01

What it is & primary uses

Plant compounds that reduce intestinal cholesterol absorption.

LDL-cholesterol reductionFood fortificationCardiovascular risk-factor management
02

Main benefits

  • Reliably lowers LDL cholesterol by a modest amount when consumed with meals.
  • It does not replace comprehensive cardiovascular risk management and can reduce carotenoid absorption.
03

Studied protocols

Research doses are grouped by outcome. They describe study designs—not a personal prescription.

LDL-cholesterol reduction

1.5–3 g/day plant sterols or stanols

High confidence
Study duration
Commonly 4–12 weeks; protocol and outcome vary
Interpretation
It does not replace comprehensive cardiovascular risk management and can reduce carotenoid absorption.
04Food sources & equivalents
Food sources & equivalents

Can food provide a studied amount?

Practical food match
Comparison target1.5–3 g/day plant sterols or stanols

Fortified spreads, yogurt drinks, nuts, seeds and vegetable oils can provide related dietary exposure, but food and extract milligrams are not automatically interchangeable.

Fortified spreads, yogurt drinks, nuts, seeds and vegetable oilsFood amount varies

Dietary exposure; verify composition before comparing with a studied supplement dose

How this was estimated
Dose Radar compares the declared active ingredient with official composition data or the studied standardized extract—not with marketing names.
Important limitation
Natural content, preparation, bioavailability and formulation vary. This comparison does not prove equal physiological effect.

Food equivalents compare ingredient mass using published composition values. They do not prove equal absorption, formulation, physiological effect, safety or personal need.

05How to take it for absorption & tolerance
Meal relationship

With food

Evidence-informed
With food; formulation and tolerance remain part of the comparison.

Food commonly improves gastrointestinal tolerance, although it can change absorption for some ingredients.

Practical approach
With meals, divided. Keep the formulation and daily total consistent with the evidence context shown above.
Watch for
Ezetimibe and lipid-lowering therapy require context

Meal guidance reflects human pharmacokinetic, clinical, official-label or evidence-review sources where available. A food pairing can change absorption or tolerability, but does not make a supplement necessary, effective or safe for every person.

06Supplement interaction check
Library interaction context156 ingredients · 0 mapped signals for this guide

An unlisted pair means no established pair-specific interaction was identified in this review—not proof that every dose, product or person is safe.

No pair-specific signal listedNo established interaction with another Dose Radar ingredient was identified in this review.

This is not proof that every dose, product or user context is safe. Medication and condition checks still apply.

07Research notes
Evidence verdict

Strong evidence for the stated context. It does not replace comprehensive cardiovascular risk management and can reduce carotenoid absorption.

The displayed amount comes from human research or an official evidence summary. It is not a personalized prescription, and formulation can change whether the comparison is valid.
