From the Guidelines
Lactobacillus acidophilus and Lactobacillus rhamnosus are the most effective probiotics for preventing vaginal yeast infections in individuals with diabetes, as they help maintain a healthy vaginal pH and compete with yeast for nutrients and adhesion sites. When selecting a probiotic supplement, look for products containing at least 1-10 billion CFUs of these strains, taken daily for prevention. Specific products like RepHresh Pro-B, Jarrow Formulas Fem-Dophilus, or Garden of Life Vaginal Care are good options 1.
For individuals with diabetes, maintaining good blood sugar control is equally important as probiotic use, since high glucose levels create an environment where yeast thrives 1. These Lactobacillus strains work by producing lactic acid that maintains vaginal pH around 3.8-4.5, creating an acidic environment that inhibits Candida growth. They also compete with yeast for nutrients and adhesion sites on vaginal walls, and some strains produce natural antifungal substances.
Some key points to consider when using probiotics to prevent vaginal yeast infections in individuals with diabetes include:
- Maintaining good blood sugar control to prevent yeast growth
- Using probiotic supplements containing Lactobacillus acidophilus and Lactobacillus rhamnosus
- Combining probiotic supplementation with dietary changes like limiting sugar and refined carbohydrates
- Wearing breathable cotton underwear to reduce moisture and prevent yeast growth
- Avoiding douching and taking antibiotics only when necessary, as they can disrupt vaginal flora 1.
It is essential to note that while probiotics can help prevent vaginal yeast infections, they should not be used as a replacement for medical treatment. If symptoms persist or worsen, individuals should consult their healthcare provider for proper diagnosis and treatment.
From the Research
Probiotics for Preventing Vaginal Yeast Infections in Diabetic Women
- The use of probiotics, particularly lactobacilli, has been investigated for the prevention of recurrent vulvovaginal candidiasis (VVC) 2.
- Studies have shown that lactobacilli can inhibit the growth of Candida albicans and/or its adherence on the vaginal epithelium 2, 3.
- Certain strains of lactobacilli, such as Lactobacillus acidophilus, Lactobacillus rhamnosus GR-1, and Lactobacillus fermentum RC-14, have been found to be effective in colonizing the vagina and preventing VVC 2.
- Oral intake of lactobacilli, such as Lactobacillus acidophilus GLA-14 and Lactobacillus rhamnosus HN001, in combination with lactoferrin, has been shown to lead to significant vaginal colonization and improvement of symptoms of abnormal vaginal microbiota 4.
- The combination of Lactobacillus rhamnosus and Lactobacillus acidophilus has been found to have antimicrobial activities against pathogens responsible for bacterial vaginosis and aerobic vaginitis 3.
Specific Probiotic Strains for Vaginal Health
- Lactobacillus acidophilus GLA-14 and Lactobacillus rhamnosus HN001 have been found to be effective in colonizing the vagina and improving symptoms of abnormal vaginal microbiota 4.
- Lactobacillus rhamnosus GR-1 and Lactobacillus fermentum RC-14 have been found to be effective in preventing VVC 2.
- The combination of Lactobacillus rhamnosus and Lactobacillus acidophilus has been found to have antimicrobial activities against pathogens responsible for bacterial vaginosis and aerobic vaginitis 3.
Role of Lactoferrin in Vaginal Health
- Lactoferrin has been found to have antimicrobial properties and can be used in combination with probiotics to support vaginal health 4, 5.
- The combination of lactoferrin and lactobacilli has been found to be effective in preventing vaginal infections and restoring the balance of vaginal microflora 5.
