Answer

Alkaline water has a higher pH level than normal tap water. Some proponents say that alkaline water can neutralize acid in your bloodstream, boost your energy level and metabolism, and help your body absorb nutrients more effectively. Others say that alkaline water can help you resist disease and slow the aging process. However, there's no scientific proof that any of these claims are true. For most people, plain water is best.
