Probiotics

The human body hosts thousands of species of bacteria, yeasts, and other microorganisms, each adapted to specific environments such as the gut, skin and the vagina. These microbes typically coexist in a balanced state, playing essential roles in maintaining health. It is important to understand that the function of each microbe is closely linked to its preferred habitat. Bacteria that thrive in one area may not survive or function effectively in another. Placing bacteria in an unsuitable environment prevents them from thriving, meaning they cannot perform their intended role.

Choosing the right probiotics

Selecting the right live bacterial supplement for vaginal health can be overwhelming. With pharmacy shelves stocked with various options - each claiming different benefits, containing varying bacterial strains, and offering different storage requirements - it is crucial to understand what you actually need before making a choice.

Probiotic bacteria are named by their genus, species, and strain (e.g. Lactobacillus crispatus, LBV88). The strain identifier (letters and numbers after the species name) is crucial, as it signifies a well-researched, function-specific probiotics. When looking for vaginal probiotics look for scientific validation. Search for both the species and strain (e.g. Lactobacillus crispatus, LBV88) in published studies to verify their efficacy for your intended use.

Our Ultimate V and Ultimate UT probiotics contain a carefully formulated blend of strains isolated from the vaginal tract of healthy pregnant women. Extensive research identified the most beneficial species, chosen for their ability to support a balanced vaginal microbiota. Clinical and preclinical studies have demonstrated that this specific blend helps maintain vaginal health, provides relief from bacterial imbalances, and supports the vaginal microbiota in various individuals. 

Ultimate V and Ultimate UT vaginal probiotics contain:

  • Lactobacillus rhamnosus, LBV 96
  • Lactobacillus jensenii, LBV 116
  • Lactobacillus gasseri, LBV 150N
  • Lactobacillus crispatus, LBV 88

Lactobacillus rhamnosus

Lactobacillus rhamnosus is commonly found in the urinary tract of women with a healthy vaginal and urinary system. It is one of the most extensively researched Lactobacillus strains for its role in supporting urinary tract health and has been shown to help combat the yeast and bacteria associated with Urinary Tract Infections (UTIs) and Bacterial Vaginosis (BV).

Ultimate V and Ultimate UT vaginal probiotics contain Lactobacillus rhamnosus, LBV 96.

Lactobacillus jensenii

Lactobacillus jensenii is one of the four key beneficial bacteria naturally found in the lower reproductive tract of women with a healthy vaginal microbiome. It comprises approximately 25% of the vaginal microbiota in a well-balanced vaginal environment. 

This strain plays a crucial role in maintaining vaginal health by producing various bioactive compounds that support the vagina’s natural defences. Notably, L. jensenii, along with other Lactobacillus species, produces hydrogen peroxide, which has been linked to a lower risk of Bacterial Vaginosis (BV), Sexually Transmitted Infections (STIs) and Pelvic Inflammatory Disease (PID). 

Additionally, stable colonisation with L. jensenii is associated with a reduced risk of preterm birth, highlighting its importance in overall reproductive health. Ultimate V and Ultimate UT vaginal probiotics contain Lactobacillus jensenii, LBV 116.

Lactobacillus gasseri

Lactobacillus gasseri is one of the four key bacteria found in the vaginal microbiome of women with a healthy vaginal environment. This strain is a common and vital inhabitant of the vagina, contributing to vaginal health by producing lactic acid and hydrogen peroxide, both of which inhibit the growth of harmful microbes. 

Additionally, L. gasseri produces lactocillin, an antimicrobial compound that is particularly effective against the bacteria responsible for Urinary Tract Infections (UTIs), further supporting overall urogenital health. Ultimate V and Ultimate UT vaginal probiotics contain Lactobacillus gasseri, LBV 150N.

Lactobacillus crispatus 

Lactobacillus crispatus is the most abundant microbe in a healthy vagina and is the primary Lactobacillus species among the key bacteria that maintain vaginal health.This strain produces a variety of bioactive compounds, including lactic acid and hydrogen peroxide, which help inhibit the growth of harmful bacteria and yeast responsible for conditions such as Bacterial Vaginosis (BV), Vulvovaginal Candidiasis (VVC)(thrush) and Urinary Tract Infections (UTIs). 

While there are several strains of L. crispatus, not all are equally effective. It is essential to select the most beneficial vaginal-specific strain to ensure optimal protection and support for vaginal health. Ultimate V and Ultimate UT vaginal probiotics contain Lactobacillus crispatus, LBV 88.

By using probiotics that naturally originate from the vaginal environment, these products ensure effective colonisation, helping to promote overall urogenital health.

Colony Forming Units (CFUs)

The effectiveness of a probiotic depends not only on the strain but also on its viability. Colony Forming Units (CFUs) measure the number of viable bacteria capable of growing and multiplying. However, higher CFU counts do not always equate to better efficacy - what matters is ensuring the correct strains are present in an effective concentration.

A general guideline is that 1 billion CFUs per dose of a clinically studied strain is effective, though optimal amounts can vary. Another key factor is when CFUs are measured. Some manufacturers list the CFU count at the time of production, which does not account for bacterial loss over time.

Reliable products guarantee CFU counts at the end of shelf life, ensuring bacterial viability at the time 
of consumption. Pelvic Relief guarantees the activity of its Ultimate V and Ultimate UT probiotic strains for two years after production.

Bacterial viability 

Probiotics contain living microorganisms that must remain dormant until consumed. To achieve this, bacteria are cultured in a laboratory and freeze-dried before being packaged in capsules or sachets.

A common issue with probiotic supplements is improper packaging. Many are sold in jars or screw-top containers, which allow exposure to moisture and oxygen every time they are opened. This prematurely activates the bacteria without nutrients or a suitable environment, leading to bacterial death and reduced effectiveness. 

To maintain bacterial viability, Pelvic Relief probiotics are manufactured in a controlled, dry, nitrogen-filled environment to eliminate moisture and oxygen exposure and packaged in moisture-proof blister packs or sachets to prevent premature bacterial activation before consumption.

By choosing a supplement with scientifically validated strains, proper dosage, and protective packaging, you can ensure maximum benefits for your urogenital health.
