  • Toxic Heavy Metals Causing ADHD, Autism and Learning

    Heavy metals like arsenic, lead, copper and mercury mainly effect reproductive system and are especially toxic to the growing foetus. These heavy metals are not filtered by the placenta and move from mother to child and can directly deposit in growing foetal tissue. Thus, the unborn child receives heavy metals from their pregnant mother.
