How do you extract the spermidine? What is the extraction process?

Our company uses a unique water-only extraction process. There are no hard chemicals or synthetic solvents used in our extraction. We do not disclose the details about the specifics, since this special process was developed over many years by researchers at the Karl-Franzens-University in Graz, Austria in close cooperation with experts from our company. What I can confirm is that water is the only solvent we use.
