We buy our Ampelopsin exclusively from one of the largest suppliers of natural extract products in the world who are based in China, and have offices in Europe and the US. We’ve worked with them for years, and their product has always tested extraordinarily well. The certificate of analysis (or dihydromyricetin COA) provided below is from our latest order (January ’19) and shows very high levels of purity, and a dry product that is free from heavy metals, toxins, and bacteria.
