The group discusses the safety of vitamin D doses, citing studies that typically mention 4000 IU as a safe upper limit, but some posts question or suggest lower thresholds like 1000 IU, emphasizing the ongoing debate. The tone varies from scientific references to cautious paraphrasing, highlighting the importance of dosage management in health practices.
AgreementModerate agreement
Most discussions acknowledge that traditional safety limits like 4000 IU are being reconsidered, with some posts supporting the idea of lower or different upper limits based on recent studies.
InterestHigh interest
The discussions show high curiosity about dosage safety, new research findings, and clinical implications, indicated by questions and references to scientific studies.
EngagementModerate engagement
Participants refer to specific research, mention doses, and debate clinical practices, reflecting moderate depth of engagement.
ImpactModerate impact
The conversations suggest a recognition of the potential influence of this research on health recommendations and clinical guidelines, though some posts are more cautious, indicating moderate impact.
Abstract in brief
The traditionally accepted safe upper limit for vitamin D intake is 4000 IU daily, but recent research suggests that the risk of adverse effects may depend on factors such as dose, treatment plan, age, sex, and baseline vitamin D levels.
Excessive vitamin D intake can lead to health issues like hypercalcemia, hypercalciuria, and mineral deposits in soft tissues, and the therapeutic window might be narrower than previously thought.
For preventing or correcting deficiency, doses of 800-1000 IU daily or 10 micrograms of calcifediol are considered safe, while higher doses over the long term or in intermittent treatments could pose risks.]
Pero muchas veces no se presta atención a este valor, por lo que no se toman medidas para corregirlo.

@goddeketal The prevention and correction of vitamin D deficiency with 800-1000 IU/daily of vitamin D or 10 µg/day of calcifediol are safe. Because of their potential harm, larger doses given on the long term or in intermittent regimens should not be selected.

En éste otro estudio marcan el límite como 1000 ui.
De lo que no habla ninguno de los dos estudios es de usarla con k2 para que no se produzcan depósitos de calcio.

@MonsieurAlazon @ricB435183 @Tometprazole @NightHaunter on peut jouer la carte du scientiste mais mieux vaut avoir du fond.
On donne des doses de 100 000 UI aux personnes âgées.
4000 UI par jour chez des adultes est considéré comme sûr chez springer.

@G73528023 @punktpreradovic @MeyerMeyer64 Ich würde mich eher auf wissenschaftliche Studien beziehen. Seriöse Wissenschaftler und Ärzte nennen ihre Quellen. Die folgende Studie nennt 4000 IE/Tag als maximale Tagesdosis. Selbst bei dieser Dosis gab es bei 9% negative Effekte (Kalziumeinlagerungen) https://t.co/I7pXuui3kB

@atalorico @AxelRollie @yerbs7 @foundmyfitness 1/ he did not have polycystic kidney, only his siblings. As it is a dominant mutation, he had 50% chance to have it and actually did not have it. 2/ it is not a receptor but a cytochrome CYP24a1.

Review of the dosing of vitamin D for bone health, fall risk, frailty, kidney stones and mortality.
Some studies have found adverse effects when using very high doses, so should upper limit of 100 micrograms/4,000 IU per day be revised?
