Marigold extract lutein powder is extracted from Marigold flowers which have been selected using specialized extraction methods in conjunction with saponification and purification processes to produce the highest level of bio-available free Lutein. At present we provide full specifications from UV 80% 85% 90% to HPLC 5% 10% 20% 80% 90% with 10% & 20% being the most popular choices for dietary supplement & functional food manufacturers.

Marigold extract lutein powder can be described as the carotenoid pigment found naturally in marigold flower petals (Tagetes erecta). The preparation of the marigold extracts involves a process of extraction, which is followed by saponification of the naturally occurring Lutein esters in the marigold flower extract to form a more stable, readily-absorbable form of Lutein.
Compared to synthetic lutein, which is generally manufactured through chemical means, natural lutein from marigolds is created from a single plant source, and has an excellent consumer appeal for those who are searching for natural, "clean-label" nutritional products. Since humans can't produce lutein internally, either diet or supplementation is critical to supply sufficient amounts of lutein to keep the body at optimal levels of lutein.
With the increasing knowledge of eye health among the global population, lutein extract powder has become one of the most popular ingredients in eye health supplements, healthy aging formulations, children's nutrition products, and animal feed additives globally.

NT Biotech's Marigold Extract Powder provides an excellent quality and consistent performance in the manufacture of, Capsules, Gummies, Tablets, Beverages, and Animal Nutrition Products.

The manufacturing process has a direct impact on the pure state of lutein and its biological efficiency.
The main stages of our manufacuturing process are as follows:
- Selection of suitable marigold flowers
- Use of natural solvents to obtain lutein ester extract.
- Saponification is done in a controlled manner to convert lutein esters into free lutein.
- Removal of impurities using advanced purification technology.
- Preparation of dry powders using exact methods of drying.
- The final product undergoes laboratory testing before shipment.
It will be a great benefit of that manufacturing process to improve product stability, and it will help to increase the bioavailability of free lutein as compared to the lutein ester form.
Lutein is part of the carotenoid family and is a great antioxidant.
Marigold extract lutein powder can:
Lutein extract powder can be used with Vitamin C, Vitamin E, Astaxanthin, Zeaxanthin, and many other functional ingredients by manufacturers creating antioxidant types of formulas.
Consumers are turning to more naturally-focused ingredients than those made synthetically.
The lutein in our marigold extract has a few basic benefits that include the following:
With all of these benefits, this marigold extract powder product makes for a great addition for high-quality supplement companies to!

Lutein identified naturally within the marigold blooms will exist in the form of lutein esters. By regulating saponification, the esterified lutein converts to the free lutein, which makes it easier for the body to digest and absorb. Higher bioavailability, therefore, explains why free lutein now represents the lutein of choice in most modern dietary supplement formulations.
The superior safety profile and physiological functions of marigold extract powder allow this product to be used in many different industries.
Eye health dietary supplements are marigold extract powder's biggest use.
Typical dosage forms for eye health supplements include the following:
There are many eye health supplements containing lutein that also contain zeaxanthin, bilberry extract, DHA, Vitamin A, Vitamin C and Vitamin E.
Food manufacturers use lutein in:
Because it is naturally sourced, lutein also serves as a clean-label nutritional ingredient.
Lutein is a Natural Food Colourant approved as E161b
Lutein provides a bright yellow-orange colour to many food items including:
Marigold extract lutein powder is naturally occurring in contrast to artificial dyes and consumers prefer more natural products in today's marketplace.
The feed business is another significant location for using the Lutein pigment.
Lutein is applied in:
- Poultry feed
- Egg yolk pigmentation
- Aquaculture feed
- Pet nutrition
The benefits of Lutein in animal industry are:
- Improved skin pigmentation in poultry
- Improved egg yolk color
- Improved coloration of aquatic animals
- Increased market value of animal products

Lutein and zeaxanthin are two closely related carotenoid compounds that generally work together synergistically.
Lutein has a more even distribution in the retina, while blue light filtration and antioxidant protection are its primary functions. Zeaxanth is found mainly in the central macula and is responsible for providing additional support to maintain central vision.
Lutein and zeaxanthin do not compete with each other, but complement each other and brand formulas of vision supplements include both lutein and zeaxanthin as ingredients to provide complete nutritional support to the eyes
Manufacturers looking for unique products can mix lutein with zeaxanthin. This combination brings extra benefits for consumers.
Absolutely Yes.
The natural lutein extracted from marigold flowers has been used in many dietary supplements, foods and animal feed applications for many years.
Since lutein occurs naturally in vegetables (spinach and kale), it has become practical to supplement with lutein on a daily basis to improve your daily dietary intake (especially when your diet is low in vegetables or when you're exposed to high levels of screens).
The processes we use for producing our Marigold Extract Lutein Powders have all of the following process controls:
- Natural Botanical Sourcing
