Can you tell us if there is a supplement commercially available which is superior in effectiveness to any of these three, the Advanced Memory Formula, FocusIQ, and RediMind, for helping cognitive decline?

We do not like to close doors because there are many opportunities to learn from keeping a finger on the pulse and your eye on the ball in what is going on in the supplement arena. The reason is, there can be a new offering at any time appear and, if you are not surveying and searching at intervals purposefully for particular kinds of supplements, you may well miss something of great value. So our policy is to not get in the position of making a decree whether or not you are truly done or need to keep working on a particular agenda. Occasionally, that can be appropriate for limited and short-term objectives but is rarely doable for the big-picture items regarding severe health issues, for example.
