Understanding hs-CRP and Chronic Inflammation
By Charles Kamen, MD, board-certified neurologist
High-sensitivity C-reactive protein (hs-CRP) is a blood test that measures chronic, low-grade inflammation, and its cutoffs are simple: below 1.0 mg/L signals low cardiovascular risk, 1.0-3.0 mg/L average risk, and above 3.0 mg/L high risk. [1] This quiet "inflammaging" is a key driver of aging, heart disease, insulin resistance, and cognitive decline.
Dr. Charles Kamen, MD, a board-certified neurologist at LiveNow Longevity in Las Vegas, uses hs-CRP to guide anti-inflammatory care aimed at a longer healthspan and lower cardiovascular risk. Individual results vary.
What Is hs-CRP and What Does It Measure?
C-reactive protein is a protein your liver releases in response to systemic inflammation, and the high-sensitivity assay detects the low concentrations that flag chronic, silent inflammation rather than an acute infection. [1] That sensitivity is what lets hs-CRP capture inflammation you cannot feel.
Because it detects this background signal, hs-CRP has become a window into "inflammaging" — the slow, low-grade inflammation now recognized as a central mechanism of biological aging and a shared root of many age-related diseases.
How Do You Interpret hs-CRP Results?
hs-CRP results fall into three standard risk bands, and for longevity, lower is better. A single high reading can reflect a temporary infection or injury, so Dr. Kamen confirms elevated values with a repeat test and generally targets under 1.0 mg/L, where cardiovascular and metabolic risk is lowest:
- Low risk: below 1.0 mg/L
- Average risk: 1.0-3.0 mg/L
- High risk: above 3.0 mg/L
Why Does Chronic Inflammation Accelerate Aging?
Chronic low-grade inflammation damages tissues over decades and sits upstream of most age-related disease. [2] The inflammation hs-CRP measures, together with the oxidative stress that accompanies it, is linked to telomere shortening and cellular senescence — two hallmarks of biological aging. [4] Over time it contributes to:
- Cardiovascular disease: inflammatory processes damage the arterial lining (endothelium)
- Insulin resistance: inflammation interferes with insulin signaling and metabolic health
- Neurodegeneration: neuroinflammation contributes to cognitive decline
- Cancer development: chronic inflammation promotes cellular mutation
- Accelerated aging: inflammation drives biological age acceleration
hs-CRP, Cholesterol, and Heart Disease
Elevated hs-CRP is an independent risk factor for cardiovascular disease — it can flag heart risk even when cholesterol looks acceptable, which is why the two are best read together. In the landmark JUPITER trial, statin therapy reduced cardiovascular events in people with elevated hs-CRP. [3]
That is why Dr. Kamen pairs hs-CRP with a full lipid panel: lowering inflammation and optimizing cholesterol are complementary levers for protecting the heart and extending healthspan.
hs-CRP and Brain Health: A Neurologist's View
Chronic inflammation does not spare the brain: the inflammatory signals reflected in hs-CRP are tied to neuroinflammation, which contributes to cognitive decline as we age. As a board-certified neurologist, Dr. Kamen treats systemic inflammation as a brain-health issue, not only a cardiovascular or metabolic one.
This is also where sleep matters most. Inadequate sleep raises inflammatory markers, and restoring deep, consistent sleep is one of the most reliable ways to bring them back down — supporting a sharper mind, steadier energy, and better long-term brain health.
What Raises Your hs-CRP?
Many everyday exposures push hs-CRP upward, and most are modifiable. [2] Identifying which drivers apply to you is the first step Dr. Kamen takes before building a plan to lower them. Common contributors include:
- Chronic infections and autoimmune conditions
- Poor or insufficient sleep
- Smoking
- Obesity, especially excess visceral fat
- A sedentary lifestyle
- A processed diet high in refined carbohydrates
- Chronic psychological stress
How Do You Lower hs-CRP?
Chronic inflammation is highly modifiable, and hs-CRP can fall within weeks to months of consistent change. Dr. Kamen builds individualized, evidence-based protocols and typically re-tests after 8-12 weeks to confirm progress. Core strategies include:
- Omega-3 fatty acids (EPA/DHA) to reduce inflammatory mediators
- Vitamin D optimization to support immune regulation
- Glutathione IV therapy to bolster antioxidant defenses
- Sleep optimization, since inadequate sleep elevates inflammatory markers
- Resistance exercise to reduce systemic inflammation and build muscle
- Dietary changes that cut processed foods and refined carbohydrates
- Gut health support, because dysbiosis drives systemic inflammation
Key Takeaways
- hs-CRP risk bands: below 1.0 mg/L is low, 1.0-3.0 mg/L average, and above 3.0 mg/L high.
- hs-CRP measures chronic, low-grade "inflammaging" — a central driver of biological aging.
- Elevated hs-CRP is an independent cardiovascular risk factor; the JUPITER trial showed statin therapy reduced cardiovascular events in people with elevated hs-CRP.
- Common drivers include poor sleep, visceral fat, smoking, a sedentary lifestyle, a processed diet, and chronic stress.
- Omega-3s, vitamin D, sleep, resistance exercise, dietary change, gut health, and glutathione IV therapy all support lower inflammation.
- Dr. Kamen targets hs-CRP under 1.0 mg/L and typically reassesses after 8-12 weeks of a personalized protocol.
Common Questions
What is a healthy hs-CRP level?
For longevity, Dr. Kamen generally targets hs-CRP below 1.0 mg/L, which reflects low cardiovascular risk. Values between 1.0 and 3.0 mg/L indicate average risk and moderate inflammation worth addressing, while readings above 3.0 mg/L are high risk. A single elevated result is usually confirmed with a repeat test.
Is hs-CRP related to heart disease risk?
Yes. Elevated hs-CRP is an independent risk factor for cardiovascular disease and can flag heart risk even when cholesterol appears normal. In the JUPITER trial, statin therapy reduced cardiovascular events in people with elevated hs-CRP, which is why Dr. Kamen reads it alongside a full lipid panel.
Can chronic inflammation be lowered naturally?
Yes. Improving sleep, exercising regularly, supplementing omega-3s, optimizing vitamin D, and cutting processed foods all measurably reduce inflammatory markers. Supporting gut health helps too, since dysbiosis drives systemic inflammation. Dr. Kamen designs individualized protocols and confirms progress with repeat hs-CRP testing rather than relying on symptoms alone.
How quickly can hs-CRP levels change?
hs-CRP can shift relatively quickly — often within weeks to a few months of consistent lifestyle change or targeted treatment. Dr. Kamen typically reassesses after 8-12 weeks of a protocol to measure the effect. Acute illness or injury can also temporarily raise it, so timing of the test matters.
Does glutathione IV therapy really reduce inflammation?
Glutathione is a master antioxidant that helps neutralize the oxidative stress feeding chronic inflammation. IV therapy delivers it directly, supporting the body's antioxidant defenses. Many patients see improvement in inflammatory markers when it is combined with sleep, exercise, and dietary changes as part of a broader protocol. Individual results vary.
Does chronic inflammation affect the brain?
Yes. The same inflammatory signals hs-CRP measures are linked to neuroinflammation, which contributes to cognitive decline over time. As a neurologist, Dr. Kamen treats elevated inflammation as a brain-health concern and prioritizes sleep, which lowers inflammatory markers and supports sharper thinking, steadier energy, and long-term cognitive resilience.
Managing chronic inflammation is central to longevity medicine, and hs-CRP is one of the clearest, most actionable markers to track. Schedule a consultation with Dr. Kamen to assess your inflammatory biomarkers and build a personalized plan to lower them.
