Sea water for sportsmen


Sea water brings two types of benefits to athletes:

  1. It is the best way to replenish salts lost through perspiration (especially important in long events: cycling, marathon, etc.).

  2. It is the quickest way to recover from exertion (and be better prepared for the next day's race or more intense training).

In addition, athletes who drink it report fewer injuries.

Professional cyclists

Congress in Colombia where Laureano Domínguez interviews the athlete J.C. Cardona and cites the experience of a professional cyclist whom, the first thing his new Italian team asked him to do, was to drink sea water.

Video transcription

(Laureano Domìnguez): examples of Juan Carlos (Cardona) and other sportsmen, because the county (La Ceja) has other great high-level sportsmen, and it is very nice ....

(Laureano Domìnguez): who did not arrive (the other great sportsmen) among other things because Rafael, whom you know, three times Pan American cycling champion, Rafael Infantino, had a very nice experience. Perhaps he had some problems because he would have come from Italy and had committed himself to participate in this congress. Maybe he had some problems ... (one moment please)... Rafael acquired the theoretical experience of sea water in the village and was afraid to start taking it. When he was hired by an Italian cycling team he had a big surprise, so much so that he spent all day trying to locate me by phone to tell me: "Laureano, the first indication from my coaches is that I have to drink sea water". So there he understood what he had found here, he did it backwards. Marlon Pérez, world cycling champion, experienced something similar, he too was among the guests at this conference, maybe he will come ...

Quinton Laboratories carried out a study on cyclists in which the benefits of sea water are confirmed (See the study here -in Spanish-)


The trainer Manel de la Varga recounted his experience in his blog, in an article entitled "Seawater 'beats' sports drinks", where he explained his performance improvements by drinking isotonic seawater, improving the records obtained by drinking water alone or commercial sports drinks.

(His website it's only found today in archive.org searching for "19.1. El AGUA DE MAR VENCE A LAS BEBIDAS DEPORTIVAS" -in Spanish-)

He's been drinking it for 7 years and hasn't been injured since. He has just attained first place in his category - aged 65-69 - at IronMan Barcelona 2014. IronMan is the world's toughest triathlon - 3.8km swim, 150km bike and 42km run, all non-stop. See the results here.

He has researched to find the best drink to combat dehydration in endurance sports, before, during and after the sports test.

For that, he ran a distance of 21 km on several occasions and ways:

The average run times he obtained were:

If we compare the result obtained with sea water and that with quality water and electrolytes, the time saved is 4 minutes!

If the race is a marathon (42.2 km), the runner can improve his time by 8 minutes and also avoid injuries, cramps and improve recovery time (only if there is isotonic sea water in the refueling points for athletes who want it).

Detailed data can be found on its website. In paragraph 19.3 there are also testimonies of other sportsmen who drink it.

About him he says:

Regarding the care he took to stay in shape, the cyclist was a faithful follower and regular consumer of Quinton sea water products since his own brother recommended it to him in 2006. He always confessed to being more recovered after intense efforts and more hydrated on hot days.

Two world champions explaining that they drink sea water in their daily lives.

In Spain there is a convent of nuns (Poor Clares) who have declared that there is no pope since Pius XII. As a result, their "bishop" has stolen their bank accounts and is trying to expel them from their monasteries. He says they had less than 6,000 euros. (Even more shameful act, for stealing good poor nuns of what little money they had. They are poor: they had to mortgage one of their monasteries). They ask for support (money, materials or diffusion of their situation). Their website is tehagoluz.com and their Instagram account.

As you can see, on 6/14/2024 I've added many articles.

In Spain you can buy sea water at cheap price at any diet store and some supermarkets. Examples: this diet store, this pharmacy (at higher price), this supermarket.

There is also an organic bakery making bread with sea water and sells it too.

There are 5 companies bottling and selling sea water because there is a lot of people drinking sea water on a daily basis.

If you at your country become a critical mass of people interested in sea water, companies offering it will arise.

So, it's in your hands, sharing this information meeting your friends, by phone or social networks, to make the conditions where these companies will appear and make sea water even more available to all the people.

Work in progress.
