THERMOTABS Salt Supplement Buffered Tablets 100 Tablets (Pack of 6)

When one sweats, one loses electrolytes primarily Sodium (salt) and Potassium. During the summer, and especially in the sun-belt in the U.S., one doesn't have to play three sets of tennis or run a marathon to sweat; one can work up a sweat going about one's everyday routine. Spring water and purified water normally do not contain significant amounts of electrolytes. For that reason, it is prudent to take an electrolyte supplement such as Thermotabs. If one is experiencing leg cramps while sleeping, this could well be a sign that one is deficient in electrolytes.
