HelloPharmacist Scorecard of Double Strength Luteiin 20 mg by NOW
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.
What’s inside
Full disclosure
This product contains one active ingredient: lutein 20 mg per capsule. Lutein is a carotenoid found in leafy greens and other plants; your body stores it in the eye, where it may help filter harmful light.
The capsule also holds inactive ingredients — cellulose, stearic acid, beet powder, and ascorbyl palmitate — which are fillers and binders.
Does it work?
Moderate evidence
Lutein is possibly effective for age-related macular degeneration (AMD) and cataracts, according to the evidence we have. For other conditions — retinitis pigmentosa, retinopathy of prematurity, necrotizing enterocolitis, and bronchopulmonary dysplasia — the evidence suggests it's possibly ineffective.
The research on lutein for eye health is ongoing, so talk with your eye doctor about whether it fits your needs.
How safe is it?
Well-documented data
Lutein at 20 mg daily — the dose in this product — is generally well tolerated with no adverse effects reported in trials. The caution here is that most safety data comes from dietary sources and lower supplement doses; higher supplement doses haven't been as thoroughly studied.
Lutein is naturally present in breast milk, but safety of higher supplement doses during breastfeeding isn't well established, so check with your doctor if you're nursing. For pregnancy, the data rates lutein as likely safe.
Meds to double-check
No known interactions
No interactions are documented for lutein in our data. Still, run this product through the interaction checker on this page with your exact medications, or ask your pharmacist to confirm there are no concerns.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
NOW Double Strength Lutein is a straightforward product for anyone interested in eye health support, especially if you're concerned about macular degeneration or cataracts. The 20 mg dose is well tolerated, though the evidence for effectiveness is modest.
If you're pregnant, nursing, or take regular medications, a quick conversation with your doctor or pharmacist before starting is a good idea.

General Statements
Lutein is an orange-red carotenoid pigment produced by plants and is present in the diet in colorful fruits and vegetables. In the body, Lutein is one of the predominant pigments concentrated in the macula, a specialized area of the eye that is responsible for central vision. In addition, it is known to be deposited in the skin. Lutein's functional role in these vulnerable tissues is to protect against sunlight-induced free radical production.
