This is dairy free and SCD legal.
However, it doesn't have a hechsher.
We had consulted with Rabbi Zushe Blech a"h, former chief Rabbi of Earth Kosher, and he said: I am sure that it Kosher halachically - I take no position on any dairy status.
In other words - since the product grows on strains of dairy, it's questionable on the dairy/parve aspect, so it should be used with dairy dishes etc.
