A pH of 0 is totally acidic, while a pH of 14 is completely alkaline. A pH of 7 is neutral. Those levels vary throughout your body. Your blood is slightly alkaline, with a pH between 7.35 and 7.45 Alkalinity means that something has a pH higher than 7. The human body is naturally slightly alkaline, with a blood pH of around 7.4.
