Of the hundreds of carotenoids found in nature, only lutein and zeaxanthin concentrate naturally in the macula, the retina’s central zone responsible for fine detail vision. These xanthophylls act as a biological filter, absorbing part of the blue light from screens, sunlight and artificial lighting, contributing to macular pigment density — a recognised marker of visual comfort. The body cannot make these pigments itself; they must come from diet or supplementation.

Regular lutein and zeaxanthin intake supports the maintenance of normal vision, particularly in bright light or with prolonged screen exposure, and contributes to antioxidant protection of retinal cells against oxidative stress. The 10mg/2mg ratio matches the dosing most used in reference eye-health studies, particularly relevant for adults from their forties onward. Marigold (Tagetes erecta) is the richest known plant source of free lutein; petals are gently extracted with no harsh solvents, preserving the natural molecular structure associated with retinal tissue affinity.

The AREDS2 study (Age-Related Eye Disease Study 2), run by the US National Eye Institute on over 4,000 participants, highlighted the value of 10mg lutein and 2mg zeaxanthin supplementation for macular health. Further nutrition and ophthalmology research confirms these carotenoids raise macular pigment optical density (MPOD), a measurable marker of the eye’s blue-light filtering capacity — doses below 5mg lutein showed no significant results in most studies, supporting the 10mg dose used here.

Take 1 capsule a day, ideally with a fat-containing meal, since lutein and zeaxanthin are fat-soluble and absorb much better with dietary fats (olive oil, avocado, oily fish, nuts) — taking it on an empty stomach considerably reduces bioavailability. Maintain supplementation for at least 2–3 months to see initial effects on macular pigment density; a 60-capsule bottle covers a full 2-month cycle.

For adults. If pregnant, breastfeeding, or on medication, seek advice from a healthcare professional before use. Do not exceed the recommended daily dose. Store in a cool, dry place away from light, out of children’s reach.

Why combine lutein and zeaxanthin?

Both are present together in the human macula — lutein concentrates mainly at its periphery, zeaxanthin at its centre. Combining them mirrors this natural distribution for full macular pigment coverage.

Is it suitable for vegans?

Yes — the formula is entirely plant-based: lutein and zeaxanthin from marigold petals, a pullulan capsule shell, and organic acacia fibre as the only excipient. No animal ingredients, gluten or lactose.

Can it be combined with other eye-health nutrients?

Yes — zinc, omega-3 (DHA) or vitamin E are often paired with lutein and zeaxanthin; ask a healthcare professional to tailor dosing to your situation.
