Boric Acid

A gentle suppository compound that restores healthy vaginal acidity and keeps flora balanced.

What it is

Boric acid is a mild mineral compound made specifically for intravaginal suppository use. It is derived from natural boron minerals and purified for medical use. Formulated in gentle capsules for vaginal insertion, boric acid works locally to restore the natural acidic balance of the vagina (pH 3.8 to 4.5). This acidic environment stops unwanted yeast and unwanted bacteria from building protective layers.

Also known as: Medical-Grade Boric Acid, Hydrogen Borate

Key benefits

  • Restores and maintains a healthy acidic vaginal pH (3.8 to 4.5) so friendly flora can thrive.
  • Breaks down unwanted fungal cell structures locally without affecting the rest of your body.
  • Provides targeted local hygiene support to soothe vaginal discomfort and clear unwanted odour.

Amplified by probiotics

Boric acid is used strictly as a local vaginal suppository and is not absorbed into the body. It works in harmony with vaginal Lactobacillus bacteria (such as L. gasseri and L. rhamnosus). By keeping the vagina naturally acidic, boric acid creates the perfect environment for these friendly bacteria to grow. In turn, friendly bacteria produce lactic acid to keep your natural microflora balanced and healthy.

Typical dose

600 mg intravaginally per suppository (used for a maximum of 14 days per cycle)

The evidence

Evidence: strong

Clinical studies show that intravaginal boric acid suppositories work effectively for recurrent vaginal yeast discomfort (Iavazzo 2011, J Womens Health). Medical guidelines support using local boric acid to quickly restore normal pH levels and bring comfortable relief (Powell 2011, J Womens Health).
