Marigold extract lutein 20% for eye supplement
What is Marigold Lutein?
Marigold Lutein Bulk Powder is a pure natural carotenoid extract refined from high-quality Tagetes erecta (marigold flower) raw materials. As a factory-direct bulk raw material, it adopts GAP-standard planted marigold petals, processed through low-temperature drying, physical extraction, purification and spray-drying technology, no chemical additives, pure natural and safe.Different from synthetic lutein, our plant-derived lutein has better human body absorption and higher food safety.
The product is fine orange-yellow crystalline powder, uniform color, no caking, good water solubility and oil solubility (customizable water-soluble/oil-soluble models). It has a slight natural plant fragrance, no peculiar smell, stable chemical properties, not easy to oxidize and deteriorate.
KH Health supplies lutein bulk powder standardized to 20% free lutein, extracted from cultivated marigold flowers under controlled conditions.
Why Source Lutein from a Certified Manufacturer?
As a marigold lutein extract supplier and manufacturer, KH Health controls quality from petal harvest to finished powder. Free lutein is HPLC-verified on every lot, zeaxanthin is reported alongside, and each batch ships with a certificate of analysis covering heavy metals, pesticides, and microbiology. Powder and beadlet forms are produced in our FSSC 22000, Kosher, Halal, and SC certified facility in Xi'an, Shaanxi, China, giving eye-care brands a consistent, documentable raw material.
1. Free Lutein vs Lutein Esters Content Conversion Standard: There is a significant potency difference between free lutein and lutein esters, with an effective content gap of approximately 2 times. As the industry universal conversion benchmark, lutein esters are equivalent to half the effective dose of free lutein. All our product quotations are marked with a clear content benchmark to ensure buyers accurately calculate formula dosage and avoid content mismatch and procurement loss caused by inconsistent detection standards.
2. Customizable Lutein & Zeaxanthin Ratio for Eye Care Formulas: For eye health supplement formulations, the lutein-to-zeaxanthin ratio directly determines the eye protection efficacy. Our marigold lutein bulk powder supports customized proportional configuration, with the mainstream classic eye care ratio of 10:1 (Lutein : Zeaxanthin). We can adjust the proportion according to customers’ finished product formula requirements, and all product parameters and quotation sheets will clearly mark the ratio data to meet standardized eye care product production needs.
3. Strict Grade Separation: Feed Grade vs Supplement Grade: Our factory strictly distinguishes feed-grade lutein powder and dietary supplement-grade lutein powder in production standards, purification process, safety indicators and application scenarios. The two grades adopt different raw material purification processes, heavy metal control standards and microbial detection thresholds, and cannot be directly compared in price or substituted for each other. Supplement-grade products meet strict food-grade and human consumption standards, while feed-grade products are specially used for livestock and poultry coloring and breeding nutrition, ensuring customers select matched products according to end-use scenarios.
Manufacturing & Quality Control
Raw Material Traceability — Marigold petals are sourced from managed cultivation bases and screened for pesticides, heavy metals, and microbiology before processing.
Controlled Extraction & Purification — Solvent extraction followed by purification and saponification (where free lutein is required) proceeds under controlled, documented conditions.
Batch-by-Batch Testing — HPLC lutein and zeaxanthin assay, moisture, heavy metals, pesticides, and microbiology are verified on every lot.
Protected Packaging — Light-barrier, sealed packaging with cool, dry warehousing protects the carotenoid across the 24-month shelf life.
Where Lutein Goes To Work
1. Eye Health & Vision Support Supplements
Eye health is a long-established supplement category that continues to grow with aging populations, and lutein is the category's best-known active.
Lutein 20% powder doses precisely into capsules, tablets, and softgels, and stacks with zeaxanthin, bilberry extract, and vitamin A for complete vision blends.
2. Screen-Distance & Digital Lifestyle Products
Screen-time awareness is driving demand for daily eye-comfort supplements positioned around blue-light exposure among younger consumers.
Low-dose, once-daily gummies, sticks, and tablets combine lutein with zeaxanthin and antioxidants in convenient, consumer-friendly formats.
3. Food & Beverage Fortification
Food manufacturers are adding vision-support nutrients to everyday carriers, but carotenoid stability and color can complicate fortification.
Beadlet and cold-water-dispersible grades protect lutein in beverages, dairy, bakery, and nutrition bars with controlled color impact.
Food-grade compliance, stability guidance, and per-batch documentation support reproducible fortification in regulated food markets.
4. Beauty-from-Within & General Nutrition Blends
Oral beauty and daily multivitamin lines increasingly include carotenoids for skin and eye wellness in one combined daily dose.
Lutein powder blends cleanly into multivitamin tablets and beauty sticks alongside collagen, vitamin C, and astaxanthin without flavor impact.
