The AREDS (age related eye disease
study) does not show the efficacy and
safety of taking a high dose vitamin beyond 8-9 years. So, unless you've got a family history of ARMD or currently have intermediate stage MD, or other retinal/macular problems the benefits of taking an AREDS supplement is unknown. Although, the scientific community is currently researching the benefits/risks of long-term usage of the supplements, the results won't be published for another few more years.
