For over a decade, NT Biotech (Shaanxi New Things Biotech) has been providing high quality botanical extracts to companies throughout the world that produce dietary supplements and nutraceutical products. NT Biotech is fully supported by a professional Research and Development team, an extremely stringent Quality Control System and are certified to ISO9001, KOSHER and HALAL; this is why NT Biotech's produces the highest quality ingredients that are also Stable, Traceable and Customized for each of our customers. All our pure zeaxanthin powder bulk comes from non-genetically modified marigolds, and offer an extremely pure powder, non-GMO powder, that is very flexible to use in new (modern) formulas to support good vision(eye health).

Marigold extract comes from the bright orange flowers of Tagetes erecta which belong to the rich category Carotenoid botanicals. Among these carotenoids lutein and Zeaxanthin are the two most important pigments found naturally in the macula of the human retina and both contribute to keeping your vision healthy over your lifetime.
Compared to many synthetic versions of zeaxanthin that often exist as an ester, the majority of the zeaxanthin extracted from marigold flowers is in a free form, making it more bioavailable to the body once properly processed. With the surge in natural ingredient demand, marigold flower zeaxanthin powder has rapidly emerged as one of the most popular ingredients available for eye nutrition today.
Pure zeaxanthin powder bulk has been gaining tremendous interest among supplement brands seeking demonstrably effective eye health ingredients, as digital lifestyles expose the population to increasingly greater amounts of time using electronic devices.

The human eye does not inherently create zeaxanthin. Our daily intake comes exclusively from food; but due to modern diets, we do not get enough. Thus, taking a supplement becomes an essential way to keep healthy eyesight for the long run.
Zeaxanthin boasts unique biological functions when compared with most standard carotenoids. Zeaxanthin is primarily concentrated in the macula, which is the central region of the retina used for "visual detail" (i.e., reading small print, nighttime driving, etc.).
We deliver pure lutein zeaxanthin as carotenoids that are naturally produced from marigold flowers in such a way that maintains their biological activity.
Zeaxanthin's main benefit is to protect the macular area of the retina. If you take Zeaxanthin regularly, it can help keep your vision healthy, and keep you feel comfortable when you use your device for a long time.
Blue light emitted by cell phones, computers, and LED lights is high-energy and produces oxidative stress in the retina. Zeaxanthin is a natural filter for blue light by absorbing some of the toxic blue light before it reaches your retina.
Natural blue-light protection is a major selling point for manufacturers who develop pure zeaxanthin powder bulk for eye health supplements.
Retinal cells can be harmed by free radicals that are created as we age, are exposed to UV light, are in polluted environments, and use our screens a lot. Zeaxanthin is known to be an extremely potent antioxidant; therefore, helps neutralise any existing oxidative stress, as well as facilitating proper cellular functionality.
Zeaxanthin's healthy levels can help maintain clear vision and contrast sensitivity, as well as provide comfort to the eyes of the aging population and those using their electronic devices frequently.
Consumers of today are looking for more and more plant-based and clean label dietary ingredients. Zeaxanthin extracted from marigold is a naturally derived carotenoid that will meet the needs of today's wellness products.

NT Biotech Provides Various Zeaxanthin Forms Based on Formulation Needs.
We offer concentrations of zeaxanthin powder between 5%-70% by HPLC, which are perfect for capsules and tablets as well as powder mixes and nutrition products.
We have zeaxanthin oil suspension products with concentrations of 10%, 15%, or 20% HPLC, which is very good for softgels, gummies, and oil-based dietary supplement forms.
We now offer two concentrations of zeaxanthin CWS microencapsulated powder; 5% and 10% HPLC, which are perfect for instant drinks, oral liquid drinks, gummies, fruit juices, and solid drinks; also known as products that have good water dispersion.
Now offered in 5%, 10%, and 20% HPLC, these products ensure great flow for hard capsules and compressed tablets.
In the nutraceutical industry, the eye health market is one of the fastest-growing segments, and assist manufacturers are producing more formulations for specific consumers, including:
longer screen time for adults;
visual support students during high reading times;
healthy aging for older persons;
professionals need digital eye relief;
drivers require visual relief by extended distance travel;
Lutein, bilberry extract, astaxanthin, DHA, vitamin A, zinc, and vitamins C and E are all in combination formulas that continue to drive innovation in the marketplace.
With the worldwide demand for pure zeaxanthin powder bulk increasing, many of the top eye health supplement brands have selected pure zeaxanthin powder bulk as their primary choice of raw ingredient.

Because they complement each other in the human eye, lutein and zeaxanthin are frequently seen together. They differ, however, functionally.
Lutein provides a general antioxidant protection, but it is found in different structures of the eye, whereas Zeaxanthin concentrates in the center of the macula. This makes Zeaxanthin very useful for today’s eye care products because it filters Blue Light and protects the central vision of the eye.
When both of these ingredients are combined to create a balanced formula closely resembling the natural carotenoid profile of human eyes, they produce products that are similar to the natural balance of carotenoids found in healthy human eyes. The pure lutein zeaxanthin formula has been among the most successful categories of vision supplement products available in the vision supplement market today.
Because of its good chemical stability and compatibility with other materials for use in formulations, marigold extract zeaxanthin powder is used in a variety of forms, including:
• Dietary supplements (either in capsules or as a powder)
• Hard capsules
• Softgel capsules
• Compressed tablets
• Effervescent tablets
• Gummies
• Powder Sachets
• Functional beverages (e.g., juices, teas, etc.)
• Oral liquid Formulations
• Healthy aging nutrition products
• Vision Support Complexes
• Sports nutrition products in an antioxidant position/branding.

Carotenoids must be properly stored during transportation and long-term storage to maintain their stability.
The bulk Zeaxanthin powder needs to be kept in an air tight container and no exposure to sunlight, excessive heat, oxygen and moisture.
The recommended temperature for storage of the bulk Zeaxanthin powder is below 25°C.
The typical shelf life of bulk Zeaxanthin powder in unopened original packaging under the recommended storage conditions is 24 months.
Keeping inventory rotated and protecting against moisture helps maintain bright colors and active carotenoid levels over the product's life.
