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 cannabinoid-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 post-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 CBD 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
CBD tampons did not cause any irritation to the vaginal mucosa.
TSS Risk Reduction
Daye’s CBD 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 CBD on Good Bacteria
CBD tampons had a positive impact on Lactobacilli growth, strengthening the vaginal microbiome.
Acute Systemic Toxicity
This study verified that CBD tampons do not systemically cause organ damage.
Material Mediated Pyrogenicity
The study has deemed that CBD 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 cannabinoids
The lack of regulation in the cannabinoid industry means that poor quality products have become the market standard. At Daye, we’re changing that and only use cannabinoids 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 CBD 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 CBD supplier owns the entirety of their supply chain — from farm to bottle, ensuring they have unprecedented quality control over the final CBD extract.
Medical Board
Our medical board comprises clinicians, researchers, and OBGYNs across the US, EU, and UK.
