Can water be a good source for calcium?
No. Water is an extremely poor source of calcium. Get your calcium – and the rest of your minerals – from food. Spinach, turnip greens, mustard greens, and collard greens are excellent sources of calcium. Dairy foods are also an excellent calcium source. Beyond H2O’s focus is effective hydration. The purer the water, the better the hydration. Anything added besides the required minerals to water will slow down the hydration process.
