What Sweetener To Add To MMS1 For Bad Taste

I know that SweetLeaf Stevia Clear has been recommended to add to MMS1 if the taste is bad but it is 4 times as expensive in my country as a local brand. I will be using Citric Acid as an activator and have been told that MMS doesn't taste good activated with HCl and even worse with CA.
Our local brand's ( Stevia Liquid 150ml ) ingredients are as follows:

- Purified water
- steviol extract (95% steviol glycosides) (non-nutritive sweetener)
- potassium sorbate
- citric acid

Will this be OK to add to MMS1 and CDS mixed with water?

Thanks
