Welcome to my A – Z of Nutrition and ADHD series!
Over the course of these posts I’m hoping to raise awareness of the link between nutrition, lifestyle choices and ADHD symptoms.
N is for Neurotransmitters and ADHD
When it comes to ADHD, few things are more central than neurotransmitters — the brain’s chemical messengers that influence how we think, feel, and behave.
In ADHD, key neurotransmitters like dopamine and norepinephrine often function differently. These chemicals help regulate attention, motivation, memory, and emotional response — all areas that can be more challenging for neurodivergent brains.
That’s why stimulant medications (like methylphenidate or lisdexamfetamine) work: they increase dopamine and norepinephrine availability in the brain. But nutrition can also support these systems — gently, but meaningfully.
How food supports neurotransmitter health:
- Protein provides amino acids like tyrosine and tryptophan — building blocks of dopamine and serotonin
- Iron, zinc, magnesium, and B-vitamins are essential cofactors in neurotransmitter production
- Omega-3 fatty acids (especially EPA) support receptor sensitivity and brain cell communication
- Balanced blood sugar helps prevent neurotransmitter disruption from spikes and crashes
Think of food as part of your brain chemistry toolkit. While it may not replace medication, it can help the brain work with more stability and clarity.
Have you noticed a link between what you eat and how your brain feels?
