For one thing, do your research on Bile Salts, or Ox Bile, Bile Acids to support having No Gallbladder. I have mine but I read so many stories from those who had their's removed and live in a lot of pain and misery in spite of No Gallbladder. The G.B. we are born with is there for a reason. https://wellnessrepair.com/what-you-must-do-if-your-gallbladder-has-been-removed/ I take Ox Bile to keep things in good working condition with my G.B. Of course, key is to keep G.B. healthy primarily thru nutrition.
My daughter had hers removed a few years ago in her early twenties. She can tell if she eats too many fried foods, but it's more of an intense indigestion, not an unbearable pain. She even thoroughly enjoys her beer intake. She doesn't take anything extra for it, but she is still under 30. Age may make a difference. When your younger, you bounce back faster.
I am sure there's a purpose for each of our body parts. My gallbladder was removed about ten years ago. There was too much information in that link for me to process but I haven't had any troubles that I have attributed to the absence of a gallbladder. Of the few mentioned there that I have experienced, it has been only recently, a decade after my gallbladder was removed, so I don't know if I could attribute it to that.
I guess there might be a bit of logic with the supplement but here’s the rub. The liver makes about a cup of bile whilst we are at rest and the gallbladder is only a storage unit for the substance. Without the storage unit, the liver still produces bile which is the problem a few people have because there are times when the discomfort comes from having too Much bile in the intestinal tract. Normally, over a small period of time, the liver will adapt to the situation and smaller amounts will be produced and at different periods of time. Now, since bile is only used for one major purpose which is to break down ingested fats, all the majority of people have to do is to watch one’s diet. Perchance someone doesn’t wish to take the diet seriously, then the extract might be the way to go but the research is so up in the air about it that it’s hard to ascertain exactly what good it does. Like many other extracts and supplements, some people swear by them and others say it does nothing special so I guess it’s up to the individual how they wish to spend their money. To be sure though, with my limited resources, if I have to be like my dad and leave the complex fats alone, that’s what I will do first. If I had any trouble after that, I think I’d see a good physician and do a heckova lot more independent research.
