The seawater that resurrected Rafa Nadal and athletes around the world are swearing by

3 May 2023 | Jonothan Smith

Dehydration, fatigue, cramps and lactate acidosis are all common symptoms that most athletes or high level performers have experienced at some point in their lives. However, when it comes to performing at our best, these feelings can be debilitating. Despite our best efforts to push through the discomfort, our bodies often fail to respond as we want them to.

One of the main culprits of dehydration is fluid and electrolyte loss, which can be accelerated in hot and humid conditions, especially when combined with physical exertion.

Drinking more water may seem like a simple solution, right? Unfortunately over consumption of water may actually have the opposite effect, as it dilutes the mineral concentration of your blood. Over hydrating with water can lead to hyponatremia, a condition where the sodium concentration in the blood becomes dangerously low.

Minerals and electrolytes play a vital role in regulating your bodies fluid balance, as well as numerous other physiological processes including muscle function, nerve transmission and maintaining proper pH levels.

In order for these various physiological processes to occur, we need all 78 essential minerals in the correct amounts. It's important to note that the body requires different amounts of each mineral, and deficiencies or excesses of certain minerals can lead to health problems.

‚ÄúEvery cell in the body requires minerals to function‚ÄĚ

Nadal’s magic potion

Let's take Rafael Nadal, one of the greatest tennis players of all time, as an example. During his third-round match against Tim Symyczek at the Australian Open, Nadal faced a significant challenge. Despite winning the first set, he began to struggle due to the high temperatures and humidity, which led to heatstroke and dehydration. However, his coach provided him with a mysterious packet that helped him turn things around and eventually clinch victory. This packet contained a natural source of essential minerals and electrolytes, seawater.

Why Seawater?

While there are many solutions sold promising to address our mineral and electrolyte deficiencies, they often fall short in delivering promised results or come with unpleasant side effects such as gut distress or long-term health implications from artificial ingredients.

Poor mineral bioavailability and only 2-4 minerals leads to minimal absorption

High sugar content causes energy spikes and can lead to insulin resistance

Artificial and even natural sweeteners such as stevia cause gut distress

‚ÄúSeawater is the only natural solution containing all 78 essential minerals in the correct ratios‚ÄĚ

Seawater naturally contains a mineral composition that closely resembles that of human blood plasma, making it highly bioavailable and easy for the body to absorb. It also contains electrolytes, which are critical for proper fluid balance, muscle function, and energy production. Additionally, it’s rich in marine co-factors, including enzymes, nucleic acids, and amino acids, which can help support overall health and well-being

Studies conducted by the University of Alicante and the Catholic University of Murcia in Spain have shown that seawater has a 100% immediate efficiency rate in restoring electrolyte balance and hydration levels in the body, which is especially crucial during competition.

Of course, we are not suggesting you find your nearest beach and grab a bottle full of seawater. Our oceans today are filled with contaminants, from micro-plastics to bacterias and heavy metals which make seawater unsafe for human consumption.

Fortunately, a laboratory in Spain has come up with a proprietary formula that converts seawater into the worlds most powerful mineral solution. Using a pharmaceutical grade lab, they double cold micro-filter seawater from phytoplankton vortexes (the areas of the ocean with highest mineral density). This preserves all nutrients, including 78 essential minerals, marine co-factors, enzymes, nucleic acids and amino acids in their naturally occurring form, whilst removing all potential contaminants. All batches of seawater are subjected to over 100 rigorous controls to rule out the presence of heavy metals, pesticides, petroleum derivatives, micro-plastics, harmful bacterias and any other potential contaminant. This process guarantees safety for human consumption.

This groundbreaking solution comes from a brand called Quinton, named after french physiologist Rene Quinton, who discovered the healing properties of marine therapy back in the eighteen hundreds.

“In our laboratory, we implement the protocols and recommendations of organizations such as the EFSA (European Food Safety Authority) and the AECOSAN (Spanish Agency for Food Safety and Nutrition), in addition to other in-house controls, thus ensuring the absence of contaminants such as heavy metals, oil derivatives, pesticides, radioactivity and pathogens.

It should be noted at this point that our pharmaceutical production unit complies with the¬†ISO 9001, ISO 14001, FDA's Food Supplements GMPs, GMPs¬†and GMP/NCF Cosmetics (ISO 22716) standards.‚ÄĚ Quinton.

Athletes across a range of sports, from Endurance events to tennis, F1 and NBA, have all turned to Quinton to help them perform at their best. By replenishing lost fluids and essential nutrients, Quinton has become a go-to solution for athletes seeking a natural and effective way to combat dehydration and maintain optimal performance levels.


All 78 Essential minerals and electrolytes in the optimal ratios for absorption

No sugar or artificial sweeteners

No artificial ingredients or flavours

100% natural, cold micro-filtered seawater

Rehydrate, remineralise, and optimise your performance while also improving your health and wellness. Here are some reasons why Quinton is an excellent choice:

The mineral composition of Quinton is almost bio-identical to that of human blood plasma, making it 100% effective for absorption. Unlike synthetic or plant-based minerals used in most electrolyte solutions, Quinton's minerals are easily absorbed by the body, saving precious resources from being excreted.

By giving your cells the essential nutrients they need to produce ATP, Quinton can help increase your energy levels, allowing you to perform at your best.

Contains no artificial ingredients, calories, sugar, or sweeteners. Even natural sweeteners like stevia can disrupt communication between gut bacteria (quorum sensing), so Quinton avoids using them altogether.

Contains the full spectrum of minerals, not just the two or three most commonly used. Mineral interdependency is an essential concept to consider when it comes to our performance. Minerals work together in a delicate balance, and their absorption and utilisation is influenced by the presence of other minerals - read more about mineral interdependency

Improved cognitive function

Electrolytes such as sodium and potassium are essential for proper brain function, which can help improve cognitive performance during exercise.

How it works:

A recent study investigated the effect of micro-filtered and sterilised seawater (SW) ingestion on running performance in a hot environment - read more. The study found that compared to pure water, SW ingestion resulted in a significantly lower concentration of lactate after running exercise, indicating the ergogenic effects of SW ingestion on running performance and lactate production.

When it comes to supporting our bodies and maintaining optimal health, minerals and electrolytes play a crucial role. They are essential for a wide range of physiological functions, from bone and muscle health to cognitive function and immune support. But not all mineral supplements are created equal.

One of the most significant differences between Quinton and many other mineral supplements is the number of electrolytes it contains. While most supplements on the market contain only 2-5 electrolytes, Quinton contains all 78 electrolytes and trace elements found in the human body. This means you're getting a much more comprehensive range of minerals to support your performance. Also, don’t forget about the role mineral interdependency plays in optimal absorption, as discussed in our blog post here.

Many mineral supplements on the market contain unwanted sugar or artificial sweeteners that can disrupt gut health, contribute to chronic health issues like insulin resistance and diabetes. Even natural sweeteners like Stevia are shown to disrupt quorum sensing in the gut (communication between gut bacteria). Quinton, on the other hand, is completely free of sugar and sweeteners. This means you can get the minerals your body needs without any unwanted ingredients or sugar spikes.

Some minerals are poorly absorbed by the body, which means you may not be getting the full benefit of the supplement. Synthetic minerals are not as easily absorbed by the body as natural, bioavailable sources. Poor mineral bioavailability can lead to increased energy expenditure through eliminating unabsorbed minerals. Quinton is made from 100% natural seawater processed using a unique filtration method that preserves the natural balance of minerals and electrolytes. This ensures that you're getting a bioavailable source of minerals that your body can easily absorb and use.

In summary, if you're looking for a comprehensive and natural mineral supplement, Quinton is an excellent option. With all 78 electrolytes and trace elements, 0 sugar or sweeteners, and immediate absorption, it's designed to support your overall health and wellbeing. Plus, it's 100% natural and made from bioavailable seawater minerals. So why settle for less? Choose Quinton for optimal mineral support.


I used to struggle to sleep with hearing my heart beat in my ear. Turns out it was a mineral imbalance and Totum nite helped get rid of this!
