Any specific multivitamins for a autistic child. (6+ years)

A. Zincovit you can give to twice in a day or one time in the day if you’re giving one time then you can give 5ML to your child along with that since your child is autistic I would suggest you to shift to gluten-free diet for the time being and also would strongly recommend you to take a homeopathic treatment for your child or Ayurvedic but I personally believe homoeopathic is better
