Diet and Nutrition

Supporting Autism Through Diet and Natural Supplements

Diet and nutrition can play an important role in the emotional, physical, and even spiritual wellbeing of individuals on the autistic spectrum. While no single diet is a cure, many families have explored dietary changes and supplements to help manage certain behaviours, improve sleep, reduce anxiety, and support learning and development.

This page explores some of the most commonly discussed nutritional strategies, alongside important considerations and professional guidance.


Before You Begin

Before making any changes to diet or adding supplements, it’s vital to consult with a qualified nutritional therapist, GP, or registered healthcare professional. Supplements can interact with other medications or conditions, and each person’s needs are unique.

The information here is based on personal experience, collaborative work with health professionals, and university-level research, including a Master’s degree assignment entitled “Using Nutritional Supplements for the Management of Autism.”


Commonly Explored Dietary Interventions

Gluten-Free, Casein-Free (GFCF) Diet

  • This diet removes gluten (found in wheat, rye, barley) and casein (found in dairy) from the individual’s meals.
  • Some families report improvements in attention, behaviour, digestion, and mood.
  • It is thought that in some autistic individuals, these proteins are not broken down properly and may affect brain function or cause discomfort.

Vitamin B6 and Magnesium

  • B6 is involved in neurotransmitter production, and magnesium helps regulate mood, sleep, and stress.
  • Together, they have been explored to reduce hyperactivity and improve focus or emotional regulation.
  • Dosage must always be guided by a professional to avoid toxicity or imbalances.

Vitamin B12

  • Especially important for nervous system health, B12 is sometimes trialled to support energy levels, focus, and general wellbeing.

Valerian

  • A natural herb used to promote relaxation and improve sleep quality.
  • Particularly helpful when anxiety or poor sleep patterns are present.

Holistic Support: Flower and Herbal Remedies

In addition to dietary changes, flower essences and herbal remedies such as Bach Flower Remedies are sometimes used to support emotional balance. These can be integrated into a broader wellness plan that includes mindfulness, energy therapies, and emotional coaching.


Useful Resources

While specific books were recommended on the original website, it is best to explore reputable, up-to-date sources or consult directly with qualified nutritional therapists who specialise in autism support.


Key Considerations

  • Always personalise dietary approaches: what works for one individual may not work for another.
  • Observe and record changes over time (keep a food and behaviour diary).
  • Consider food sensitivities, gut health, and co-occurring conditions such as ADHD or sensory issues.
  • Nutrition is one part of a whole-person approach. It is not a substitute for therapies, education support, or communication strategies.

Ongoing Study and Support

This site’s practitioner is currently training as a Nutritional Therapist to add formal qualification to years of research and lived experience. Nutritional support will soon become part of the holistic, person- and family-centred services offered.

If you would like support exploring dietary strategies for your autistic child or loved one, consultations can be arranged as part of your wider support plan.
