pH is a scale of measurement between things that are alkaline (non-acidic) and acidic. The scale ranges from 0 – 14, with 14 being the most alkaline and 0 being the most acidic. Water is pH neutral and has a pH of 7.
A healthy vagina has a pH balance of 3.8 – 4.5, which is fairly acidic (about the same as a tomato).
The vagina's "good bacteria" produce lactic acid, which keeps the bad bacteria away.
However, when the vagina is off-balance (too alkaline), the bad bacteria thrive and can mess it all up. Please read out home page to learn more.
