What are customized nootropics?

Customized nootropics are tailored blends created to enhance specific cognitive functions like focus, creativity, or task switching, instead of a generic "smart drug." These are usually blended following a personal assessment, such as a quiz, to suit individual needs and goals. Andrew Huberman discusses the use of ingredients like Alpha-GPC and phosphatidylserine in these blends, and mentions companies like Thesis, which allow customers to receive a starter kit of different formulas to find what best suits them 1 2.
