The main Flax&Kale location on Carrer dels Tallers has a clearly marked gluten-free menu and knowledgeable staff, but does not guarantee against cross-contamination and has no dedicated kitchen or fryer at this site; staff have directed celiac diners to the Passage location for safer preparation. The Passage location, now permanently closed, was reported by multiple community reviewers as a fully dedicated gluten-free kitchen with a dedicated fryer.

Multiple community reviewers note the venue is 'good for dairy-free', and plant-based cheese alternatives such as cashew mascarpone are used, though no dedicated dairy-free protocol or marked menu for dairy is documented in sources.

A small number of community reviewers note the venue is 'good for egg-free,' which is consistent with its largely plant-based menu. No formal egg-free menu marking or dedicated protocol is evidenced.

One reviewer who follows a low-FODMAP diet for IBS reported that the kitchen could not accommodate requests to remove high-FODMAP ingredients such as shiitake and spring onion. The salad arrived with a garlic vinaigrette. That reviewer stated they would not return for FODMAP needs.
