How can I help improve my son's concentration?

[Guest guest]

My six year old son is having a lot of trouble with his concentration

at school and I was wondering if anyone knows of any natural

supplements that may help him.

He eats a healthy diet, never misses breakfast, does not have ADD

or ADHD, or any other behavioural problems.

Blood tests did not reveal any abnormalities and I do nightly

meditations with him especially aimed at children.

Any advice will be much appreciated.

Thank you.

Valerie.
