This is fabulous and very nutritious for run-down animals and anyone needing a boost of goodness. This is seaweed, dried kelp, slow simmered for a whole so all the nutrients are released. It is simple and easy to make and very good for everyone.
The kelp can be found in the grocery stores in the Asian section usually. Nothing else is to be added, it is just plain seaweed/kelp as shown in the photo above and below.
