CAN VITAMIN D HELP PSORIASIS?
Vitamin D is a relatively popular ingredient in topical creams and ointments used to treat psoriasis, but can supplemental D also be effective? That’s the question asked by Michelle Ingram, PhD, at Massey University in New Zealand.
The study was intended to determine whether vitamin D supplements were more effective than placebo at easing psoriasis symptoms among 101 participants. The main findings of the study were inconclusive due to an unexpected increase in vitamin D levels in the placebo group, possibly due to sunlight. However, Ingram says, further analysis showed strong evidence of a link between higher levels of vitamin D and less severe psoriasis.
“Interestingly, this relationship was only found in about two- thirds of our participants,” says Ingram, “suggesting that vitamin D may be beneficial for some people with psoriasis, yet make no difference for others. Understanding the variability of response to psoriasis treatments in general is a long- term challenge and one that future research will hopefully be able to address.”
