Reply to comment by merlinsbeers in Vitamin D deficiency linked to premature death. Over a 14-year follow up period, researchers found that the risk for death significantly decreased with increased vitamin D concentrations, with the strongest effects seen among those with severe deficiencies. by Wagamaga

How does ability to absorb nutritional vitamin D decline with age? My understanding is that nutritional intake (older people eat less, and less varied foods) generally decreases with age but not absorptive capacity for fat soluble vitamins.

The article I linked specifically advises against large dose vitamin D supplements.

The article also mentions why widespread vitamin d monitoring without a diagnostic indication is a poor idea with limited benefit.

Not sure of why. It just stops being absorbed in the gut as much, and sunshine becomes less effective at producing it even with high exposure.

Doc gave me 10000-unit pills to take weekly for a few weeks then told me to keep taking 2-5000 units a day forever.

D is involved in the chickpea that produce energy, and if I miss several days I can feel it. When I'm on target the fog and malaise go away and I feel like a normal person.

Everyone past their early 40s should get their vitamin panel checked, especially if they feel like they're run-down for no good reason.

I'm not scaling the paywall to verify the article, but if it doesn't talk about the decline with age or it says these dosages are not the medicine for it, then it didn't do its homework.

It’s not a paywall, signup is free. You should read the article, it’s the largest ever study conducted on vitamin D levels. Your opinion does not align with that of the physician researchers who conducted that study.

My time isn't free nor is my email address. They may have asked the wrong questions.

Feel free to use your access to the article to excerpt quotes from it that contradict what I've said.

In particular, they need to say that vitamin D absorption and creation do not decline with age, and that daily doses in the 2000 to 5000-IU range are too high to fix that.

If they don't say that, then my opinion does not conflict with their study, or you didn't understand the study.

And even if they do say that it doesn't mean that they're right and I'm wrong. My opinion conflicts with a lot of "physician researchers" on a lot of topics. Quacks publish, too.
