More Info Why should we be concerned about pH levels? Since most of the body is water-based (50-60%), the pH level has profound effects on all body chemistry, health and disease. All regulatory mechanisms (including breathing, circulation, digestion, hormonal production) serve the purpose of balancing pH, by removing caustic metabolized acid residues from body tissues without damaging living cells. If the pH deviates too far to the acid side or too far to the alkaline side, cells become poisoned by their own toxic waste and die. Just as acid rain can destroy a forest and alkaline wastes can pollute a lake; an imbalanced pH corrodes all body tissue, slowly eating into the 60,000 miles of veins and arteries like corrosives eating into marble. If left unchecked, an imbalanced pH will interrupt all cellular activities and functions, from the beating of your heart to the neural firing of your brain. Thus, alkaline water serves as a great way to keep your blood pH alkaline and you more healthy.
