What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This softgel contains 2 active ingredients: LuteinRich Lutein and zeaxanthin. Both are carotenoids — plant pigments your eyes naturally contain.

Lutein and zeaxanthin accumulate in the macula (the part of your retina responsible for sharp, detailed vision) and may help protect against age-related damage. The softgel is filled with safflower oil and organic flaxseed oil to help your body absorb these fat-soluble compounds, plus beeswax and sunflower lecithin as inactive ingredients.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: eye and macular health support.
  • We looked for evidence on: Age-related macular degeneration (AMD), Asthenopia (eye strain), Cataracts, Central serous retinopathy, Choroideremia, Diabetic retinopathy — and 4 related terms.
  • The strongest evidence on file: Lutein is rated "Possibly Effective" for Age-related macular degeneration (AMD) (Natural Medicines).
  • Also on file: Lutein is rated "Possibly Effective" for Cataracts.
  • Also on file: Zeaxanthin is rated "Possibly Effective" for Age-related macular degeneration (AMD).

Lutein is possibly effective for age-related macular degeneration (AMD) and cataracts, though the evidence isn't conclusive. Zeaxanthin is also possibly effective for AMD.

Neither ingredient has reliable evidence for other conditions listed here — retinitis pigmentosa, retinopathy of prematurity, bronchopulmonary dysplasia, and zeaxanthin for cognitive decline and Alzheimer disease all lack sufficient research to rate them.

The evidence, ingredient by ingredient Lutein Zeaxanthin

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Lutein from food and typical supplement doses is generally well tolerated; doses up to 20 mg daily have not caused adverse effects in trials. Both lutein and zeaxanthin are rated Likely Safe in pregnancy and lactation, though safety data on concentrated supplement doses — especially while breastfeeding — is limited.

If you're pregnant or nursing, talk with your doctor or pharmacist about whether this 40 mg dose is right for you, since most safety studies focus on lower amounts or food sources.

Antidiabetes Drugs

Theoretically, taking zeaxanthin with antidiabetes drugs might increase the risk of hypoglycemia.
In an animal diabetic model, zeaxanthin has hypoglycemic effects. However, population research has found that increasing intake of dietary zeaxanthin plus lutein does not decrease the risk of developing type 2 diabetes.
