In response to your PM dragon....


When you ingest plain water you will cause water to be absorbed into your bloodstream, this has the effect of diluting your blood instantly. In reponse to this dilution your kidneys will start to extract water to try and stabilise the blood dilution. So whilst you know you need water to stay hydrated, your kidenys will be working against you!

One of the mechanisms your kidneys use to monitor the blood dilution is the electrolyte levels (pricipally Sodium & Potassium), by simultaneously ingesting water and fresh electrolyte (in this case in teh form of teh Lo-Salt) you will trick the kidneys into not reacting so harshly to the water intake. This has the effect of allowing your water levels to stabilise more efficiently around your organs and muscles without the kidneys being party poopers!!

Soft drinks companies caught onto this effect and started to release "isotonic" sports drinks, supposedly which mimic the natural electrolyte and mineral balance of normal blood (approx 8-9g/L). In truth these drinks are usually hypotonic, in thta they do not possess quite as much electrolyte and mineral as the blood, simply because this solution is also known as saline and happens to taste horrible!!


The trick of mixing Lo-Salt with the water is creating a very simple "isotonic" drink similar to gatorade or lucozade sport, but without the expense and carbohydrates!!


I will add that you could increase the level of Lo-Salt you put in your water, I've found that a teaspoon (6g) tastes ok though in 2 litres of water so this is my personal recommendation!
