It's a tricky one, somebody needs to show some plausible biological mechanism ... causation not correlation.patrix wrote: ↑Fri Sep 23, 2022 10:01 am This made my friend a bit unsettled since he supplements with vitamin D and he started talking about a study that concluded that the telomeres in our DNA benefits from vitamin D. I chose to not bring up the problems with DNA research that in my view are just as grave as those in virology.
Edit: And investigating this further it seems that vitamin D in high concentration is used as a rodent poison.

Same thing as with fluoride then that actually was patented as a insecticide in the 19th century, but is now argued to be beneficial for dental health in low concentrations. I don't know about that anymore.
You should look into Linus Pauling who won a Nobel Prize but by the time he got into vitamins his political star had fallen. It's a weird story in a world of crazy stories. It's also a look at the "everything is dose related" issue. The good thing about vitamins is the toxicity is low, especially water soluble vitamins like Vitamin C, so they're probably mostly harmless anyway.
The only things I found that looked like flouride might be interesting was painting calcium flouride onto tooth enamel might help facilitate the natural process of the deposition of minerals into the enamel. You can get this done at a dentist. The adding of sodium flouride to random things you drink or even toothpaste doesn't have any logical connection to this except "flouride" is involved. I did read somewhere that sodium flouride would otherwise be a waste product of industry hard to dispose of, so that would provide a useful incentive.
