Biotin
​
What is Biotin?
Biotin, also known as Vitamin B7, is a water-soluble B-vitamin essential for various metabolic functions, including energy production, fatty acid synthesis, and the metabolism of amino acids. It also plays a role in maintaining healthy skin, hair, and nails.
​
Biotin and Nervous System Health
-
Biotin supports the function of enzymes that regulate metabolic pathways in the brain.
-
It contributes to myelin sheath formation, which is essential for proper nerve signal transmission.
-
Deficiency in biotin can lead to neurological symptoms such as lethargy, hypotonia (reduced muscle tone), and developmental delays.
​
Effects on Autism
-
Deficiency in Autism:
-
Children with autism may have compromised gut health, which can impact biotin synthesis by gut bacteria.
-
Poor dietary intake or metabolic disorders can lead to low biotin levels, exacerbating symptoms like irritability, cognitive impairment, or skin issues.
-
-
Potential Benefits:
-
Biotin supplementation has been suggested to improve energy metabolism and support brain health.
-
Some reports indicate improvements in attention span, cognitive function, and energy levels in children with autism, though more research is needed.

​
Testing for Biotin Deficiency
-
Symptoms of Deficiency:
-
Hair thinning or loss.
-
Skin rashes, particularly around the face.
-
Neurological symptoms, such as fatigue, depression, or developmental delays.
-
-
Diagnostic Testing:
-
Serum biotin levels can be assessed through blood tests.
-
Monitoring symptoms and dietary intake can also help evaluate deficiency risks.
-
​
Food Sources of Biotin (Highest on Top):
-
Egg yolks (cooked).
-
Liver and organ meats.
-
Salmon.
-
Avocados.
-
Nuts and seeds (e.g., almonds, sunflower seeds).
-
Sweet potatoes.
-
Whole grains.
-
Dairy products like cheese and milk.
-
Mushrooms.
​
Supplementation for Children with Autism
-
Dosage:
-
Recommended daily intake for children:
-
Infants: 5–6 mcg/day.
-
Ages 1–3: 8 mcg/day.
-
Ages 4–8: 12 mcg/day.
-
Ages 9–13: 20 mcg/day.
-
-
For therapeutic use in autism, doses up to 10–20 mg/day may be used under supervision.
-
-
Forms of Biotin:
-
Capsules, tablets, or powders.
-
Often included in multivitamins or B-complex supplements.
-
​
Biotin and Heavy Metal Detoxification
-
Biotin plays a role in detoxification by supporting metabolic pathways that process and eliminate toxins.
-
It may help manage oxidative stress caused by heavy metals like lead and mercury, which can exacerbate autism symptoms.
​
Key Takeaways
-
Essential for Brain Health: Biotin supports nerve function, energy metabolism, and detoxification, which are critical in managing autism-related challenges.
-
Deficiency Risks: Children with autism may be at a higher risk of biotin deficiency due to gut health issues or restricted diets.
-
Food and Supplementation: Biotin-rich foods and supplements can help support neurological and metabolic health.
-
Dosage and Safety: While standard dosages are low, higher therapeutic doses can be used under a doctor's guidance to address specific autism-related needs.
