S-Adenosylmethionine

SAMe tends to be on the pricier end as supplements go, but I know people who have found it tremendously helpful.

According to a webinar I watched (I know, grain of salt), it's especially helpful for folks with low dopamine or norepinephrine. L-phenylalanine can have similar effects.

Symptoms of low dopamine: no pleasure, no rewards, apathy, less love for loved ones, less "color" in life, no fun or interest in things, less spiritual connection or meaning.

Symptoms of low norepinephrine: low energy, low drive, hard to get going, don't finish what you start, want to sleep or hibernate, depressed, paranoid, doubt own survival, bored.
