Been using this product for two months, and have to say it is making my life so much easier. I struggle with reoccurring UTI’s and Lichen Sclerosis both which seem to have improved over the last two months. I use P.Happi twice daily and plan to continue to use.

I'm no longer dry down there, sex feels amazing, I don't experience irritation that leads to UTIs most of the time.

Why Should You Look After Your Intimate Microbiome?

Keeping your microbiome balanced and protected can help reduce the chances of infections and improve overall comfort and confidence

an unbalanced microbiome can cause infections such as utis, thrush and bacterial vaginosis

Your body's natural defence

When the intimate microbiome becomes unbalanced, harmful bacteria can take over, leading to discomfort & infections like UTIs, thrush, and BV

How long will it take to work?

During studies it was reported that the serum has immediate and long term effects

A Happi Microbiome = A Happi You

After six months of consistently using P.Happi our users are happy to report that their urine testing has come back completely clear!

Great for menopause

"I suffered recurrent UTI’s for nearly 30 years but everything I tried had no impact until I tried P.Happi. I had one UTI when I had a break from using it but six months on I have not had another. It also helps to keep the vulval area very moist especially through menopause and afterwards when vaginal atrophy can cause extreme dryness. I would not hesitate to recommend it."

FAQs

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.

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 of both it may be beneficial to apply them at different times, a few hours apart to allow them to work.

Yes, our Bits are safe for sensitive teeth. We use Nano-hydroxyapatite in our Fluoride-Free formula, a mineral that's been proven to strengthen and remineralize enamel and help fight sensitivity.

Read the nHAP Study here and read more information about it here.

We also recommend talking to your dentist about Nano-hydroxyapatite or when making any changes to your oral care routine.

P.Happi® cannot fix mechanical or functional related problems such as prolapse or voiding. The barrier function can support bacteria related problems stemming from the microbiome that may have been caused by something such as prolapse.

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 (60 applications). 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.
