The rigorous science behind Daye tampons


We are committed to raising the bar in Gynae health. We invest heavily in research and development with the aim to bridge the gap in medical innovation. Our -coated tampons were our first step in our journey towards building a more comprehensive and holistic health platform.

Daye tampons are proven to be safe


We follow the golden standard in clinical trial design and mail.market surveillance to ensure the safety and suitability of our tampons. Here’s how we did it:

Placebo-controlled trials

Double blinded study design

Monthly vaginal screening on all participants

80 participants

Impact on the vaginal microbiome

The study has concluded that Daye tampons do not impact the vaginal microbiome negatively. In fact, the Coated was shown to increase the level of good bacteria (Lactobacilli).

TSS-associated toxin production

No detectable Toxic Shock Syndrome toxin was found on the Daye tampon after 8 hours of incubation.

Daye tampons are extensively tested

At Daye, we take your vaginal health seriously. In addition to our clinical trials, we have also conducted a number of biocompatibility studies to prove the long-term safety of our tampons.

Vaginal Irritation

Coated tampons did not cause any irritation to the vaginal mucosa.

TSS Risk Reduction

Daye’s Coated tampons reduced the production of TSS-causing toxins.

Toxicity

The tampons did not cause subacute or subchronic toxicity.

Abrasions of the Vagina

No abrastions to the vaginal walls have been detected during our studies.

Impact of Coated on Good Bacteria

Coated tampons had a positive impact on Lactobacilli growth, strengthening the vaginal microbiome.

Acute Systemic Toxicity

This study verified that Coated tampons do not systemically cause organ damage.

Material Mediated Pyrogenicity

The study has deemed that Coated tampons are free of pyrogenic substances which could cause fevers.

Ongoing Quality Control

Every part of our supply chain is rigorously tested. We ensure that Daye tampons are free from microbial contamination, fragments of heavy metals, and that they have just the right amount of CBD — with absolutely no THC.

Disclaimer: Human clinical trials have been completed and reviewed by independent clinicians as well as the above. At present, regulatory authorities mandate that only prescription drugs should make their clinical evidence available to the general public. As we are not regulated as a prescription drug, we do not make our studies available publicly, so we can stay compliant with regulations. If you are a researcher and you'd like to review our data, please contact our customer care team and we'll send you a data pack.

Real-life Efficacy Data

We are committed to radical transparency, and collect more Post-Market Surviellance (PMS) data, than most pharma companies out there. Our data is reviewed by an independent board of Medical Advisors, so we can continue to ensure the quality, efficacy and safety of our tampons.

Pharmaceutical-grade

The lack of regulation in the industry means that poor quality products have become the market standard. At Daye, we’re changing that and only use produced to pharmaceutical-grade standards. This means:

CO2 extraction

An extraction method which removes the need for solvents, which in turn ensures the end product is free from chemical residues.

THC-free

Our exclusive supplier has a patented technology for removing all THC from the final Coated extract. So no, our tampons will not get you high, and yes, you can go through TSA with them.

Clean production

Closed-loop + stainless steel production: all our machine components are made of stainless steel. The production is fully isolated from air and outside contamination.

Single supplier

Our exclusive Coated supplier owns the entirety of their supply chain — from farm to bottle, ensuring they have unprecedented quality control over the final Coated extract.

Medical Board

Our medical board comprises clinicians, researchers, and OBGYNs across the US, EU, and UK.
