Mood disorders are a group of psychological conditions in which a disturbance in a person’s mood is considered to be the main underlying feature. Specifically, loss of interest or pleasure in normally enjoyable activities and decreased functional capacity are underlying presentations of depressive disorder across the entire depressive continuum.
In addition to quality-of-life and medical costs, lost productivity is estimated to cost U.S. employers over $44 billion annually, 81% due to poorer on-the-job performance,1 or “presenteeism” (present but less effective).2
To complicate the picture, more than half of the people with depression also have anxiety as a simultaneous condition.3 Anxiety and depressive disorders comprise major mental health concerns in U.S. adults, with 28.8% and 20.8%, respectively, experiencing these disorders during their lifetime.4
Mood disorders are diagnosed conventionally by a thorough physical and psychological evaluation.
Conventional treatment of mood disorders is based primarily on pharmacotherapy or psychotherapy, or (ideally6) a combination of both. Focusing on a deregulation of neurotransmitter signaling as the major cause of depression has been the foundation for the use of antidepressant drugs for the last 60 years.7 Some studies have found that the benefits of antidepressants, while helpful for a set of patients with more severe symptoms, may be minimal or nonexistent for patients with milder or more moderate symptoms.8,9 In addition, medication side effects are frequent, with almost 40% reporting one or more side effects from the commonly prescribed serotonergic medications; sexual dysfunction, sleepiness, and weight gain are the top three complaints.10
Given concerns related to such pharmaceutical side effects, many patients have sought alternatives to pharmacological treatments. [Freeman MP, Mischoulon D, Tedeschini E, et al.

The etiology of mood disorders is multifaceted and includes biological, psychosocial, environmental, and lifestyle factors. Nutritional status is one of the key factors in proper brain development and normal cognitive function.11 Diet quality has been associated with common mental disorders, including depression and anxiety,12-16 and certain nutrients have been found to be particularly important. For instance:
Comprehensive nutritional testing can ensure a solid foundation, identifying nutrients needed to support critical enzyme function in neurotransmitter pathways that may support optimal mood. The level of functional performance of these critical enzymes can be reliably estimated by assessing the “upstream” building blocks and “downstream”metabolites in these relevant pathways:
Identifying and supplementing a patient’s targeted needs helps to personalize treatments that may alleviate symptoms associated with underlying nutritional imbalance.
Our comprehensive NutrEval® profile provides an insightful tool for clinicians managing the care of patients who are seeking individualized nutritional support for optimizing mood.
