Supplement · Grade B

Lutein and medications.

Not yet catalogued in the Distil interactions database. We surface that distinction explicitly.

Lutein is in the Distil supplement database, evidence Grade B. The page below lists every medication we have explicitly assessed it against.

Lutein is a carotenoid pigment, usually paired with zeaxanthin, that concentrates in the macula at the back of the eye. There it filters blue light and acts as an antioxidant inside the retina, which is the basis for its use in eye health. The evidence is Grade B, and it is worth being precise about what it does and does not show, because this is a heavily marketed supplement. The better-supported half is visual performance, though it is narrower than it first looks: the double-masked placebo-controlled trial that met its pre-specified contrast-sensitivity endpoint enrolled people who were free of retinal disease but who already had low macular pigment, so it shows what happens when a low level is topped up rather than what happens in a well-nourished eye. It was also small, it measured a visual-function surrogate rather than a hard outcome, and its formula contained a third carotenoid, meso-zeaxanthin, alongside the lutein and zeaxanthin. On age-related macular degeneration the picture is genuinely two-sided. As the carotenoid within the full AREDS2 formulation it is supported, and it is the appropriate substitute for beta-carotene, which carries a lung cancer signal. As a standalone supplement added for someone who already has macular degeneration, a Cochrane review found it may have little or no effect on progression. Family history alone is not a reason to start it; that is a reason to raise eye screening with a GP. The usual dose is 10 to 20mg lutein with 2mg zeaxanthin, the AREDS2 ratio. There are no significant drug interactions. Because it is fat-soluble, it absorbs better taken with fat-soluble vitamins or a meal containing fat. At very high doses the skin can turn slightly yellow, which is harmless and reverses on stopping.

We have not yet completed an explicit assessment of medications for Lutein in the Distil interactions database. We surface this distinction deliberately: the Distil checker tells you when we have explicitly assessed a pair and when we have not, because both are useful information. If you take Lutein alongside a medication, the checker below will surface anything already in our database, and the missing-item form at the bottom of the page routes uncatalogued pairs into our next curation pass.

What this list does not say. Pairs not flagged here are not implicitly safe. They are either not yet in our database, or fall outside our inclusion scope. Use the checker below to surface any medication, and submit a missing item if you take something we have not catalogued.

How we decide

How we grade severity, choose what's in scope, and what we exclude.

Every call on this page is reasoned. We publish the full rubric for severity tiers, the medication inclusion logic, the evidence grades we accept, and what we deliberately leave out. About three thousand words. Worth reading once if you use this tool more than occasionally.

The full report

A full supplement review, built around you, not a generic stack.

The free checker answers one interaction question at a time. A Distil report reviews the bigger picture: your goals, diet, medications, current supplements and any blood results you provide, then shows what appears worth keeping, changing, adding or leaving out.

what your diet already covers, so you are not adding a capsule for something food is already handling
which evidence-graded compounds are worth considering for your goals, and which were considered but left out
what to keep, change or stop from what you already take, plus the order to introduce anything new
how your medications and complete supplement stack fit together, with daily timing and a clear point for reassessment

The interaction check is one section of the full report. You also get the reasoning behind each recommendation and the evidence references used.

Something missing?

If a supplement or medication you take isn't in our autocomplete, tell us. We go through what people flag every week and add what's missing.

Thanks, that's logged. We go through flagged items every week.

Distil's interactions database is reviewed and updated every quarter. We grade evidence transparently and publish our methodology, including every database change, at /about/methodology. This tool is information, not a substitute for clinical judgement. If you take medication and supplements together, your GP or pharmacist can review your full regimen against your medical history. If you want a full personalised stack reasoned against this same database, the Distil report is the next step up.
