I had a stroke about nine months ago, and lost much of the peripheral vision on my right side. This much later, is there anything I can do that will help my recovery from stroke?
Cells that are affected by a stroke are screaming for energy. The best thing you can do for them is to give those cells the raw materials they need to create energy. I've written about my Awesome Foursome—CoQ10, L-carnitine, magnesium, and D-ribose—and how they help generate energy in cells. I think they'd be helpful in your stroke recovery time.
I'd also suggest that you take lutein, to help with the retinal cells.
You might also investigate hyperbaric oxygen therapy (HBOT), which has been shown to help patients’ recovery from stroke long after the event. There are quite a few around the country. Find an HBOT provider near you.
