Any Questions?

P.Happi® is for women at all life stages. Women in our studies have ages that range from 18 to over 70 and reported improvements in symptoms such as odour, dryness, feeling more protected during every day life, stressful and fun times!

Yes, P.Happi® aims to give you the extra protection while your microbiome is suffering during antibiotic use. Great for active microbiota management during and after antibiotic use to strengthen your natural defences. Note that while B.Y.M.® 1405 is a bacterium, different antibiotics can impact B.Y.M.® 1405 differently, with Trimethoprim showing good compatibility.

Yes you can! P.Happi® is a non-hormonal serum meaning you are able to use it together with hormone based treatments.

Yes you can use P.Happi® together with your usual topical products. To get the best out both it may be beneficial to apply them at different times, a few hours apart to allow them to work.

We recommend you apply the serum around your triggers in addition to your AM and PM routine.

As there is a moisturising effect, applying the serum may help to improve comfort during sexual activity.  If you are applying the serum beforehand, avoid using condoms with spermicides.


You may want to also apply the serum afterwards if you are concerned about contamination. However, if you tend to pee after sex, after that.

Each bottle of P.Happi® contains enough for twice daily use for one month. Once opened P.Happi® should be stored in a cool, dry place and used within six months. It does not need refrigeration but can be stored in the fridge for maximum potency. Please do not freeze and keep it out of direct sunlight.

This little tube changed my daily life and made me feel comfortable again.

I tried the P.Happi serum and I felt a huge difference after just a few days! I was very surprised to see the effects so quickly as I was experiencing a very peculiar type of discharge which I tried to fight in many possible ways. I used many hygiene products or medication for several months and nothing was helping.

This little tube changed my daily life and made me feel comfortable again.

2. How would you describe your menopause stage?: Post-menopause
Feeling confident especially when travelling.

Really lovely to use. I don't use every day but have had no sign of UTI these past few weeks. Really appreciate the confidence it gives me when travelling especially long haul.

This could be a life changer for me.

I have had ongoing issues with MS bladder related problems and now Breast Cancer drugs have finished the job or so I thought! I am hoping your product has turned a corner for me, it feels different and less painful. After twenty years of antibiotics, bladder stretches and hiding from the dreaded catheters I think I'm seeing the light at the end of a long tunnel!

Thank you so much for all you are doing I will definitely be ordering more, this could be a life changer for me.
