I can understand your concern.
You need not worry if there are same salts in both.
What matters is the salt. Trade names do not matter. Its the salts which do all the work.
Its ok if you have gone for tge same salt which is cheaper.
Just do not forget to mention once to the gastroenterologist next time.
