Daye was founded to raise the standards in female health by creating sustainable, category-defining products and services that bridge the gender gap in research and innovation.

That’s why we’re starting by making tampons worthy of your body, needs and lifestyle.

Our gold standard of tampons

Tampons are not classified as medical devices in Europe, which means there are currently no mandatory manufacturing guidelines in the tampon industry. 

In fact, plasters have more stringent manufacturing guidelines and regulatory compliance standards than tampons (which go inside the most absorbent part of your body every month).

Manufacturing standards

Even though we're not required to do so in Europe, we treat our tampons as medical devices, producing them to the highest possible pharma-grade standards. 

Daye tampons are produced in cleanrooms and sanitised with gamma ray sterilisation to eliminate any microbial contamination (reducing the risk of vaginal infections and TSS).

We also batch-test our tampons and test for pesticides, dioxins, heavy-metals, CBD content (to ensure it’s 30%), and THC content (to ensure it’s 0%). 

We work within our accredited ISO13485 medical device standard framework to ensure the highest standards for our products.

This is the highest quality standard in medical devices, which ensures all of our operations – from production to testing to post-market surveillance – are executed to the same level of care as the one applied to stents, hip replacements, and other medical devices.

This ensures end-to-end traceability, from raw materials to finished good, and unparalleled quality management. So if we identify a problem with a certain tampon, we can examine all the raw materials that went into it and determine if there are issues with other batches. 

A protective sleeve to avoid tampon shedding

Tampon fibre loss is a common issue where tampons shed inside the vaginal canal, leaving fibres behind. These pockets of fibres become an ideal breeding ground for thrush and BV-causing bacteria.

Many tampon sleeves shift during insertion and removal. That’s why we devised a permeable, protective cotton sleeve that wraps around the body of the tampon and doesn’t budge, rip, or deteriorate. This eliminates the risk of the tampon fibre loss as well as pathogen colonisation.

For CBD tampons, we’ve developed a technology that ensures that the outer layer of our tampons are coated with CBD, so the compound can be continuously administered (rather than being absorbed by the tampon itself). We’re continuously improving our coating technology to make Daye CBD tampons even more effective!

Using the best tampon ingredients 

Even though we’re not legally required to disclose our tampon ingredients or manufacturing process, we believe in full transparency with our entire supply chain. Daye tampons are 100% free of plastic, rayon, chlorine bleach, dioxin, phthalates and fragrances – all of which have been commonly found in mainstream tampons. 

Where do our tampon ingredients come from? 

Daye believes in implementing radical transparency, and that extends to our tampon manufacturing process. Customers should be given the tools to make informed choices based on their values and standards (since tampons end up in your vagina, it’s good to know where they’ve been!).

We have 3-year exclusivity agreements in our supply chain for cotton and CBD, allowing us to maintain long-term relationships with suppliers (who are required to adhere to strict supplier conformity agreements).

This incentivises our suppliers to continuously provide the best products, with all agreeing to test for microbial contamination – before delivering the materials to us. 

Sustainable, certified & organic cotton 

Our cotton is sourced from a sustainable, unbleached, certified organic cotton farm in Germany, grown without herbicides and pesticides. 

Pharmaceutical-grade CBD ensures safe, effective dosing

Our CBD supplier, PBG, is the only European company to own the entirety of their supply chain – from seed to bottle – ensuring unprecedented quality control. They’re also the only CBD supplier to own IP for pharma-grade CBD extraction that is 100% THC-free.

Our CBD is produced in a cleanroom using only stainless steel machines (as per FDA medical device standards). The CBD compound is then triple-tested for potency and the lack of solvents, impurities, heavy metals and microbial contamination. To further test for safety, we also took the full FDA biocompatibility and pre-clinical microbiology panels. 

Daye Tampons

We’re thrilled to offer Nude (non-CBD) and our clinically validated CBD tampons, both which come in Regular and Super varieties.

Daye Nude tampons

Our Nude tampons may be plain, but definitely not boring. They’re what we believe every tampon on the market should be: made of pesticide and dye-free organic cotton fibres, sterilised for safety, and with a protective sleeve to prevent fibre loss. Basically, a product that is worthy of your body, needs and lifestyle.

Daye CBD tampons

Healthcare should be personalised, which is why we launched the world’s first CBD tampon. Even though 9 out of 10 people who menstruate experience dysmenorrhea (menstrual cramps), there’s very little research on what causes it, let alone how to treat it. 

Second only to the brain, the vaginal mucosa contains the highest concentration of cannabinoid receptors in the human body, making it an ideal place to apply a CBD compound. We spent a lot of time researching, developing and patenting our formula for safe, effective and localised CBD application.  

Our CBD tampons are just like our Nude ones, but with the added benefits of high-potency (30%), full-spectrum CBD. All with 0% THC.

Our science-backed approach

At its core, Daye is an R&D company. We exist out of the need for female-focused medical innovation. We've conducted extensive clinical studies (e.g. double-blind, crossover, multi-centred) on our tampons, and since Day one, we’ve worked alongside regulators, including the FDA, MHRA, and EMA.

We’re committed to working with medical experts who are dedicated to raising the standards of female healthcare. Our research has been largely supported by the Center for Applied Science and Innovation at the Sofia Medical University, Faculty of Biology, as well as our clinical trial partner, IMR, the University of Liverpool and Liverpool Women’s Hospital (the UK’s largest hospital, which helps deliver 9,000 babies a year!).

Our goal? Create the most eco-friendly tampon

Did you know that mainstream period products like tampons and pads are made from 90% plastic, and along with their packaging they generate 200,000 tonnes of waste per year in the UK alone?

When you’re dealing with cramps, heavy bleeding and leaks, the environment might not be the first thing on your mind – we totally get it. We believe manufacturers and brands should be doing the legwork in order to give people who menstruate more eco-friendly options. 

We want to leave an impact, not a trace. That’s why our products encourage people to shop with their values without compromising quality, accessibility or effectiveness. 

Sustainable packaging

We’re on a mission to make disposable period products as sustainable as possible. We aim to source all our materials through certified, renewable or low-impact extraction methods, and we invest in material innovation and analysing the life-cycle of our packaging and product. We’re also proud to be a CO-2 neutral operation!

So far, our sustainable packaging consists of bio-based recyclable sugarcane applicators, water-soluble paper wrappers, and boxes and mailers made from recycled paper. 

Fair labour

True sustainability involves more than just environmental impact: it also means ethical employment practices. 

Our UK production team is hired through Working Chance, a charity that helps women from the criminal and care systems find meaningful and fair employment. 

Our new Bulgarian production site will partner with Daughters Of Bulgaria, a charity that supports and employs survivors of human trafficking.
