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, yeast infections and BV.

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 yeast infections and BV it wards off. A healthy vaginal microbiome has been shown to lessen the risk of other vaginal health problems too.

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

Enhance your gut and vaginal microbiome alike

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.

Completely free from nasties

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 live, 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.

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. 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.

We recommend taking one tablet per day for at least 90 consecutive days. We recommend taking them orally in the morning, with or without food.

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.

With a monthly subscription, you get the most flexibility. You can cancel or pause anytime. Monthly subscriptions also come with 6% off the price of a one-off box.

Multi-month subscriptions allow us to provide the highest possible discount on your ProViotics order. We currently have 2 options — a 3-month subscription, and a 12-month subscription. You can't cancel your order if you commit to a longer subscription, but you do benefit from a larger discount. With the multi-month subscriptions, you also save carbon emissions as we ship your boxes up-front in 3-month installments. For best results, we recommend you commit to at least 3 months of using ProViotics continuously. Lactobacilli can take a while to repopulate your gut and vaginal microbiome. Your box will be shipped with a tracked delivery service ensuring you know exactly when it will arrive.

Yes, Daye's ProViotics safety profile has been recognized by the FDA and they are absolutely fine to take when pregnant or trying to conceive, and encouraged to take during breastfeeding to prevent mastitis.

Daye ProViotics contain bacteria grown in organic carrot juice, whereas most probiotic products are grown in milk cultures. They’re certified organic, and free from allergens like soy, dairy, nuts and gluten.
The bacteria we use is also freeze-dried, which means it retains its properties for longer, and you don’t have to store it in the fridge.
Each tablet contains 2.5 billion live cells of Lactobacillus plantarum GLP3. What's key about Daye ProViotics is that all of our cultures are live, which means they can reach your gut or vagina.

Whilst ProViotics are not a medication (so we can’t say that they “cure” yeast infections), we do know that our clinical trials show that Lactobacillus Plantarum are 99.8% effective against Candida, the fungus that causes yeast infections.
Our ProViotics work to replenish and maintain a healthy vaginal microbiome, which can help fight off yeast infections.

Great question. The answer is both!
We already know how important the gut is for overall health, but researchers are starting to unveil how the gut plays a role in vaginal health as well.
