Saw Palmetto for Depression
Depression is among the leading causes of disability worldwide, according to the World Health Organization, and in the United States, women are two times more likely to develop depressive disorder than men. Treatments for depression typically include medications and psychotherapy, yet it may be possible to curve the severity of depression through herbal remedies. Saw palmetto is a popular herb for prostate health, and proponents suggest it may have benefits for depression symptoms. However, the scientific community offers no solid data regarding this use. As with any supplement, speak with your physician before taking saw palmetto.

SAW PALMETTO CONSTITUENTS
The active compounds in saw palmetto include flavonoids, fatty acids, plant sterols and polysaccharides. It is believed polysaccharides may help support the immune system and reduce inflammation. Plant sterols and flavonoids are thought to be the primary medicinal compounds in saw palmetto.
EFFECTS ON DEPRESSION
As of 2011, there were no scientific studies regarding the effectiveness of saw palmetto for depression. However, preliminary studies suggest the antioxidant qualities in saw palmetto flavonoids may help treat depression. Antioxidants are believed to help protect the mind from cognitive decline and other damage done by free radicals. Because saw palmetto features a high concentration of flavonoids, or plant antioxidants, this herb may help prevent and reduce depression symptoms caused by oxidation, or free radical damage.
RECOMMENDED DAILY INTAKE
Saw palmetto may be taken in capsule extract form. The recommended dose for prostate patients is 160 mg twice daily. The University of Maryland Medical Center suggests using an extract with 85 to 95 percent fatty acids and plant sterols. While saw palmetto may be consumed as a tea, its primary active ingredients are not water-soluble, and therefore cannot transfer from the herb to the tea.
SAFETY CONSIDERATIONS
Even though saw palmetto is considered generally safe for healthy adults, discuss the use of this herb with your doctor before starting a supplementation program. Common side effects include minor headaches and mild upset stomach. If you are taking antidepressants or any other medications, do not use saw palmetto without the direct consent of your doctor.
