Nutritional supplements and vitamins may be helpful in reducing some symptoms of autism especially in situations where a child has some underlying nutritional deficiency. In this regard, it is only relevant to state that vitamins do not treat autism. Moreover, every child with autism is a unique person and the effectiveness of supplements may differ greatly in one child and another. There are a number of vitamins and other supplements that may offer some potential benefits when taken in moderation and under the supervision of a physician.
Vitamin B6 is also used with magnesium and is found to enhance communication, attention and behavior of children with autism. Likewise, Vitamin D is often deficient in the individuals on the autism spectrum, and taking it in supplements can help to maintain the health of the brain, mood, as well as immune systems. The Omega-3 fatty acids, which are widely present in fish oil are also used extensively because of their known effects of brain development and behavior. Research indicates also that omega-3s can reduce hyperactivity as well as enhance eye contact.
Now gut health. Gut health is defined as the health of the gastrointestinal system (GI system), such as the stomach, the intestines, and the colon and its microorganisms, as a collective called the gut microbiome. It includes the roles of breaking down food, nutrient absorption and excretion of waste. The overall health is also dependent on a healthy gut microbiome, which affects the digestive system, immunity, and even affect the mental state.
A lot of autistic people have digestive problems and probiotics can assist in re-establishing a normal balance of gut bacteria and this may in effect impact the mood and behavior. Multivitamins may also be useful particularly among children who are picky eaters and who may not be able to access a balanced diet. Furthermore, some genetic mutations such as the MTHFR mutation, which influences the body to process folic acid, might also respond to folate and folic acid-related mutations, particularly in the form of methylfolate.
It is better to consult specialists, such as pediatricians, nutritionists, or autism specialists, before introducing some vitamins or supplements. The medical advice is made to make sure that supplements are safe, suitable, and specific to the needs of the child. Vitamins may be included as a holistic approach to the support of autistic children when used wisely and in conjunction with some evidence-based therapies, including speech, occupational, and behavioral therapy.
