I have given my son who has dyslexia and ADHD 1/2 Livolin Forte which has phosphatidyl choline in desperation and surprisingly he has immense changes to his reading ability, cos at age 10 he couldnt read, and he will struggle to spell, but now after barely 1 week on livolin, he has the ability to grasp the phonetic sound some 40% of the words shown to him on sight. Can anyone tell me if it is harmful for him to take that supplement? I have been giving him fish oil but there is not much changes. I check into the internet which say phosphatidyl is helpful for brain problem like alzheimer and dementia. But I will like to share what I had learned so as to help other desperate parents.
