The Claim

In a mouse model of dihydrotestosterone (DHT)-induced polycystic ovary syndrome (PCOS), daily oral administration of the probiotic BL21 at a dose of 1 × 10⁹ colony-forming units (CFU) for 8 weeks was associated with reduced serum levels of pro-inflammatory markers (IL-6, TNF-α, and LPS) and increased levels of the anti-inflammatory cytokine IL-10, suggesting a potential anti-inflammatory effect of BL21 in the context of PCOS.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

In mice with a condition like PCOS, taking a specific probiotic every day for 8 weeks seemed to lower harmful inflammation and boost good anti-inflammatory signals in their blood.

In a mouse model of DHT-induced PCOS, 8 weeks of daily oral BL21 supplementation at 1 × 10⁹ CFU was associated with reduced serum levels of pro-inflammatory markers including IL-6, TNF-α, and LPS, and increased levels of anti-inflammatory IL-10, suggesting a potential anti-inflammatory effect of the probiotic in the context of PCOS.
