While ADHD is often discussed through the lens of behavior and medication, emerging research suggests nutrition—particularly mineral status—may play a meaningful supporting role.

Iron, zinc and magnesium are essential for brain development and neurotransmitter activity, including dopamine regulation, which plays a key role in attention and impulse control. A well-cited clinical study conducted at Hacettepe University School of Medicine in Ankara, Turkey, found that children diagnosed with ADHD had significantly lower levels of iron and zinc compared to children without ADHD. These findings have since been echoed in additional international research.

Iron supports oxygen delivery to the brain and steady cognitive energy. Zinc plays a role in neurotransmitter signaling and may influence hyperactivity and impulsivity. Magnesium, involved in hundreds of biochemical processes, supports nervous system balance and may help with emotional regulation and sleep—two common challenges for individuals with ADHD.

Rather than positioning supplements as a fix, researchers increasingly emphasize food-first strategies. Mineral-rich foods such as leafy greens, legumes, nuts, seeds, whole grains, eggs, lean meats and seafood offer gentle, foundational nourishment that supports brain health over time.

As with all aspects of nutrition, individual needs vary. Paying attention to overall dietary patterns—and how the body responds—can be a meaningful part of a broader, supportive approach to attention, focus, and emotional balance.
