Choosing the Best Probiotics for Autism

Autism researchers believe there is a strong link between the functioning of the brain and the gut. They claim that several types of diets and probiotics for autism can help manage the symptoms.

With the very large number of foods and recommended diets out there, how can you determine what works best for all family members with autism?

What are probiotics?

Probiotics are live microorganisms, often referred to as “good” bacteria, known to aid digestion, boost the immune system, and improve gastrointestinal problems.

Probiotics can be found in foods such as yogurt, kefir, sauerkraut, kimchi, and miso, and are readily available in dietary supplements.

The connection between autism, probiotics, and digestive health

Researchers consider an unhealthy gut to be a causative factor of autism and ADHD. Clinical studies show that people with autism often have abnormal digestive health conditions such as Irritable Bowel Syndrome (IBS).

A study of children with autism spectrum disorders showed an elevated number of pathogenic bacteria called Clostridia, which are known to cause GI problems.

A separate study showed children with ASD have a low amount of healthy species of bacteria called Faecalibacterium prausnitzii, which is associated with a healthy digestive system.

To achieve a healthy digestive tract, the thousands of strains of beneficial bacteria should live in balance with the “bad bacteria.”

Experts suggest that diet may alleviate this problem. Research has shown that probiotic microbes have positive effects on the digestive and gastrointestinal health of both adults and children.

Probiotic supplements and food products may treat autism and attention deficit hyperactivity disorder (ADHD).

Gut bacteria and autism treatment

For years, experts have recognized a strong link between the gut and the brain, often referred to as the gut-brain connection.

Many believe that the balance of bacteria in the digestive system, known as the gut microbiota, may play a key role in a child’s development after birth.

Some researchers suspect that an imbalance between healthy and unhealthy gut bacteria might contribute to certain behaviors or symptoms seen in children with autism.

While more studies are still underway, early findings suggest that the chemicals produced by bacteria in the digestive system may influence mood, behavior, and even how children with autism respond to the world around them.

Parents and professionals are becoming increasingly interested in how supporting gut health might help improve well-being in children on the spectrum.

Though this area of research is still developing, it highlights the importance of looking at autism through a whole-body lens, not just the brain.

What causes gastrointestinal problems in people with autism?

In their study on autism, researchers led by Dr. Paul Ashwood of the University of California’s Davis MIND (Medical Investigation of Neurodevelopmental Disorders) Institute identified proofs linking autism with changes in the brain, gastrointestinal (GI) distress, immune dysfunction, and severe repetitive behaviors associated with autism spectrum disorders.

Researchers found that children with autism have elevated levels of dendritic cells. These cells are the ‘generals’ of the immune system. Ashwood said the dendritic cells serve a key role in the body’s immune response to microorganisms, including disease-causing germs and normal digestive bacteria.

What are the best probiotics for kids with autism?

Many children with ASD suffer from gastrointestinal issues and some form of IBS. It is recommended that they consume foods with soluble fiber to effectively reduce their symptoms or treat them completely.

But how do you choose the best probiotic for autism? Two of the most recommended probiotic strains for autism and IBS are Lactobacillus reuteri and Bifidobacterium. 

These can be useful tools in addition to incorporating whole probiotic-rich foods into your autistic child’s diet.

Over the past decade, studies on specific probiotic strains have been conducted to confirm the gut-brain theory and determine whether these strains are effective and safe for treating symptoms of autism.

Lactobacillus reuteri for autism

Lactobacillus reuteri is a bacteria strain commonly found in autism probiotics treatment.

While most probiotics improve gut problems, Lactobacillus reuteri has also been observed to improve social behavior in autism.

L. reuteri has been linked to increased levels of oxytocin, often called the “love hormone,” which plays a role in bonding and social connection.

For children with autism, having this type of bacteria in the gut may help improve emotional well-being and social interaction.

While results can vary from child to child, supporting a healthy gut microbiome is becoming an area of growing interest for many families and professionals.

B. fragilis strain and autism

Studies show that Bacteroides fragilis, also known as B. fragilis, may be helpful to children with autism.

Research has discovered that B. fragilis has a unique ability to penetrate even the most hostile mucus layers and embed itself into the intestine’s cells.

Some studies have shown that the bacteria Bacteroides fragilis may help improve gut health by repairing a “leaky gut,” which is when the digestive system becomes more permeable than it should be.

In experiments, this improvement was linked to reduced anxiety, less obsessive behavior, and increased communication, behaviors often seen in children with autism.

However, it’s important to know that B. fragilis is not currently available as a treatment, and more research is needed before it can be recommended for use in children.

Is it safe for kids to take probiotics?

Probiotics are not regulated by the US Food and Drug Administration (FDA) because they are regulated as a food product.

Doctors and health experts agree probiotics are generally safe for both children and adults. However, children with weak immune systems or serious illnesses may not be able to take probiotics due to possible harmful effects.

The amount and composition of live bacteria present in probiotic food products should also be considered. Parents should always consult a child’s doctor before starting probiotic supplements.

Potential side effects of using probiotics for autism

While considered safe, ingesting live microorganisms may have some side effects.

Side effects of probiotics may include:

• Mild gas
• Bloating
• Overstimulated immune system
• Constipation
• Increased thirst
• May trigger allergies
• Headaches

Individuals with a weak immune system, who are seriously ill or suffering from certain bowel problems, are advised to seek a doctor’s approval before consuming probiotics.

Live microorganisms are also not suitable for infants, young children, and pregnant women.

Never give probiotics to premature infants. For patients with bloody stools, post-cardiac surgery patients, and patients with pancreatic dysfunction, the use should be authorized by their physicians.

Are probiotics the right choice for your autistic child?

Managing your child’s health can feel overwhelming, especially with the many factors that influence autism. Autism is complex, and every child’s needs are unique.

While probiotics and new insights into the gut microbiome offer promising possibilities, they are just one part of a much bigger picture.

These advances represent hopeful progress toward better support and treatments. However, it’s essential to collaborate closely with healthcare professionals to determine the most suitable approach for your child’s journey.

FAQs

Q: What are the best probiotics for an autistic child?

A: The best probiotics for an autistic child typically include strains like Lactobacillus and Bifidobacterium, which support gut health and reduce inflammation. However, it’s important to consult a healthcare professional to choose a probiotic tailored to the child’s specific needs.

Q: How to heal an autistic child’s gut?

A: Healing an autistic child’s gut often involves a combination of dietary changes, probiotics, and reducing exposure to inflammatory foods or toxins. Working with a healthcare provider to develop a personalized plan is essential for effective gut health restoration.

Q: What is the best supplement for an autistic child?

A: Commonly recommended supplements for autistic children include omega-3 fatty acids, vitamin D, and probiotics to support brain and gut health. Supplement needs vary individually, so professional guidance is important to determine the best options.

Q: What gut bacteria are missing in autism?

A: Studies suggest that children with autism often have lower levels of beneficial bacteria such as Bifidobacterium and Prevotella. This imbalance may contribute to digestive issues and inflammation seen in some autistic individuals.
