Each 8-ounce serving of Contrex Natural Mineral Water provides 11.5 percent of the Recommended Daily Intake (RDI) of calcium and 5 percent of the magnesium RDI. Therefore, a one-liter bottle provides almost half the calcium RDI and 20 percent of the RDI for magnesium with no added calories—an easy solution to replenishing the minerals your body loses when working out.

Each month 2 lucky winners will be chosen at random to receive two free cases (twenty-four 1-liter bottles) of Contrex® Natural Mineral Water plus a goodie bag. Only available in the US.
