Revite Magnesium Fizzy Tabs 10

This is the 10-tablet tube of Revite Magnesium Fizzy, the same dissolvable magnesium drink as the larger pack in a size that fits a gym bag, handbag or desk drawer. It is a good way to try effervescent magnesium before committing to a month's supply, or to keep on hand for race days, long hikes and heavy training weeks. Every muscle contraction uses calcium to tighten and magnesium to release. Magnesium also helps regulate the nervous system's stress response and supports normal heart rhythm and energy production.

A cramp halfway through a run or in the middle of the night is hard to ignore and easy to prevent. If you train hard, sweat a lot, take a water tablet or a stomach-acid reducer, or simply wake up with calf cramps, your magnesium stores are probably running behind what your muscles and nerves use each day.
