MANILA, Philippines - Tapped from a naturally occurring underground source, Hidden Spring Natural Mineral Water contains beneficial minerals such as calcium, magnesium, and bicarbonate. Calcium is good for the bones and the digestive system, while magnesium can help regulate blood pressure and strengthen the immune system. As close as possible to natural water, Hidden Spring Natural Mineral Water undergoes a filtration process that eradicates impurities, while keeping these essential minerals intact. This ensures that Hidden Spring Natural Mineral Water is clean and can be good for the body. Certain kinds of water, while clean, may lack essential minerals, so they may not give the body some of the necessary benefits it needs. Other kinds are treated to remove the organic compounds that water naturally contains. Hidden Spring is water just the way Mother Earth made it, a refreshing drink that rehydrates and replenishes. It is available in leading supermarkets and convenience stores nationwide in 330ml, 500ml, 1.5L, and 1.5 gallon bottles.
