The difference is in our total control of the whole production chain from our own Haematococcus pluvialis growing bases, to the most advanced supercritical CO2 extraction technology and microencapsulation procedures. Through this vertical integration we overcome three important difficulties in the industry, oxidative instability, poor water dispersibility and variable bioavailability. Shaanxi Hongda will provide you with a stabilized powder formulation which may be easily incorporated into capsules, tablets, functional beverages and cosmetic applications and has a 24-36 month shelf life when properly stored.

Astaxanthin Powder Supplier

Organic astaxanthin bulk powder is the zenith of carotenoid technology, sourced from the microalgae Haematococcus pluvialis, via advanced extraction and microencapsulation processes. This dark red powder provides the antioxidant activity of astaxanthin in a stable, easy-to-handle shape that avoids the constraints of raw oleoresin. Our formulation turns the lipophilic molecule into a water dispersible or tablet compressible matrix that is suitable for a broad spectrum of industrial situations. The powder form means accurate constant dosing, removes the possibility of cross-contamination and retains efficacy over the life of your product. Whether you are formulating dietary supplements, beauty-from-within beverages or anti-aging skin care, our powder offers the functional stability and bioavailability your formulations require.

Third-Party Test Report

Testing Authority: We work with world-class labs like SGS and Eurofins to ensure complete transparency and compliance with international standards.

Pesticide Residue Analysis: All lots are extensively tested for more than 500 pesticide chemicals with GC-MS/MS and LC-MS/MS techniques and consistently show non-detectable levels below EU legal limits.

Heavy Metal Testing: We test our products for Lead, Arsenic, Cadmium and Mercury. Our products are regularly tested at or below the levels set by the FDA and EU for dietary supplements and food ingredients.

Microbiological Safety: Each batch is tested for total plate count, yeast and mould, E.coli and Salmonella to assure consumer safety and regulatory compliance in all target markets.

Product specification

Synthetic Astaxanthin VS Natural Astaxanthin

Synthetic astaxanthin is an industrially produced antioxidant with low cost but weak biological activity and is mainly used in aquaculture and feed industries. Natural astaxanthin has stronger antioxidant capacity and is more suitable for high-end health products and cosmetics.

Astaxanthin Powder Advantages

Improved Stability Profile: Our microencapsulation method protects the active compound from oxidative degradation, light exposure and temperature changes, helping your final goods maintain potency throughout their shelf life.

greater bioavailability: Haematococcus pluvialis bulk powder matrix is more readily absorbed in the digestive tract than raw oleoresin, ensuring the customer receives the entire antioxidant effect with greater efficacy.

Manufacturing Flexibility: Our powder blends are available in both standard and Cold Water Dispersible formats and easily integrate into dry blending processes, direct compression tableting, encapsulation lines and beverage production without requiring equipment adjustments.

Traceable Natural Origin: Fully traceable to our controlled algae cultivation bases, with complete documentation to prove it is 100% natural in origin, an important distinction from synthetic petroleum-derived competitors with inferior stereoisomer profiles.

Astaxanthin Powder Application

Nutraceutical Supplements: Haematococcus pluvialis powder is the base for formulations aimed at cardiovascular health, eye health supplements, and sports recovery products, usually dosed at 4-12mg active astaxanthin per serving in capsule or tablet form.

Functional Beverages: Manufacturers use the powder in beauty drinks, protein shakes and wellness drinks with Cold Water Dispersible technology that can withstand pasteurization and disperse evenly without separating.

Cosmeceutical Products: Haematococcus pluvialis astaxanthin powder has a UV protection property and inhibits melanin formation that makes it suitable for inclusion by premium skincare companies in facial masks, serums and topical creams for anti-aging and whitening the skin.

Sports Nutrition: Fitness brands use the substance into pre-workout formulae and recovery blends, where its ability to reduce muscle fatigue and mitigate exercise-induced oxidative stress offers actual performance benefits.

Production Process

Step 1 - Algae Cultivation: We grow Haematococcus pluvialis in regulated photobioreactors under optimum stress settings that induce maximal astaxanthin accumulation in the algal cells, producing high-quality raw material with superior carotenoid concentration.

Step 2 – Harvesting & Drying: The algal biomass is harvested at the pinnacle of maturity and is subjected to a regulated low temperature drying process. This protects the integrity of the carotenoid structure while lowering the moisture content of the algae for efficient extraction.

Step 3 – Supercritical CO2 Extraction: We extract the oleoresin using pharmaceutical grade supercritical fluid extraction under tightly regulated pressure and temperature conditions without the use of chemical solvents, providing a clean extract free of residues.

Step 4 – Microencapsulation: The oleoresin is embedded into a protective matrix using spray-drying or fluidized-bed coating technology, creating stable microbeads that shield the active compound from environmental stressors.

Step 5 – Quality Testing & Packaging: Each production batch undergoes rigorous testing in our SGS-standard laboratory, before being packaged in double-layer PE bags within fibre drums in a nitrogen atmosphere, assuring product integrity during shipping and storage.

FAQ

Q: What is the difference between the natural and synthetic form of your product?

A: Our product is only generated from Haematococcus pluvialis and has the (3S, 3'S) stereoisomer with higher biological activity. Synthetic alternatives are racemic mixes generated from petrochemicals containing only 25% of the effective isomer and are therefore far less potent for human nutrition purposes.

Q: Why is the concentration usually 2-5% and not higher?

A: Pure crystalline astaxanthin is oxidized very rapidly by contact with air. Our microencapsulation method encapsulates the active chemical in a protective matrix, which guarantees a shelf life of 24-36 months. Food-grade and GRAS-certified carrier materials provide stability and safety.

Q: Can your powder disperse in cold water for beverage application?

A: Yes, our Cold Water Dispersible (CWD) formulation employs sophisticated emulsification technology to provide homogeneous dispersion in aqueous systems, without oil rings or settling and stable through ordinary beverage processing conditions.

Q: What paperwork do you give to meet regulatory requirements?

A: We provide full paperwork to back your registrations internationally including Certificates of Analysis, allergen statements, GMO-free declarations, BSE/TSE certificates, pesticide residue reports, heavy metal testing results and shelf-life stability data.

Q: How much of the supplement should be taken daily in a formulation?

A: Clinical studies indicate that 4-12mg of active astaxanthin daily is effective. That’s 200-600mg of powder per serving, when compounding with our 2% powder. Suggestions are given for dose based on your intended use and the market requirements.
