A double-blind, randomized, placebo-controlled study is a type of clinical research to study if a new treatment works. It's like a test where some people get the real treatment and others get an inactive substance (like a sugar pill), and neither the participants nor the researchers know who is getting what. The study is set up this way to make sure that the results are impartial, accurate, and not influenced by any other factors. This type of study is considered the "gold standard" meaning that it is the best way to figure out if a treatment is effective or not.
Using this type of clinical research method, researchers were able to confirm that Lactobacillus rhamnosusGR-1 and Lactobacillus reuteriRC-14, the primary ingredients of Pro-Fem Vaginal Probiotics, are effective in restoring the normal vaginal pH with no side effects for their consumers. Upon evaluation after the study period, the vaginal microbiome of the participants who received the real treatment was restored at a greater magnitude than that of those who received the inactive substance.
Vaginal pH Balance: How Probiotics L. rhamnosus GR-1 and L. reuteri RC-14 Can Help
The vagina is normally colonized by various species of lactobacilli, which help to maintain an acidic environment with a pH of around 4.5. An imbalance in the vaginal microbiome, such as a decrease in lactobacilli, can lead to an increase in vaginal pH, making it more alkaline. An alkaline vagina can make it easier for harmful bacteria, such as yeast and other disease-causing agents, to grow and thrive, leading to conditions such as bacterial vaginosis and yeast infections. An alkaline vagina can also cause itching, burning, and other unpleasant symptoms, which can affect a woman's quality of life.
GR-1 and RC-14 are species of the probiotic lactobacillibacteria that have been proven to have potential benefits for women’s urogenital health. In a separate clinical study, it was found that GR-1 and RC-14 restore the normal balance of bacteria in the vagina and promote the growth of lactobacilli, which is instrumental in maintaining the ideal vaginal pH. The researchers classified these two strains as "non-chemotherapeutic," meaning that the treatment does not involve drugs or chemicals, but instead uses naturally occurring organisms to achieve the desired outcome.
Another randomized, placebo-controlled study further found that the intake of these two species is not only capable of keeping harmful bacteria and yeast from growing in the vagina, but it is also safe to take every day.
Achieving a Healthy Vaginal pH through Pro-Fem
GR-1 and RC-14 were discovered in the 1980s and patented by Chr. Hansen, the co-manufacturer of Pro-Fem and one of the most esteemed companies in the field of bioscience. For over 20 years, these strains have been tested and included in over 30 human clinical studies that support their therapeutic benefits. They have remained in widespread use ever since their discovery because of their safety and efficacy.
