Many bulk astaxanthin materials on the market come with unstable algae sources, incomplete wall breaking or mixed synthetic ingredients, resulting in uneven color and inconsistent active content across batches. Our natural astaxanthin powder undergoes strict raw material screening, low-temperature cell wall breaking and fine purification procedures. The finished powder presents uniform dark red or reddish-brown color, fine loose texture and pure microalgae scent. No artificial pigments, synthetic flavors or unnecessary fillers are added during production. With stable lipid-soluble activity and clean ingredient composition, it fits clean-label formula development, cosmetic compounding, functional food fortification and large-scale bulk export.

Product Specifications

We supply multiple standard grades of natural astaxanthin powder extracted from Haematococcus Pluvialis. Conventional specifications cover common UV and HPLC testing standards, with customizable active content and particle size to match dietary supplement, skincare and functional food production needs.

Our Supplier Advantages

We adopt standardized microalgae screening and low-temperature extraction production lines for natural astaxanthin. Strict source control and batch testing mechanisms ensure stable active content, clean impurity spectrum and consistent quality for bulk export orders.

• Strict Microalgae Source Control: Select high-quality cultivated Haematococcus Pluvialis with sufficient active accumulation, effectively avoiding inferior raw materials with low activity and impurity excess.

• Efficient Wall-Breaking & Low-Temp Extraction: Physical cell wall breaking technology improves active substance release rate, while low-temperature processing protects natural carotenoid activity from thermal damage.

• Multi-Stage Purification Treatment: Gradient impurity removal and fine filtration reduce residual impurities, ensuring pure powder texture and stable formula performance.

• Full Batch Inspection System: Each batch undergoes content detection, appearance inspection, heavy metal and microbial testing before shipment, with complete test reports provided.

• Customized Service Support: Support active concentration and particle size adjustment, private label packaging, and complete export documents including COA and MSDS.

Packaging & Storage Guidelines

• Standard Export Packaging: 1kg aluminum foil vacuum bag; 25kg food-grade fiber drum with inner plastic lining bag

• Storage Conditions: Store in cool, dry, dark and ventilated warehouse, avoid high temperature, humid environment and strong light exposure.

• Storage Reminder: Astaxanthin is sensitive to light and heat. Please keep tightly sealed after opening to prevent oxidation, color fading and active substance attenuation.

FAQ

Q1: What is the difference between natural and synthetic astaxanthin?

A1: Natural astaxanthin is extracted from Haematococcus Pluvialis microalgae, featuring natural ingredient structure, good compatibility and clean impurity profile. Synthetic astaxanthin is chemically synthesized, with relatively higher residual substances and limited application in high-end clean-label products.

Q2: Does your astaxanthin powder contain additives?

A2: Our bulk natural astaxanthin powder is pure microalgae extract without adding artificial pigments, flavors or inert fillers, retaining original natural ingredient properties for independent formula compounding.

Q3: What are MOQ and delivery time?

A3: Small sample orders are supported for quality verification and formula trial. Conventional specifications are in stock for fast delivery. Customized concentrations require separate production cycle confirmation.
