This topic is about someone with an ileostomy who is trying to figure out what some unfamiliar substances are in their ostomy pouch. They noticed a jelly-like piece and a white powder, and they are curious if these are related to their supplements and if they are absorbing them properly. Here are some helpful insights and advice:

1. The jelly-like piece might be an undigested fish-oil soft-gel. These can sometimes swell and look like jelly if they don't dissolve completely.

2. The white powder is likely undissolved magnesium from a capsule. It's common for people with ileostomies to pass powdered or partially intact medications.

3. Time-release or enteric-coated capsules often come out whole, so it's best to avoid these after an ileostomy.

4. Chewing or crushing magnesium tablets can help with absorption, and the taste is usually tolerable.

5. Switching to liquid forms of supplements, like magnesium and fish oil, can improve absorption since liquids are generally absorbed better by people with ileostomies.

6. If you're concerned about the appearance of your output, you might consider using opaque pouches or those with a viewing window for occasional checks.

7. It's a good idea to talk to a pharmacist or doctor about non-gelatin, immediate-release, or liquid alternatives for any medication that seems to be undigested.

These tips can help ensure that you're getting the most out of your supplements and medications.
