The NUUN tabs are actually designed with pro athletes in mind , came about because gatorade……..just doesnt work and makes you more thirsty , the NUUN tabs replace salts and get into your system fast . I talked to this kid that just got out of the Army , one of his jokes was ” There is only one thief in the military , everybody else walks around looking for their sh*t ” . Thought that was pretty funny. Insoles for your boots work wonders , as we get older , things change , having more back problems or leg joint problems ? Insoles for your shoes may actually be the cure ……….its all connected .
