My eye Doctor stressed the importance of good eye supplements to enhance the recovery of my vision. A supplement I had been using was no longer available (from any source). Amazon listed items I might be interested in and since I purchase other Eclectic Institute supplements this was listed.My Doctor is delighted with my recovery rate and I believe I can say this supplement has played a good part in that progress.I plan to continue with this supplement for as long as it is available.By the way since switching to Eclectic Institute for my other supplements, I feel that I am getting a consistent high quality supplement with improved results with the symptoms for which I am using those other supplements.
