I thought supplemental GABA doesn't cross the blood-brain barrier - GABA's only psychoactive when biosynthesized. How is this stuff effective?

Studies were done in '80, '81, '82, and '02 found that GABA did cross the blood-brain barrier, just in minuscule amounts. However, majority of the benefits are coming from the boost of immunoreactive GH (irGH) and immunofunctional GH (ifGH) growth hormones, by as much as 400%. If you are interested in the study, go to NIH PubMed and search for 18091016.

Is there a reason why California prop 65 warning label is on this product?

Where do you see a Prop 65 warning on this (GABA) product? I can't find one. Just check the CURRENT Prop 65 list and GABA is NOT on the list https://oehha.ca.gov/media/downloads/proposition-65//p65list112318.pdf

All the packages shown say 100 servings, how many servings for each size package? Thanks

I see what you mean about each package saying 100 servings per package. I figured out how many servings per package by dividing the serving size, 2500mg, into the weight of the package. The 250g package does contain 100 servings, the 500g package, 200 servings, and the kilo package contains 400 servings.

Just wondering, is there a serving scooper in there or do you just measure with your own instrument?

I've never gotten a serving scoop with these supplements but there is a guideline as to how many mgs per tsp etc. It may be very helpful to get one of the scales that measures tiny quantities.
