Serum concentrations of 25-hydroxyvitamin D (25-OHD) and 1,25-dihydroxyvitamin D [1,25-(OH)2D] of vitamin D2 and D3 origin were determined separately in 10 women before vitamin intake in early pregnancy, and repeated in maternal and cord seru …

Bouden S, Ben Messaoud M, Saidane O, Rouached L, Ben Tekaya A, Mahmoud I, Tekaya R, Dziri C, Abdelmoula L. Bouden S, et al. Eur J Clin Nutr. 2025 Apr;79(4):296-305. doi: 10.1038/s41430-024-01520-x. Epub 2024 Oct 9. Eur J Clin Nutr. 2025. PMID: 39385006
At present, cholecalciferol (vitamin D3) and ergocalciferol (vitamin D2) are the most commonly used compounds. Supplementation with calcifediol (25OHD3) rather than vitamin D itself should also be considered for the treatment. We performe …

Free versus total serum 25-hydroxyvitamin D in a murine model of colitis.
Larner DP, Jenkinson C, Chun RF, Westgate CSJ, Adams JS, Hewison M. Larner DP, et al. J Steroid Biochem Mol Biol. 2019 May;189:204-209. doi: 10.1016/j.jsbmb.2019.01.015. Epub 2019 Jan 30. J Steroid Biochem Mol Biol. 2019. PMID: 30710745 Free PMC article.
We have also shown in vitro that immune responses to 25OHD may depend on 'free' rather than total serum concentrations of 25OHD. To investigate the possible effects of free versus total 25OHD on anti-inflammatory immune responses in vivo we have …
