In the case of the MCT they use - the coconut oil originates from Indonesia and Malaysia and is processed into MCT powder in China - so no trained Thai monkeys were harmed or oppressed in the manufacture of it.
We don’t condone using monkeys to harvest coconuts. We have statements against the use of monkeys as part of our quality control procedure. The Vegan Society checks all of our ingredient specifications and query where they have any concerns. We haven’t been questioned about any of our current ingredients.
