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.

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...
Low levels of vitamin D are suspected to be a risk factor for cardiovascular disease and atherosclerosis. The aim of this study was to assess the prevalence of subclinical atherosclerosis among Inuit ...
Routine administration of vitamin A, recommended in CF patients, can help to prevent its deficiency. However, high vitamin A supplementation may lead to its excessive level and possible toxicity. Ther...

The relationship among inadequate vitamin D status, obesity, and cardiometabolic risk and the potential impact of physical activity-based interventions on vitamin D status are poorly characterized in ...
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...
