Remember this product? I have no idea why you guys stopped making it but I have 3 bottles with a manufacturing date of 07/13. I have no idea how this translates into an expiration date I just want to know if they're still good to take. No other companies are making a 3 4 divanillyltetrahydrofuran supplement that has divanil as its only active ingredient so I'm not sure what to do. Thanks for any help
