Lutein 5% HPLC (Marigold Extract)

Product Description

Lutein 5% (Marigold Extract) is a premium-grade natural carotenoid ingredient derived from high-quality marigold flowers (Tagetes erecta L.). As a crucial carotenoid constituent of the human macular region, lutein has become an essential industrial raw material for filtering blue light, reducing eye strain from digital screens, and preventing age-related macular degeneration (AMD) due to its potent antioxidant capacity.

Our Lutein 5% Powder is produced through a gentle solvent extraction and purification process, appearing as a vibrant orange-red fine powder. Tested strictly by High-Performance Liquid Chromatography (HPLC), the active lutein content is guaranteed to consistently reach ≥ 5.0%. The material features outstanding powder flowability and bulk density control (loose density 0.4–0.7 g/ml, tapped density 0.6–1.0 g/ml), allowing seamless integration into dietary supplements, eye nutrition capsules, functional tablets, and premix formulations to help brand owners develop market-competitive eye health products.

Key Features & Highlights

• High Standard Active Potency: Standardized by HPLC testing to guarantee an active lutein content ≥ 5.0%, delivering high batch-to-batch consistency and accurate active dosage for eye health formulations.

• Pure Marigold Origin: 100% extracted from premium marigold flowers, offering potent antioxidant activity and vibrant natural pigment attributes that meet consumer demand for clean-label, natural nutrition.

• Exceptional Processing Adaptability: 100% passes through an 80-mesh sieve with uniform particle distribution, excellent flowability, and dispersion, significantly reducing segregation risks during dry blending and enhancing production efficiency.

• High Safety & Low Residue Limits: Extraction solvents (hexane and ethanol) are maintained at minimal residual levels, with heavy metals (Pb, As, Cd, Hg) and pesticide residues strictly controlled within stringent international safety thresholds.

• Extended Shelf-Life Stability: Packaged in vacuum-sealed aluminum foil bags and stored away from light and heat, the product retains a long shelf life of 24 months, minimizing inventory loss risks for brand owners.

Formulator's Guide & Processing Advantages

• Uniform Pre-Mixing & Dispersion: The fine particle size (100% through 80 mesh) and optimal bulk density enable Lutein 5% Powder to achieve highly uniform dry blending with excipients like microcrystalline cellulose or starch, making it suitable for high-speed capsule filling and tableting processes.

• Light Sensitivity & Thermal Stability Management: Carotenoid structures are inherently sensitive to intense light, elevated temperatures, and oxygen. It is recommended to control processing temperatures and utilize light-barrier packaging or formulate in combination with antioxidants such as Vitamin C or Vitamin E to enhance end-product stability.

• Water Dispersion & Emulsification Recommendations: For softgel or oil-based systems, oil-soluble suspensions are recommended. For hard capsules or powder mixes, this product exhibits good powder compatibility and can be directly blended into standard formulation matrices.

Applications

• Targeted Eye Health Supplements: Specifically designed for anti-blue light capsules, eye strain relief tablets for gamers and office workers, and macular protection formulas for seniors, providing precise daily requirements of natural lutein.

• Golden Eye Protection Tri-Formula: Ideal for co-formulating with Zeaxanthin, Meso-Zeaxanthin, Astaxanthin, Bilberry Extract, and natural Zinc/Selenium to create differentiated products offering full-spectrum retinal protection.

• Functional Foods & Solid Beverages: Suitable for meal replacement powders, dry-blended energy bars, chewable tablets, and protein powder formulas, providing eye health benefits along with a natural orange-red hue and clean-label appeal.

• Pet Vision & Coat Health Care: Widely applied in premium pet eye care tablets, multi-vitamin pastes, and advanced canine/feline dietary supplements to support cataract prevention and ocular antioxidant capacity.

• Oral Beauty & Photo-Aging Defense: Utilizes powerful carotenoid free-radical scavenging properties, combining with collagen and European bilberry for oral anti-aging, UV defense, and skin photoprotection products.
  
  

Quality Assurance & Global Compliance

• Rigorous Microbiological & Pesticide Control: Every batch undergoes strict testing under CP2010 microbiological standards, guaranteeing zero pathogenic bacteria (E. coli, Salmonella) and organochlorine pesticide residues far below international limits.

• Heavy Metal Compliance: Tested via Atomic Absorption Spectrometry (AAS) to strictly monitor Lead, Arsenic, Cadmium, and Mercury, complying fully with North American and European import regulations for botanical extracts.

• Standardized Packaging: Inner layer uses vacuum-sealed aluminum foil bags (1kg or 5kg) and outer layer utilizes 25kg standard fiber drums, effectively blocking oxygen and moisture to ensure quality stability during long-distance ocean shipping.

FAQ

Q1: What is the solubility of Lutein 5% Powder? Can it be directly used in clear beverage formulas?

A1: Lutein 5% Powder is a dry powder form of natural oil-soluble carotenoids processed for solid application. It forms a suspension in water. For clear liquid beverages, we recommend choosing water-soluble (WS) or microencapsulated grades of Lutein.

Q2: How can I ensure the potency stability of Lutein during manufacturing and storage?

A2: Lutein is sensitive to heat, light, and oxygen. We ship our products in vacuum-sealed aluminum foil packaging. Factories should store the material in cool, dry, and dark environments and use light-barrier packaging for finished products.

Q3: Why choose an 80-mesh particle size? What are the processing benefits for tableting or capsule filling?

A3: An 80-mesh particle size (100% pass rate) represents an optimal balance for solid oral dosage manufacturing. It ensures uniform dry mixing with excipients like MCC or starch while avoiding issues like machine sticking or weight variation caused by excessively fine dust.

Q4: Does your Lutein raw material comply with pesticide and heavy metal regulations in Europe and North America?

A4: Yes, completely. Every batch is rigorously tested for organochlorine pesticides (e.g., 666, DDT, Quintozine) and heavy metals (Pb, As, Cd, Hg), staying well below the strict thresholds set by USP and European Pharmacopoeia (EP).

Q5: What is the recommended formulation ratio of Lutein 5% to Zeaxanthin for eye health products?

A5: Based on clinical research (such as the AREDS2 study), the natural ratio found in the macular region is 5:1 (Lutein to Zeaxanthin). You can easily combine our Lutein 5% with Zeaxanthin ingredients according to this golden ratio.

Q6: Can you provide samples for HPLC assay testing? What is your Minimum Order Quantity (MOQ)?

A6: Yes, Keep Ingredients provides free 50g–100g samples for HPLC potency testing and stability evaluation. We support flexible low-MOQ purchasing to help reduce financial risks for new R&D projects.
