I asked him (my son) to rate the product, & he says he would give it 4 stars! Thank you so much for making this product & please continue to do so - as I would like to continue my son on them for about a year (if ideal), as I am trying to re-set & be consistent with his immune system. Thank you again, & we hope to continue to see improvement with my son's immune system (& his response to allergies) while on this supplement.
