A Response to Newsweek’s ‘Why Antidepressants Are No Better than Placebos’

by

In January 2010, Newsweek published a piece by Sharon Begley exploring the efficacy of antidepressants. The following letter was sent to its author.

To Sr. Editor Sharon Begley

 

Thank you for your recent article questioning the benefits of antidepressant drugs. The growing documentation of new antidepressant side effects further supports the need for such inquiry. The most important question, though, is whether more effective and safer alternatives are available.

 

Your article discusses the benefits of psychotherapy, but several other methods have proven beneficial as well, notably diet, exercise, and light. (See my book, The Mood Cure.) For example, over the past twenty years, in a number of studies, the diets of formerly depressed subjects have have been depleted of the amino acid tryptophan. Tryptophan is the essential nutrient required for the production of serotonin. A prompt return of depression has been the result, in almost every study. Additional well-established serotonin deficiency symptoms, such as OCD and bulimia, have also been repeatedly elicited in these tryptophan-depletion studies.

 

Even more hopeful studies have confirmed that increasing tryptophan intake raises serotonin levels. Because of this, hundreds of U.S. clinicians are now successfully recommending one of two forms of supplemental tryptophan. Both forms, 5-hydroxytryptophan (5HTP) and l-tryptophan, are readily available in health stores and online, and take effect very quickly. Our clinic has been recommending these and similar brain-targeted nutrients successfully for thirteen years–as our primary depression therapy for adults and children. We add an antidepressant diet plus light, exercise, psychotherapy, and, rarely, SSRIs, as needed.

 

Jim Carrey is currently the most famous and vocal advocate of this safe and effective approach, but I expect we’ll be hearing much more about it.
