Functional Nutritionist for ADHD
Offering Virtual Appointments in North Carolina, Across the United States, and Worldwide
If you or your child has ADHD or ADD and you feel like medication is managing symptoms but not actually solving anything, you are not alone. Many families reach a point where they want to understand what is driving the condition, not just suppress it.
As a functional ADHD nutritionist, I go beyond general healthy eating advice to investigate the specific biochemical imbalances that affect focus, impulse control, mood regulation, and behavior.
Nutrient deficiencies, methylation patterns, gut health, and blood sugar dysregulation all play a measurable role in how ADHD presents, and in many cases working with an undermethylation nutritionist can help address one of the primary biochemical drivers.

Does This Sound Like You?
People who reach out for ADHD nutrition support often describe:
- Difficulty sustaining attention on tasks that aren’t immediately interesting or stimulating
- Impulsivity that creates problems at school, work, or in relationships
- Hyperactivity, restlessness, or an inability to sit still and feel calm
- Emotional dysregulation, quick frustration, or intense reactions to small setbacks
- Chronic disorganization, forgetfulness, or difficulty following through on plans
- Sleep problems, including difficulty winding down or waking feeling unrefreshed
- Inconsistent eating patterns, strong food cravings, or appetite changes related to medication
- A child whose ADHD symptoms are affecting school performance, friendships, or daily family life
- Trying stimulant medication with partial relief or unwanted side effects
Medication can play an important role for many people with ADHD. But it doesn’t address the nutritional and biochemical environment in which the brain is operating. That is where functional nutrition comes in.
Who I Am and How I Help With ADHD
I’m Samantha Gilbert, a certified functional nutritionist based in North Carolina with over 20 years of experience supporting children and adults with ADHD, anxiety, depression, OCD, and autism.
My approach to ADHD is rooted in one core principle: symptoms are signals. Inattention, hyperactivity, and impulsivity are the brain’s response to an internal biochemical environment that isn’t fully supported. My job is to investigate what that environment looks like for you or your child specifically, identify the imbalances, and create a personalized nutrition plan to address them.
In some cases, elevated copper levels can overstimulate the nervous system and contribute to these symptoms, which is why working with a copper toxicity nutritionist may be an important part of the process.
I provide nutrition education and guidance, not diagnosis or medical treatment. I regularly collaborate with pediatricians, psychiatrists, and behavioral therapists to support coordinated, whole-person care.
Why My Clients Trust Me:
- Over 20 years of functional nutrition experience
- Extensive experience supporting children and adults with ADHD and ADD
- Deep specialization in the biochemical and nutritional drivers of attention and behavior
- Root-cause approach that goes beyond symptom management
- Real stories of success from clients and families

How Nutrition Plays a Role in ADHD
From a functional nutrition perspective, ADHD symptoms are influenced by far more than brain structure alone. The most common underlying patterns I investigate include:
Dopamine and Neurotransmitter Pathways
ADHD is closely linked to low dopamine activity in the brain's attention and reward circuits. The nutrients required to produce and regulate dopamine, including zinc, vitamin B6, and specific amino acids, are frequently depleted in people with ADHD. Supporting these pathways nutritionally can make a meaningful difference in focus, motivation, and impulse control. In cases where zinc depletion is more significant, working with a zinc deficiency nutritionist can help restore these pathways more effectively.
Methylation Imbalances
Both undermethylation and overmethylation affect how the brain produces and breaks down neurotransmitters. Identifying your methylation type is a key step in understanding why ADHD presents the way it does, and in tailoring a nutritional protocol that works with your individual biochemistry rather than against it. In cases where excess neurotransmitter activity is present, working with an overmethylation nutritionist can help guide a more targeted approach.
Pyrrole Disorder
Pyrrole disorder (pyroluria) chronically depletes zinc and vitamin B6, two nutrients critical for dopamine and serotonin production, stress tolerance, and emotional regulation. It is extremely common in people with ADHD and frequently goes undiagnosed. Addressing pyrrole disorder can produce significant improvements in behavior, attention, and emotional stability.
Nutrient Deficiencies
Research consistently links ADHD severity with low levels of zinc, magnesium, fatty acids, and vitamin D. These are not optional extras for brain function. They are foundational. Standard diets, picky eating common in children with ADHD, and medication side effects that suppress appetite all compound the risk of these deficiencies.
Blood Sugar Dysregulation
Unstable blood sugar directly impairs focus, patience, and emotional regulation. For many people with ADHD, the pattern of skipping meals, craving sugar, or eating erratically creates a cycle of brain energy crashes that makes symptoms significantly worse throughout the day.
Gut Health and the Gut-Brain Axis
The gut produces a large portion of the brain's neurotransmitters and is in constant communication with the central nervous system. Dysbiosis, leaky gut, and food sensitivities can all worsen ADHD symptoms by increasing systemic inflammation and disrupting dopamine and serotonin production at the source.
What Clients Often Notice Over Time
Every person’s experience is different, but clients working with a functional ADHD nutritionist commonly report:
-
Improved focus and sustained attention
-
Calmer, more regulated behavior, especially in children
-
Better emotional stability and frustration tolerance
-
More consistent energy without peaks and crashes
-
Improved sleep quality
-
Reduced intensity of ADHD symptoms overall
-
Better appetite and more varied food intake in children
-
Less reliance on stimulant medication over time, in coordination with their prescribing physician
There are no overnight transformations. But when the brain has the biochemical support it needs, the improvements that follow are real, measurable, and lasting.

ADHD Nutrition: Common Questions
Can a nutritionist actually help with ADHD?
Yes, though in a different way than medication. A functional ADHD nutritionist investigates the biochemical factors influencing attention, behavior, and mood: nutrient status, methylation, dopamine pathway support, gut health, and blood sugar regulation. When these factors are addressed, many people experience meaningful and lasting improvement in ADHD symptoms.
How is this different from just eating healthier?
General healthy eating is a good start but it doesn’t identify your specific imbalances. Functional nutrition for ADHD involves detailed symptom assessment and lab testing to pinpoint what is actually depleted or disrupted in your individual biochemistry, then builds a plan around that rather than general food quality guidelines.
My child is on stimulant medication. Can you still help?
Yes. Nutrition support works alongside existing medical treatment. I don’t advise on medication changes, but many families find that addressing nutritional imbalances improves how their child responds to medication and, over time, may reduce the dose needed, in coordination with their prescribing physician.
Do you work with adults with ADHD?
Yes. Adult ADHD is a significant area of my practice. The same biochemical patterns, including methylation, pyrrole disorder, dopamine support, and gut health, are just as relevant for adults as they are for children.
My child is an extremely picky eater. Can nutrition still help?
Yes, and this is very common. Picky eating in children with ADHD is often connected to sensory processing, gut dysbiosis, or nutritional deficiencies themselves. I factor this into the plan and work with what is realistic for the family rather than pushing an idealized diet the child won’t follow.
Do you require lab testing?
Labs are an important part of the process. They help me understand the specific biochemical picture for you or your child so the plan is targeted, not guesswork. I’ll guide you on exactly which tests are most relevant.
Is this available if I don't live in North Carolina?
Yes. All sessions are virtual. I work with clients across North Carolina, the United States, and worldwide.
How long before we notice changes?
It varies depending on how many layers of imbalance are involved. Some families notice meaningful changes in behavior or focus within the first few weeks. Others need gradual adjustments over several months. The focus is always on sustainable, root-cause change.
Ready to Take the Next Step?
ADHD doesn’t have to mean a lifetime of managing symptoms without ever understanding their source. If you are looking for a functional ADHD nutritionist who will dig into what is actually driving the condition and build a plan around your unique biochemistry, this is where to start.
