Dietary Supplements

Gemini has decades of experience as a premier dietary supplement contract manufacturer of science-backed nutritional products. We specialize in developing high quality, unique formulations (including condition-specific) and line-extensions for customers in the United States and around the world. All products are made in our FDA, NSF International, and UL audited / inspected facilities in the United States.

Gemini is one of the few manufactures in the world to achieve both TGA (Australia) and Health Canada registration.

Gemini supports many types of organizations within the dietary supplement trade including Direct-to-Consumer, MLM, Chain Drug, Big Box Retailers, E-Commerce, Professional Health Networks, Managed Care, Export, Start-Up Venture’s, Governments, Universities, Research Institutions, and Emerging Markets.   


As a proud member of the GRMA you can expect that every product we produce is of the finest quality.  The GRMA (Global Retailer Manufacturer Alliance) working with NSF International has created the most comprehensive dietary supplement cGMP audit standard available. This standard uses a grading scale rather than a pass/fail approach used by other cGMP audits. It provides greater insight to the quality of the manufacturing organization and their level of cGMP compliance. A successful audit against this standard (NSF/ANSI 455-2) with a high grade provides Brand Owners and the Retailers with the highest level of confidence that the dietary supplements are made in complete compliance with cGMPs.

Gemini supports “Clean Label” initiatives as well, we design and produce products with Organic Certifications, Non-GMO certifications, products that are Pesticide free, Vegan & Vegetarian friendly, Allergen free, WADA compliant for sport, Kosher, Halal, and more to align with specific consumer preferences.

We back all products we manufacture with comprehensive documentation and our expertise in this area provides our customers with the foundation to navigate even the most stringent e-commerce, retailer, and export requirements. Gemini believes transparency is crucial for our customers to best succeed in the marketplace which is why we offer a Quality Partnership Program. These relationships provide our customers with direct access to key documentation regarding their products through our Client Portal database.
