Strong for LDL lowering health 6 linked sources Content audit 2026-05-16

Headline Finding

Dose-response meta-analysis of 124 studies found consistent LDL lowering across roughly 0.6-3.3 g/day intakes.

Dose Context

Common evidence-based intakes are about 1.5-3 g/day with meals, usually from fortified foods or specific capsule/tablet formats.

Important Caveat

They have not replaced outcome-proven therapies. They can lower carotenoid levels slightly, so diet quality still matters.

How To Read This Rating

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
