HelloPharmacist Scorecard of Lutein 20 mg by 21st Century

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

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 1 of its 1 active ingredient.
  • “Lutein” is listed as a grouped ingredient — the label gives one combined amount (20 mg) without saying how much of each component you get.

This product contains one active ingredient: zeaxanthin, a carotenoid (a type of plant pigment) that works alongside related compounds to support eye health. The softgel also contains inactive ingredients — sunflower oil, gelatin, glycerin, beeswax, purified water, and soy lecithin — which help deliver the active ingredient.

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 health and macular 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: Zeaxanthin is rated "Possibly Effective" for Age-related macular degeneration (AMD) (Natural Medicines).
  • Also on file: Zeaxanthin is rated "Insufficient Reliable Evidence To Rate" for Cataracts, Glaucoma, Asthenopia (eye strain), Macular telangiectasia type 2.

Zeaxanthin is possibly effective for age-related macular degeneration (AMD), the most common cause of vision loss in older adults. The evidence isn't established in our data for its use in age-related cognitive decline, Alzheimer disease, asthma, breast cancer, or bronchopulmonary dysplasia.

The evidence, ingredient by ingredient Lutein Zeaxanthin

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Zeaxanthin is generally well tolerated at typical supplement doses. Dietary amounts from food are safe during pregnancy and breastfeeding, but because supplement safety in pregnancy and lactation hasn't been well studied, talk with your doctor or pharmacist before taking a concentrated supplement if you're pregnant or breastfeeding.

Meds to double-check

Known Interaction Concern · database check

Why this rating?

  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.
