Do Vitamin D Supplements Help Psoriasis? We Asked a Dietitian
Medically reviewed by Allison Truong, M.D.
Vitamin D is something we often hear people with psoriasis ask about. Sure, there are topical prescription vitamin D creams (such as calcipotriene or calcitriol) that can help soothe inflammation, but what about taking supplements orally or adding more vitamin D to your diet? We asked our nutrition expert, Elizabeth DeRobertis, a New-York based registered dietitian about vitamin D and whether it is worth the hype for improving psoriasis symptoms.
Why do we keep hearing about vitamin D for psoriasis and psoriatic arthritis?
Vitamin D has been a buzz vitamin for a few years now. Vitamin D is a nutrient that we eat, and also a hormone that our bodies produce. It is required for the body to absorb and retain calcium, so it’s long been known to be essential for bone health. A few years ago, there were some studies that found it may help to reduce cancer-cell growth; and then, more recently, some studies on COVID-19 found that taking vitamin D may be beneficial to boost immunity to the virus.
