The purpose of the study is to determine the importance of the UV intensity and the UVB dose on the Vitamin D response after UVB.
The work is addressing vitamin D production after UVB exposure and explore the importance of UVB dose and UV intensity. Four different UVB doses and four different UV intensities are used to explore these relationships.
Many assumptions have been made concerning the vitamin D production after UVB exposure but only few studies exist.

Studies have shown that patients with chronic kidney disease in hemodialysis have a low vitamin K status which is believed to be related to an increased risk of atherosclerosis and increas...
The main purpose of this study is to investigate whether and in which doses vitamin D intake is needed in order to maintain an adequate vitamin D status in 4-8 year-old Danish children dur...
People living at Northern latitudes are at risk of suffering from vitamin D insufficiency due to low sun exposure and the risk may be even more pronounced among elite swimmers since indoor...
This is a study to evaluate the effects of vitamin A supplementation program on the vitamin A status of preschool children. All children aged 3-5 years who do not have severe illness and a...
Background: Dietary intake of vitamin D includes vitamin D3 (VitD3), 25-hydroxyvitamin D3 (25OHD3) and vitamin D2 (VitD2). However, the bioactivity of the different species is currently no...
It is well-established that vitamin D status is closely associated with the susceptibility to infections. We aimed to study the association between vitamin D status and sepsis risk and death, and also...
Previous in vitro and in vivo studies indicate that enzymes that synthesize and metabolize vitamin D are magnesium dependent. Recent observational studies found that magnesium intake significantly int...
Vitamin D plays a key role in depression. In this study, we aimed to assess the prevalence of vitamin D deficiency or insufficiency and the association between vitamin D status and depression in patie...
Vitamin K is a cofactor for proteins involved in cardiovascular health, bone metabolism and cancer. Measuring uncarboxylated prothrombin, also termed as "protein induced by vitamin K absence or antago...
Vitamin D status is hypothesised to play a role in gestational glucose control. No studies to date have examined vitamin D in relation to changes in blood glucose in pregnancy. Thus, the aim was to ex...
A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.
An isomer of glucose that has traditionally been considered to be a B vitamin although it has an uncertain status as a vitamin and a deficiency syndrome has not been identified in man. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1379) Inositol phospholipids are important in signal transduction.
A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)
OXIDOREDUCTASES which mediate vitamin K metabolism by converting inactive vitamin K 2,3-epoxide to active vitamin K.
A family of phylloquinones that contains a ring of 2-methyl-1,4-naphthoquinone and an isoprenoid side chain. Members of this group of vitamin K 1 have only one double bond on the proximal isoprene unit. Rich sources of vitamin K 1 include green plants, algae, and photosynthetic bacteria. Vitamin K1 has antihemorrhagic and prothrombogenic activity.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
