Astaxanthin powder from haematococcus pluvialis extract
product description
Astaxanthin is a xanthophyll carotenoid naturally produced by the microalga Haematococcus pluvialis as a protective response to environmental stress. It is widely recognized as one of the most potent natural antioxidants, with in vitro singlet-oxygen quenching studies reporting potency up to 6,000 times that of vitamin C on a per-molecule basis. KH Health supplies astaxanthin as a B2B raw material for dietary supplements, functional foods, cosmetics and sports nutrition.
We offer natural, microalgae-derived astaxanthin in two formats. Beadlets standardized to 2%, 5% or 10% deliver excellent stability, flow and blending performance for tablets, capsules and powder mixes. Astaxanthin oil (5% or 10%) is designed for softgels, liquids and beauty formats where a lipid carrier is preferred. A synthetic astaxanthin grade is also available for cost-sensitive lines, with full specifications and documentation for either source.
As a vertically integrated manufacturer and exporter in Xi'an, China, we combine competitive bulk pricing, batch-consistent quality, complete documentation and responsive technical support. Whether you need R&D samples or container volumes for national distribution, our team is ready to support your formulation and supply chain.

FAQ
Q:What is the difference between natural and synthetic astaxanthin?
A:Natural astaxanthin is extracted from Haematococcus pluvialis microalgae and contains the same mix of stereoisomers found in nature, which many formulators prefer for clean-label positioning. Synthetic astaxanthin is produced by chemical synthesis and is typically lower in cost. We supply both options — natural beadlets and oil for premium lines, and synthetic grades where cost sensitivity matters — with full documentation for either choice.
Q:Which format should I choose — beadlets or oil?
A:Beadlets (2%, 5% or 10%) provide excellent stability, flow and easy blending, making them ideal for tablets, capsules and powder mixes. Astaxanthin oil (5% or 10%) suits softgel, liquid and beauty-format products where a lipid carrier is preferred. Our team can help you select the right format, particle size and strength for your filling lines and target positioning.
Q:Is astaxanthin suitable for vegan and allergen-free products?
A:Yes. Natural astaxanthin is derived from microalgae, not from animals, and is suitable for vegan formulations. Our beadlet and oil lines are produced under allergen-controlled processes, and non-GMO declarations plus allergen statements are available on request.
Q:What documentation do you provide with each batch?
A:Every batch ships with a full certificate of analysis covering identity, HPLC assay, heavy metals, residual solvents and microbiology, plus MSDS, allergen statement and export documentation. Third-party testing via SGS, Eurofins or your nominated laboratory can be arranged, and retention samples are kept for traceability.
