Protectis for 5 year old. Of protectis?

Help. My daughter is 5 yrs old. 21 kgs weight. She has had multiple cases of stomach pain on a daily basis for a couple of years. Last Nov I stopped all meds for her and on the advise of a gastroenterologist stated giving her the protectis probiotics chewable tablet once in the morning and once in the evening. Post this, she has had very less tummy pain and digestion issues and does not struggle with stomach issues. Since it's been 6 months, I have stopped the morning tabof protectis and am giving it to her only in the night. Although she hasn't complained of stomach pain, she seems to be passing a lot of gas, especially in the night. It does not smell most times but sometimes it does. She's not on dairy . Only home cooked meals by me. Eats a banana everyday. Is the increase in gas due to stopping of one dose of protectis? Can I start this and can it be given for long durations. What could be the cause. We have done x rays, usg, blood tests in Nov, all came out normal. Pl advise.
