Sun pills, hot drama
We're learning more about what Vitamin D does to our bodies
Vitamin D drama: NHS penny‑pinching, wild dreams, and heart jitters
TLDR: New research suggests vitamin D may influence immunity and blood pressure beyond bone health. Commenters clash over a doctor refusing prescriptions, warn about toxicity and weird side effects, and share wild “vivid dream” stories—making vitamin D a winter must‑debate, if not a must‑dose.
MIT Tech Review says the “sunshine vitamin” isn’t just about bones—it may sway the immune system and blood pressure, though the heart‑attack evidence is mixed. But the real show is the comments. The author’s UK doctor wouldn’t prescribe vitamin D because “everyone” is deficient and it’s too pricey for the NHS, and the thread erupted. One camp cried bureaucratic fail, another shrugged, just buy it at the pharmacy. Read the piece here: MIT Technology Review.
The hottest take came from a fed‑up reader blasting “incompetent medical systems,” while a pragmatist noted supplements are cheap off the shelf. Cue the caution squad: you can take too much, warned one commenter, waving the toxicity flag and reminding folks that a basic multivitamin might be plenty. Meanwhile, the anecdotes went full late‑night TV. One user swears a specific brand gave them guaranteed vivid dreams—and claims their friends all had the same trippy result. Another says heavy dosing during the pandemic left them feeling like their heart was trying to escape their chest.
So yes, vitamin D might help your defenses against colds and your blood pressure, but the community turned it into a winter circus: D‑believers vs. D‑doubters, policy vs. personal stash, and a chorus of “talk to your doctor” over the drumbeat of memes about sun pills and moon dreams.
Key Points
- •Vitamin D is crucial for calcium absorption and bone remodeling; deficiency causes rickets, and infants are advised to receive supplements until at least one year old.
- •Research links vitamin D deficiency to high blood pressure; supplementation on a daily or weekly basis can lower blood pressure in deficient individuals.
- •Vitamin D deficiency is associated with increased risk of cardiovascular events, though evidence is mixed on whether supplements reduce these events.
- •Low vitamin D levels have been linked to higher incidence of the common cold, and supplements can modulate gene expression of immune-related proteins.
- •Seasonal reductions in sunlight, especially in the Northern Hemisphere, make vitamin D intake considerations more important during winter.
