Honestly, the only people that bring this up are people still steadfast against fluoridation of water and people looking for an overly simplistic cause for alzheimer's.
Not only that, but your study observed extreme cases: "The majority of patients included in the study had a history of seizures or minor head injury."
I never heard of calcification linked with fluoridation and Alzheimer's. So I wasn't suggesting that.
Apparantly you've never given magnesium citrate to older family members and watched them get the best sleep in a long time. Moreover, an American diet filled with calcium + little magnesium + Americans taking calcium supplements for osteo-porosis + plus deficiency of various nutrients is bound to lead to various problems. Then again, I'm not a doctor. In fact, I don't even have a college degree. So feel free to ignore anything I say.
If people want to be more concerned about vitamins/supplements rather than a diet rich in iron/HFCS + deadly FDA-approved drugs, so be it. I will take my chance with the vitamin fanatics like Linus Pauling (took mega doses of Vitamin C, died of cancer... at the age of 93).
I will grant your wish. I will stop talking about vitamins and supplements on HN. However, for any crackpot vitamin fanatics out there, head over to http://knowledgeofhealth.com That's one of the best sites I know and are very good at spotting mistakes in mediocre research proving that vitamins are deadly, cancer inducing toxins.
300 - 600 mg: magnesium citrate.
My favorite brand is "30 Minutes of Sunshine" http://www.lifespannutrition.com/lsn/products.asp?itemnumber... Bio-Tech Vitamin D3 is also very good: http://www.biotechpharmacal.com/
