While vitamin D supplements show promise, more research is needed, and other nutrients like omega-3s and B vitamins also play roles in mood.
Vitamin B-12 and other B vitamins play a role in making brain chemicals that affect mood and other brain functions. Low levels of B-12 and other B vitamins and folate may be linked to depression.

Two forms of vitamin D are available in supplements: vitamin D3 and vitamin D2. Both can help correct vitamin D deficiency, but most doctors recommend D3 because it is slightly more active and therefore slightly more effective. Vitamin D3 is naturally produced by animals, including humans.
Scientific studies confirm a direct link between deficiencies in certain nutrients and symptoms of anxiety. Specifically, vitamin D and B vitamin deficiencies are strongly linked to the development of anxiety disorders.
