Established in the 1950s, Natural Factors is one of the largest manufacturers of nutritional supplements in North America and is privately owned. They are located in Monroe, WA and their Canadian office is located in Coquitlam, BC, Canada.

Their farm, Natural Factors Farm is located South of Armstrong, BC, Canada. Natural Factors Farm is certified organic farmland and is the location where high quality raw materials and ingredients are sourced from to produce products from Natural Factors.

Natural Factors Farm is located on an extremely fertile land that has special lime stratification. This is essential to neutralizing the pH of the soil. Seeds are carefully selected to be non-hybrid and non-GMO. Their manufacturing facilities include capabilities for softgel and two-piece hard-shell encapsulations, as well as tableting.

Natural Factors is unique from most manufacturers because they own their own organic farms, extraction/encapsulation/production facilities and their own research centers and labs. Products by Natural Factors undergo rigorous testing for radiation, non-GMO and mass spectrometry testing (this is a method in which definitive analysis of natural products can be done).

Natural Factors is also an environmentally conscious manufacturer. They have established ways to reduce waste and improve energy use and continue to find ways towards zero waste.
