Daré Bioscience Announces the Upcoming Launch of Flora Sync LF5™ Vaginal Probiotic Capsules

First Product Revenue Expected This Month, Opening New Commercial Chapter for Women's Health Innovator

Limited-Time Launch Offer: 30% Off + Free Shipping

SAN DIEGO, June 04, 2026 (GLOBE NEWSWIRE) -- Daré Bioscience, Inc. (NASDAQ:DARE), a purpose-driven health biotech company solely focused on closing the gap in women's health between promising science and real-world solutions, today announced the upcoming commercial launch of Flora Sync LF5™, a vaginal probiotic capsule formulated specifically to restore microbiome balance and support lasting vaginal comfort. The launch represents a milestone for Daré, as the company expects to generate its first direct consumer product revenue in June 2026, marking the company's transition from a pure development-stage biotech to a women's health company with a revenue-generating product.

Flora Sync LF5™ will be marketed under the brand family DARE to RESTORE™ and manufactured by Probiotical S.p.A., a global leader in probiotic development and manufacturing.

"Flora Sync LF5 was developed specifically for vaginal health, not gut health," said Sabrina Martucci Johnson, President and Chief Executive Officer of Daré Bioscience. "By delivering a vagina-specific probiotic strain directly to the vaginal environment, Flora Sync LF5 represents a targeted approach to supporting vaginal wellness. This upcoming launch marks an important milestone for Daré as it represents the company's first consumer health product launch. We continue to work to bring women other innovative, science-backed products they can access directly, without a prescription. We look forward to making Flora Sync LF5 available to women across the country and sharing our first commercial results with investors and our community."

ABOUT FLORA SYNC LF5™ (DARE TO RESTORE™)

Flora Sync LF5 is a targeted, non-hormonal probiotic vaginal capsule formulated with Limosilactobacillus fermentum LF5, a clinically studied probiotic strain originally isolated from the vaginal microbiome of healthy women with no reported history of yeast infections and backed by over 30 years of research.

Unlike most probiotics marketed for vaginal health, which rely on gut strains taken orally, Flora Sync LF5 delivers a vagina-specific probiotic strain directly to the vaginal environment, where imbalance occurs. This targeted approach is designed to support a healthy vaginal microbiome, natural moisture balance, and overall vaginal wellness at the source.

Flora Sync LF5 is manufactured by Probiotical S.p.A., a leader in probiotic science and manufacturing, under current Good Manufacturing Practices (cGMP) standards. Probiotical oversees every step of the process, from strain selection and scientific validation through manufacturing and quality control, helping ensure product quality, consistency, purity, and performance.

Upon launch, Flora Sync LF5 will be available without a prescription, for $49 per box (6 capsules), and offers a simple three-day routine designed for noticeable benefits. It is intended for women experiencing:

• Vaginal dryness leading to irritation or itching
• Unwanted odor or excess discharge
• Disruption following intimacy, hormonal shifts, or antibiotic use
• Routine changes such as travel, new products, or elevated stress

CLINICALLY STUDIED. BACKED BY OVER 30 YEARS OF PROBIOTIC RESEARCH.

Flora Sync LF5 is manufactured by Probiotical S.p.A., an Italian pioneer in probiotic science with roots in lactic acid bacteria research dating back nearly a century. From strain discovery and scientific validation to manufacturing under current Good Manufacturing Practices (cGMP) standards, Probiotical maintains oversight of the entire process to deliver a high quality, clinically studied probiotic designed specifically for vaginal health.

Flora Sync LF5 is supported by clinical research published in Frontiers in Microbiology (2024). In a single-blind, randomized controlled clinical trial of 100 women:

• 96% of women achieved vaginal microbiome balance within 3 days*
• 90% maintained a balanced vaginal microbiome at 2 weeks*

*Based on a single-blind, randomized controlled clinical trial of 100 women published in Frontiers in Microbiology (2024). Flora Sync LF5 is not intended to treat, cure, or prevent any disease or medical condition.

A COMMERCIAL MILESTONE IN A PIPELINE BUILT FOR WOMEN

The upcoming launch of Flora Sync LF5 marks the beginning of direct product revenue for Daré Bioscience, and arrives alongside significant momentum across the Company's broader pipeline.

On May 18, 2026, Daré announced the initiation of its Phase 2 clinical study of DARE-HPV, a novel pharmacologic treatment for persistent high-risk human papillomavirus (HPV) infection — the leading cause of cervical cancer cases in the U.S. — with no currently U.S. Food and Drug Administration (FDA)-approved treatments. The Phase 2 study is a randomized, placebo-controlled, double-blind trial in approximately 100 women. As previously announced, the study, as well as the broader DARE-HPV program, is funded by a $10 million contract funded by the Advanced Research Projects Agency for Health (ARPA-H). The Phase 2 study is expected to report topline data in 2027.

On May 12, 2026, Daré announced positive interim safety and efficacy results from its ongoing Phase 3 study of Ovaprene®, the Company's investigational monthly, hormone-free intravaginal contraceptive. The trial's independent Data Safety Monitoring Board (DSMB) conducted a second planned interim analysis focused on reviewing safety data from the study, and recommended the study continue without modification, consistent with its recommendation from the first interim analysis in July 2025. There currently are no FDA-approved, hormone-free, monthly intravaginal contraceptives.

Daré is also advancing DARE to PLAY™ Sildenafil Cream, a first-of-its-kind topical sildenafil cream for women, with dispensing through the DARE Health Hub targeted to commence this summer.

"We are building a company that generates revenue and advances science at the same time," Ms. Johnson continued. "Flora Sync LF5 will be the first chapter in Daré's consumer revenue story, and we intend to keep building from here, for women, and for our investors."
