thiamine may increase effectiveness of antidepressants

A new study suggests that the nutritional supplement vitamin B1, also known as thiamine, can improve symptoms of depression when taken with an antidepressant. Edith Holsboer-Trachsler and colleagues presented the research from their randomized, double-blind, placebo-controlled study at a recent scientific meeting. In a 12-week study, about 50 adults (averaging 35 years of age) with major depression were prescribed a selective-serotonin reuptake inhibitor (SSRI) antidepressant. In addition, half received thiamine supplements while the other half were given placebos. Starting at six weeks, those receiving thiamine with their antidepressant showed more improvement in their depressive symptoms than those receiving the antidepressant alone.

Thiamine is an essential nutrient for humans. It is found in foods such as yeast, pork, cereal grains, and certain vegetables. Thiamine deficiency has been linked to irritability and symptoms of depression, while thiamine supplementation can improve mood and reduce feelings of stress. No side effects were reported in the study.
Holsboer-Trachsler and colleagues hope that thiamine supplementation may help patients adhere to their antidepressant regimens by decreasing the time it takes until their moods begin to lift.
