Use of calcifediol in gilthead seabream (Sparus aurata): Effects on growth performance, biochemical composition, skeletal anomalies and histology

Aquaculture Reports
Vitamin D3 is the typical vitamin D supplement in aquafeeds, but this form requires further metabolization to the active form. Calcifediol is used in livestock as an alternative, however it isn’t common in aquaculture.

Calcifediol in patients with hip fractures

International Journal of Bone Fragility, 2023
Vitamin D deficiency has a high prevalence in the elderly population. This condition can cause sarcopenia and osteoporomalacia, which are associated with an increased risk of falls and fractures, especially of the proximal femur. These fractures have devastating consequences in terms of mortality, disability, and healthcare and social costs ...

Estimation of the influence of exogenous factors on the vitamin D deficiency in pregnant women in Saint Petersburg [PDF]

Гинекология, 2017
Vitamin D is a precursor of calcitriol, a secosteroid hormone regulating calcium-phosphorus metabolism and a wide range of proliferative and immune responses. Solar UV radiation (290-315 nm) is an initiator of vitamin D production in the human skin.

Effect of calcifediol supplementation on renin‐angiotensin‐aldosterone system mediators in dogs with chronic kidney disease

Journal of Veterinary Internal Medicine, 2022
Background Chronic kidney disease (CKD) leads to low serum concentrations of vitamin D metabolites. Thus, hypovitaminosis D associated with CKD might contribute to disease progression via increased concentration of renin angiotensin aldosterone system ...
