The Kirkland Signature brand was launched in 1995 by Costco Wholesale Corporation, named after the city of Kirkland, Washington, where the company's headquarters were located at the time. The brand was created to provide high-quality alternatives to national brands at lower prices. While Costco does not manufacture the products themselves, they partner with leading global manufacturers to produce items under the Kirkland Signature label. For their vitamin and supplement line, production is primarily based in the United States, utilizing various specialized contract manufacturers to meet strict safety and quality standards.

Costco Wholesale Corporation remains the ultimate owner and distributor of Kirkland Signature. As one of the world's largest retailers, Costco operates a membership-only warehouse model that emphasizes scale and efficiency. This ownership structure allows the brand to maintain consistent quality across a vast array of product categories, from groceries and household goods to health supplements like CoQ10.
