High Quality

For more than 40 years, we have been obsessed with quality at Nature Made®. From ingredient sourcing, to industry-leading manufacturing practices, to investment in new innovations, we believe it is our responsibility to lead in delivering quality products and a quality consumer experience.

This commitment to quality is critical because each year Nature Made produces more than 150 kinds of supplements, filling 120 million bottles with 11.5 billion tablets, capsules, softgels and gummies. It is a responsibility we embrace. We have often been part of pushing the supplement industry forward, and setting the standards that become the model for industry-wide regulation.

As part of a commitment to quality, Nature Made has a strict quality control process for responsible manufacturing. In addition, we invest millions of dollars in new technologies and follow rigorous production processes to ensure the superior quality we promise to our customers. This commitment to quality relies on two foundational elements: 


The path to quality products at Nature Made starts well before reaching our manufacturing centers. We work with the highest quality suppliers, and we ensure the quality levels of each new supplier via audits conducted by ourselves or experts we select. This ensures that our suppliers have clean, compliant facilities that follow Good Manufacturing Practices (GMP). Throughout the sourcing process we require our suppliers to show a Certificate of Analysis (COA) for the identity and quality of the ingredients they provide us. 

Our Process

From the moment ingredients reach our US-based manufacturing facilities, we are dedicated to some of the most demanding safety and quality standards in the industry. Every step of our product development process is focused on delivering the highest quality dietary supplements possible. When ingredients arrive, they are tested for identity, and we continue verification at every stage of the manufacturing process to ensure we meet or exceed industry standards -- using techniques like infrared scanning, high performance liquid chromatography and mass spectrophotometry. As ingredients are weighed, blended, compressed, encapsulated, inspected and finally packaged as different vitamin products, we test or inspect appropriately to ensure quality.
