What is Lactobacillus crispatus?
Lactobacillus crispatus (L. crispatus) is a lactic acid producing, probiotic bacterium. This probiotic is highly beneficial to health and is naturally found within the healthy human microbiota. L. crispatus is most well recognised for its key contributions to female intimate health, with this bacterium being a dominant species within the vaginal and urogenital tract.
Health Benefits:
Supports Female Intimate Health
The presence of L. crispatus within the vaginal tract is believed to be key for female intimate health and has been repeatedly linked to reduced risk of infections such as bacterial vaginosis and yeast infections. This is largely through its anti-microbial action which helps to maintain a balanced and healthy microbiome. Beyond this, research suggests that vaginal L. crispatus dominance is associated with reduced rates of spontaneous pre-mature birth, suggesting that this bacterium may also be implicated in reproductive health.
Balances Microbiome
As a probiotic L. crispatus can help maintain a balanced and healthy microbiome, supporting healthy gut flora and inhibiting the growth of harmful pathogens. Through the production of lactic acid, L. crispatus increases pH acidity creating an environment unsuitable to many different pathogens, therefore protecting the body from their overgrowth and subsequent negative effects.
Boosts Immune Defence
L. crispatus may also have immune boosting effects through its protective actions against the growth of pathogens which helps to limit the risk of infection. Alongside this, L. crispatus is suggested to modulate immune cells (e.g. regulatory T-cells), increase anti-inflammatory cytokines and strengthen the mucusal barrier, all of which contribute to immunity and the maintenance of good health.
Typical Use:
L. crispatus is most commonly used in probiotic supplements and can often be found in formulations alongside other lactobacilli such as L. reuteri. Many people use such supplements maintain their intimate health and provide preventative support for recurrent infections.
