Chronic inflammation — the silent driver of ageing

Read time: ~4 minutes

Inflammation has a reputation problem. Most people think of it as something visible — a swollen ankle, a red cut healing over. That kind of inflammation is healthy. It's your immune system doing exactly what it should.

The type of inflammation that drives ageing is different. It's quiet, persistent, and often completely invisible — and researchers now consider it one of the central mechanisms behind why we age the way we do.

Two kinds of inflammation

Acute inflammation is the body's emergency response. When you injure tissue or encounter a pathogen, immune cells flood the area, neutralise the threat, and then stand down. The whole process is designed to resolve — once the threat is gone, so is the inflammation.

Chronic low-grade inflammation is something else entirely. It's a state in which inflammatory signalling never fully switches off — not because of an ongoing threat, but because the regulatory systems that normally resolve inflammation have become dysregulated. There's no injury to heal, no infection to clear, but the immune system remains in a state of low-level activation.

This persistent background inflammation — now widely referred to in research as inflammaging — is one of the most consistently replicated findings in gerontology. Study after study shows that older adults with elevated inflammatory markers have worse health outcomes: faster cognitive decline, higher cardiovascular risk, reduced muscle mass, and shorter healthspan.

A landmark 2018 paper in Nature Medicine by Francesca Giunta and colleagues brought the concept mainstream, but the underlying research had been building for decades. Elevated CRP (C-reactive protein), IL-6, and TNF-α are now used as biomarkers not just of disease, but of biological ageing rate.

What drives chronic inflammation?

Several factors contribute to the chronic inflammatory burden that accumulates over a lifetime:

1. Adipose tissue — particularly visceral fat (the fat around organs) — acts as an active endocrine organ, secreting pro-inflammatory cytokines including IL-6 and TNF-α. More visceral fat means more inflammatory signalling, essentially continuously.
2. The gut microbiome — a compromised gut lining allows bacterial fragments (lipopolysaccharides) to enter systemic circulation, triggering an ongoing immune response. Dysbiosis — an imbalance in gut bacteria — is closely associated with elevated inflammatory markers.
3. Cellular senescence — as cells age and accumulate damage, some enter a state called senescence: they stop dividing but don't die. Senescent cells secrete a cocktail of inflammatory signals (the senescence-associated secretory phenotype, or SASP), actively promoting inflammation in surrounding tissue.
4. Oxidative stress — an excess of reactive oxygen species relative to the body's antioxidant capacity directly triggers inflammatory signalling pathways, particularly NF-κB.
5. Sleep deprivation — even short-term insufficient sleep raises CRP and IL-6 in studies. Chronic poor sleep is one of the most reliable ways to elevate inflammatory markers.
6. Processed diet and blood sugar dysregulation — refined carbohydrates, industrial seed oils, and ultra-processed foods are consistently associated with elevated inflammatory markers in epidemiological and intervention studies.
7. Psychological stress — the stress response involves cortisol, which in the short term is actually anti-inflammatory. Chronic stress, however, leads to glucocorticoid resistance — the body stops responding to cortisol's anti-inflammatory signals, allowing inflammatory cascades to persist.

How inflammation damages the body over time

Chronic inflammation doesn't cause a single disease — it creates the biological conditions in which many diseases become more likely. The mechanisms are multiple:

• Cardiovascular disease — inflammation damages the endothelium (the lining of blood vessels), contributing to the formation of atherosclerotic plaques. Elevated CRP is one of the strongest independent predictors of cardiovascular events.
• Neurodegeneration — neuroinflammation (inflammation within the brain and nervous system) is implicated in Alzheimer's disease, Parkinson's, and cognitive decline more broadly. Chronically elevated IL-6 and TNF-α are associated with reduced BDNF — the protein critical to neuroplasticity and memory.
• Metabolic dysfunction — inflammatory signalling interferes with insulin receptor function, contributing to insulin resistance and metabolic decline.
• Muscle loss (sarcopenia) — chronic inflammation promotes muscle protein breakdown and inhibits the anabolic signalling needed for muscle maintenance. Loss of muscle mass with age is partly an inflammatory phenomenon.
• Cellular ageing — NF-κB activation (the master switch of inflammatory gene expression) directly accelerates telomere shortening and epigenetic ageing. Inflammation and biological age are bidirectionally linked.

What reduces chronic inflammation?

The strongest evidence points to a cluster of lifestyle and nutritional interventions:

• Diet — Mediterranean-style eating patterns consistently reduce inflammatory markers. Omega-3 fatty acids, polyphenols, and fibre are particularly well-supported.
• Exercise — regular moderate exercise has a powerful anti-inflammatory effect, partly through IL-6 released from contracting muscle (which, in this context, triggers an anti-inflammatory cascade rather than a pro-inflammatory one).
• Sleep — prioritising 7–9 hours of quality sleep is one of the most consistently effective interventions for lowering inflammatory biomarkers.
• Stress management — practices that reduce chronic psychological stress reduce glucocorticoid resistance and lower inflammatory signalling over time.
• Targeted nutrition — specific compounds have well-characterised anti-inflammatory mechanisms, particularly curcumin, PEA (palmitoylethanolamide), and astaxanthin.

How AEVUM's Daily Vitals Longevity Complex addresses chronic inflammation

Inflammation balance is the first of AEVUM's five biological systems — and for good reason. Chronic inflammation degrades every other system. Address it meaningfully, and you create better conditions for cellular resilience, metabolic health, energy production, and nervous system regulation.

1. HydroCurc® (curcumin, 500mg) modulates NF-κB — the master regulator of inflammatory gene expression — and inhibits COX-2 and LOX enzymes, suppressing production of TNF-α, IL-1β, and IL-6. A 2019 meta-analysis of 15 RCTs found consistent reductions in CRP, IL-6, and TNF-α with bioavailable curcumin. The HydroCurc® form uses LipiSperse® technology to achieve 3× greater bioavailability than standard curcumin — which matters, because most of the evidence for curcumin is attached to bioavailable forms.
2. Levagen+® (PEA, 375mg) works at a more localised, cellular level — activating PPAR-α to regulate inflammatory gene expression and modulating mast cell and glial cell activity. A 2022 clinical study found significant reductions in pro-inflammatory cytokines IL-1β and IL-2 with Levagen+® supplementation. PEA also supports the endocannabinoid system — which itself plays a regulatory role in inflammatory response and declines with age.
3. Astaxanthin (5mg), alpha lipoic acid (100mg), vitamin C, and zinc contribute through the antioxidant network — reducing the oxidative stress that is both a driver and a consequence of chronic inflammation, and helping break the self-reinforcing cycle.
4. Resveratrol (100mg) activates the SIRT1 pathway, which regulates inflammatory gene expression alongside DNA repair and metabolic function. A 2021 systematic review across 11 trials found significant reductions in CRP, IL-6, and TNF-α with resveratrol supplementation.

Together, these ingredients address inflammation not as a single target but as a system — which is how inflammation itself operates.
