I’d argue that PEA and Alpha-GPC would more compliment each other, if anything, than actually synergise, but let’s not focus on that point. They do mention the lotus as a potential AChE-I, but I’d wager to say it’s not as potent in this regard as things like huperzine, galantamine, and sage, and people still find that it’s best to use a solid dose of Alpha-GPC with these more proven, and likely more potent, AChE-Is. 250-300mg is the “low” effective dose for Alpha-GPC, with 600mg being a “higher” effective dose. Even if you cut the 250mg in half, you have 125mg. You’d have to half that dose to get near the 50mg they have, and you’d still be 12.5mg short of that 62.5mg. I’m not saying it’s not going to be a decent product, but, personally, I’d write off the 50mg of Alpha-GPC as pretty useless, and definitely not a key factor in the product’s effectiveness or as a major selling point.
