Our powder is produced from marigold, meets AREDS2 formulation requirements, has a regulated particle size distribution for easier capsule filling and has a 24 month shelf life when stored appropriately. Competitive pricing with direct manufacturer supply without intermediaries. ISO, FDA and Kosher compliance.

What Makes Our Zeaxanthin Powder Different?

It is a xanthophyll kind of carotenoid and is obtained mostly from the petals of the marigold plant, Tagetes erecta L. It is an important macular pigment that filters damaging blue light wavelengths of 400-500nm.

Bioavailability problems of raw carotenoids in the nutraceutical sector. Our proprietary microencapsulation method produces protective beadlets that are resistant to changes in gastric pH and that improve absorption rates in the intestine. The powder is composed of orange-yellow tiny particles which have good flow qualities of importance for automated encapsulation lines of high speed.

Our solution is highly appreciated by manufacturers as it addresses three technical challenges: avoiding photo-oxidation during transit, maintaining accurate Lutein-Zeaxanthin ratios (usually 5:1 in AREDS2 formulations), and ensuring uniform content distribution in manufacturing batches.

Technical Specifications

Primary Application Scenarios

Your formulation requirements determine the ideal application for our powder. In ophthalmic dietary supplements, you'll find it paired with lutein in softgels and tablets targeting macular density support. The micro-encapsulated structure withstands compression forces during tableting without beadlet rupture or oil bleeding.

For functional beverage manufacturers, cold-water-soluble variants disperse instantly in acidic vitamin drinks. No oily residue forms on liquid surfaces. This ensures uniform color distribution and consistent nutrient delivery in ready-to-drink formats.

Nutricosmetic brands incorporate the powder into ingestible beauty products. The antioxidant properties protect skin against UV radiation and blue light oxidative stress. Formulators appreciate the stability that maintains potency alongside Vitamin C and other sensitive actives throughout product shelf life.

Health Benefits and Functional Properties

Your customers consume Zeaxanthin Powder to protect retinal photoreceptor cells from oxidative damage. The compound accumulates in the macula lutea, creating a natural filter against high-energy visible light.

Clinical studies link adequate zeaxanthin intake with reduced age-related macular degeneration risk. The antioxidant neutralizes singlet oxygen species generated during phototransduction processes. This mechanism explains its effectiveness in relieving eye fatigue for screen users.

Beyond vision support, the ingredient demonstrates free radical scavenging capacity. Formulators combine it with omega-3 fatty acids and bilberry extract to create comprehensive eye health stacks. The synergistic effect enhances bioavailability compared to isolated carotenoid supplementation.

Manufacturing Excellence and Quality Assurance

With 14+ years of botanical extraction experience, we can ensure consistency from batch to batch. The chosen marigold petals are treated on six multifunctional production lines with the supercritical CO2 extraction systems. The closed-loop system minimises exposure to oxidation during concentration steps.

Each batch is tested for content by HPLC, screened for heavy metals by ICP-MS, and enumerated for microbes according to USP criteria. You will receive full COA paperwork with each shipment. Third party testing reports available upon request.

The plant is GMP-certified and audited once a year. Cleanroom conditions are used to control particle contamination in the final milling and packing steps. We operate HACCP procedures at all essential control points, from receipt of raw materials to release of final product.

Customization and OEM/ODM Services

We can extend our usual 20% content with bespoke parameters. Our R&D team will develop ratios based on study methodologies or regulatory requirements in your target markets. Private labelling includes consulting on package design and preparing compliance papers.

We also have custom spray-dried cold water dispersible variants for beverage applications. Flow agents mixed with direct-compression grades assist the tablet maker. We can also mill to customer specifications for new delivery methods with unique particle size distributions.

Standard specs have minimum order quantities of 25kg For bulk contracts above 500kg per annum, preferred pricing tiers are available. We have 30+ days safety stock to accommodate your production plans without supply interruptions.

Packaging, Storage and Global Delivery

Standard packaging is in 25 kg fibre drums lined with double layer food grade polyethylene bags. The sealed system prevents moisture and light from entering during shipping. For lower test batches we provide 1kg and 5kg aluminium foil packs.

Keep containers in a cool place away from direct sunlight below 25 °C. Shelf life is extended by refrigeration to beyond the 24 month label. After opening, reseal the vials right away and use within 90 days for maximum potency.

We send by sea for large order and by air express for urgent samples. In the summer months, our logistics partners ship to tropical areas in temperature-controlled containers. EXW, FOB, CIF and DDP delivery terms are available according to your Incoterms request. Our supply chain efficiency is shown in 98% on time delivery.

FAQ

Q: What makes your product different from the competition?

A: Our product is confirmed at 20% HPLC and is fully traceable by batch. The microencapsulation method prevented the oxidative deterioration during shelf life. You get direct factory pricing without distributor mark-ups, but still with pharmaceutical grade quality standards.

Q: Can you provide paperwork for regulatory submissions?

A: Yes. We can supply COA, MSDS, TDS, allergies statements, non-GMO declarations. We develop technical dossiers in support of Novel Food applications for EU markets. For special customer needs, Kosher and Halal certificates can be provided.

Q: How do you maintain consistent quality between production batches?

A: Xanthophyll content is screened in marigold flowers before processing. In-process controls are performed to check the yields and purity of the extract at each step. The warehouse release of final products is subject to the QC Manager permission after passing all tests of specification.

Q: What is the normal lead time for custom formulas?

A: We send standard orders within 15 business days of receiving payment confirmation. Custom specs: 7-10 days for sample development, then 20-25 days for production runs after formula clearance. Rush orders can be accommodated based on our current production schedule.
