Several natural treatments for psoriasis recommended by the National Psoriasis Foundation include vitamin D, omega-3 fatty acids, glucosamine and methylsulfonylmethane. Some of these supplements are ingredients of prescription medications for psoriasis, while others have been used as treatments for related conditions require further psoriasis-specific research.
Omega-3 fatty acids are recommended by the National Psoriasis Foundation as they actively fight inflammation in the body. Psoriasis is an inflammatory condition, and thus omega-3 fatty acids can have significant effects on the symptoms of psoriasis. In addition to their anti-inflammatory properties, omega-3 fatty acids have benefits for the immune system. Individuals with psoriasis often have lowered levels of omega-3 fatty acids, but further clinical evidence is required on the long term effects of omega-3 fatty acids on psoriasis.
Vitamin D is an active ingredient of such prescription medications for psoriasis, such as Dovonex and Vectical, adds the National Psoriasis Foundation. Psoriasis is thought to increase the growth rate of skin cells, while vitamin D combats this by slowing the growth rate. A 2011 report in the Science Translational Medicine Journal found vitamin D changes the way the body reacts to psoriasis-caused inflammation. Both chondroitin/glucosamine and methylsulfonylmethane are sulfur-containing compounds that can help with joint and soft tissue health. These supplements may have anti-inflammatory properties but further research is needed to determine their effectiveness in treating psoriasis.
