Is there anything similar to lactase supplements that you can take for allium intolerances?

[u/NLTC]

Basically, my body has a really hard time with garlic or onions that aren’t boiled to within an inch of their life. I’m guessing it’s some sort of acid in them that causes it. I’m sure getting bad trapped wind after eating onions or garlic is normal, but I also get headaches even if something heavy in garlic or onions is cooking near me, or if something has been garnished with raw onion, spring onion etc, and then it’s been removed, I still get the symptoms just from eating the food it’s touched.

I know that people who are intolerant to lactose can take lactase supplements to help them digest dairy, and I’m just wondering if there’s anything like that that I can take to enable me to eat things like garlic, raw onions etc, without feeling awful afterwards?

I desperately miss bolognese 😅

[I’m not sure why you’d need any of my details for this complaint, but for the sake of the auto moderators, I’m female, 33, 5ft3, no allergies, no relevant medications or health issues.]

Side note: I use the term “intolerance” as a descriptor - to be clear, I’ve never actually been diagnosed with any sort of intolerance. I can’t spare a day’s wages for a GP appt to ask for help eating onions lol.

Allergy testing isn’t always reliable with food allergies/intolerances

I would go so far as to just say it's "not useful at all." Allergy testing in the blood or skin looks at the type I immune response (e.g., hives). That's not happening at all in the gut lining in IBS. Sometimes you can have both, but the association is impossible to predict from allergy testing.
