We are family-owned and operated.

Founded in 1987, we are one of the most credentialed dietary supplement manufacturers in the United States. Our vision is to improve the quality of life through safe and effective wellness products. We make progress toward our vision by executing the four rights: product, price, quantity, and time.

We’re located in Southern California and operate two facilities that house our manufacturing, packaging, laboratories, and warehouses. Since 2001, our facilities have been audited, inspected, and/or certified by numerous quality management systems organizations including: FDA cGMP, UL cGMP, NSF cGMP, ISO 9001:2015, USDA NOP, CCOF Organic and IFANCA Halal regulations.

We can manufacture and package dietary supplement capsules, tablets, and powder drink mixes. And we can test those products in our four state-of-the-art analytical laboratories.

We love expanding our family by working with like-minded supplement companies who genuinely believe in improving the quality of health through our wellness products. Call us today at 1-866-NHKLABS.
