As long as it doesn’t have like wood splinters (idk why it would) or come from something with toxins in or on it then idk why it would be harmful for you at all. You just can’t digest it. It’s no worse than eating a bunch of corn and pooping out the shell from the kernels
sawdust isn’t just cellulose though, idk how they source food grade cellulose as an additive but it’d be more like ground up straw or something. Wood sawdust is full of lignin
