Your Brand-Our Commitment


Essential Pharmaceutical Corp. provides not only an extensive line of products, but also the professional service by experienced staff to ensure buyer's needs are met. Our plant is organized for producing long and short runs. So minimum order quantities are tailored to the client's sales. Both small and large companies can purchase private label products of the quantities to their needs. This lowers inventories, creates faster turn-arounds, and leaves no outdated products, thus generating increased profits for the clients.

All of our products are equal to the national brands in formulation, packaging and quality.  We continuously strive to maintain our enduring reputation by delivering exceptional services, reliability, good working ethics and most importantly, high-quality dietary supplements.
