Allison, I have not given jiaogulan before but, from my reading here, I think it is dosed by what is required to get an increase in gum color.  That would be indicative of increased blood flow.  It’s possible though that you were told differently for a reason.
As they explain on the joint supplement web page, chondroitin is the most expensive ingredient and most crucial for repair.  If you began using that in concert with the other things Dr. Kellon listed then it seems like you could try decreasing the chondroitin as his recovery shows obvious progress.
