Overview
Gemini Pharmaceuticals has produced tablets, capsules, and OTC pharmaceuticals from Commack, New York for over 30 years. The company produces 13 billion dosage units per year and packages over 150,000 bottles per shift. They report FDA registration, Health Canada site licensing, and TGA (Australia) listing; the company's NSF/ANSI 455-2 GMP certification was registry-confirmed on 2026-06-11 with three Commack facilities listed (a March 2026 check of NSF's legacy GMP directory had not found it — the listing lives in the 455-2 program directory). Gemini was the first manufacturer to earn RIBUS Certified Contract Manufacturer status for clean label products. They recently received approval for a $25 million expansion supported by Suffolk County IDA incentives. This expansion includes a new probiotic supplement facility at 81 Modular Avenue. Their 300,000 unit minimum order signals they serve mid-to-large brands, not startups. The ISO 17025 accredited in-house laboratory handles identity testing, potency analysis, and stability studies.
