExoLactate® safe?
Lactate is a naturally occurring metabolite present in all humans. Current scientific evidence suggests exogenous lactate formulations demonstrate a favourable safety profile in healthy individuals when used appropriately4,6.
Individuals with underlying medical conditions should consult qualified healthcare professionals before beginning any supplementation protocol.
Individuals with underlying medical conditions should consult qualified healthcare professionals before beginning any supplementation protocol.
Is ExoLactate® considered doping?
No. ExoLactate® does not contain any substances prohibited by the World Anti-Doping Agency (WADA) and is designed to support athletic performance through nutritional strategies rather than pharmacological intervention. ExoLactate® delivers carbohydrates and exogenous lactate as nutritional ingredients intended to support energy availability during exercise.
ExoLactate® is a sports nutrition product, not a medical product. As with any nutrition product used in elite sport, athletes are encouraged to follow their organisation's supplementation policies and consult qualified professionals if they have specific anti-doping questions.

Wasn't lactate considered a waste product?
Historically, yes. For much of the 20th century, lactate was believed to be responsible for muscle fatigue, acidosis and reduced athletic performance. Modern physiology has fundamentally changed this understanding. Research led by Professor George A. Brooks at the University of California, Berkeley demonstrated that lactate is continuously produced and utilised under both aerobic and anaerobic conditions. Rather than being metabolic waste, lactate acts as a circulating energy source and signaling molecule¹²³.
What is the Lactate Shuttle?
The Lactate Shuttle Theory is one of the most important concepts in modern exercise physiology. Originally proposed by George Brooks in the 1980s, it describes how lactate moves between cells, tissues and organs to distribute energy throughout the body². Examples include:
- Muscles producing lactate during exercise.
- The heart using lactate as fuel.
- The brain consuming lactate during periods of increased demand.
- The liver converting lactate back into glucose.
Can muscles use lactate directly?
Yes. Modern research demonstrates that skeletal muscle both produces and consumes lactate continuously. Different muscle fibers exchange lactate as part of normal energy metabolism, helping optimise energy production during exercise.² In trained athletes, lactate utilisation capacity is often enhanced through adaptations in monocarboxylate transporters (MCTs), which facilitate lactate transport between tissues⁴.
Does the heart use lactate?
Yes. The heart is one of the most efficient lactate-consuming organs in the body. During exercise, lactate may become a preferred fuel source for cardiac tissue due to its rapid oxidative availability².
Can the brain use lactate?
Yes. Research has shown that lactate crosses the blood-brain barrier and can be utilised directly by neurons. Scientific studies suggest lactate contributes to:
- Brain energy metabolism
- Cognitive performance
- Learning processes
- Memory formation
- Neuroplasticity
Does lactate cause fatigue?
No. One of the largest misconceptions in sports science is the belief that lactate causes fatigue. Current evidence indicates lactate itself is not responsible for muscle burning sensations or exercise-induced fatigue. In fact, lactate production helps maintain energy generation during periods of high metabolic stress.² Today, many physiologists consider lactate part of the solution rather than the problem¹².
Is lactate only an energy source?
No. One of the most important discoveries of recent decades is that lactate also functions as a signalling molecule. Researchers now recognise lactate as a regulator of: Gene expression, Mitochondrial adaptation, Cellular communication, Metabolic flexibility, and Lipid metabolism. This signalling role has led some scientists to describe lactate as a "lactormone"⁴.
