Autism (autism spectrum disorder, ASD) refers to a complex group of neurodevelopmental disorders that affect social behaviour, communication and interaction with the environment. According to the latest official data from the CDC (Centres for Disease Control and Prevention), the prevalence of ASD is approximately 1 in 36 children aged 8, with a higher prevalence among boys than girls. This trend towards increasing diagnoses reflects not only better identification of symptoms but also greater awareness of the diverse manifestations of autism across the population.

There is a growing body of research in the scientific literature examining biochemical and neurophysiological differences in individuals with ASD. These studies suggest that oxidative stress, dysregulation of immune responses and neurotransmitter imbalances may play a role in some individuals. From this perspective, attention is also beginning to be paid to supporting endogenous mechanisms that may influence cellular functions and neuroprotection, and carnosine is among the dietary supplements being investigated in this field.
There are many myths surrounding supplements for ASD. A common misconception is that dietary supplements can ‘cure’ autism or significantly alter its core characteristics. Such claims are not supported by high-quality clinical evidence. Autism, as a spectrum of neurological manifestations, is the result of a complex interaction between genetic and environmental factors, and there is no single supplement that can eliminate it. However, scientific studies show that certain substances may have a beneficial effect on accompanying symptoms or on overall brain function, which can improve quality of life.
Carnosine is a dipeptide found in brain tissue and muscles; it is being studied for its ability to act as an antioxidant, a modulator of neurotransmission and a stabiliser of cellular homeostasis. Although research into ASD is not as extensive as that on sulforaphane, for example, the existing evidence suggests potential benefits. Pilot clinical trials from the 1990s and subsequent reports (e.g. results published in the Journal of Autism and Developmental Disorders) observed modest improvements in language skills, social interaction and behavioural manifestations in a small number of children with ASD following carnosine supplementation. However, these results remain preliminary and require confirmation in larger randomised clinical trials. Current data suggest that carnosine may serve as a complementary support which, alongside comprehensive therapeutic care, contributes to overall optimal brain function, rather than as a standalone treatment for autism.
In the context of the latest clinical reviews, it also appears that antioxidants, substances that influence oxidative stress metabolism, and neuroprotective mechanisms may improve overall well-being, sleep or the ability to concentrate in some individuals with ASD, although the effects are variable and individual. Although the specific mechanisms are not fully understood, it is thought that supporting redox balance and reducing oxidative stress may have a positive impact on the nervous system.

For families and individuals with ASD, it is important to take a pragmatic and comprehensive approach to supporting brain health. In addition to specialist behavioural and educational therapies, a balanced diet rich in antioxidants, healthy fats and micronutrients that support neurological function can be beneficial. Physical activity is one of the factors proven to support mood, sleep and cognitive processes, and regular exercise should be part of the daily routine, health permitting. In children with ASD, it is also beneficial to monitor nutritional status and, if vitamin or mineral deficiencies are suspected, to consult a specialist about supplementation.
For adults with ASD, it is recommended to focus not only on physical health but also on social and psychological aspects – support groups, stress management techniques, mindfulness and therapy focused on social skills can significantly contribute to improving quality of life.
In summary, Carnosine EXTRA represents a supplementary, science-backed option that may contribute to the care of brain cells and support optimal nervous system function, but it should not be regarded as the sole ‘cure’ for autism. Its use, particularly in combination with interdisciplinary care, can form part of an individually tailored approach that takes into account the specific characteristics of each person with ASD.
