Heard alot about vitamin D lately? Well its for good reason! Yet another study has shown benefit of having appropraite vitamin D levels, this time in depression. Depression is a currently estimated to be the number one cause of disability worldwide by the WHO, and levels are expecred to rise! Vitamin D is typically made by our bodies through sun exposure, so with winter approaching now is the time to get your levels checked. Could "Seasonal Affective Disorder", a form of depression suffered by some in the winter months, be related to low vitamin D levels in the winter months? More research will be need to find out, but it seems plausible. Besides depression, appropriate vitamin D levels are associated with decreased flu risk, weight loss, preventing several cancers and increasing muscle mass! I typically recommend 2000 IU of vitamin D3 in the winter months but you should have your levels tested and monitored to keep them in a healthy range of 50-80 ng/mL.
