This infographic debunks the myth that alkaline water can alter blood pH or prevent cancer, illustrating how stomach acid neutralizes it immediately and the body's robust pH regulation system maintains stability.

Short answer: Your body maintains blood pH at 7.35-7.45 automatically. Drinking alkaline water can't change that - stomach acid neutralizes it immediately.
