Zinc

 

What is Zinc?

Zinc is an essential mineral that plays a critical role in many bodily functions, including immune system health, protein synthesis, cell growth, and wound healing. It also has a vital role in neurological function and is crucial for brain development and function.

 

 

Effects on Autism

Research shows that children with autism spectrum disorder (ASD) often have lower levels of zinc compared to neurotypical children. Zinc is necessary for the functioning of many enzymes in the body, including those involved in neurotransmitter regulation and DNA synthesis.
 

Zinc has been found to:

  • Support cognitive development and may improve memory, attention, and focus.

  • Improve behavior and mood, which can help reduce irritability and impulsivity in children with autism.

  • Enhance social interactions and reduce anxiety, which are often challenges for children with autism.

  • Promote better sleep by regulating melatonin production.

     

Zinc Deficiency and Autism

A zinc deficiency can lead to:

  • Immune system dysfunction, increasing susceptibility to infections.

  • Delayed development, including issues with speech and language.

  • Cognitive difficulties such as poor memory, trouble concentrating, and difficulty with learning.

  • Behavioral problems, such as irritability, hyperactivity, and aggression.

  • Skin conditions, including eczema, rashes, and slow wound healing.
     

Children with autism may have an increased risk of zinc deficiency due to dietary restrictions or absorption issues, making supplementation important in some cases.

 

Forms of Zinc in Supplements

Zinc is available in various supplement forms, including:

  1. Zinc Gluconate: A common and well-absorbed form of zinc, often found in over-the-counter supplements.

  2. Zinc Citrate: Another highly bioavailable form, commonly used in supplements.

  3. Zinc Picolinate: Known for its superior absorption and effectiveness, often recommended for those with digestive issues.

  4. Zinc Oxide: A less expensive form of zinc but may not be absorbed as well as other types.

  5. Zinc Bisglycinate: A chelated form of zinc, which is known to be gentle on the stomach and well-absorbed.

     

Dosage Information for Children with Autism

For children with autism, zinc supplementation should be based on age and specific needs, and it’s important to work with a healthcare provider to determine the right dose.

Common recommended dosages include:

  • Children 1-3 years old: 2-5 mg of zinc per day.

  • Children 4-8 years old: 5-10 mg of zinc per day.

  • Children 9-13 years old: 8-12 mg of zinc per day.

  • Teenagers (14-18 years old): 11-15 mg of zinc per day.
     

It’s essential to monitor zinc intake to avoid exceeding the tolerable upper intake level (40 mg/day for children 1-3 years old and 40 mg/day for older children), as too much zinc can interfere with copper absorption and lead to a deficiency in copper.

 

Effects on Heavy Metal Toxicity

Zinc supplementation may also help reduce the impact of heavy metal toxicity in children with autism. Zinc is known to support the body’s ability to detoxify heavy metals, such as lead, mercury, and cadmium. Zinc works by:

  • Blocking the absorption of toxic metals like lead and mercury in the digestive tract.

  • Helping to repair damage caused by heavy metals and support the detoxification process.

  • Reducing inflammation caused by heavy metal exposure, which is often seen in children with autism.

     

Zinc and Copper Ratio

It’s important to note that the zinc/copper ratio plays a significant role in maintaining neurological health and managing autism symptoms. A high zinc/copper ratio supports optimal brain development and reduces inflammation.

Since children with autism often have high copper and low zinc levels, maintaining a balanced ratio is essential for:

  • Brain function

  • Reduced inflammation

  • Cognitive development
     

For more detailed information on the zinc/copper ratio and its effects on children with autism, please refer to the section on Zinc and Copper Ratio.

 

Key Takeaways

  • Zinc plays an essential role in the development and health of children with autism. 

  • Supplementing with zinc may help improve cognitive function, mood, and behavior, and may also reduce symptoms of heavy metal toxicity. 

  • Zinc supplementation should be approached with care, considering age-appropriate dosages and monitoring for any potential imbalances with copper.

  •  Always consult a healthcare provider before beginning supplementation to ensure the appropriate approach for your child’s specific needs.
