Can I lower hs-CRP with supplements instead of drugs?

Supplements can lower hs-CRP modestly. The evidence-graded options are: omega-3 fatty acids at 2–4 grams per day EPA plus DHA, reducing hs-CRP by approximately 0.3–0.7 mg/L; high-dose curcumin (500–2000 mg/day of standardized extract), producing approximately 0.5–1 mg/L reduction in multiple small RCTs; and magnesium supplementation in deficient men, with modest but consistent anti-inflammatory effects. These are real effects.

The clinical context matters: a man with hs-CRP of 4.5 mg/L who adds omega-3s may reach 3.9–4.2 mg/L. He is still in the high-risk category. The supplement approach as a primary strategy for meaningfully elevated hs-CRP is not clinically sufficient in the same way that statin therapy, visceral fat reduction, or treating sleep apnea is clinically sufficient. Supplements are useful adjuncts within a strategy that addresses primary drivers. They are not a substitute for identifying and treating the source of the inflammation.

Cardiologist's calibrated position, Early (3) for curcumin, Promising (2) for high-dose omega-3s. Neither replaces the primary intervention hierarchy.

What to do: Use omega-3 supplementation as an adjunct, not a primary strategy. Target 2–3 grams of combined EPA plus DHA from fish oil or algal oil. Address visceral fat, sleep, and dental health first.
