Those drinking Willow spring water have the unique opportunity to sample liquid that takes advantage of the surrounding landscape to infuse each drop with healthful properties. The presence of salacin and a healthy dose of calcium provide invaluable health benefits, with the beds made of gravel and sand helping form an aquifer to complete the perfection. This water first emerged more than eight centuries ago, with its remote location helping protect it from contemporary concerns. The natural filtration process involved is seen by many who drink Willow as one of the main components of being able to restore vigor to an individual. The salacin is derived from rainwater that drips from the ancient trees that surround the area, while the water that touches the deposits of limestone are where the calcium enters the picture. That makes Willow a perfect supplement who may have health issues related to bones or teeth.
