This could be in TMI category but I have irritable bowel syndrome (IBS). This has been an issue for me as long as I can remember. I recently have learned an awful lot about probiotics. I am going to share my journey with you.
This is what I am currently taking. It costs $55 for two months. It has 50 billion live bacteria and 10 different bacteria strains. It includes both Lactobacillus and Bifido strains. It is awesome. It has helped my issues but not dissolved them. I recommend this to anyone. Healthy gut flora can help your mood, weight, energy, EVERYTHING. If you don't take probiotics, you should!
Last, but not least, EAT YOGURT! There are also probiotics in yogurt. I eat yogurt 3 days a week at least.
