Lutein is Not Enough On Its Own – The Power of Three Carotenoids Is Needed




Lutein is a nutrient that is often recommended for eye health.  However, recent science has shown that Lutein on its own is not enough to rebuild the protective macular pigment at the back of the eye.

To achieve optimum results you need the power of three carotenoids, Clinical studies have tested the MacuPrime triple carotenoid formula against formulations with just Lutein. It was found that when we combine Lutein with Zeaxanthin and Meso-Zeaxanthin, the three nutrients together deliver the best results.

Can Diet affect your eyesight?
What are Lutein, Zeaxanthin, and Meso-Zeaxanthin?

Lutein, Zeaxanthin, and Meso-Zeaxanthin are plant-based nutrients called carotenoids. Carotenoids are the natural pigments that give vegetables, fruits, and other plants their colour (red, orange, yellow, and green). Carotenoids are not produced by the human body, meaning we need to consume them through our diet. 

All three of these nutrients are found in high concentrations in the macula of the human eye. In our diet they are found in dark-green leafy vegetables, colourful fruits and fish. The macula, a small  area at the centre of the retina that contains the highest concentration of photoreceptor cells, is a very important part of the eye. It gives us all of the fine and detailed vision we need for precision tasks such as reading and writing, seeing faces, as well as our colour vision. In fact, lutein, meso-zeaxanthin and zeaxanthin each contribute to the macula’s yellow colour.


Why are Zeaxanthin and Meso-Zeaxanthin so important?

The area where carotenoids gather in our eye is called the macular pigment. This yellow protective layer protects the macula from damage. When working at its best, the macular pigment filters blue light, and reduces oxidative stress caused by ageing, protecting the macula from daily damage. For years scientists thought Lutein was the only carotenoid to gather at the macular pigment. However, recent studies at Nutrition Research Centre Ireland have proven that the macular pigment is in fact made up of Lutein, Zeaxanthin and Meso-Zeaxanthin.

Consider  Zeaxanthin, Meso-Zeaxanthin and Lutein as an essential wall, complete with building blocks and cement. Lutein is the foundation, Zeaxanthin is the blocks and Meso-Zeaxanthin is the cement. These three carotenoids work together in synergy to deliver powerful antioxidant and anti-inflammatory protection to  rebuild the macular pigment at the back of the eye. This synergistic benefit was proven in the Central Dip Clinical Study at NRCI where it compared patients taking MacuPrime with all three carotenoids versus groups taking just Lutein or a combination of Lutein and Zeaxanthin. MacuPrime provided the best results over 3, 6 and 12 month periods.

MacuPrime gives essential nutrients to the eye when taken once a day, helping to repair the protective layer in front of the macula. Long term it protects the eyes against Age-related Macular Degeneration (AMD) and central vision loss.

How can I get Lutein, Zeaxanthin, and Meso-Zeaxanthin in my Diet?

A healthy diet, high in antioxidant vitamins and minerals has long been associated with the prevention or delay of AMD. Dark-green leafy vegetables, eggs and fruit are a good source of Lutein and Zeaxanthin.

However, it is really difficult for us to consume Meso-Zeaxanthin through our diet as it is only available in trout skin. So boosting your diet with a daily carotenoid supplement, such as MacuPrime, is an easy way to make sure you are getting the recommended 10mg Meso-Zeaxanthin as well as 10mg Lutein, and 2 mg Zeaxanthin for good macular health.

Did you know? 

You would need to eat 1.7 cups of kale, 11,904 whole trout and 1.8 cups of orange pepper every day, to get the recommended daily carotenoid dose  (10mg Lutein, 10mg Meso-Zeaxanthin and 2mg Zeaxanthin) that has been proven in clinical research studies to be effective in rebuilding macular pigment. 

Taking a daily MacuPrime capsule gives you a simple and easy way to nourish your macular pigment with the ideal dose of triple carotenoids.
