Are CBD tampons safe?


Are CBD tampons safe?

In short, yes our CBD tampons are safe. However, we know there’s a lot of misinformation on the internet and we’re here to provide you with the full story and research behind CBD tampons.

After extensive clinical validation, we can confidently confirm that Daye’s CBD tampons are safe for vaginal use. They are, however, a novel product, which understandably attracts a lot of scrutiny, especially on the internet. We always welcome scepticism, and in true Daye spirit, want to provide you with the full story on the research behind our tampons.


Here at Daye, we go above and beyond to ensure the safety of our products. While regulations around launching a new tampon to market do not require companies to run clinical trials, we simply didn’t feel comfortable providing you with Daye products before clinicians had signed them off.

We spent the first 2 years of our company‘s journey conducting extensive lab tests and double-blinded clinical trials, which demonstrated the safety and efficacy of our tampons. 

The lab tests we conducted were in accordance with the criteria set out by the European Medicines Agency and The US Food and Drug Administration. Through these, we were able to confirm that Daye‘s nude and CBD tampons:

  • Do not increase the risk of TSS (toxic shock syndrome)
  • Do not disrupt the vaginal microbiome and pH levels 
  • Do not cause vaginal irritation or tearing 
  • Do not result in toxicity 

We further partnered with the Institute for Medical Research to conduct a double-blinded clinical trial with patient volunteers. Each participant received a full vaginal microbiome screen for each month of using Daye tampons. This is how we could verify that our products do not increase your risk of vaginal infections like yeast (known often as thrush) or bacterial vaginosis, nor did they decrease the level of good bacteria (lactobacillus) in the vaginal canal. 

We further ensure the safety of our products by regulating our production and post market surveillance processes under the internationally recognised ISO13485.

We‘re proud to have our quality systems audited to the same standards as heart stents, brain implants, and prosthetic limbs. 

Post production, batches of Daye tampons are tested in independent laboratories, ensuring they are:

  • Uniform in their cannabinoids content 
  • Free from Tetrahydrocannabinol (THC), the main psychoactive ingredient in cannabis
  • Free from microbial contamination
  • Free from heavy metals 

Further, our Clinical Advisory Board (Dr Rufus Cartwright MD(res) MRCOG, Dr Bahijja Raimi-Abraham, Prof Judith Stephenson) comprises some of the leading minds in female healthcare today. We gather quarterly to analyse the real life usage data from our customers. So far, we’ve gathered over 60,000 data points on how our tampons work outside of a clinical setting,people with periods. This post market surveillance has so far demonstrated that Daye’s tampons have no significant side effects, and they:

  • Do not cause UTIs
  • Do not result in vaginal infections 

Customer safety is an ongoing commitment for Daye, and we will continue reinvesting our profits into further studies to advance female health innovation. If you are interested in a white paper outlining the full studies, please contact us on hello@yourdaye.com

Daye tampons are manufactured in accordance with medical device standards, including ISO13485 and GMP. In order for a diagnosis to be confirmed, test results from the Diagnostic Tampon should be considered by a licensed healthcare provider alongside a patient's symptoms and medical history. Like every other diagnostic test, lab results are not sufficient for a diagnosis. Daye offers customers the option to connect with independent CQC-regulated healthcare providers virtually and in-person for a confirmed diagnosis. All prescriptions and treatments provided through the Daye platform are issued by third-party, independent pharmacists, who are also regulated under CQC and GPhC.
