Vitamin D may impact many aspects of human health, from proper functioning of the brain, down to the individual cells which make up the skin. A recent study found that vitamin D supplementation may decrease the severity of psoriasis, a chronic skin condition characterized by reddened, scaly skin.
The primary author of this study, Dr. Michelle Ingram, noted,
“This study was partly motivated by observations that some people with psoriasis report a reduction in symptoms during the summer months, when vitamin D production in the skin is usually at its highest. Vitamin D incorporated into a cream or ointment is also a relatively effective treatment for psoriasis, yet no one had looked into whether vitamin D supplementation might be of similar benefit.”
The study results were deemed inconclusive. The placebo group included in the study had an unexpected rise in vitamin D levels that was attributed to sun exposure. Despite lack of significant findings, the researchers noted an obvious trend of improvement in psoriasis symptoms as vitamin D levels increased.
This health condition is considered to be mysterious to researchers, doctors and patients alike. The cause and treatment are still to be determined, though it now seems as if vitamin D could be a potential therapeutic option. Future clinical trials are needed to confirm this theory.
