Fish oil: Does it help?

Fish oil is known to be good for health. It contains omega-3 fats, which can help reduce inflammation. Since psoriasis is a skin condition caused by inflammation, many people think fish oil might help treat it.

A new study looked at whether fish oil helps people with psoriasis. The researchers checked 18 trials with 927 people. They found that fish oil alone didn’t make a big difference in the size or severity of psoriasis. But when fish oil was used with other treatments, it helped. People who took fish oil along with their regular treatments had less psoriasis and less itching. It also helped lower the risk of heart disease in people with psoriasis.

Conclusion
Fish oil might help people with psoriasis, but only if it's used with other treatments. It doesn’t seem to work on its own.
