Is the Brain Power Protocol from Dr. Al Sears safe and effective for restoring better brain functioning for the ability to concentrate, remember, and process information? He claims this protocol has taken an average of 21 years of aging off their neurological age. Is that a valid claim?

This is not overstating things. This is a carefully worked out plan and he has much feedback from his own patient pool which validates the wisdom of the various components as well as their combination, which is the ultimate strength here. As you know, for many sources of benefit to the physical well-being of a person, things may be redundant, additive if they each contribute something so the overall benefit will be potentially greater, or they can be synergistic to produce a greater benefit than the individual components would accomplish used singly. That is the case with this protocol, it is a synergistic healing system that has great merit.
