Patricia Kongshavn received her Honors Degree in Natural Sciences as a Major Scholar at Cambridge University, and completed her doctorate in Immunology at McGill University after immigrating to Canada. She subsequently joined the Faculty of Medicine at McGill University and held appointments in the Departments of Physiology and Medicine, becoming Full Professor in 1986. Her research was funded by independent grants to her from the Medical Research Council of Canada, the National Cancer Institute of Canada and the National Institutes of Health in the United States.
In the mid-1970’s she began collaboration initiated by Dr Gustavo Bounous to research the influence of various dietary proteins on immune responsiveness. They published their first paper on this research in 1978 and continued their collaboration until 1989, during which period they co- authored 14 papers. This work led to the discovery of an undenatured whey protein concentrate that regulated glutathione levels and promoted immune enhancing activity. This led ultimately to the production of a high quality bioactive nutraceutical: Immunocal®.
