Found the study!
https://clinicaltrials.gov/ct2/show/NCT00382616
basically it’s two specific EPAs (fish oil omega 3s) 250 mg/d of eicosapentaenoic acid + docosahexaenoic acid . I’m not sure if he’s added PS or is using the oils as PS.. but
250 mg/d of eicosapentaenoic acid + docosahexaenoic acid provided as phosphatidylserine (300 mg/d PS-Omega3)
very interesting. I’m not sure it would be replacing ritalin but perhaps a synergistic effect with things like pine bark etc..?
