mostly related to ingredient dosage- number of caps increased to 120.. daily dose increased to 4. some of the ingredient dosage remain the same because increasing them would only benefit a very limited group who would be dosing higher anyways. particularly those with alzheimers or other degenerative conditions.
choline bitartrate replaced by the considerably more effective choline dihydrogen citrate- amount also increased amount by 50% per cap ( doubled over daily dosage) (choline depletion was an issue for some with earlier version)
amount of vinpocetine significantly increased/per cap and daily.
overall 2-oxo and other dosages increased- not per cap but over daily.
while price remains the same-- so would say thats a significant improvement
