Transparency In Our Dietary Supplement Manufacturing Services

We believe open communication is crucial to forging a strong relationship with our nutraceutical and dietary supplement brand partners. We know a thing or two about transparency as Gemini was voted “Best in Class” for “Supplement Contract Manufacturing” by the Trust Transparency Center.

Our customer’s appreciation for this partnership has led to incredible growth and many shared successes.

Our Supplement Manufacturing Facilities

Gemini is unique in that our facilities are FDA registered and inspected to both 21 CFR Part 211 for pharmaceutical drug manufacturing and 21 CFR Part 111 for dietary supplement manufacturing. Maintaining facilities and operations at this level automatically builds in a higher quality threshold for even the simplest of products. You can have confidence in the supplements we manufacture in that they will be produced in our state-of-the-art facilities adhering to current Good Manufacturing Practices (cGMPs).

Gemini is routinely audited and cGMP certified through organizations such as UL, Intertek, and NSF. All of our buildings are environmentally controlled and equipped with best-in-class industrial HVAC systems to maintain ideal air quality. Sustaining clean air that is free from contamination is important to provide optimal conditions for both ingredient handling and manufacturing.

All of the ingredients used to manufacture your products are stored in our NSF cGMP temperature-controlled warehouse. We also test the ingredients on-site in our fully equipped ISO 17025 accredited laboratory. Having the expertise and testing equipment in-house allows us to offer quicker turnaround times on your products. Quality assurance finished product testing, analysis, potency, and contamination testing are also carried out here with the results published on your COA’s.

Dietary Supplement Manufacturing Equipment

Gemini uses the most advanced nutraceutical manufacturing and packaging equipment in the production of your supplements. Our expert staff uses precisely calibrated machinery at each stage of the manufacturing process. We ensure your items are made to exact specifications each and every time.

Every product is isolated to its own suite during the various manufacturing phases. Pharmacy operations, blending, encapsulation/compression, coating, and packaging are all segregated from any other product that is being produced. This prevents cross-contamination and allows you to achieve products that are free from allergens, sport-compliant, and non-GMO.

Our high-speed capsule fillers and tablet presses are capable to handle jobs of all sizes. We understand your demand can change fast and Gemini is well equipped to support you during those “rush” scenarios.

Supplement Companies We Work With

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, Health & Beauty, Government Organizations, Universities, Research Institutions, and New Emerging Markets.

Regardless of your class of trade all of our partners will appreciate the level of quality that is engineered into every product. Gemini is a proud member of the GRMA (Global Retailer Manufacturer Alliance) so you can expect that every product we produce is made with excellence. The GRMA 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 into 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 Retailers with the highest level of confidence that the dietary supplements are made in complete compliance with cGMPs.

Clean Label Manufacturing

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.

When reviewing your formula for clean-label manufacturing we assess if the common manufacturing agents can be substituted for natural alternatives. Using natural flow agents and fillers provides the consumer with an “other ingredients” section that is free from pharmaceutical excipients that are commonly used. Leveraging a long history of formulation expertise, Gemini has developed thousands of products that meet the clean-label criteria.

We also back all products we manufacture with comprehensive documentation and our proficiency 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 available through our Client Portal database.
