Company History:
In 1932, Dr. Edward Howell founded National Enzyme Company (NEC) to produce a general digestive enzyme-based formula, Genuine N-Zime #1. In that year, NEC was incorporated in the state of Illinois and was founded to meet the growing demands for his unique enzyme products.

In 1977, the current owner, Anthony Collier, began working for National Enzyme Company as the office manager; in 1979 he purchased the company. After relocating to Forsyth, MO, NEC began experiencing growth in the private label sector. With the help of research and product development, marketing efforts, a technically trained sales staff, and the ability to secure exclusive enzymes directly from the grower, NEC has strengthened its position as a manufacturer and marketer. As a result of the company’s focus on custom formulation, NEC has grown to become the leader in the enzyme supplement industry.

NEC is GMP certified by NSF International. NEC is also an approved Occupational Safety and Health Administration (OSHA) Voluntary Protection Program (VPP) site. VPP participants establish and maintain excellent safety and health programs in their workplaces and are recognized by OSHA as models for their industries. NEC is the supplier of choice for enzymes in dietary supplements. We provide exclusive and proprietary blends of microbial and plant-based enzymes to manufacturers, marketers, and distributors worldwide.

National Enzyme Company holds memberships to the following: AHPA, NNFA, ETA, ANA, NSF, and TGA.
