      Background: Circulating concentrations of biomarkers that are related to vitamin status vary by factors such as diet, fortification, and supplement use. Published biomarker concentrations have also been influenced by the ...
    • Tryptophan catabolites as metabolic markers of vitamin B-6 status evaluated in cohorts of healthy adults and cardiovascular patients 

      Ulvik, Arve; Midttun, Øivind; McCann, Adrian; Meyer, Klaus; Tell, Grethe S.; Nygård, Ottar; Ueland, Per Magne (Journal article; Peer reviewed, 2020)
      Background Vitamin B-6 status is routinely measured as pyridoxal 5′-phosphate (PLP) in plasma. Low concentrations of PLP are associated with rheumatic, cardiovascular, and neoplastic diseases. We have previously shown ...
    • Using metabolic profiling and gene expression analyses to explore molecular effects of replacing saturated fat with polyunsaturated fat-a randomized controlled dietary intervention study 

      Ulven, Stine Marie; Christensen, Jacob J.; Nygård, Ottar; Svardal, Asbjørn M.; Leder, Lena; Ottestad, Inger; Lysne, Vegard; Laupsa-Borge, Johnny; Ueland, Per Magne; Midttun, Øivind; Meyer, Klaus; McCann, Adrian; Andersen, Lene Frost; Holven, Kirsten Bjørklund (Peer reviewed; Journal article, 2019-04-26)
      Background: Replacing dietary saturated fatty acids (SFAs) with polyunsaturated fatty acids (PUFA) reduces the plasma low-density lipoprotein (LDL) cholesterol and subsequently the risk of cardiovascular disease. However, ...
