Your vagina has its very own microbiome. When it’s balanced, it is home to a diverse population of microbes that includes many Lactobacillus species, like L. crispatus, L. gasseri, L. iners, and L. jensenii. These bacteria produce lactic acid, creating the optimal pH for the vagina—a moderately acidic range of 3.8 to 4.5. This pH prevents the overgrowth of harmful microbes that can lead to various infections.
An imbalance of Lactobacillus species is largely associated with an imbalance in vaginal and urinary tract health. What’s often overlooked: Research shows that vitamin D may help balance the vaginal microbiome. Higher vitamin D levels may help maintain a greater abundance of Lactobacillus compared to lower levels, creating a healthy vaginal pH.
THE BEST VITAMIN D SUPPLEMENTS
Vitamin D is one of those nutrients that are hard to get enough of, especially if you’re protecting your skin from the sun (which is recommended). Spending lots of time outdoors and supplementing can help.
For a generous amount of vitamin D, Hum Nutrition offers a high-potency plant-based source—2,000 IU of vitamin D per capsule. And for those looking for vitamin D minus the capsule, three sprays of The Nue Co. Vitamin D Spray deliver 3,000 IU of vitamin D.*
Vaginal Cells, Vitamin D, and Lubrication
Similar to the tissue in our mouths, the vaginal wall is made of muscle covered in a mucus membrane, which contains epithelial cells. Vaginal epithelial cells are like a home to vaginal microbiota—they provide protection, nutritional support, and synergistic benefits. And they contribute to vaginal lubrication.
As these cells shed and replenish themselves, they help maintain a healthy vaginal environment. But when they’re not properly restored, it can lead to a vaginal imbalance and vaginal dryness. Research shows that vitamin D may help vaginal cells regenerate and improve lubrication. Vitamin D may rapidly increase the number of vaginal cells, potentially preventing or limiting vaginal atrophy, which is particularly prevalent in women during menopause and after.
Clean Lubes and Sex Serums
