General description
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.: Diese Studie erforscht die bedeutende Rolle von Cholecalciferol bei der Modulation der Knochen-Nieren-Achse, von Entzündungsreaktionen und des Eisenstoffwechsels bei älteren Patienten mit Nierenfunktionsstörungen. Bei Vitamin-D-Supplementierung beobachteten die Forscher bedeutende Veränderungen, die als Anhaltspunkt für zukünftige therapeutische Strategien dienen könnten (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.: Diese klinische Studie bewertet die Wirksamkeit von Cholecalciferol bei der Verbesserung der Gesundheitsergebnisse von Patienten mit Multipler Sklerose. Der Einsatz von Cholecalciferol kann die neurologische Funktion verbessern und die Krankheitsprogression verringern, was seine bedeutende Rolle bei der Behandlung neurodegenerativer Erkrankungen verdeutlicht (Maghbooli Z et al., 2024).
- Vitamin D regulates COVID-19 associated severity by suppressing the NLRP3 inflammasome pathway.: Diese Zulassungsstudie stellt aufgrund der regulatorischen Auswirkungen auf den NLRP3-Inflammasom-Signalweg eine Verbindung zwischen Cholecalciferol und einer verringerten Schwere von COVID-19 her. Die Ergebnisse unterstreichen das Potenzial von Vitamin D als modulatorischer Wirkstoff bei der Immunantwort gegen Virusinfektionen (Khalil B et al., 2024).
- Effects of Vitamin D Supplementation on Central Hemodynamic Parameters and Autonomic Nervous System in Obese or Overweight Individuals.: In dieser randomisierten kontrollierten Studie wird untersucht, wie die Cholecalciferol-Supplementierung die kardiovaskulären und autonomen Funktionen bei adipösen oder übergewichtigen Patienten beeinflussen kann. Sie liefert Einblicke in die Vorteile dieser Supplementierung über die Knochengesundheit hinaus und bis hin zur kardiovaskulären Regulierung (Faria ACC et al., 2024).

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

Hi Please advise how to make retest for your products C9756-5G Regards
1 answer-
Products are retested according to the schedule set by Quality guidelines. In the case of C9756, the retest occurs every 3 years. Retesting only occurs if ample stock is available of the specific lot. Product retesting is not performed if the batch has sold out, nor is retesting performed upon request. Should stock remain, retesting will be performed near the assigned retest date. Should the lot continue to meet all specifications, the lot retest date is extended and an updated Certificate of Analysis will be generated.
