Our unique carotenoid story

Healthy eyesYour eyes are amazing!

Look after them and they’ll let you enjoy life to the full.

MacuPrime® was founded in the belief that boosting nutrition based on scientific research can be used to protect and enhance vision, helping us to live our lives in high definition and full colour.

We hold that same belief today and have stayed dedicated to carotenoid research and developing the MacuPrime®formula.


MacuPrime® explained

MacuPrime® is a food supplement.

Updated MacuPrime Packaging.

One MacuPrime® capsule contains the daily amount of the three critical macular carotenoids needed to protect your central vision.

These nutrients are delivered to the eye to rebuild the protective layer in front of the macula. The macula is responsible for over 90% of our central vision.

The protective layer that naturally gathers the carotenoids is called the macular pigment.

When working at its best, the macular pigment filters blue light, and reduces oxidative stress caused by ageing, protecting the macula from daily damage.

Long term, the macular pigment protects the eyes against Age-related Macular Degeneration (AMD) and central vision loss.


How is MacuPrime® different?

MacuPrime® is the most scientifically tested eye health food supplement in the European and UK markets. It has become the vision supplement of choice for people who are concerned about their eyesight and their risk of developing Age-related Macular Degeneration (AMD).

Your eyes suffer a daily onslaught from sunlight, blue light and oxidative stress. This breaks down the protective macular pigment. Clinical trials at Waterford Institute of Technology, in which MacuPrime® was used, have shown that we need to consume 10mg Lutein, 10mg Meso-Zeaxanthin and 2mg Zeaxanthin every day to rebuild and keep the macular pigment at it’s best. MacuPrime® is packed with this exact amount of carotenoids in a scientifically proven, safe and effective formula.

MacuPrime® has been independently tested in peer-reviewed and published clinical trials on Irish patients with healthy eyes and also those suffering from early Age-related Macular Degeneration. With full Supplement Certified certification and over 30 peer-reviewed publications demonstrating the formula’s efficacy, bioavailability and safety, MacuPrime® is a leader in eye health nutritional supplements.

Putting MacuPrime® to the test

MacuPrime® has been independently tested in numerous gold-standard clinical trials. The most significant of which were the European Research Council funded, Central Retinal Enrichment Supplementation Trials (CREST 1 and 2).

In these large-scale studies at the Nutrition Research Centre Ireland (NRCI), Waterford Institute of Technology, MacuPrime’s ingredients and formula were clinically proven to increase protective macular pigment in 100% of individuals with associated improvements in visual performance 1,2.

Continued quality control is also really important to us.  We take samples of every new MacuPrime® batch and send them to an independent lab to be checked and verified that the right amount of carotenoids are in every product.

Scientific Endorsements

We’re serious about science and have been committed to extensive research and testing from the start. Working with the very best in nutritional and vision research scientists means that MacuPrime® is supported by peer-reviewed and published science rather than just industry expert opinion.

Pioneered by its founder, the late Dr Alan Howard, The Howard Foundation has sponsored the decade of clinical trials at Waterford Institute of Technology, Ireland into the benefit of macular carotenoids on visual function.

The Howard Foundation takes pride in its many research patents on visual performance and cognition. It endorses MacuPrime® as being the primary eye health supplement in Europe and the UK resulting from this research and these patents.

Speaking of this endorsement, Jon Howard, Secretary of the Foundation comments,

The Howard Foundation is delighted to recommend MacuPrime – a product that has the highest quality and efficacy, tested in world renowned clinical trials and proven to be effective in rebuilding macular pigment, improving visual function and protecting against Age-related Macular Degeneration (AMD), the leading cause of vision loss in people aged 50 and older.”
