HelloPharmacist Scorecard of Lutein 20 mg by Source Naturals

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 13, 2026

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.
  • “Marigold Flower Extract” is listed as a grouped ingredient — the label gives one combined amount (400 mg) without saying how much of each component you get.

This product contains two active ingredients: zeaxanthin and lutein, both carotenoids found naturally in your diet. Zeaxanthin and lutein concentrate in the eye, especially in the macula (the central part of the retina), where they filter harmful light and work as antioxidants.

The capsule also contains gelatin as an inactive 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, Conjunctivitis — 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).

Zeaxanthin is possibly effective for age-related macular degeneration (AMD). Lutein is possibly effective for both AMD and cataracts.

For other conditions in the facts — including age-related cognitive decline, Alzheimer disease, asthma, and several eye or lung conditions — the evidence we hold is either insufficient or shows these ingredients are possibly ineffective.

The evidence, ingredient by ingredient Calendula Zeaxanthin Lutein

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.

Both zeaxanthin and lutein are generally well tolerated at typical supplement doses. Lutein at doses up to 20 mg daily has not caused adverse effects in trials.

For pregnancy and breastfeeding, both ingredients are rated Likely Safe, though the safety data on concentrated supplement doses during pregnancy and lactation is limited — food sources are fine, but if you're pregnant or breastfeeding, talk with your doctor or pharmacist before taking this supplement to make sure it fits your situation.

Side effects, ingredient by ingredient Calendula Zeaxanthin Lutein

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 2 matched ingredients can interact with medications — Zeaxanthin.
  • 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.

If you take an antidiabetes drug (like metformin, insulin, or a sulfonylurea), double-check with your doctor or pharmacist before starting this product — zeaxanthin may increase the risk of low blood sugar.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may be worth considering if you're concerned about age-related macular degeneration or cataracts. If you take a diabetes medication, check with your doctor or pharmacist first — zeaxanthin can theoretically lower blood sugar further.

Pregnant or breastfeeding individuals should confirm with their own healthcare provider that a concentrated supplement makes sense for them.

FDA Statement of Identity

Dietary Supplement

Formula

Antioxidant carotenoid

Lutein is a potent antioxidant carotenoid found in abundance in green leafy vegetables. Lutein is also one of the dominant pigments found in the macular region of the retina in the eye. In the macula, lutein is selectively accumulated from plasma and filters out visible blue light and ultraviolet light. This filtering process serves to protect the retina from photic damage or other oxidative damage.

Cns Depressants

Theoretically, calendula might have additive effects when used with CNS depressants, although this appears to be unlikely.
Although some animal research has suggested that a saponoside constituent in calendula may have sedative effects, calendula has been used for over 30 years without reports of sedation in humans.

Lutein 20 mg by Source Naturals: Common Questions

Does Lutein 20 mg by Source Naturals interact with any medications?
Yes. Based on its ingredients, Lutein 20 mg has a known interaction with 334 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Lutein 20 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What's the difference between zeaxanthin and lutein?
Both are carotenoids that concentrate in your eye's macula, but they're different compounds. Zeaxanthin is possibly effective for AMD; lutein is possibly effective for both AMD and cataracts. You need both for full eye protection, which is why they're often paired in supplements.
Will this help my cataracts?
Lutein in this product is possibly effective for cataracts, so there's evidence it may help. Zeaxanthin's role in cataracts isn't rated in our data. Talk with your eye doctor about whether this supplement is right for your specific situation.
Is it safe to take while I'm breastfeeding?
Both ingredients are rated Likely Safe, but the safety data on concentrated supplement doses during breastfeeding is limited — food sources are fine. Check with your doctor or pharmacist to make sure a supplement is the right choice for you right now.
What dose of lutein is in here, and is it safe?
This product contains 20 mg of lutein daily. Lutein at this dose has not caused adverse effects in trials and is generally well tolerated.
Does this product have any fillers?
It contains gelatin as an inactive ingredient in the capsule. The active ingredients are zeaxanthin and lutein.
I have type 2 diabetes — is this safe for me?
Zeaxanthin in this product may theoretically increase your risk of low blood sugar if you take a diabetes medication. Talk with your doctor or pharmacist before starting it to make sure it's safe for your individual situation.
