Help me find something for my mom please!

My mom has gout flare ups for no reason. she is so thin, eats as well as she possibly can/low inflammation foods, but still the flare ups she has you would think she is eating the worst foods.

I need to know what are some good supplements out there that can support her in addition to her diet. I’ve been reading about CoQ10( needs alpha lipoic acid to be better absorbed), quercetin (but it seems more so for allergy sufferers and shouldn’t be taken long term/daily?). Is there anything else out there? Any one has gout and high uric acid and has a recommendation for a daily supplement? Thank you!!
