I think the 3-6 months is talking about how long it will take WITH optimal treatment. So if you don't start optimal treatment until 2 months after your injury, you should probably expect to be better in 5-8 months from the injury.

That's how I understood it, anyway.

Does anybody know of a nutritional supplement that includes many or all of the substances mentioned in the article?

And, yes, eat more blueberries (at least they're yummy!).
