Children on the Autism Spectrum exhibit a wide range of behavioural issues. Here I have listed some of the more common behavioural traits, what may be causing them and how they can be managed. This is not a complete list, if there is a behavioural issue that you are trying to deal with that is not listed, email me and I will endeavour to sort it out.
Please consult a practitioner familiar with supplementing ASD children. There are appropriate dosages that need to be determined, or co-factors than may need to be added. Some children may regress on a supplement, an experienced practitioner will know whether this is transient or a negative reaction to the supplement.
