Hello archus I hope you are feeling better,what type of soup was it and what type of ingredients were in it?Everything that comes in a can is poor quality as far as feeding the body in an optimal fashion.So you went from high grade to low grade and felt the differance.Once you run the body clean you cant go back unless your willing to suffer your way there.The issue of B12 and the fact that most people on a vegan diet will eventually run into it is a simple truth that some people have issues with.For an indepth article on this subject visit treeoflife.nu and go to the articles section.Dr. Gabriel Cousens is one of the most qualified individuals to speak on this highly debated subject.B12 is found in the plant kingdom and algae has high amounts of B12.Unfortunatly the B12 analogs compete with the human grade B12 and that makes it a poor source of human grade B12.The best B12 is harvested from bacteria but this source is expensive but well worth the money.Have you tried making some smoothies with your goji berries yet?And did you get any of the goji powder or goji bliss.Talk to you later,Jeff.
