Neurotransmitters 101: How Your Brain Sends Signals

Neurotransmitters are the chemical messengers your neurons use to talk to each other. Understanding them — even at a basic level — makes a lot of "cognitive" advice (about sleep, food, focus, mood) suddenly make sense.

The Big Six

• Dopamine — motivation, reward, and focused attention. Made from the amino acid tyrosine.
• Serotonin — mood regulation, satiety, sleep onset. Made from tryptophan.
• Norepinephrine — alertness, stress response, memory encoding.
• Acetylcholine — learning, muscle contraction, REM sleep. Made from choline.
• GABA — the main inhibitory transmitter; calms neural activity.
• Glutamate — the main excitatory transmitter; involved in every memory and thought.

How They Work

When a neuron fires, it releases neurotransmitters from tiny sacs at the end of its axon. These molecules cross the synaptic gap and bind to receptors on the next neuron, either exciting or inhibiting it. Cognition is essentially the summed activity of these signals — trillions of them, every second.

What Neurotransmitter Production Depends On

Neurotransmitters are built from amino acids. Their synthesis requires cofactors — mostly B vitamins (B6, B9, B12) and minerals. So neurotransmitter production is only as good as your nutritional base.

Where Circulation Comes In

Even with plenty of amino acids and cofactors on hand, neurons can't produce or release neurotransmitters efficiently if they don't have enough oxygen and ATP. That's why cerebral blood flow and NAD+ support (both addressed by MemoHoney®'s formula) sit upstream of neurotransmitter function.

Practical Takeaway

Support neurotransmitter systems the physiological way: eat enough protein for amino acid supply, cover the B vitamins, protect sleep (when many neurotransmitter stores are replenished), and support circulation so neurons have the energy to use everything else. See B vitamins and brain health.
