It does make you more tired at night, but this makes sense because of the higher quality work your mind did during the day. And of course, you need to sleep to let your mind fully process the memories you made all day long.

And another question, how quickly does alpha-gpc work?

Alpha-GPC increases acetylcholine levels almost immediately, so you can expect to feel the effects 20-30 minutes after ingestion. Then, does alpha-gpc increase serotonin? In animal models, alpha-GPC has demonstrated a monoaminergic profile (i.e., liberating or involving monoamines, such as serotonin or dopamine, in neural transmission), and supplementation has been shown to improve synaptic signaling, as well as support brain reorganization and functional recovery after injury.

Correspondingly, does choline increase dopamine?

CHOLINE AND THE BRAIN Studies in animals suggest that CDP-choline supplements increase dopamine receptor densities and can ameliorate memory impairment. In Parkinson's disease, for example, CDP-choline may increase the availability of dopamine. You can also ask which form of choline is best? The single most effective supplement for raising brain choline availability is Citicoline. A close second is Alpha-GPC. Either of these cholinergics will quickly increase acetylcholine and phosphatidylcholine levels in the brain.

Is Cognizin the same as citicoline?

Citicoline freebase is available in dietary supplements in the U.S. Japanese company Kyowa Hakko produces citicoline freebase by using a patented and natural fermentation process. It goes by the brand name Cognizin and can be found in nutritional supplements sold by numerous manufacturers.
