Curcumin: A Review of Its Effects on Human Health

Narrative review summarizing human evidence that curcumin may aid oxidative and inflammatory conditions, metabolic syndrome, arthritis, anxiety, hyperlipidemia, and exercise-induced muscle soreness, while emphasizing poor native bioavailability and large boosts when co-formulated with piperine.

Scope

Narrative review (not a pooled MA) covering clinical and mechanistic themes for curcumin.

Outcome themes highlighted by authors

  • Potential roles in metabolic syndrome, OA pain, anxiety, lipids, and exercise-induced soreness.
  • Bioavailability: native curcumin poorly absorbed and rapidly cleared; piperine co-administration cited as increasing bioavailability up to ~2000% in referenced work.

Evidence hygiene

Treat mechanistic and small-trial claims as hypothesis-tier unless duplicated in dedicated meta-analyses (e.g. Doma et al. for EIMD biomarkers).

Publication

Hewlings SJ, Kalman DS. Nutrients. 2017 Oct 22;9(10):E1052. PMID 29065496.

Outcomes

  • Review frames curcumin as potentially helpful for exercise-induced inflammation/muscle soreness and multiple chronic conditions while stressing poor native bioavailability and formulation-dependent absorption.
  • Authors summarize piperine co-formulation as increasing curcumin bioavailability by up to ~2000% versus curcumin alone per cited literature in the review.
