MacuHealth Plus+

MacuHealth Plus+ is a premium eye supplement that stands apart by delivering all three macular carotenoids — lutein, zeaxanthin, and meso-zeaxanthin — in a patented formula backed by research from the Waterford Institute of Technology. For adults over 50 who want the most comprehensive macular pigment support available, this triple-carotenoid approach addresses a gap that most mainstream eye supplements miss entirely.

What Is MacuHealth Plus+?

MacuHealth was developed based on research led by Professor John Nolan and his team at the Nutrition Research Centre Ireland (NRCI), part of the Waterford Institute of Technology in Ireland. Their work focused on a simple but important question: the macular pigment contains three carotenoids, so why do most supplements only provide two?

The three carotenoids in the macular pigment are lutein, zeaxanthin, and meso-zeaxanthin. Lutein and zeaxanthin are found in many foods and are included in virtually every eye supplement. Meso-zeaxanthin, however, is concentrated at the very center of the fovea — the point of sharpest vision — and is almost absent from the typical Western diet. Most supplement makers skip it because it is harder to source and more expensive to include.

MacuHealth Plus+ is the company’s enhanced formula that combines the triple carotenoid blend with additional antioxidants. The “Plus+” version adds vitamin C, vitamin E, zinc, and copper alongside the three carotenoids. The standard MacuHealth product contains only the three carotenoids without these extras.

What’s Inside

Each daily capsule of MacuHealth Plus+ contains:

• Lutein 10mg — The dominant carotenoid in the peripheral macula, responsible for filtering blue light before it reaches photoreceptor cells. Sourced from marigold flower extract.
• Meso-zeaxanthin 10mg — The carotenoid concentrated at the foveal center. This is the ingredient that distinguishes MacuHealth from nearly every competitor. Derived from marigold-sourced lutein through a patented conversion process.
• Zeaxanthin 2mg — Concentrated in the mid-peripheral macula, bridging the lutein and meso-zeaxanthin zones.
• Vitamin C 500mg — Antioxidant protection for retinal tissues.
• Vitamin E 400 IU — Fat-soluble antioxidant supporting cell membrane integrity in the retina.
• Zinc 25mg — Supports retinal enzyme function. Notably, this is a lower dose than the 80mg in AREDS formulas, which reduces the risk of stomach upset.
• Copper 2mg — Prevents zinc-induced copper depletion.

The 10:10:2 ratio of lutein to meso-zeaxanthin to zeaxanthin reflects the natural composition of the macular pigment as measured in healthy eyes.

What the Research Says

The Waterford group has published extensively on macular carotenoids. A key study published in Experimental Eye Research in 2012 demonstrated that supplementation with all three carotenoids increased macular pigment optical density (MPOD) more effectively than lutein and zeaxanthin alone. The meso-zeaxanthin component was responsible for enriching the central foveal pigment specifically.

A 2016 randomized controlled trial published in Investigative Ophthalmology & Visual Science (the CREST study) found that subjects taking the triple carotenoid formula experienced significant improvements in MPOD, contrast sensitivity, and glare disability after 12 months. These functional outcomes go beyond simply measuring pigment — participants reported real differences in how well they could see in challenging conditions like bright light and low contrast.

A separate 2014 study in Eye found that many patients with AMD had undetectable levels of meso-zeaxanthin in their macular pigment, even when lutein and zeaxanthin levels were normal. This suggests that the central macular pigment may be a specific vulnerability in AMD — one that only meso-zeaxanthin supplementation can address.

The evidence for MacuHealth is promising but carries an important caveat: these studies are smaller than the AREDS trials and use surrogate endpoints (MPOD, contrast sensitivity) rather than disease progression. The AREDS2 study enrolled over 4,000 participants and measured actual AMD progression over years. MacuHealth’s supporting research, while rigorous, operates at a different scale.

Who Is This Best For?

MacuHealth Plus+ is a strong choice if you:

• Want the most comprehensive macular pigment support and are willing to pay for the only supplement that provides all three carotenoids
• Have normal or early-stage macular health and want to build robust macular pigment density proactively
• Experience glare sensitivity or reduced contrast vision — the CREST study showed improvements in these specific symptoms
• Have a family history of AMD and want to go beyond basic lutein supplementation
• Cannot tolerate high-dose zinc — the 25mg dose in MacuHealth Plus+ is much gentler than the 80mg in AREDS formulas

This may not be the best fit if you:

• Have diagnosed intermediate or advanced AMD — your ophthalmologist will likely recommend the AREDS2 formula first, since it has stronger disease-progression evidence
• Are on a tight budget — at $45 for 90 capsules, this is one of the more expensive eye supplements
• Prefer to buy in-store — MacuHealth has limited retail pharmacy distribution and is primarily sold online or through eye care professionals

How to Take It

Take one capsule daily with a meal containing dietary fat. The carotenoids are fat-soluble and need fat present in the gut for proper absorption. A meal with eggs, olive oil, avocado, or nuts is ideal.

Consistency matters more than timing. Pick a meal you eat reliably every day and pair the capsule with it. Building macular pigment is a slow process — expect 3 to 6 months before measurable changes in MPOD.

Supplement stacking note: MacuHealth Plus+ contains 500mg vitamin C, 400 IU vitamin E, and 25mg zinc. If you also take a multivitamin, check for overlap on these nutrients. The zinc level is moderate enough that combining with most multivitamins stays within safe limits, but vitamin E can add up quickly. Bring your full supplement list to your pharmacist for a quick check.

The Bottom Line

MacuHealth Plus+ is the most scientifically thorough macular pigment supplement on the market. The inclusion of meso-zeaxanthin — the third and often-missing carotenoid — addresses a genuine gap in most eye health formulas. The research is compelling, if not yet at the scale of the AREDS trials. For adults over 50 who prioritize comprehensive eye protection and can afford the premium price, this is a standout option.

Always consult your doctor before starting any new supplement, especially if you have existing eye conditions or take prescription medications.
