Astaxanthin Supplier

Organic astaxanthin Powder is the flagship product in carotenoid science, derived from premium Haematococcus pluvialis microalgae.This naturally occurring keto-carotenoid comprises the active (3S, 3’S) stereoisomer and has an antioxidant potential roughly 6,000 times greater than Vitamin C.Our haematococcus pluvialis powder is protected from harm due to oxidation, light and heat that can break down the fragile molecular framework by superior beadlet microencapsulation technology.A stable, concentrated, dark red powder, this is a high performance choice for formulators of nutritional supplements, functional foods and cosmeceuticals where high performance is required and is available in strengths of 2% to 5% test.

Third Test Report

Third Party Independent Verification for Quality Assurance: We cooperate with internationally recognized third party laboratories such as SGS and Eurofins to provide full product validation in addition to our own quality control methods.

Pesticide Residue Analysis: Multi-residue screening assures compliance with the EU and USDA organic standards providing the confidence that your formulations are made with heavy pesticide free materials to meet tight regulatory criteria.

Pure Astaxanthin Powder Advantages

Better Stereochemistry: Our natural extraction produces just the (3S, 3'S) isomer configuration, which is 20X more potent in antioxidant efficiency than synthetic, petrochemical-derived competitors with mixed isomer ratios.

Advanced Microencapsulation Technology: Our proprietary beadlet formulation prevents astaxanthin molecules from premature oxidation, providing a shelf life of 24-36 months with >95% potency retention when stored properly.

Cold Water Dispersible Options: For beverages, our proprietary CWD technology turns lipophilic astaxanthin into nanosphere emulsions that disperse uniformly without separation of oil or rings.

Pure Astaxanthin Powder Application

Dietary Supplements: Create softgels, hard capsules and tablets for clinical dosages from 4mg to 12mg per day targeting oxidative stress, ocular health, cardiovascular support and sports recovery markets.

Functional Foods & Beverages: Integrate into protein powders, meal replacement shakes, energy bars and fortified drinks, offering natural colour and functional antioxidant advantages for health-conscious consumers.

Cosmeceuticals & Skincare: Natural astaxanthin powder is used in topical formulations such as anti-aging serums, sun protection formulae, and skin brightening treatments where astaxanthin's membrane-spanning antioxidant action protects against photoaging and environmental stresses.

Production Process

Step 1 - Microalgae Cultivation: We grow premium strains of Haematococcus pluvialis in controlled photobioreactors, ensuring ideal light, temperature and nutritional conditions, leading to algal biomass with maximal astaxanthin accumulation greater than 5% dry weight.

Step 2 - Harvesting & Drying: Mature algae are separated through centrifugation and then spray dried at carefully controlled temperatures to maintain cellular integrity and reduce thermal destruction of sensitive carotenoids.

Step 3 - Supercritical CO2 Extraction: Dried biomass is loaded into supercritical fluid extraction chambers where CO2 under certain pressure and temperature selectively dissolves the astaxanthin lipids, yielding solvent-free oleoresin of extraordinary purity.

Step 4 - Microencapsulation: The concentrated oleoresin is spray-dried with protective matrices such as modified starch and gum arabic to form stable powder beadlets that preserve astaxanthin from oxygen, light and moisture.

Step 5 - Quality Testing & Packaging: Each batch is rigorously tested by HPLC assay, heavy metals, microbiological and pesticide screening to provide approved products for your formulation needs before being packaged with Nitrogen-flushing.

FAQ

Q: How is the natural product different from the synthetic?

A: Natural astaxanthin from Haematococcus pluvialis includes just the (3S, 3’S) isomer, which has demonstrated the strongest antioxidant activity. Synthetic forms are blends of petrochemicals with just 25% of the active form and are utilized mostly in animal feed, not in human nutrition.

Q: Why the specs are 2-5% and not pure astaxanthin?

A: Crystalline astaxanthin oxidizes fast when exposed to air. Shelf life is guaranteed for 24-36 months, microencapsulated in protective matrices. Percentage of active ingredient content by weight in the stabilized powder form.

Q: Can the product dissolve in water-based formulations?

A: The standard powder is lipophilic, however for beverage applications we have Cold Water Dispersible (CWD) technology using nano-emulsification so that it can be uniformly dispersed without oil separation.
