The 3am jingle of the collar. The raw patch behind the ear. Allergy season is loud in your house. Here is the calm, honest version of what fish oil can and can’t do about it.

It is support, not treatment: it works over weeks by shifting what the skin has to work with, not by silencing a symptom overnight.
