Sweat Analysis - Sodium

Medion is the industry leader in electrolyte replacement and now we are offering sweat analysis for interested athletes. Your sodium levels can now be accurately measured and we can determine how much sodium you will need to ingest for every litre of sweat you lose during your activity. No more guess work required! Upon receiving your results you will also receive information on how to customize your sodium replacement using Medion products. Please see below for information on our testing kit instructions and order details.

Why Test Sodium?

The main and most important electrolyte lost in sweat is sodium (Na+). 
Sodium imbalances can occur due to excessive loss of electrolytes through sweat, and a haphazard training / racing fueling plan.

The electrolyte concentration of sweat can vary greatly from person to person. The sodium concentration of one liter of sweat can range from  300 mg to 3600 mg depending on the individual, and varies by diet, sweating rate, hydration, and degree of heat acclimation (39). Under-replacing your sodium losses can lead to various problems including dehydration, muscular cramping, headaches, gastrointestinal upset, nausea, fluid retention and hyponatremia. 

You lose sodium in different concentrations from various areas of the body.  By taking sweat samples from the 3 key body areas as indicated in our instruction kit we can determine your overall body sodium loss per litre of sweat. You simply mail the samples back to our laboratory, where a mass spectrometer is used to determine the sodium concentration.

Knowledge is power, and tightening up your electrolyte replacement to this level of accuracy gives you a definite edge in race nutrition!  Upon special request, we can test for additional electrolytes lost in sweat.
