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

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