Which vaginal probiotics should I buy?

Vaginal probiotics aim to support Lactobacillus-dominant vaginal flora. The strains with the most evidence are Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14, studied mainly as an adjunct to standard treatment for bacterial vaginosis to reduce recurrence. Benefits are strain-specific, so an unnamed strain at a high CFU count is not an upgrade.

How is cost per day calculated?

We divide the brand's UK list price by the number of days a pack lasts, using the pack size and the daily serving printed on the label. Where a brand does not publish both numbers we leave the figure blank rather than estimate it.

Are these products ranked or paid placements?

No. The table is ordered alphabetically and nobody pays to appear in it. We do not hold ratings, accreditations or trial results for individual products, so we do not publish any.

Can I take more than one of these together?

Often yes, but check the total dose of any nutrient that appears in more than one product, and check interactions with your medication with a pharmacist first. Iron in particular should only be taken when a blood test shows you need it.

Which probiotic strains work for vaginal health?

Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 have the most supporting data, mainly for reducing bacterial vaginosis recurrence alongside standard treatment.

Do vaginal probiotics stop thrush?

The evidence is weaker for thrush than for bacterial vaginosis. Recurrent thrush needs proper assessment rather than repeated self-treatment.

Oral or vaginal probiotics?

Both routes have been studied for GR-1 and RC-14. Oral is easier to stick with and has reasonable supporting data.

Prices are the brand's UK list price at the time of writing and change often. Cost per day is calculated from pack size and the label's daily serving, and is shown only where the brand publishes both. We do not accept payment for inclusion or placement.

When a supplement is not the answer

Bacterial vaginosis, thrush and trichomoniasis feel similar and are treated completely differently. New discharge with an odour, bleeding between periods, pelvic pain, or symptoms after a new partner should be assessed, not self-treated. Sexual health clinics test and treat quickly and free. A probiotic is a reasonable addition after diagnosis, and a poor substitute for one.
