In what way do you notice it, Kim, if you don't mind me asking? S xI've tried several brands and always come back to Charlotte's Web. It's been independently tested and featured on 60 minutes and other programs and radio shows. It cured a little girl (Charlotte) who was having hundreds of seizures a day and gained national attention.
I know lots of PALS taking this and others.
It isn't cheap but, if I skip a few days, I notice it.
