The Marion Gluck Clinic

What The Marion Gluck Clinic does

The Marion Gluck Clinic, operating under the legal entity Gluck International Limited (wholly owned by holding company Gluck Health), is a UK-based private hormone clinic founded in 2008 and headquartered in London. It provides personalised Bioidentical Hormone Replacement Therapy (BHRT) using hormones structurally identical to those naturally produced by the body and derived from Mexican yams, compounded by its wholly owned subsidiary Specialist Pharmacy in individualised dosages (creams, lozenges, capsules). The clinic treats perimenopause, menopause, PCOS, PMDD, thyroid dysfunction, and andropause, and has cumulatively served more than 14,000 patients since inception.

Since pivoting to an online-only telehealth model in early 2020, the clinic delivers care via video and telephone consultations with 24/7 online booking, supported by blood draws at third-party venues (including Superdrug) and laboratory partners (The Doctors Laboratory, Genova Diagnostics, Regenerus Laboratories, Nordic Laboratories). It earns revenue from initial specialist consultations (professional services), a repeat-prescription service that functions as recurring revenue for patients within 12 months of their last consultation, blood-test fees, and medication purchases processed through Specialist Pharmacy. Adjacent revenue lines include a doctor-led Weight Management Programme using GLP-1 medications, a Functional Medicine Clinic, and an online BHRT training programme delivered through the Marion Gluck Training Academy (founded 2016).

The go-to-market is direct-to-consumer, content-led, and digitally distributed across the UK, with significant earned-media coverage in The Times, Daily Mail, Vogue, and Stylist and a monthly newsletter. The clinical operation is led by Founder & Medical Director Dr Marion Gluck, with Clinical Lead Dr Ghazala Aziz-Scott and a team of at least ten hormone specialists. The clinic is CQC-registered under the Health and Social Care Act 2008 and reports patient outcomes including a 52% improvement in overall quality of life and substantial reductions in night sweats, sleep difficulty, fatigue, and irritability across its treated cohort.
