Vitamin D as workplace sensitizer

A recent ERJ correspondence letter highlights vitamin D (among other others) as sensitizer at the workplace.

Skin sensitisers are typically more hydrophobic than respiratory sensitisers. Both water-soluble and fat-soluble vitamins are used as additives in the food industry. Exposure at work to both of the above classes of vitamin compounds may occur, resulting in respiratory and skin sensitisation of workers during the manufacturing process.
