This topic is about exploring the potential benefits of probiotics and prebiotics for individuals who have undergone an ileostomy, a procedure where the colon is removed. The question arises because the colon is typically where many beneficial bacteria reside. Here are some insights and advice shared by others on this topic:

1. **Ineffectiveness Concern**: Some people worry that probiotics might not be effective after an ileostomy since many probiotic bacteria are meant to colonize the large bowel, which is no longer present.

2. **Small-Intestine Strains**: On the other hand, some argue that certain strains, like Lactobacillus acidophilus, work primarily in the small intestine. Therefore, products containing these strains, such as Acidophilus or Acidophilus Bifidus, might still be beneficial for those with an ileostomy.

3. **Capsule Design and Timing**:
- Opt for capsules with a thin or fast-dissolving coating to ensure they release bacteria early enough in the small intestine.
- It's best to take probiotics with food, as stomach acid can destroy more bacteria if taken on an empty stomach.

4. **Clinically Used Product**: VSL#3 DS, a high-potency powder available by prescription, has been used for conditions like pouchitis and has been reported to be helpful. Over-the-counter versions, such as VSL#3 capsules and packets, can be found online and in some pharmacies.

5. **Dietary Sources**: Some individuals notice modest benefits from consuming yogurt and other fermented foods, though results can vary from person to person.

6. **Authoritative Resources**:
- For a comprehensive overview of probiotics, you can visit the Mayo Clinic's page on the topic.
- Greaterimmunity.com also provides general information on probiotics and prebiotics.

7. **Recommendation**: Since the effects of probiotics and prebiotics can differ from one person to another, it's advisable to consult a gastroenterologist. They can help determine which strains and doses might be most beneficial for someone with an ileostomy.
