How to Lower CRP and Chronic Inflammation: 8 Evidence-Based Methods

Learn what can lower hsCRP, which lifestyle changes have the best evidence, when to repeat the test, and when an elevated result needs medical follow-up.

An elevated high-sensitivity C-reactive protein (hsCRP) result is a signal, not a diagnosis and not a number to suppress at any cost. The useful question is what is driving the inflammation. A recent infection, excess body fat, smoking, poor sleep, a chronic inflammatory condition, and other factors can all contribute.

The American Heart Association describes hsCRP as one part of a cardiovascular-risk assessment. It is most useful when interpreted alongside blood pressure, cholesterol, blood glucose, body weight, smoking history, family history, and other risk factors. If two measurements are elevated, a clinician may look for other sources of inflammation and discuss the next steps [1].

This guide separates three things that are often blurred together:

• how to make sure the result reflects your usual state
• lifestyle changes that may lower hsCRP and improve health more broadly
• situations where treating the underlying cause matters more than another lifestyle hack

First, understand what CRP measures

C-reactive protein (CRP) is an acute-phase protein made by the liver in response to inflammatory signals. Standard CRP and hsCRP measure the same protein. The difference is that the high-sensitivity assay measures lower concentrations more precisely.

• Standard CRP is commonly used when clinicians are evaluating substantial inflammation from infection, injury, or an inflammatory disease.
• hsCRP can help refine cardiovascular-risk assessment when the result is interpreted in the right clinical context.

See CRP vs hsCRP for a focused comparison of the two tests.

Higher hsCRP is associated with higher cardiovascular risk, but CRP itself should not be treated as the sole cause of that risk. It is a marker of an inflammatory pathway. Whether a particular result should change treatment depends on the rest of the person’s risk profile [1,2].

Before trying to lower hsCRP

Do not build a plan around a result taken during a cold, injury, dental infection, inflammatory flare, or other acute event. Hard exercise shortly before a blood draw can also temporarily affect inflammatory markers.

If a result is unexpectedly high:

1. Consider whether you were fully well when the sample was taken.
2. Review the result and your symptoms with a clinician, especially when the elevation is marked or persistent.
3. Repeat the test at a clinically appropriate time if your clinician recommends it. The goal is to establish whether the elevation persists, not to average away a meaningful abnormality.

Historical cardiovascular-risk categories have described results below 1 mg/L as lower risk, 1 to 3 mg/L as intermediate risk, and above 3 mg/L as higher risk. These categories are context, not treatment targets. Your own lab report and overall cardiovascular-risk assessment should guide the interpretation.

8 evidence-based methods

1. Use a Mediterranean-style eating pattern

The evidence is stronger for an overall dietary pattern than for any single “anti-inflammatory” food. A Mediterranean-style pattern emphasizes:

• vegetables, fruit, beans, lentils, nuts, and whole grains
• olive oil as a main added fat
• fish and other minimally processed protein sources
• fewer refined carbohydrates, processed meats, and highly processed foods

A 2025 meta-analysis of 33 randomized trials found that Mediterranean-diet interventions reduced hsCRP on average, although results varied between studies [3]. In a PREDIMED substudy of older adults at high cardiovascular risk, the Mediterranean-diet group assigned extra-virgin olive oil had a modest reduction in CRP compared with the low-fat control group after three months [4]. Those findings support the pattern, but they do not justify promising that everyone will see the same percentage change.

There is no good reason to eliminate all seed oils solely to lower hsCRP. Focus on the overall quality of the diet and replace foods high in saturated fat or refined carbohydrate with unsaturated fats and minimally processed foods where practical.

2. Reduce excess body fat if it is relevant to you

Adipose tissue, particularly visceral fat around the abdominal organs, contributes to inflammatory signaling. A systematic review of weight-loss interventions found that CRP generally fell as weight was lost, with larger absolute changes among people who started with higher CRP [5].

The right approach is one you can sustain. It may combine a modest calorie deficit, adequate protein, resistance training, aerobic activity, sleep support, and clinical treatment when appropriate. A single waist cutoff or protein dose is not suitable for every person, so this guide does not prescribe one.

Weight loss is not the answer for everyone. If your weight is already appropriate or weight loss would be unsafe, investigate other causes rather than forcing the scale down.

3. Exercise consistently

Regular exercise can reduce hsCRP, especially when it also improves fitness or reduces body fat. A meta-analysis of 83 controlled trials found a small average reduction in CRP, with larger changes in studies where body mass index or body fat also fell [6]. That means exercise is worthwhile even though the size of the hsCRP response varies.

A practical target for most adults is the US physical-activity recommendation: at least 150 minutes of moderate aerobic activity each week, plus muscle-strengthening activity on two or more days. Build up gradually if you are currently inactive or have a medical condition. One hard workout is not a shortcut, and strenuous exercise near the blood draw can make a follow-up result harder to interpret.

4. Protect sufficient, regular sleep

Sleep and inflammation are connected, but the evidence does not support a precise promise such as “fix sleep and hsCRP will fall 20%.” An updated meta-analysis of experimental sleep-deprivation studies found that CRP rose after several consecutive nights of partial sleep restriction, while a single night did not show the same association [7].

Aim for a regular schedule and enough sleep to function well. The American Academy of Sleep Medicine and Sleep Research Society recommend at least seven hours a night for healthy adults, while individual needs vary. Address obstacles such as late caffeine, alcohol near bedtime, or an inconsistent schedule. These steps have benefits beyond hsCRP even when the lab value does not move substantially.

5. Check for sleep apnea when the symptoms fit

Obstructive sleep apnea causes repeated drops in oxygen and fragmented sleep. Consider medical evaluation if you snore loudly, have witnessed pauses in breathing, wake with headaches, or remain sleepy despite enough time in bed.

A 2025 meta-analysis of randomized trials found that continuous positive airway pressure treatment lowered CRP on average, but the authors also called for more trials [8]. Treating sleep apnea is important for its broader health consequences, not merely to improve one biomarker.

6. Do not smoke

Smoking exposes blood vessels and the lungs to inflammatory and oxidative stress. Not smoking is one of the lifestyle measures the American Heart Association recommends when reducing overall heart risk in the setting of an elevated hsCRP [1].

If you smoke, use a proven cessation plan rather than relying on willpower alone. A clinician can help with counseling, nicotine replacement, or prescription treatment. The cardiovascular benefit is the reason to stop, even if hsCRP does not immediately normalize.

7. Find and treat the underlying condition

Persistent inflammation can reflect an autoimmune condition, chronic infection, metabolic disease, or another medical issue. hsCRP cannot tell these causes apart [13].

Seek medical review rather than self-treating when an elevation persists, is marked, or comes with symptoms such as fever, unexplained weight loss, chest pain, shortness of breath, severe fatigue, joint swelling, or persistent gastrointestinal symptoms. Treatment should target the diagnosis. Do not stop prescribed or over-the-counter medicines, including NSAIDs, simply to change a CRP result.

8. Treat supplements as optional and condition-specific

Food-first advice is simpler than a universal supplement protocol because supplement effects vary by population, formulation, and dose.

For omega-3 supplements, a 2025 dose-response meta-analysis found reductions in CRP in some groups with cardiometabolic conditions, but no significant reduction in participants with overweight or obesity as a group [9]. Another meta-analysis found no clear evidence that EPA is more anti-inflammatory than DHA [10]. This does not support the common claim that everyone needs 2 to 4 grams daily or that lower doses are ineffective. High-dose omega-3 supplements can also interact with medicines, and large trials have reported a small increase in atrial fibrillation risk with 4 grams daily in people with or at high cardiovascular risk [11].

Curcumin evidence is also mixed. A systematic review of randomized trials found no significant overall effect on CRP or hsCRP [12]. Later reviews have reported benefits in selected populations, but variation in formulations and study quality makes a universal dose inappropriate.

Discuss supplements with a clinician or pharmacist if you take medication, are pregnant, have a bleeding disorder, or are considering a high dose. Supplements should not delay evaluation of a persistent elevation.

What to measure and when to retest

For most people, the next useful measurement is another hsCRP result obtained when well, not a large self-ordered “inflammation panel.” ESR, ferritin, blood counts, glucose markers, or other tests may be appropriate when a clinician is investigating a particular cause, but they are not a universal companion panel.

There is also no universal retesting schedule. The timing depends on why the test was ordered, how high it was, whether you were ill, and whether the result could change a clinical decision. When tracking a lifestyle change, use similar testing conditions and allow enough time for the change to become established. Ask the clinician interpreting the result whether weeks or months is the right interval in your situation.

Choose an hs-CRP testing option

You can order the individual hs-CRP test or compare it with broader panels. See the dated hs-CRP test cost comparison for advertised prices and fee differences across providers.

The bottom line

The goal is not to chase the lowest possible hsCRP. First confirm that the result is persistent and interpretable. Then work on the drivers that matter for your health: diet quality, excess body fat when relevant, regular exercise, sufficient sleep, smoking, and any underlying condition.

Lifestyle changes can lower hsCRP on average, but no responsible guide can predict a personal percentage reduction or timeline. The more important outcome is lower overall cardiovascular and metabolic risk.
