The Standard Process and Lee brands

About Royal Lee Organics® by Standard Process®

Our mission is to continue the legacy of Dr. Royal Lee by helping people live better, healthier lives.

Long History. Unwavering Purpose.

In 1941, our founder Dr. Royal Lee organized the Lee Foundation for Nutritional Research. The goal of the foundation was to address nutritional challenges and educate people about the importance of proper nutrition. Under the auspices of the foundation, Dr. Lee published countless works of research on the topic of whole food nutrition and its positive effect on health and wellbeing.

The results of his research were reflected in his Therapeutic Foods Company, which eventually became known as Standard Process, the visionary leader in whole food nutrient solutions.

As a leading critic of commercially produced flour, Dr. Lee developed a home flour mill as a way for average Americans to derive the optimal nutritional benefit in whole wheat flour. He marketed and sold this mill under the Lee Engineering brand.

In the late 1980s, Standard Process sold Lee Engineering to Electro-Mechano. In 2014, Standard Process purchased Lee Engineering back from Electro-Mechano. We have since redesigned and upgraded the mill to create an even higher quality product. We now offer the Lee Household Flour Mill, organic whole grains and other nutrition-focused products under the Standard Process subsidiary brand Royal Lee Organics.

About Lee Engineering

Lee Engineering, LLC is continuing the legacy of Dr. Royal Lee. Founded in 1927, Lee Engineering designs and manufactures laboratory lattice systems, motorized household appliances, momentary foot switches and centrifugally controlled governed motors. Our redesign of the 1949 “Attrition-type flour mill” combines Dr. Lee’s centrifugal governor and stationary stone mill with a modern variable torque motor.

About Standard Process®

For more than 85 years, Standard Process has been the visionary leader in whole food nutrient solutions. The company applies a systems-thinking approach to holistic nutrition that empowers health care professionals to transform lives. Dedicated to the field of nutritional supplements, Standard Process is guided by the whole food philosophy of its founder, Dr. Royal Lee. Dr. Lee’s goal was to provide nutrients as they are found in nature, where he believed their natural potency and efficacy would be realized.

Today, Standard Process proudly carries on Dr. Lee’s legacy and regularly grows more than 60 percent of the raw plant ingredients found in its products on its certified organic farm in Palmyra, Wisconsin. These crops include alfalfa, barley grass, beets, Brussels sprouts, buckwheat, kale, kidney beans, oats, pea vine, and Spanish black radish. Using its own organic crops gives the company control over the quality of those ingredients, from seed to supplement.

Utilizing state-of-the-art manufacturing processes, Standard Process employs high quality control standards and strictly adheres to the U.S. Food and Drug Administration's good manufacturing practices. Many of these processes are also certified organic, ensuring that ingredients remain organic from seed to supplement.

When seasonally available, Royal Lee Organics offers organic grains and other provisions from the Standard Process certified-organic farm.

Standard Process offers nutritional supplements and Veterinary Formulas, and is the exclusive U.S. Distributor of MediHerb® herbal supplements. Committed to transforming people’s lives for the better, the company offers products exclusively through qualified health care professionals.
