A viewer asks: “How effective is creatine supplementation for cognitive performance compared to the memory-enhancing FocusIQ supplement from PrimalForce.net or the Advanced Memory Formula from Advanced Bionutritionals?” What can we tell him?

Creatine supplementation would be outranked by both of the other supplements you mentioned for improving cognitive performance. Again, the benefits of creatine are mostly significant in people who already are undernourished, particularly in respect to protein intake, such as those on vegan or vegetarian diets.
