What is normal vaginal pH?
pH describes the acidity or alkalinity of a specific substance and is assigned a number on a scale of 1 to 14. Zero is considered the most acidic, while 14 is the most alkaline. When a substance is labeled as neutral, that usually means it carries a pH level of 7.
A normal vaginal pH of 5 or lower is thought to fall within the healthy range. It registers below the neutral mark of 7 and qualifies as acidic. When vaginal pH is higher (or more alkaline), the chances of developing an infection increase. That’s because as vaginal pH rises, unhealthy bacteria and yeast multiply and affect the reproductive and urinary systems. Numerous factors come into play when vaginal pH balance is disrupted.
