Haematococcus pluvialis is a freshwater species of unicellular Chlorophyta microalgae, celebrated globally as the premier and most abundant biological source of Natural Astaxanthin (a powerful ketocarotenoid).
Unlike synthetic astaxanthin synthesized from petrochemical derivatives, natural astaxanthin derived from *Haematococcus pluvialis* exhibits an exceptionally high antioxidant capacity. Under environmental stressors such as high salinity, nitrogen deficiency, elevated temperatures, and intense light radiation, these microalgae initiate a self-defense mechanism known as encystment, rapidly accumulating astaxanthin within their cellular compartments to protect their DNA and cellular structures from oxidative degradation.
For B2B buyers and formulation scientists, this natural source provides unmatched biological activity. The stereoisomerism of natural astaxanthin from *Haematococcus pluvialis* is strictly 3S, 3'S, which exhibits significantly higher bioavailability and free-radical scavenging capabilities compared to synthetic forms (3R, 3'S or 3R, 3'R mixtures). It acts as a powerful singlet oxygen quencher, offering skin elasticity support, cardiovascular health protection, anti-inflammatory mechanisms, and cognitive longevity benefits.
Rising consumer awareness regarding preventive healthcare has driven demand for natural astaxanthin softgels, tablets, and hard capsules. Enterprise buyers focus on stability, clean-label sourcing, and high concentration assays (typically 5% to 10% active content).
Astaxanthin is widely used as a premium anti-aging active. Formulators require micro-encapsulated water-soluble powders or cosmetic-grade oleoresins. These formats are integrated into serums, creams, and sunscreens to neutralize reactive oxygen species (ROS) and prevent UV-induced collagen degradation.
High-grade microalgae powder is utilized as a natural colorant and nutritional booster in functional beverages and premium animal feed. In aquaculture, natural astaxanthin is essential for the healthy coloration and immune system support of salmon, trout, and shrimp.
At Shaanxi Bieyouth Biotech Co., Ltd., we combine state-of-the-art closed Glass Photobioreactors (PBR) with advanced harvesting and extraction technologies to guarantee maximum yield, purity, and bio-activity.
Microalgae are first cultivated in a controlled green vegetative phase to maximize cell division and biomass growth. The culture is then transferred to the red induction phase, utilizing high light stress and nitrogen starvation to induce the accumulation of natural astaxanthin.
Due to the extremely resilient cell walls of *Haematococcus pluvialis* cysts, bioavailability is limited without proper milling. We utilize low-temperature mechanical bead milling and physical disruption processes to crack the cell walls at rates exceeding 95%, ensuring maximum nutrient release without heat degradation.
We avoid chemical solvent residues by using eco-friendly Supercritical Fluid Extraction (SFE) with CO2. This low-temperature, high-pressure process yields a pure, solvent-free astaxanthin oleoresin, which is subsequently converted into stable, standardized powders via advanced micro-encapsulation techniques.

Shaanxi Bieyouth Biotech Co., Ltd. provides comprehensive end-to-end OEM and ODM capabilities to deliver market-ready, customized astaxanthin and plant extract products.
We initiate detailed technical discussions to define specifications, compound percentages (e.g., 5% Astaxanthin), regulatory requirements, target delivery format, and volume expectations.
For OEM, we process according to your exact formulation. For ODM, our specialized Biological Research Institute engineers customized formulas, stable powder micro-encapsulations, or custom-packaged blends.
We produce laboratory-scale prototype batches for client assessment. These undergo HPLC analysis, stability studies, and microbiological screening before shipment for your confirmation.
Once samples are validated, bulk manufacturing begins in our GMP-compliant, double-workshop facility. Production parameters are closely monitored through our 5-tier quality control protocol.
Finished goods are double-bagged or customized in private-label drums/pouches. We manage customs documentation, certificate verification (COA, MSDS, FDA), and safe transit to major global regions.
Established in 2018, we bring years of experience in global trade, export logistics, and strict regulatory alignments to ensure smooth customs clearances.
Our microalgae processing and extract production workshops adhere strictly to GMP guidelines, guaranteeing batches with zero heavy metal or microbial contamination.
We specialize in manufacturing clean, healthy, and natural extracts, providing customizable solutions designed to maintain maximum biological efficacy.
Operating as a direct source factory allows us to offer competitive pricing structures, flexible order minimums, and rapid turnaround times.
Our logistics and regulatory compliance frameworks enable reliable export operations to markets including the US, UK, Canada, Russia, Australia, and beyond.
We formulate tailored plant and animal extracts to meet the specific purity, color, solubility, and bioactivity needs of cosmetics and pharmaceutical manufacturers.
We develop high-stability, food-grade additives that improve nutritional value, stability, and sensory profiles, conforming with global food safety standards.
Our cosmetic ingredients are designed for high stability, skin compatibility, and proven efficacy, supporting clean beauty formulations.
We meticulously select our raw materials and control our extraction processes, constantly refining our technologies to deliver high-quality functional ingredients.

Understanding the structural and chemical differences between natural microalgae-derived astaxanthin and petrochemical-derived synthetic astaxanthin is critical for product formulation and compliance.
| Property | Natural (*Haematococcus Pluvialis*) | Synthetic (Petrochemical Synthesis) | |
|---|---|---|---|
| Molecular Isomers | Essentially 100% 3S, 3'S (Highly bioavailable isomer) | Mix of 3R, 3'S, 3R, 3'R, and 3S, 3'S isomers | Mainly free form (unenesterified), highly prone to rapid oxidation |
| Esterification | Over 90% esterified (mono-esters and di-esters) for superior stability | Mainly free form (unesterified), highly prone to rapid oxidation | |
| Antioxidant Capacity | Up to 50-90 times higher singlet oxygen quenching than synthetic | Relatively weak; lacks complex bio-matrix co-factors | |
| Regulatory & Labels | Clean-label, organic-eligible, GRAS, US FDA certified | Strictly regulated; prohibited in dietary supplements in multiple countries | |
| Eco-Footprint | Carbon-capturing microalgae cultivation | Petrochemical synthesis routes involving high emissions |
We supply cosmetic, food, and feed-grade *Haematococcus pluvialis* powder. The standard concentrations of active Natural Astaxanthin are 1.5%, 2%, 3%, and 5% (measured by HPLC/UV-Vis). Custom oil formulations (astaxanthin oleoresin at 5% and 10%) are also available.
Natural astaxanthin is highly sensitive to heat, light, and oxygen. To ensure stability, we employ micro-encapsulation technology that coats the astaxanthin molecules within a protective starch or gelatin matrix. This process significantly improves stability, prolongs shelf life, and ensures consistent potency.
MOQs depend on the packaging format and formulation complexity. For standard bulk raw material powder, the MOQ typically starts at 1kg to 10kg. For customized private label OEM products, the lead time is generally 15-25 business days, including analytical testing and quality verification.
Yes, every product batch is dispatched with a Certificate of Analysis (COA) detailing HPLC assay values, moisture levels, microbial thresholds, and heavy metal concentrations (lead, arsenic, mercury, cadmium). We also supply Material Safety Data Sheets (MSDS) and technical documentation upon request.
Yes, our *Haematococcus pluvialis* cultivation relies entirely on clean mineral nutrients in closed bioreactors, free from synthetic pesticides or animal-derived ingredients. We offer vegan-compliant powder options suitable for clean-label supplements and natural cosmetics.
