Interesting study. I see some problems with it though.

The grading was done by self-reporting of cognitive failures. This is a huge monkey wrench in the results making this study very week. Plus, the small cohort (60 people) is a weakness.

What this study says is that a much larger and complex study would be worthwhile. Nuero Cognitive testing to reduce the self-reporting weakness would be great.

It is KILLER expensive. It is $0.50 per capsule of 60 mgs of Enzogenol. The study was with 1000 mgs per day. That would be 16 capsules at a daily cost of $8.00. No wonder they sell if by the case at $29.50 per bottle of 60 capsules.
