Hello Pete, and anyone else that reads this. Often times we are skeptic due to us going by what we hear rather than what we know. If you do some research there are tons of scientific evidence proving the contents of the seabuckthorn berry. Don't go by just the company site, broaden your search. www.pubmed.com a huge site dedicated to medical research. Also go to www.seabuckthorn.com this has nothing to due with the Sibu company. Its research dedicated to the seabuckthorn berry, which has been around for centuries. Also as far as scientific evidence, in a medical documentary called the SibuYidian there are more than 130 chapters dedicated to the research of the Seabuckthorn berry. I could go on. Once again people can say what they will, but this will not stop me from helping people better their lives. I was an apprentice to a very good Mortician and have done my studies on health also. So slam all you want. I will be happy to help those who desire the help. The rest of you good luck and happy hunting.
