Functional Diagnostic Nutrition



Do you have clients who are eating a healthy diet, yet are experiencing pain throughout their body? Or, clients who are struggling with Candida yeast overgrowth, despite a grain-free/sugar-free diet and several rounds of anti-fungal herbs? What about clients who are experiencing mineral deficiencies, bone loss, inflamed joints and muscles, frequent urinary tract infections, or kidney stones? These can all be symptoms of excessive amounts of oxalates in the body.

Oxalates are naturally occurring substances found in plants and produced inside the human body. Unfortunately, oxalates are anti-nutrients which interfere with the absorption of minerals and can form sharp, knife-like crystals in the body which get lodged in tissues and organs, causing pain and inflammation. While the body can handle low to moderate amounts of oxalates, problems develop when there are excessively high levels of oxalates, which can occur due to a number of factors.
