Depression is a condition that can present in a variety of ways with varying degrees of severity. Some individuals can have a very mild case, that may only occur in the winter. While others may be debilitated most days of the week with feelings and symptoms severe enough to prompt life ending thoughts.
However, severe or not, depression is a serious matter. Any person who feels they may be suffering from depression or if a loved one is showing signs, please seek help from a professional. There is a plethora of information available in the news, library, and internet but this cannot replace the advice and expertise of a healthcare provider.
A recent review from Australia was published in the journal Nutrition and Dietetics. The review focused on natural treatments for depression including St. John's Wort, Fish oils, and B Vitamins.
The primary reviewers concluded that most information supports use of omega 3 fatty acids such as those found in fish oils, for the treatment and relief of depression and depressive symtpoms. The two main fatty acids in fish oil are EPA and DHA, both of which also help to lower inflammation in the body. Omega 3 fatty acids were studied under a variety of designs including clinical trials, prospective, and epidemiological studies and found to be effective for treating mild to moderate depression. They are safe to use, even in pregnancy, and have very few side effects.
Both St. John's Wort and tryptophan were found to be effective at treating depression, even though some studies found conflicting evidence. Tryptophan is an amino acid precursor to neurotransmitters in the brain that are often low or depleted in person's with depression. St. John's Wort has been shown to increase levels of neurotransmitters perhaps by inhibiting their breakdown.
The reviewers did not find as much promising evidence for folate, Vitamin B6 or Vitamin B12. Too many studies were conflicting and the benefit was not substantial in some of the studies that found some positive effect.
In conclusion the reviewers state "The role of balanced nutrition in mental health should be recognized."
