 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.
