The multibillion-dollar supplement industry spews many dubious claims, but a new study suggests that some nutritional supplements, including omega-3 fatty acids and vitamin D, may boost the effectiveness of antidepressants. 【F1】If so. the supplements might help relieve symptoms for the millions of people who don't immediately respond to these drugs. Lead study author Jerome Sards of the University of Melbourne's ARCADIA Mental Health Research Group notes that a large percentage of people with depression do not fully respond during one or two trials of an antidepressant. By some estimates, two-thirds don't respond to the first antidepressant they try and a third fail to get better after several treatment attempts. 【F2】"The implications are that clinicians and the public can consider adding therapeutic doses of nutrients such as Vitamin D as a potential low-cost approach to reducing depression in people who are non-responsive to antidepressants," he says. Sarris and his colleagues speculate that the supplements may enhance the efficacy of antidepressants in various ways, perhaps directly by altering neuros-transmitter activity or indirectly by reducing inflammation known to contribute to depression. Leading nutritional psychiatry researcher Felice of Deakin University and the University of Melbourne explains that 【F3】conditions like depression can trigger a chain of physical concerns that certain supplements, when combined with accepted antidepressant therapies, could help ease. Doctors and scientists often come down hard on nutritional supplementation. 【F4】There is little to no scientific evidence backing many of the products crowding the shelves at health food stores and pushed by celebrity doctors. In fact, many come in mega-doses associated with serious side effects. And countless manufacturers produce these supplements, many with no standardized processes and varying degrees of quality control. Indeed, the supplement industry exists largely outside of any oversight by the Food and Drug Administration (FDA). In December last year, the FDA announced the formation of a new Office of Dietary Supplement Programs to help tighten regulation, but for now when it comes to supplements, consumers often don't know what they are getting. How does the evidence sit in light of the new study's findings? 【F5】"It is important to advise that a balanced whole-food diet is important for physical as well as mental health, and that supplements should not replace this," Sarris notes. "However, I believe a good diet in addition to select nutraceutical (营养食品 ) prescriptions can still be recommended in some cases, such as when people have inadequate responses to antidepressant medication."
