Dear Mark,
I did the hydration test some weeks ago and I was not surprised with the result: I seem to loose an awful lot of Sodium during my exercise. Since I take the purple Sodium capsuls before and during my workouts, my headache has disappeared and I can also concentrate on work after my runs and cycle rides. I was getting used to it, but it’s a massive difference and I cannot beliefe that I put up with headaches and lack of concentration after sport for so long.
I not only feel much more aware during and after sport, I also feel I can go the extra bit on long workouts- happy times!
A big thank you 🙂 Sybille
