There is a saying that one person’s medicine is another person
poison. A recent study published in the Journal of Ophthalmology
(Ophthalmology. 2013;120:2317-2323) indicted that 13% of
patients with a certain genotypes had a 135% higher rate of
progression of macular degeneration if they took certain vitamins
and mineral supplements! Vitamins made these people worse!
This is very frightening indeed! The very vitamins you thought
were helping might be making your vision worse.
