Lutein Powder Bulk

Lutein Powder Bulk is a high-grade, scientifically proven carotenoid with a strong antioxidant effect, which is considered the "gold standard" in the nutritional eye health and anti-progressive wellness market. Lutein is naturally occurring in the marigold flower and dark leafy greens; it is an important biological filter in the human body. It has the ability to be selectively concentrated in the macula of the retina and the brain tissue when consumed, and it is able to absorb the harmful high-energy blue light from the digital screen and neutralize the harmful oxidative free radicals. Regular supplements of high-purity lutein powder have been shown in clinical studies to reduce the risk of age-related macular degeneration (AMD), ease digital eye strain, and improve cognitive function and skin photo-protection. It is particularly advantageous for manufacturers and formulators in the nutraceutical and functional food segment due to its excellent thermal stability, solubility, and compatibility with various delivery systems including hard capsules, tablets, and beverage formulations. Adding it to product lines ensures that brands meet high consumer demand and are able to provide evidence-based health claims, serving the growing, global population of digital wellness, eye care, and healthy aging.

1. Marigold Flower Harvesting & Pretreatment:

Marigold flowers (Tagetes erecta) are premium and grown in an environmentally friendly way, then cleaned mechanically, dried under controlled conditions, and milled to achieve sufficient reduction in particle size for maximum extraction.

2. Solvent Extraction:

The milled marigold meal is processed by food-grade solvent extraction (usually hexane) to extract the crude oleoresin containing the natural lutein esters and other valuable carotenoids.

3. Saponification:

The crude extract is treated with an alkali solution to break down the lutein esters to obtain the free lutein molecules and adjust the concentration profile to the strict purity requirements.

4. Crystallization & Purification:

The saponified mixture is subjected to the process of fractional crystallization and multi-stage filtration to isolate pure lutein crystals from the fatty acids, waxes, and impurities.

5. Drying, Blending & Micronization:

The purified Crystalline Lutein is dried under vacuum conditions and added to the blend to achieve precise potency standards (e.g., 5% to 80%) and micronized for its superior physical consistency and dispersion properties.

6. Quality Control & Packaging:

All batches are analysed in detail, with HPLC assay for potency, heavy metals and microbial testing, and then hermetically packaged under a nitrogen atmosphere in oxygen-barrier film for optimum stability and shelf-life.

The right Lutein Specification will depend on the type of delivery system, the manufacturing specifications, and the application (nutraceuticals, functional foods, beverages, cosmetics).

The following table provides the standard specifications for lutein at various concentrations and their typical industrial uses:

Application Recommendations

For Beverages & Dietary Drink Mixes (5% – 10%):

Use lower specifications with properties of "cold water-soluble" (CWS) or "microencapsulated" to provide clear or uniform suspension without clumping or precipitation, as in the case of some higher specification products.

For Capsules & Tablets (20% – 60%):

They are the best compromise in terms of active content and physical processing properties (bulk density, powder flow) and are suitable for high-speed automated encapsulation and tableting.

For Advanced Formulations & Softgels (80% – 90%):

When space for the formula is extremely limited or when trying to create high-end, top-of-the-market wellness products requiring maximum active density, use high-purity crystalline grades.

Q: What is the main source of Kingsci's lutein powder?

A: Our lutein powder is naturally extracted from high-quality Tagetes erecta marigold flowers that are grown in a controlled agricultural environment, which assures high active purity and consistency.

Q: What is the difference between lutein esters and free lutein in your powders?

A: In plants, lutein is naturally bound to fatty acids as lutein esters, which are well-stable. Free lutein can be achieved by saponification, and it is directly bioavailable and absorbed from the food without being digested in the body. Available specifications customized for formulation.

Q: Are your lutein powder products water-soluble?

A: Standard crystalline lutein is fat-soluble. We also offer special cold water soluble (CWS) / microencapsulated grades for uniform and clear dispersion in solid beverages, protein drinks, and liquids.

Q: What is the standard minimum order quantity (MOQ) and shelf life?

A: As for the minimum order quantity, we are flexible to support the pilot run and commercial production starting from 1kg (typically) for small batch sizes up to 25kg (typically) for bulk drums. It has a shelf life of 24 months under cool, dry conditions, away from direct light, in the original, unopened packaging.

Q: Do you support custom formulations and OEM/ODM packaging?

A: Yes. We have more than 18 years of experience and provide full OEM/ODM service, providing you with customized specifications, specific carrier blends, and private label packaging solutions that suit your brand requirements.
