Supplements

• Though the cause of psoriatic arthritis is not known, researchers believe it could stem from genetic and environmental causes, according to the Mayo Clinic. While there is no cure for psoriatic arthritis, there are numerous medications available to help manage symptoms. However, various alternative and natural remedies exist for those do not want to take or cannot tolerate medicine.
  
  Studies by the Mayo Clinic have shown that some vitamins and minerals can help quell symptoms. For example, eating certain vegetables that contain the carotenoid beta-cryptoxanthin will result in the body's production of a form of vitamin A, which helps suppress inflammation. Foods that contain a beta-cryptoxanthin include corn, papaya and watermelon. Zinc is another helpful mineral, as it reduces arthritis and aids in overall health. Zinc is found in foods such as liver, shrimp, yogurt and sesame seeds or via dietary supplements. Before beginning any regimen of vitamins or minerals it is important to speak to your doctor about the correct dosage.
