Follow-up from Monday: why does the omega-6:3 ratio actually matter day to day?
Systemic inflammation isn't the swollen ankle or the red, hot joint you can see and feel β that's acute inflammation, and it's your body working correctly. What we're talking about is different: a low-grade, background inflammatory state running at a cellular level, all the time, that you can't feel directly but that often shows up as:
β’ Morning stiffness that takes longer than it should to ease off
β’ An energy crash by mid-afternoon, whatever you did the night before
β’ Joint aches that move around, or don't line up with any specific injury
β’ Training recovery that takes days instead of hours
β’ Skin that flares for no obvious reason
β’ Feeling a bit foggier, a bit less sharp, than you used to.
None of these on their own means something's wrong. But together, they're often the everyday signature of a baseline inflammatory state β and the single most measurable driver of that baseline is your omega-6:3 ratio.
It matters beyond how you feel day to day, too. Elevated ratios are linked to increased cardiovascular risk (the AA:EPA ratio is now recognised as a heart disease risk marker in its own right), to metabolic dysfunction like insulin resistance, and to immune dysregulation relevant to conditions like eczema, psoriasis and IBD.
None of this is a diagnosis β it's a modifiable biological environment, and that's exactly why it's worth measuring rather than guessing.
Here's the catch: taking "a fish oil" isn't the same as fixing it. Most over-the-counter omega-3 is in a poorly absorbed form, oxidises quickly once opened, and without knowing your starting number you're guessing whether it's doing anything at all. If you are taking an omega 3 supplement, wouldn't you want the hard proof it is working (or to do something about it if it isn't)
That's the whole idea behind test, don't guess. Tomorrow β my own numbers.
