I did a search on coconut aminos and there is a product called Coconut Aminos. It is made from the aged sap of the coconut palm, with added sea salt.. However, the sap is sweet, and 1tsp is 1g carb, which is a bit high for me, as I tend to throw stuff like that around too generously. It does, however, state that it is "enzymatically alive", which is interesting, as the more enzymes we can get into us, hopefully the better for our general health.
