I’ll say neigh to this, looks like way too much potassium (like 10x more than needed) compared to sodium.
This looks primarily like a mix of Sodium Chloride + potassium Chloride.
Sodium chloride is table salt, and you can find potassium chloride in ‘low sodium salt’ (at least in the USA).
I would look at trying to find some sodium citrate powder and go with that, my current take after making overcomplicated DIY electrolytes is that sodium is all that likely matters, at least for the vast majority of situations.
Edit: Here is a discussion of how to tell if you are getting enough sodium:
@Dr_Alex_Harrison has a lot of posts on the forums regarding electrolytes as well as carb intake in drinks. Lots of good information there.
