Exploring Nutritional Strategies to Support Brain Health in Individuals with Autism

There’s been a rise in autism diagnoses in the UK, a trend highlighted by The Guardian back in March. In England, many children are still waiting for an official autism or cerebral palsy diagnosis. But even after the diagnosis, there’s no cure in sight. Now, more than ever, it’s crucial to explore supportive therapies that can boost brain health for individuals with autism.

In this article, we’ll dive into some nutrition-based ways to boost brain health for individuals with autism. From essential vitamins and minerals to game-changing options like NMN supplements for cellular health, we’ll cover how these strategies can help create a more balanced and healthier life.

The Link Between Autism and Brain Health

Autism is a developmental condition that affects how a person communicates, interacts socially, and processes information. It presents differently in each individual, with symptoms ranging from mild to more complex challenges in behavior and learning. Autism has been linked to differences in how the brain’s neurons communicate and process information.

Research shows that people with autism often have unstable blood vessels in the brain. This can interfere with blood flow. Other studies suggest excessive growth of blood vessels in people with autism. When brain cells aren’t functioning properly, the brain may try to compensate by increasing blood flow, which could lead to more severe autism symptoms. All this research points to the importance of focusing on brain and cellular  health when managing autism.

Here are some key nutrients that are great for individuals with autism.

Key Nutrients to Support Brain Health in Autism

Nutrition is important for brain health, especially in autism. Certain nutrients can support better brain function and reduce inflammation. Let’s look at the key vitamins and minerals and how they can help with autism. 

1. Omega-3 Fatty Acids

Omega-3 fatty acids are important for brain health. They help build brain cells, reduce inflammation, and improve communication between neurons. They also improve mood, sleep, and attention, common symptoms in autism. Research suggests that people with autism may have lower levels of omega-3s, which can affect brain function and behavior. Eating foods like fatty fish, flaxseeds, and chia seeds, or taking a fish oil supplement, can boost omega-3 levels and support brain health.

2. Vitamin D

Vitamin D is famous for supporting bone health, but it’s also key for brain function. It helps regulate the immune system and supports neurotransmitters, which are important for mood and cognitive development. 

A Chinese study that was published in Nutrition and Dietary Supplements in 2024 found that low vitamin D levels may worsen autism symptoms. The researchers also found that supplementing with vitamin D improves autism symptoms.  Hence, getting enough through sunlight, fortified foods, or supplements is important for brain health.

Emerging research shows that combining omega-3 with vitamin D may improve cognitive function and brain health, as highlighted in Omega-3 with Vitamin D by Performance Lab, which details five key benefits, including immune support, bone strength, and heart health.

3. B Vitamins

B vitamins, especially B6 and B12, are crucial for brain function and energy production. They play a role in making neurotransmitters that impact mood, memory, and behavior. For people with autism, keeping B vitamin levels balanced can improve focus, reduce irritability, and boost mental clarity. You can find these vitamins in leafy greens, eggs, and poultry, but supplements can help if you’re not getting enough through food.

4. Magnesium

Magnesium is a vital mineral involved in over 300 reactions in the body, including those that affect mood and brain function. Research suggests that people with autism might be more likely to have magnesium deficiencies, which can lead to anxiety, irritability, and trouble focusing. Adding magnesium-rich foods like spinach, almonds, and black beans to the diet, or using a supplement, can help improve brain health and reduce these symptoms.

Can NMN Help With Autism?

In addition to these key nutrients, there are specialized supplements that can provide targeted support for brain health in individuals with autism. One such supplement is NMN (Nicotinamide Mononucleotide), which has gained popularity recently for its anti-aging benefits. Recent research suggests that NMN supplements may also alleviate some of the symptoms of autism such as social deficits.

NMN Supplements for Cellular Health

NMN helps the body produce NAD+ (Nicotinamide Adenine Dinucleotide), which is vital for energy production, DNA repair, and brain health. As we get older, NAD+ levels decrease, leading to issues with memory, energy, and cell function. For individuals with autism, NMN supplements might improve brain function by boosting energy in cells and protecting brain health in the long run. When choosing NMN supplements for cellular health, it’s essential to look for a high-quality product that offers effective dosages and is free from unnecessary fillers.

Can a Keto Diet Help With Autism?

Research suggests that a ketogenic (keto) diet, which is high in fats and low in carbohydrates, may help improve brain function in individuals with autism. This diet alters how the brain uses energy, potentially reducing inflammation and supporting better communication between neurons. While early studies show promise, more research is needed to fully understand the keto diet’s long-term effects on autism symptoms.

Other Dietary Strategies That Might Support Brain Health in Autism

• Gluten-free, Casein-free Diet: Cutting out gluten (wheat) and casein (dairy) may improve behavior and digestion in some people with autism.
• Probiotic Foods: Adding foods like yogurt and fermented veggies can support gut health, which may help with brain function.
• Low Sugar Diet: Reducing sugary foods may help with mood swings and hyperactivity.
• Antioxidant Foods: Berries and leafy greens can protect brain cells and improve brain health.

Conclusion

The right diet can help support brain health for people with autism. Omega-3s, probiotics, and vitamins all play a part in improving focus and mood. NMN supplements for cellular health may also help by boosting energy and protecting brain function. At the end of the day, it’s all about finding the right balance to support the cognitive needs of the individual living with autism.
