Understanding macular carotenoids 

Carotenoids are natural plant pigments that give fruits and vegetables their vibrant colours, from the deep green of kale to the golden yellow of egg yolks. While there are over 700 carotenoids found in nature, only three, lutein, zeaxanthin, and most importantly meso-zeaxanthin are of special interest because they are naturally found in the eyes and brain. 

In the eyes, light enters and is focused on the retina at the back of the eye. Here lies the macula, a part of the eye that provides sharp vision, allowing us to read, drive, and recognise faces easily. The macula is protected by a yellow layer known as the macular pigment, which is made up of the three macular carotenoids: lutein, zeaxanthin, and, as shown by scientific research, meso-zeaxanthin, the epicentre of this layer. 

Where carotenoids come from 

Carotenoids help plants harness the energy from the sun and naturally protect plants as they grow. However, modern farming practices, like heavy use of fertilizers, pesticides and artificial light, have led many crops to evolve with lower carotenoid levels. That’s why the source of your fruits and vegetables matters: home-grown or organic produce is usually richer in these nutrients than mass-grown alternatives. 

Two of these three carotenoids are readily available from a variety of foods. Dark leafy greens like kale and spinach are excellent sources of lutein and zeaxanthin. Egg yolks provide a rich, easily absorbed form of these nutrients. Other vegetables, such as corn and red or yellow peppers also contribute to your carotenoid intake.  Meso-zeaxanthin, the most critical carotenoid, is nearly impossible to find in natural foods and has only been found in trout fish skin. While many people can convert lutein into meso-zeaxanthin in the eye , research from the NRCI shows that 12% of the population cannot do this efficiently. That’s where knowing your carotenoid level and carotenoid supplementation plays a key role. Even with a balanced diet, carotenoid intake can vary day-to-day, and some people may not get enough  consistently.

Carotenoids in supplements 

Supplements like ReMind provide lutein, zeaxanthin, and meso-zeaxanthin in a highly purified form. These nutrients are carefully extracted from organic marigold flowers grown in Mexico, where they are naturally abundant. By including them in your daily routine, supplements can help ensure you consistently get these nutrients, complementing a balanced diet. 

ReMind’s formulation provides a convenient, reliable source of  carotenoids that have been scientifically researched and tested, supporting overall carotenoid intake

Why understanding carotenoids matters 

Knowing what carotenoids are, where they come from and why their source matters help you to make smarter choices about your diet and nutrition.  Eating a variety of colourful, nutrient-rich foods is important but so is getting these nutrients consistently and choosing high-quality sources. By combining a balanced diet with a high-quality supplement like ReMind, you can support your daily intake of these naturally occurring pigments.
