What is hypertonic seawater?
Hypertonic seawater is the state in which oceanic liquid can be found while preserving its natural properties thanks to the AQP protocol. Among its main chemical characteristics, we can highlight a concentration of mineral salts of 33 gr/l, as well as an osmolarity of 2,400 mOsm.

According to this study, hypertonic seawater that has undergone cold microfiltration favours fatigue recovery thanks to:
- An increase in sodium to avoid hypotonic hyponatremia.
- An increase in bicarbonate that will prevent acidosis.
- Facilitates the supply of carbohydrates that the body demands.
- Facilitates hydromineral homeostasis.
Hypertonic seawater use for sports
Currently, hypertonic solutions are a great sport resource thanks to their ability to replace electrolytes. Given that excessive sweating (in which hyperhydration occurs at the expensive of the mineral component) could lead to significant sodium loss and consequently, a decrease in physical performance. In this case, hypertonic seawater significantly helps one naturally recover these minerals.
In addition, this aspect becomes more important during periods of high exercise intensity and hot environments. Taking into account that the average sweat rate in athletes is 1.5 litres per hour, with a concentration of approximately 35-40mmol/l solutes, excessive sweating can lead to hyponatremia, hypovolaemia and alterations in muscle conduction and contraction with the production of cramps. Therefore, it is of vital importance to keep well-hydrated and replenish lost minerals.
Diverse studies carried out by experts from the University of Alicante and the Departments of Prevention and Treatment of Athelete Injuries at the Catholic University of Murcia demonstrate the effectiveness of the use of cold microfiltered seawater as a 100% natural mineral supply to immediately address hypotonic hyponatremia in athletes.
