Does low Vitamin D level correlates with low serotonin level. Is there any evidence. My level is 17 ng/ml. I am suffering from depression and anxiety quite long. Earlier also I have supplimented with Vit D3 (60000 IU/week for 8 week), but highest I could reach up to 31 ng/ml. Now again it below.
Then how to reach upto 50-60 ng/ml to become healthy?
