Psoriatic arthritis can occur in people with psoriasis, a condition characterized by red patches and silver scales on the skin. Most people develop psoriasis first and then psoriatic arthritis, though joint problems can begin before skin symptoms. Signs of psoriatic arthritis include swollen toes and fingers, foot pain and lower back pain. Always consult your doctor before taking supplements, and do not replace other forms of treatment with supplements.
Sulfur
Sulfur is a natural mineral that occurs naturally in some of the foods you eat, including fruits, vegetables, milk, eggs, Brussels sprouts and grains. This mineral may also be a beneficial supplement in the treatment of psoriasis. Sulfur baths or sulfur applied to your skin may relieve psoriasis, eczema, warts, and other skin conditions. You can consider increasing your dietary intake of sulfur or using baths or topical creams to help relieve symptoms.
Fish Oil
According to the University of Maryland Medical Center (UMMC), research has found that fish oil may help relieve redness, scaling and itching associated with psoriasis symptoms. Research has been mixed and more is required to establish a benefit. You should consult your doctor before taking this supplement or determining a good dose, because fish oil may increase your risk of bleeding.

Folic Acid
Folic acid may play a role in psoriatic arthritis and psoriasis treatment. This B vitamin can help decrease effects of a drug called methotrexate, sometimes used in the treatment of psoriasis. According to MedlinePlus, folic acid may also help reduce side effects of methotrexate treatment, such as vomiting and nausea. You can obtain this vitamin in a supplement or in dietary sources. Good choices include green leafy vegetables, beans, yeast, meat and fortified grain products.
Shark Cartilage
According to UMMC, shark cartilage has been shown to reduce symptoms of psoriasis. A dose of 80 to 100 g per day, two to four times, in the form of chondroitin sulfate, may be effective. You should not take shark cartilage if you have diabetes, since it may interact with diabetic medications. In addition, if you take calcium supplements, check with your doctor before taking shark cartilage, since it may disrupt the proper functioning of the supplements.
