How it works?

Created by hormone health experts, pH Hero® is a specialist formula to prevent signs of Urinary Tract Infections (UTIs), Bacterial Vaginosis (BV), Vaginal Atrophy (VA) and yeast infections

pH Hero® is a unique formula of probiotics, prebiotics and botanicals to create and maintain a naturally balanced and healthy vaginal flora. There is an intimate relationship between the gut and vagina, known as the ‘gut-vagina axis’, a term referring to the connection between the gut microbiome and the vaginal microbiome. Since the vagina has its own unique microbiome, pH Hero® is uniquely formulated to help it thrive and maintain a perfect pH balance and protect against infections, dryness and discomfort.

Supports a healthy vaginal microbiome and balances the vagina pH, protecting against recurring infections

pH Hero® includes 5 bacterial strains that are natural to the health of the vagina and urinary tract. The bacterial strains have been clinically studied for the effects they have on epithelial barriers (cells on the inside and outside of the surfaces of our body) and the growth of unhealthy bacteria in the vagina, bladder and gut. 

The Lactobacilli species in particular have been shown to support the acidity of the bladder as well as the urinary tract through lactic acid production, and in turn, can help in rebalancing the vaginal microbiome.1-3

Lactobacillus acidophilus: Repopulating our colon with the Lactobacilli species supports creating a healthy environment for the female genitals. Lactobacillus acidophilus is one of the most researched strains of bacteria studied to support and maintain a healthy vaginal microbiome, and research shows a healthy lactobacilli-dominated flora can help in preventing sexually transmitted diseases and maintaining the quality of life of women.  

pH Hero® includes Lactobacillus rhamnosus and Lactobacillus reuteri strains, which provide the two most effective strains for the prevention of UTI.  Lactobacillus rhamnosus, which is commonly found in a healthy vaginal microbiome, has been clinically shown to help maintain a healthy pH. Lactobacillus reuteri has proven to be effective in maintaining a healthy vaginal pH when combined with other Lactobacilli strains. L. reuteri can help crowd out unhealthy organisms and strengthen the vagina’s natural defences against organisms like ‘Candida Albicans’, a well-known yeast commonly implicated in vaginal yeast infections, including vaginal thrush.6-8,10-12

Lactobacillus plantarum helps to balance and reset vaginal pH and restores the diversity of microflora. L. plantarum supports the gut microbiome but is also able to reach the vaginal epithelial cells and can play a significant role in helping prevent the occurrence of Bacterial Vaginosis (BV), a type of infection caused by an overgrowth of yeast. L. plantarum has been shown to have strong anti-microbial activity against bacteria including E.coli which is responsible for the development of UTIs.10-13

Lactobacillus crispatus is a probiotic strain proven to reach the vagina and has been extensively studied for how it contributes to a healthy vaginal microflora, and helps prevent the overgrowth of yeast and other unwanted bacterial infections.

Vaginal dryness and discomfort

Sea buckthorn has been extensively studied for its role in supporting the body's mucosal function and helping provide a protective barrier in the vagina. Research shows it may help protect against vaginal dryness and maintain healthy skin from within. Studies show Sea Buckthorn can improve vaginal health within 3 months, including significantly improving the integrity of the vaginal epithelium (the inner lining of the vagina), thus reducing signs of vaginal atrophy.24-27

Supports a healthy urinary tract

pH Hero® provides Cranberry Extract at the optimal dose of 4g per serving. Cranberries have a well-established role in the prevention of urinary tract infections by supporting the body’s defences against external agents through their powerful antioxidants. Antioxidants help protect the cells from oxidative damage and support a healthy urinary tract. Cranberries also support our overall physical wellbeing.

Cranberries contain proanthocyanidins (PACs) and research shows that the consumption of cranberries helps prevent the adhesion of particularly harmful bacterial strains to the urothelial cells of the bladder. This, in turn, combats the early stages of UTI infections.30-32

Parsley and Nettle both support urinary tract function and normal urinary flow, including the excretion function of the kidneys. This ensures the body is efficiently eliminating toxins that can otherwise contribute to infections.

Regulates hormonal balance

The vaginal pH and microbiome change with the hormonal changes women go through, during the menstrual cycle, through pregnancy and through menopause. Vitamin B6 is an essential vitamin to regulate hormonal balance, and pH Hero® includes 2.8mg (200% NRV) of Vitamin B6 to support and regulate hormone activity.

Immune and gut health support

Immune support

  • Supporting the immune system is an important aspect of supporting gut and vaginal health.
  • pH Hero® provides a high potency of Cranberry Extract at the optimal dose of 4g per serving, rich in nutrients including Vitamin C and plant polyphenols. Vitamin C provides immune support and offers protection against oxidative stress, which in turn helps build resilience against the development of further infections, as well as supporting a swift recovery when feeling under the weather. Nettle and Vitamin B6 also provide valuable support for the immune system.

Gut health support

  • Supporting the gut flora plays an important part in supporting the immune system - at least 70% of the body’s immune system is fuelled by our gut. pH Hero® provides the synergistic combination of inulin, a prebiotic fibre and 5 Probiotic bacterial strains. Inulin provides an important type of gut-friendly fibre found in many plants and which helps other gut-friendly bacteria grow.

How your gut and vagina are linked

The gut and vagina are connected by a number of mechanisms, including nerve pathways and hormones. If the gut microbiome is not healthy, it can have a ripple effect on the vaginal microbiome, and disrupt the delicate balance of the vaginal microbiome. A high-fibre diet full of probiotics and prebiotic foods can really help support your gut flora and vaginal flora. Learn more.
