Bacterial Vaginosis (BV) and Yeast Infections: Nutritional and Lifestyle Factors Associated with Vaginal Health**

Bacterial vaginosis (BV) and yeast infections are common vaginal conditions caused by an imbalance in the vaginal microbiome. While medical treatment is sometimes required, nutrition and lifestyle factors play an important role in maintaining vaginal health, supporting the immune system, and reducing the risk of recurrent infections.

Role of Probiotics

The vagina normally contains beneficial bacteria, especially species of Lactobacillus, which help maintain a slightly acidic environment that prevents harmful bacteria and yeast from overgrowing. Consuming probiotic-rich foods such as yogurt with live cultures, kefir, and fermented foods can support this balance, especially after antibiotic use.*

Research suggests the following probiotic species and strains may be the most helpful for vaginal health:

• Lactobacillus rhamnosus GR-1, LBV 96

• Lactobacillus reuteri RC-14

• Lactobacillus gasseri LBV150N

• Lactobacillus jensenii LBV116

• Lactobacillus crispatus LBV88

• Lactobacillus acidophilus DDS-1, UALA-01

These strains are associated with improved vaginal microbial balance and reduced recurrence of BV and yeast infections, considering other diet and lifestyle factors are being accounted for. 

Importance of Limiting Sugar

High sugar intake increases the risk of yeast infections because yeast thrives on sugar. Excess sugar and refined carbohydrates can also weaken immune defenses. Reducing sugary drinks, sweets, and highly processed foods helps limit yeast overgrowth.

Fiber and Gut Health

Fiber supports healthy gut bacteria, which are closely connected to immune and vaginal health. Eating vegetables, fruits, whole grains, beans, and lentils helps maintain microbial balance and supports hormone regulation.*

Key Vitamins and Minerals

• Vitamin C supports immune function and helps maintain a healthy vaginal environment.

• Vitamin D deficiency has been linked to increased risk of BV and other vaginal infections.

• Zinc supports immune response and tissue repair.

• Glutathione and/or NAC

These nutrients can be obtained through fruits, vegetables, whole grains, nuts, seeds, fish, eggs, and dairy products.*  

Healthy Fats and Hydration

Healthy fats from olive oil, avocados, nuts, seeds, and fatty fish help reduce inflammation and support immune health. Adequate hydration supports normal vaginal secretions and overall body balance.

Lifestyle and Sexual Risk Factors for Recurrence

Certain lifestyle and sexual behaviors can increase the risk of recurring BV and yeast infections by disrupting the vaginal microbiome:

• Douching or internal cleansing, which removes protective bacteria

• Use of scented soaps, sprays, or feminine hygiene products

• New or multiple sexual partners, which can introduce new bacteria

• Inconsistent condom use, which may alter vaginal pH

• Tight, non-breathable clothing, which traps moisture and heat

• Frequent antibiotic use, which reduces beneficial bacteria

BV and yeast infections are not classified as sexually transmitted infections (STIs), but sexual activity can influence vaginal microbial balance.

Conclusion

Although nutrition and lifestyle changes cannot cure an active BV or yeast infection, they play a key role in preventing recurrence. A diet rich in probiotics, fiber, essential vitamins, and healthy fats—combined with healthy hygiene and sexual practices—can help maintain vaginal balance and support long-term reproductive health.
