Maybe you could switch to a broccoli sprout powder to increase pH, eg 1/4 tsp twice a day. Even the old Sodium phos and Potassium phos salts will buffer acid. HealthBusters
I was using 1-2 tsp a day of bi-carb soda to bring up my PH balance. (Disease thrives in acidic environment)
Something made send email of a well known brand sold in supermarket and asked for the ingredients of their bi-carb.
After prolonged carryon they admitted it had aluminium in it.
Imagine that. I bet not many people would know that.
Manufacturers thrive on our ignorance.
