High Doses Of Vitamin D Help Soothe Inflamed Skin

Sunburn pain can be reduced with high doses of vitamin D taken one hour after sunburn, which significantly reduce skin redness, swelling, and inflammation.

Are you experiencing pain from sunburn? According to a recent study, reaching out for high doses of vitamin D soothes the inflamed skin.

High doses of vitamin D taken one hour after sunburn significantly reduce skin redness, swelling, and inflammation, according to double-blinded, placebo-controlled clinical trial out of Case Western Reserve University School of Medicine and University Hospitals Cleveland Medical Center.

‘Arginase-1 is an anti-inflammatory enzyme that enhances tissue repair after damage and helps in activating other anti-inflammatory proteins.’

In the study, 20 participants were randomized to receive a placebo pill or 50,000, 100,000, or 200,000 IU of vitamin D one hour after small UV lamp "sunburn" on their inner arm.

Researchers followed up with the participants 24, 48, 72 hours and 1 week after the experiment and collected skin biopsies for further testing. Participants who consumed the highest doses of vitamin D had long-lasting benefits, including less skin inflammation 48 hours after the burn. Participants with the highest blood levels of vitamin D also had less skin redness and a jump in gene activity related to skin barrier repair.

"We found benefits from vitamin D were dose-dependent," said senior author Kurt Lu. "We hypothesize that vitamin D helps promote protective barriers in the skin by rapidly reducing inflammation. What we did not expect was that at a certain dose, vitamin D not only was capable of suppressing inflammation, it was also activating skin repair genes."

The trial is the first to describe acute anti-inflammatory benefits from taking vitamin D.

According to the authors, despite widespread attention given to vitamin D deficiency, "there is a lack of evidence demonstrating that intervention with vitamin D is capable of resolving acute inflammation."

Key to Boosting Skin's Defence Against Sunburn Might be Held by Tomatoes and Grapes
Australian researchers will determine if extracts from tomatoes and grapes can bolster the skin's ability to fend off UV damage in a new study.

By measuring gene activity in the biopsies, the researchers also uncovered a potential mechanism behind how vitamin D aids skin repair.

The results suggest vitamin D increases skin levels of an anti-inflammatory enzyme, arginase-1. The enzyme enhances tissue repair after damage and helps activate other anti-inflammatory proteins.

With the recent trend that connects everyday items with sensors, the French have come up with a bikini attached device to detect sunscreen alert.

The study may have people flocking to vitamin supplement aisles, but Lu stresses that the trial tested very high doses of vitamin D that far exceed daily allowances.

The results are published in the Journal of Investigative Dermatology.
