I have never heard of it. It looks good, it does have Beet Pulp in it which is just a cheap filler, it is a controversial ingredient though and foods like Life's Abundance, Holistic Select have it in their foods as well.. I think its more of a personal preference really. Some people have real issues with garlic for example and that something I really don't have an issue with.
Here is a link if anyone wants to look.
