Answer:

Supplements such as Happy Stack (Pure Nootropics), The Brain Booster Stack (from Vitamonk LLC) and similar "stacks" contain combinations of "nootropic" ingredients that supposedly enhance memory, cognitive function, and/or mood. The combinations vary, but typically include uridine (as uridine 5'monophosphate) and choline (as alpha-GPC) and may include other ingredients, such as docosahexaenoic acid (DHA), an omega-3 fatty acid.
