Description

Description générale

Cholecalciferol acts as a hormone precursor since it requires two stages of metabolism: first to 25-hydroxycholecalciferol; then to 1α, 25-dihydroxycholecalciferol. One unit (U.S.P. or international) is defined as the activity of 0.025 μg of vitamin D3 contained in the USP vitamin D reference standard.

Cholecalciferol is sourced either through the diet or exposing skin to ultraviolet rays. Oral administration of vitamin D₃ is readily absorbed and is stored in adipose tissue.

Application

• Alterations in regulators of the renal-bone axis, inflammation and iron status in older people with early renal impairment and the effect of vitamin D supplementation.: This study delves into the significant roles of cholecalciferol in modulating the renal-bone axis, inflammatory responses, and iron metabolism in elderly patients with renal impairment. Through vitamin D supplementation, researchers observed pivotal changes that could guide future therapeutic strategies (Christodoulou M et al., 2024).


• Investigating the effects of 25-hydroxyvitamin D3 on clinical outcomes in multiple sclerosis patients: A randomized, double-blind clinical trial- a pilot study.: This clinical trial assesses the efficacy of cholecalciferol in improving the health outcomes of patients with multiple sclerosis. The use of cholecalciferol potentially enhances neurological function and reduces disease progression, illustrating its vital role in neurodegenerative disease management (Maghbooli Z et al., 2024).


• Vitamin D regulates COVID-19 associated severity by suppressing the NLRP3 inflammasome pathway.: This pivotal research links cholecalciferol to the reduction of COVID-19 severity through its regulatory effects on the NLRP3 inflammasome pathway. The findings underscore the potential of vitamin D as a modulatory agent in the immune response against viral infections (Khalil B et al., 2024).


• Effects of Vitamin D Supplementation on Central Hemodynamic Parameters and Autonomic Nervous System in Obese or Overweight Individuals.: This randomized controlled trial explores how cholecalciferol supplementation can affect cardiovascular and autonomic functions in obese or overweight patients, providing insights into its benefits beyond bone health and into cardiovascular regulation (Faria ACC et al., 2024).

Actions biochimiques/physiologiques

La vitamine D fonctionne à travers une récepteur qui fait partie de la famille des facteurs de transcription dépendant du ligand. Module la prolifération et la différentiation des cellules à la fois cancéreuses et normales. A des effets antiprolifératifs et anti-métastatiques sur les cellules cancéreuses de poumons, du colon et de la prostate. Les récepteurs activés de la vitamine D de l′intestin et des os maintiennent l′absorbance du calcium et l′homeostase.

Deficiency of vitamin D is often observed in chronic kidney disease.

Stockage et stabilité

Cholecalciferol C9756 is packaged under argon gas. If it is stored unopened at 2-8°C and protected from light, this product should be stable for a minimum of three years. Unused portions should be stored under nitrogen or argon gas. Deterioration is negligible after storage of one year in amber-evaculated ampules at refrigerator temperatures. It is oxidized and inactivated by moist air within a few days.
