For many parents and therapists navigating the world of sensory processing disorder (SPD), questions about holistic approaches often arise. One area gaining traction is the use of dietary supplements to support children with sensory challenges.
But do they really help? What does the research say and how can you make safe, informed choices?
In this article, we break down what SPD is, why supplements are being considered, and what current studies reveal about their effectiveness.
Important Reminder: Always consult your child’s healthcare provider before adding any supplement to their routine.
Sensory Processing Disorder refers to the brain's difficulty receiving and responding appropriately to information from the senses. We all have eight sensory systems—sight, sound, smell, taste, touch, proprioception (body awareness), vestibular (balance and movement), and interoception (internal sensations like hunger or emotions).
In children with SPD, one or more of these systems may become overwhelmed or under-responsive, impacting daily activities like getting dressed, eating, socializing, or learning. While SPD often coexists with conditions like ADHD or autism, it's important to note that sensory challenges can exist independently as well.
Parents and professionals are increasingly exploring supplements as part of a broader toolkit to support nervous system regulation. The reasons are clear:
Picky Eating is common among children with SPD, leading to nutritional gaps.
Modern Diets often lack essential micronutrients due to processing and depleted soil quality.
Gut-Brain Connection research shows that gut health can influence behavior and emotional regulation.
That said, supplements are not a standalone solution. They are best used as part of a holistic approach that may include occupational therapy, sensory diets, and lifestyle changes.
Recent meta-analyses and clinical studies have identified several supplements that may support behavioral regulation, attention, and nervous system health in children. Here's a breakdown of the most researched options:
Children with SPD often have limited diets, which may lead to deficiencies in key vitamins and minerals. High-quality multivitamins can fill these gaps and support overall regulation.
OT Tip: Choose multivitamins with third-party testing to ensure ingredient accuracy and safety.
Known as the "sunshine vitamin," Vitamin D supports mood regulation, dopamine production, and immune health. It's often deficient in children who spend significant time indoors or live in areas with low sunlight.
How to Supplement: Vitamin D is best absorbed with healthy fats. Look for D3 combined with K2.
These essential fats are crucial for brain development, focus, and emotional regulation. Studies show that children with ADHD and SPD often have lower levels of DHA.
Evidence: A 2023 meta-analysis found that Omega-3 supplementation improved attention and behavior in over half of the included studies.
Challenge: Many Omega-3s taste fishy, so gummies or flavored liquids may be more palatable.
L-Carnitine plays a role in energy metabolism and nervous system function. Preliminary studies suggest it may improve focus and behavior in children with neurodevelopmental disorders.
The gut and brain are closely linked. Many children with autism or SPD experience gut dysbiosis or chronic constipation.
Probiotics support digestion, nutrient absorption, and may improve mood and sensory regulation.
Observation: Many parents report improved regularity and calmer behavior when probiotics are introduced.
Note: Supplements like CoQ10, NAC, and B vitamins are also being explored, but more research is needed to confirm their effects on SPD.
In the podcast, Rachel and Jessica raised an important caution: not all supplements are created equal.
"More than half of the supplements you’ll find on Amazon don’t contain the ingredients they claim to."
Because supplement regulation is limited, it's essential to:
Purchase directly from reputable brands or the manufacturer's website.
Look for third-party testing and clean ingredient lists.
Avoid supplements with artificial dyes, fillers, or added sugar.
Adding too many supplements at once can make it difficult to gauge what’s working. Instead, follow a thoughtful plan:
Start with one supplement for 4–6 weeks.
Observe and document changes in mood, digestion, sleep, and behavior.
Consult with a healthcare provider, especially if your child is on medications.
A functional medicine doctor or pediatric nutritionist can be especially helpful in identifying deficiencies through testing and guiding supplement selection.
Supplements can be a helpful addition to your child’s sensory toolkit, especially when combined with consistent routines, sensory activities, and support from occupational therapy. While the research is still emerging, many families find improvements in behavior, regulation, and daily function through targeted supplementation.
Remember: You know your child best. Start slow, stay observant, and always seek guidance when needed.
