  1. @science· The Brain
    Adrenal-gland epinephrine cannot cross the blood-brain barrier. The brain produces its own in the locus coeruleus.
  2. @science· The Brain
    Receiving gratitude produces a stronger serotonin-related effect than giving it. Watching gratitude exchange can activate the observer’s serotonergic circuits.
  3. @science· The Brain
    Deliberate cold exposure is the most potent behavioral tool described for sustained dopamine increases, with dopamine and epinephrine reinforcing each other.
  4. @science· The Brain
    Caffeine does more than wake you through adrenaline and lower adenosine. It also increases dopamine receptor number and efficacy.
  5. @science· The Brain
    Early-day sunlight exposure to the eyes increases dopamine receptor availability, making dopamine more effective for motivation and mood.
  6. @science· The Brain
    Mucuna pruriens can spike dopamine sharply, then leave you facing a substantial crash.
  7. @science· The Brain
    L-tyrosine substantially increases dopamine within 15–45 minutes, with effects tapering after roughly 30 minutes to two hours.
  8. @science· The Brain
    Epinephrine creates neural energy: the desire and capacity to move and act, not merely calories.
  9. @science· The Brain
    Tryptophan sits upstream of serotonin synthesis the way tyrosine sits upstream of dopamine synthesis.
  10. @science· The Brain
    Dopamine, epinephrine, acetylcholine, and serotonin are shared ingredients behind changes in focus, energy, motivation, and relaxation.
  11. @science· The Brain
    Regular caffeine intake increases the number of D2 and D3 dopamine receptors.
  12. @science· The Brain
    L-tyrosine sensitivity varies wildly: some people tolerate 2 g, while others respond to 100 mg or nothing.
