Dr. Aly Cohen was recently featured in an Everyday Health article exploring whether vitamin D can play a role in managing psoriatic arthritis (PsA). With vitamin D deficiency linked to more severe psoriasis and PsA, Dr. Cohen explains why testing and supplementation may be important for patients.
She emphasizes the value of keeping vitamin D levels in the high-normal range to best support immune function and reduce disease activity—while cautioning that supplements should complement, not replace, standard medical treatments. Dr. Cohen also highlights the need for regular monitoring, since excessive vitamin D can be harmful.
