I read that there is a probiotic from the brand bio k for IBS with a tendency for diarrhea: do you think this would be a good option?

It is always important to consult with a healthcare professional before starting any new supplement or medication, especially if you are unsure about its effectiveness. Keeping a journal of your symptoms, diet, activities, and mood can be helpful in identifying possible triggers for your symptoms. If the symptoms persist or worsen, it is advisable to seek medical advice for a thorough evaluation. Stress and anxiety can also play a role in digestive issues, so it may be beneficial to address these factors as well.
