Some previous studies have suggested that it also increases serum 25-hydroxyvitamin D (25(OH)D) concentrations. On the other hand, most patients with chronic kidney disease (CKD) requiring dialysis are known to have insufficient vitamin D. We therefore conducted trials to assess how short NB-UVB courses could affect serum 25(OH)D concentrations in dermatological and haemodialysis patients in winter, when little UVB from the sun is available for vitamin D synthesis. In addition, we compared the effects of an NB-UVB course and oral vitamin D supplementation on serum 25(OH)D concentrations in healthy subjects.","brand":"Tampere University Press","offers":[{"title":"Default Title","offer_id":32423049265252,"sku":"9789514492617","price":57.95,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/suomalainen-test.myshopify.com\/products\/narrow-band-ultraviolet-b-exposures-improve-vitamin-d-balance","provider":"Suomalainen Test","version":"1.0","type":"link"}
