What is Marigold Extract?
Marigolds are a group of common ornamental flowers, grown around the world for their bright orange, yellow and red petals. It is these distinct colours that also make them interesting for nutrition. What gives plants like marigold their colour is a group of pigments called carotenoids, and marigold petals are a rich source of two of them, lutein and zeaxanthin.
The human retina is a layer of light-sensitive cells on the back wall of your eyeball. At its centre sits the macula, which contains a yellow pigment known as 'the macular pigment'. This pigment absorbs blue light before it reaches the light-sensitive cells beneath, acting a bit like a natural sunscreen. Lutein, zeaxanthin and meso-zeaxanthin are the key components of this pigment. Meso-zeaxanthin is made from lutein, and marigold is the usual source.
What does the research say about Marigold Extract?
Researchers have looked at lutein and zeaxanthin intake in relation to how the macula changes as we age. They have also studied nutrition in relation to blue light and long hours of screen use, the light given off by artificial lighting and devices like smartphones and computer screens.
Carotenoids, including those found in marigolds, are also a source of antioxidants in the diet. This means they 'scavenge' and neutralise unstable molecules called 'free radicals'.

Pumpkin
Pumpkin contains a variety of vitamins and nutrients with excellent health benefits, especially for our eyes.
Vitamin A
Vitamin A is vital for our immune system, fighting off infections and in the production of white blood cells. It is also essential for healthy skin, vision and eye health.
Vitamin B2
Vitamin B2 is an antioxidant, a compound that keeps the number of unstable molecules (known as ‘free radicals') at a healthy level in the body.
Vitamin E
One of Vitamin E’s main benefits is that it acts as an antioxidant. Antioxidants combat harmful ‘free radicals’ (unstable molecules), helping prevent damage to cell membranes.
Algae
Algae is one of the main starting points for omega 3 in the food chain and is the source of our Vegan Omega 3, vital for our heart, brain and eye health, and much more.
Astaxanthin
Carotenoids - Lutein, Zeaxanthin, Meso-zeaxanthin and Astaxanthin - are found at the back of the eye, forming the macular pigment which is so important to protect for long-term vision.
Beta Carotene
Beta-carotene is a carotenoid that gives carrots their distinctive colour. Our body converts it into Vitamin A for a range of health benefits, particularly for our eyes.
Bilberry
Bilberry is an antioxidant, supporting the retinal function, helping maintain eye health, and providing a natural defence against free radicals.
