Which tryptophan should be used in a 12-year-old with ASD, sleep problems and taking Fluoxetine?

Tryptophan supplementation may be beneficial in the treatment of sleep disorders, especially in the context of problems with falling asleep and waking up at night. Tryptophan is an essential amino acid that supports the production of serotonin and melatonin, which can help regulate sleep.

In the case of a child with ADHD taking fluoxetine, it is important to consult a doctor about supplementation, as both agents affect serotonin levels, which increases the risk of serotonin syndrome. Before introducing tryptophan, you should consult with your treating physician to assess safety and potential interactions. Alternatively, it is worth discussing other methods of sleep support, e.g. melatonin, which is sometimes used in children with ASD under the supervision of a specialist.

It is best to give tryptophan in the evening, in combination with a meal rich in vitamin B6 and magnesium, which increases its bioavailability. You should also monitor your body's response to supplementation to adjust the dose to your child's individual needs.
