Yes I agree as well. I made the most ridiculous comment about my observation of Citrate not being a good reducing agent/stabilizer, but now I realized its just much slower than cinnamon extract. I have noticed the cinnamon extract alone seems to only partially reduce. I think this is because of the pH not quite being in the reducing range. While citrate acts as a buffer/reducer/stabilizer, cinnamon I believe is lacking in this buffer factor
