Boost your microbiome with ProViotics

Meet your vaginal flora

Like your gut, your vagina is home to billions of bacteria (some good, some bad). These make up your vaginal microbiome. When it doesn’t contain enough good bacteria, you’re at greater risk of infections like STIs, thrush and BV.

ProViotics help you create a microbiome environment that promotes the growth of good bacteria, while also making it hard for harmful bacteria to survive.

Is your vaginal microbiome surviving, or thriving?

Having a high level of good bacteria (Lactobacilli) means your vaginal microbiome is thriving.

Why should you care? Because it’s not just thrush and BV it wards off. A healthy vaginal microbiome has been shown to lessen the risk of other vaginal health problems too.

ProViotics can be taken vaginally to deliver 2.5 billion live good bacteria directly to your vaginal microbiome.

A healthy vaginal microbiome is associated with:
Helps prevent recurring vaginal infections like thrush and BV
A lower risk of contracting STIs and pelvic inflammatory disease
A lower risk of developing certain gynae cancers
A lower risk of experiencing miscarriage and preterm birth

Enhance your gut and vaginal microbiome alikec

Lab tests have confirmed that ProViotics survive in the acidic environments of both the gut and the vagina. This means they reach you alive, unlike other brands of probiotics. You can take them orally to help with that pesky PMS bloat and your digestion. Studies have shown that making them a part of your daily self-care routine can lead to enhanced energy levels too — a win-win for the body and the mind.

Lactobacillus plantarum GLP3 is extracted from the snowdrop flower, and grown in organic carrot juice. It’s completely free from additives and nasties — it doesn’t even come in a capsule. With ProViotics, all you get is effective, cold-pressed lactobacilli. The good stuff.

Backed by science

We work closely with our medical advisory board and a select group of clinical institutions to ensure our research gets an expert seal of approval.

Certain good bacteria can contribute to the overall health of the vaginal microbiome. A balanced vaginal microbiome is defined as having a ratio of good to bad bacteria of 80 to 20 or better. Daye's ProViotic was developed specifically to increase the ratio of good bacteria in the vaginal canal, strengthening the overall health of the vaginal microbiome.Simon Gaisford FRSC CChem SRPharmSProfessor of Pharmaceutics, UCL School of Pharmacy

Frequently asked questions

Daye ProViotics are proven to reach your gut alive, so they can be taken once daily as a supplement, on an empty stomach or with food. They’re also good to take after a course of antibiotics, to replenish the good bacteria in your vaginal and gut microbiome, which can minimise the risk of thrush or microbiome dysbiosis. For best results, you need the lactobacilli to have time to repopulate your microbiome. That’s why we recommend taking them for a minimum of 90 consecutive days.

Lactobacillus Plantarum GLP3 (grown in organic carrot juice), and nothing else!

Store in a cool dry place. ProViotics are freeze-dried, so you don’t have to refrigerate them.

Our ProViotics tin is made of endlessly recyclable aluminium, and we ship them to you in a recycled cardboard box. The refill pouch is fully compostable (even though it may look like plastic!) and is safe for both home and industrial composting. The ProViotics bio-based applicators are made of sustainably sourced, renewable sugarcane.

Possibly! Research suggests that supplementing with good bacteria, especially Lactobacilli, can prevent UTIs. Lactobacilli dominate the urogenital flora in women, and it has been suggested that replenishing it with lactobacilli may protect against UTIs by fighting pathogens like E.coli, which cause UTIs. Read more about how to treat and prevent UTIs in this article.

We recommend taking one tablet per day for at least 90 consecutive days. If you take them orally, we recommend taking them in the morning, with or without food. If you’re taking them vaginally, we recommend taking them in the evening before going to bed. Expect increased vaginal discharge if you take them vaginally for the duration of use. Don’t worry, ProViotics wash off your underwear completely in lukewarm water.

Not really! Lactobacilli have long and safe history of use in humans. As they are vegan and allergen-free it’s unlikely that you will have a negative reaction.
