This topic is about finding a replacement for a specific type of ostomy powder called karaya powder. The person asking for advice has been using a bottle of this powder for four years, and now that it's almost empty, they are looking for alternatives since their usual supplier no longer lists the exact product they used.

Here are some helpful suggestions:

1. Karaya powder is made from karaya gum and is not tied to a specific brand. Any product labeled as "karaya powder" will work just as well.

2. Although the original supplier, Edgepark, no longer lists the exact item, they still offer karaya powder from other manufacturers. You can log in to their website, search for "karaya," and find alternative products to order.

3. If you can't find what you need at Edgepark, consider checking online retailers like Amazon, which also carry karaya powder.
