Some doctors have used vitamins B3 (niacin) and B6 and others for treatment of psychiatric disorders.

According to these doctors, there is compelling evidence to suggest nutrients involved in the synthesis or functioning of neurotransmitters dictate mental function. Hence certain nutritional deficiencies can significantly raise your risk of mental health problems. Nutrients that have a powerful influence on mental health include:

• Zinc

• Copper

• Selenium

• Niacin (B-3)

• Vitamin B-6

• Vitamin B-12

• Folates

• Vitamin D - having a level below 20 ng/mL can raise your risk of depression by 85 percent compared to having a level greater than 30 ng/ml

• S-adenosylmethionine (SAMe)

The idea is to normalize brain function through nutritional interventions.

Doctors also stress that one of the first steps in treating any mental health problem is to clean up your diet and address your gut health. Otherwise, you'll have virtually no chance of getting emotionally and mentally well.
