Vitamin D Supports Mood

Vitamin D receptors are found throughout your brain so it is not surprising to find that new research demonstrates that adequate vitamin D¹ supports mood.

Researchers at Georgia State University used data from the National Health and Nutrition Examination Survey to analyze serum vitamin D and depression in 7970 non-institutionalized U.S. residents, aged 15-39.

“The mechanism through which vitamin D plays a role in mental health is not clearly understood,” said the researchers. “Active vitamin D enhances glutathione metabolism in neurons, therefore, promotes antioxidant activities.”

A lack of vitamin D is one reason for a poor mood as the winter months roll along. Supplemental intake of 1000 IU to 5000 IU is a general recommendation. Higher intake of vitamin D may be needed but should be monitored with blood tests. The target range for optimal vitamin D is 50–80 ng/ml (125–200 nmol/L).  A score of 30 ng/ml is the minimal “normal” and is not adequate for optimal health.
