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

The Daye Tampon is GOTS-certified and made from organic cotton, designed for everyday menstrual use.

Unlike conventional tampons, Daye Tampons are manufactured under ISO 13485 and GMP — the same frameworks used to produce medical devices and pharmaceuticals. Every component, process, and test is held to higher safety and biocompatibility requirements.

The Daye 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.

No Vaginal Irritation

Non-Toxic

TSS Risk Reduction

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.

TSS-associated toxin production:

All Daye tampons are manufactured at a facility compliant with medical device manufacturing standards, including ISO 13485 and GMP. Our testing kits are analysed by UKAS-accredited and CQC-registered partner laboratories. As with any diagnostic test, results should be interpreted by a qualified healthcare professional, taking into account the patient’s symptoms and medical history. Daye also offers the option to book appointments with independent, CQC-regulated healthcare providers for clinical interpretation and care. Any prescriptions or treatments offered via the Daye platform are issued by third-party, independent pharmacies regulated by the GPhC and CQC.
