The article says a few rain drops in a swim pool . I don’t know if that is what the nurtritionist study says BUT the research going in the UK is using the following dosages
“Patients with mild to moderate Alzheimer’s disease were given either 30, 60 or 100mg of the drug or a placebo.
The 60mg dose produced the most pronounced effect - over 50 weeks there was a seven-point difference on a scale used to measure severity of dementia” BBC News 28July 2008
I believe the theory is that the article mixed up mg and mcg.
The researchers might actually be referring to mcg.
Seeing good effects at 60mcg ...
