CRP
C-reactive protein
A protein the liver makes when inflammatory signals rise. The high-sensitivity version (hs-CRP) is the most common way to gauge low-grade, body-wide inflammation.
Body science
Inflammation isn't the enemy. The kind that never switches off is.
Acute inflammation is how your body defends and rebuilds — a fire that flares and then goes out. The trouble starts when that fire smolders quietly for years. Here's what's actually happening, and what the research does and doesn't say.

What it is
First, what inflammation actually is.
Inflammation has a bad reputation it doesn't fully deserve. At its core it's just your immune system doing its job — the coordinated response that rushes blood, fluid, and immune cells to a spot that's been injured or invaded. The redness around a cut, the swelling of a sprained ankle, the heat of a healing wound: that's inflammation working exactly as designed.
The useful distinction isn't 'inflammation good' or 'inflammation bad.' It's acute versus chronic. Acute inflammation is fast, local, and self-limiting — it shows up, does its work, and resolves. Chronic, low-grade inflammation is the opposite: a faint, body-wide signal that never fully shuts off, often without any obvious symptom at all.
That second kind is what researchers have spent the last two decades trying to understand, because a persistent low hum of inflammation behaves very differently from a clean flare-and-resolve. The biology is the same machinery — it's the duration that changes everything.
“Acute inflammation is a fire that goes out. Chronic inflammation is one nobody ever put out.”
How the alarm works
The inflammatory cascade, step by step.
Inflammation isn't one event — it's a relay. A trigger sets off a chain of molecular signals that ends in the familiar redness, heat, and swelling. Here's the sequence, simplified.

Trigger
An injury, irritant, or pathogen damages tissue and releases distress signals.
What you can see
The four classic signs of acute inflammation.
Physicians have described the same four signs for nearly two thousand years. They're the visible surface of the cascade — what happens at the tissue when blood flow and immune activity ramp up. Tap each to see what's going on underneath.
Redness · Rubor
Blood vessels widen to bring more blood to the site, which flushes the area red.

Local vs. everywhere
Acute is somewhere. Chronic is everywhere.
The two kinds of inflammation don't just differ in how long they last — they differ in where they happen. Acute inflammation concentrates at one spot you can usually point to. Chronic, low-grade inflammation is diffuse: a faint signal spread across the whole body. Toggle between them.
A sprained ankle, a cut, an infection — the response is intense but focused on one place, and it fades as you heal.
Two very different fires
Acute resolves. Chronic lingers.
Plot inflammation over time and the two patterns look nothing alike. Acute inflammation spikes hard and then returns all the way to a healthy baseline. Chronic inflammation settles into a low plateau and just… stays there.
Acute inflammation
Spikes to fight a threat, then resolves back to baseline. This is the system working.
Chronic low-grade
A low-grade signal that never switches off — the kind linked to long-term wear.
Illustrative, not to scale. The point isn't the exact numbers — it's the shape: one curve comes home, the other doesn't.
Measuring the smoke
How inflammation gets measured.
Because chronic inflammation often has no symptoms, clinicians look for molecular fingerprints in the blood. These are the markers you'll see most often discussed in the research.
IL-6
Interleukin-6
A cytokine — a messenger molecule — that helps kick off the response and, in turn, drives the liver to produce more CRP.
TNF-α
Tumor necrosis factor alpha
One of the central pro-inflammatory signals released early in the cascade to recruit and activate immune cells.
ESR
Erythrocyte sedimentation rate
An older, indirect test — how quickly red blood cells settle — that rises non-specifically when inflammation is present.
What the research shows
The honest state of the evidence.
Here's what's well-established about inflammation, and where the science is still being mapped. Every claim links to its source.
Settled
Acute inflammation is essential
There's no debate here: the acute inflammatory response is a normal, necessary part of how the body defends against threats and repairs damage. Without it, healing doesn't happen. The goal is never to eliminate inflammation — it's to support a healthy, well-resolved response.
The mechanism
NF-κB is a master switch
The NF-κB pathway is one of the best-characterized control points of the inflammatory response — the molecular switch that turns inflammatory genes on. It's a heavily studied target precisely because it sits so early in the cascade.
Why it matters
Chronic, low-grade inflammation is hard to see
A growing body of work describes a persistent, low-level inflammation that often produces no symptoms yet shows up in blood markers. Because it's quiet, it tends to be detected through testing rather than how you feel — which is part of why it gets so much research attention.
What may help
Diet, lifestyle, and certain nutrients are studied
Sleep, movement, and dietary patterns are consistently linked to inflammatory markers, and specific nutrients — omega-3s, polyphenols like curcumin — are studied for their role in supporting a healthy inflammatory response. The direction is encouraging; effect sizes vary and depend on the person.
Our approachExplore our supplements
Going deeperWhere Manna fits — and where it doesn't.
We build supplements that are formulated to support a healthy inflammatory response, using ingredients with real research behind them and delivery systems that actually get those ingredients into your bloodstream. That's the lane we're good at.
What we won't do is pretend a supplement treats inflammation or any condition tied to it — it doesn't, and anyone claiming otherwise is selling you something. If you're concerned about chronic inflammation, that's a conversation for your clinician, ideally with real bloodwork in hand. Our job is to make the nutrition side trustworthy.
Curcumin & Curcuminoids
Curcumin is the most-studied nutrient in the inflammation conversation — and the textbook case of a compound that needs better delivery to do anything at all. Here's the science.
