Serotonin is the hormone what makes us happy, so why aren’t we just injecting it into our body/taking it as tablets to get out of misery on command?
In: Biology
Neither injecting nor swallowing serotonin allows your brain to use it because it won’t cross from the blood to the brain.
Some drugs effectively increase the level of serotonin you experience by reducing how much of it your brain clears (eg Prozac) or forcing your brain to dump the serotonin it already has stored (eg MDMA).
