Why the study?

Astaxanthin shows positive effects in reducing metabolic syndrome risk, but findings from individual studies remain inconclusive.

Does astaxanthin improve lipid and blood pressure profiles in adults at risk of metabolic syndrome?

Population

321 adults with risk factors of MetS across 7 studies

Comparison

Astaxanthin supplementation vs comparator

Design

Systematic review and meta-analysis of randomized controlled trials

Authors

Overview

May modestly lower SBP, TC, and LDL-C in at-risk adults; leaves open definitive role pending larger RCTs.

Structured PICO

Does astaxanthin improve lipid and blood pressure profiles in adults at risk of metabolic syndrome?

P
Population
321 adults with risk factors of metabolic syndrome (pooled from 7 randomized controlled trials)
I
Intervention
Astaxanthin
O
Outcome
Total cholesterol, systolic blood pressure, and low-density lipoprotein cholesterolsurrogate

Astaxanthin supplementation may significantly reduce LDL cholesterol in adults at risk for metabolic syndrome, though its effects on total cholesterol and blood pressure appear marginal.
