Hi Kate
I've been taking this protocol for 4 months with slight alterations. My neurologist recommended Acetyl L Carnatine and Alpha Lipoic Acid but, only when I asked him. Never offered it up as a suggestion prior. I think its worked well overall. It's no game changer for me pain wise but always hoping it's having a positive effect. Another good possibility to add may be Turmeric. Good luck if you decide to try it for your son and might want to run it by his Dr. first. Take care.
