Menstrual Health Products

Tampons

Tampons designed to bring scientific rigour to menstrual care. Every Daye tampon is designed and tested to medical standards — engineered for safety, comfort, and maintaining vaginal health.

What they are

Daye offers two tampon variants:

  • Nude Tampon: GOTS-certified, organic cotton tampon designed for everyday menstrual use.
  • CBD Tampon: Identical in build, but coated with pharmaceutical-grade cannabidiol (CBD)derived from THC-free hemp extract. 

Both tampon variants are manufactured under ISO 13485 and GMP — the same frameworks used to produce medical devices and pharmaceuticals. Unlike conventional tampons, Daye Tampons are treated as medical products, meaning every component, process, and test is held to higher safety and biocompatibility requirements.

The Daye CBD Tampon is FDA 510(k)-cleared (K223883) for menstrual use and produced in compliance with EU MDR requirements. Its safety profile has been verified through pre-clinical and clinical studies assessing irritation, microbiome impact, and toxin production, with results reviewed by independent clinicians and Daye’s Scientific Advisory Board.

Innovative design & sustainable materials

Gamma irradiation

All Daye Tampons are sanitised using gamma irradiation, ensuring microbial safety from production to use.

Clean-room manufacturing

Daye Tampons are assembled inside a clean-room environment, protecting each unit from airborne or handling contamination and helping preserve vaginal microbiome integrity.

Metal detection

Before leaving the clean room, every tampon passes through metal detection sensors to prevent any risk of metal shedding or contamination during production.

Continuous lab testing

Every batch is screened for microbes, PFAs, and heavy metals to guarantee ongoing product purity and safety.

Why this matters?

The vaginal environment is one of the body’s most delicate ecosystems. Even small traces of contaminants, fibres, or microbes can disrupt its balance. By holding our tampons to medical-device standards — from sterilisation to clean-room assembly — we help protect the vaginal microbiome and set a new benchmark for what safety in period care should mean.

How CBD tampons work

The vaginal and uterine tissues are rich in endocannabinoid receptors (CB1 and CB2) — components of the body’s innate endocannabinoid system, which plays a key role in modulating local pain perception, inflammation, and immune function.


The CBD coating on Daye Tampons interacts locally with these receptors within the vaginal canal.  High-performance liquid chromatography (HPLC) studies indicate that CBD applied intravaginally remains localised, with no detectable systemic absorption, ensuring it is non-psychoactive and confined to the area of use.

In simple terms: Daye’s formulation is designed to support vaginal comfort by engaging the body’s own receptor network — locally, precisely, and safely.

Purity & quality by design

To ensure consistency and safety, our CBD extract is produced to pharmaceutical-grade standards by a single, traceable supplier.

Supercritical CO₂ extraction

a solvent-free process that ensures a pure, clean, and chemical-residue-free CBD extract.

THC-free formulation

our partner uses patented purification technology to remove even trace amounts of THC from the final CBD extract, so our tampons are completely non-psychoactive — and TSA-safe. To confirm this, we independently test the raw CBD extract from our supplier, as well as the final CBD tampon batches.

Tested for safety & consistency

Every batch of CBD Tampons undergoes independent laboratory testing to verify:

Uniform CBD concentration

Non-detectable THC (<0.01 %)

Absence of microbial contaminants and residual solvents

Why this matters?

The vaginal mucosa is one of the body’s most permeable tissues — meaning substances applied there can be rapidly absorbed and can influence the local environment. That’s why purity, consistency, and control aren’t optional; they’re essential.


By holding our CBD tampons to medical-device manufacturing standards—including biocompatibility testing, controlled coating methods, and independent lab verification—we ensure each unit delivers a precisely measured, contaminant-free formulation. This safeguards the vaginal microbiome, minimises irritation risk, and ensures predictable performance with every use.

No Vaginal Irritation

Non-Toxic

TSS Risk Reduction

Impact of CBD on Good Bacteria

No Abrasions of the Vagina

Clinical validation & safety evidence

Daye Tampons undergo laboratory and clinical testing to verify their safety, purity, and compatibility with the vaginal ecosystem.

Our validation spans every stage of product safety — from clinical trials and biocompatibility testing, to how the tampon supports vaginal microbiome balance. Production batches are independently lab-tested, and monitored through continuous post-market surveillance to ensure consistent safety and performance.

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). Read study

TSS-associated toxin production:

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

Biocompatibility (ISO 10993)

Certified testing labs verified no irritation or toxicity when used as intended.

  • Vaginal Irritation: CBD tampons did not cause any irritation to the vaginal mucosa. Read study
  • Toxicity: The tampons did not cause subacute or subchronic toxicity. Read study
  • Abrasions of the Vagina: No abrasions to the vaginal walls have been detected during our studies. Read study
  • Impact of CBD on Good Bacteria: CBD tampons had a positive impact on Lactobacilli growth, potentially strengthening the vaginal microbiome. Read study
  • Acute Systemic Toxicity: This study verified that CBD tampons do not systemically cause organ damage. Read study
  • Material Mediated Pyrogenicity: The study has deemed that CBD tampons are free of pyrogenic substances which could cause fevers. Read study

Why this matters?

Daye CBD Tampons have been clinically and pre-clinically tested to confirm they’re gentle on vaginal tissues, non-toxic, and compatible with the body’s natural microbiome. Studies found no irritation, abrasions, or systemic effects - meaning they’re safe for sensitive tissue and regular use.

Всички тампони Daye се произвеждат в обект, отговарящ на стандарти за производство на медицински изделия, включително ISO 13485 и GMP. Нашите комплекти за тестване се анализират от партньорски ISO9001-акредитирани лаборатории. Както при всеки диагностичен тест, резултатите трябва да се тълкуват от квалифициран здравен специалист, като се вземат предвид симптомите и медицинската история на пациента. Daye също така предлага възможност за запазване на часове при независими здравни специалисти за клинично тълкуване и грижи.
