Results of a new double-blind, placebo-controlled human clinical trial found that daily supplementation with chromium picolinate significantly reduced some key symptoms of atypical depression. People who reported high levels of carbohydrate cravings experienced significant decrease in their carbohydrate cravings and depression in response to chromium picolinate. Also, there was no difference in side effects in patients treated with chromium picolinate compared to those treated with the placebo. Atypical depression is a common, but frequently undiagnosed, form of depression affecting up to 40 million Americans. The new evidence was presented today at a conference of the National Institutes of Mental Health (NIMH) New Clinical Drug Evaluation Unit (NCDEU) in Phoenix, Arizona.
Atypical depression is a major depressive disorder characterized by a distinct combination of symptoms that include mood swings, carbohydrate cravings, weight gain, rejection sensitivity and lethargy.
“This is the first indication thatchromium picolinate may play an important role in the reduction of carbohydrate cravings in people with atypical depression,” explains John Docherty, MD, President, Chief Executive Officerof Comprehensive NeuroScience, Inc. (CNS), principal investigator of the study. “It also may offer a new treatment option for atypical depressed patients with carbohydrate cravings who find it difficult to stay on current prescription medication because of the common side effects of sexual dysfunction and weight gain.”
The multi-center study of 113 patients found that daily supplementation with 600 mcg of chromium as chromium picolinate, significantly reduced carbohydrate cravings compared to placebo, and improved other symptoms such as mood swings, fatigue and weight gain perception. The results also show that people with the highest levels of carbohydrate cravings had the most significant reduction in depressive symptoms. “The study suggests that carbohydrate cravings may be a key and independent marker of atypical depression and might predict how patients will respond to chromium picolinate therapy,” added Docherty.
The research builds on beneficial effects of chromium picolinate reported in a recent pilot study published in the Journal of Biological Psychiatry. The study was conducted at the Duke University Medical Center Department of Psychiatry and Behavioral Sciences.
“We’ve seen remarkable improvements in depressed patients after supplementing with chromium picolinate,” says Malcolm McLeod, MD, a practicing psychiatrist, who collaborated on the Duke University study. “Chromium picolinate is a real breakthrough in providing safe and simple relief of atypical depression symptoms, many of which currently go untreated.”
