Study author Ajay Goel, PhD, director of epigenetics and cancer prevention at Baylor University Medical Center, says synthetic options work well when taken as a one-hit fix, but that side effects, toxicity, and tolerance become concerns when the drugs are taken for chronic symptoms. Although curcumin has shown promise as an alternative to antidepressants for years, this is the first time researchers have been able to show the compound at work in humans, and its performance is promising. “From a clinical standpoint, a 2% lower efficacy makes no difference,” says Dr. Goel. “Curcumin has been proven safe, even at high doses.” Researchers are still at work trying to pinpoint exactly how curcumin balances depressive symptoms, but they have a few leads. Curcumin is a natural inhibitor of monoamine oxidase, an enzyme that at high levels, is linked to depression, and it also blocks the release of substances known as cytokines, which can throw off the delicate balance of your body’s stress reactions. Although doctors won’t be prescribing the compound to patients soon, anyone can reap the health benefits of curcumin capsules, which are available at most health food stores “It’s a very strong anti-inflammatory and antioxidant compound, and is great as an everyday health supplement,” says Dr. Goel. “People who do not have depressive symptoms can make this spice a part of their daily diet now.” More from Prevention: Curcumin Shown To Prevent Radiation Skin Damage
