What it is & primary uses
Macular carotenoids used in the AREDS2 eye-health formulation and obtained from colorful foods.
Main benefits
- The AREDS2 combination is evidence-based for selected people with intermediate or advanced age-related macular degeneration.
- It is not proven to prevent AMD in everyone or replace eye care; the clinical context matters.
Studied protocols
Research doses are grouped by outcome. They describe study designs—not a personal prescription.
10 mg lutein + 2 mg zeaxanthin/day in AREDS2
- Study duration
- Commonly 4–12 weeks; protocol and outcome vary
- Interpretation
- It is not proven to prevent AMD in everyone or replace eye care; the clinical context matters.
Clinical or experimental context—professional guidance is especially appropriate.
04Food sources & equivalents＋
Can food provide a studied amount?
Kale, spinach, corn, egg yolk and orange peppers can provide related dietary exposure, but food and extract milligrams are not automatically interchangeable.
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.

With dietary fat
Fat and formulation can materially change exposure; a meal does not turn an unsupported claim into an effective one.
- Practical approach
- With a meal containing fat. Keep the formulation and daily total consistent with the evidence context shown above.
- Watch for
- No major common interaction established
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.

An unlisted pair means no established pair-specific interaction was identified in this review—not proof that every dose, product or person is safe.
This is not proof that every dose, product or user context is safe. Medication and condition checks still apply.
07Research notes＋
Strong evidence for the stated context. It is not proven to prevent AMD in everyone or replace eye care; the clinical context matters.
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.
