Why Choose Our Astaxanthin?
- Our Astaxanthin Base
Our production base benefits from ample sunlight, high-quality air, pure water sources, and suitable temperatures, providing an unparalleled natural environment for the development of Haematococcus pluvialis. With a 350,000 m² industrial base for Haematococcus pluvialis, the average annual astaxanthin content exceeds 6%. The algae cultivated in high-altitude, pristine waters are more natural, organic, and pollution-free. - Premium Water Source
The water used in our production comes from the Himalayas, over 8,000 meters above sea level—some of the purest and cleanest water from high-altitude snowy mountains. From the Himalayas to our factory, the water passes through the Jinsha River, the source of the Yangtze River, with no heavy industrial pollution along the way. Membrane filtration serves as the second “guarantee” to remove impurities and ensure water quality. Regular analysis is the third “guarantee” to ensure the water meets the growth conditions for algae, thereby guaranteeing the quality of the final product. - CO₂ Supercritical Fluid Extraction Technology
We utilize the most efficient, safe, and pure microalgae extraction technology. During the supercritical fluid extraction process, supercritical CO₂ is used as the solvent. After extraction, the liquid CO₂ evaporates naturally, ensuring the raw material is pure and free from chemical residues. - Enhanced Stability, Bioavailability, and Water Solubility
Through nano-processing, the effective components of microalgae achieve an average particle size of 50nm, increasing bioavailability by 6 times. After microencapsulation, stability is improved, and the product becomes water-soluble, significantly expanding its application scenarios.

A: There are three commercial sources of astaxanthin: Haematococcus pluvialis, synthetic, and microbial fermentation.
Q3: Which type of astaxanthin is approved as safe?
A: In fact, only astaxanthin extracted from Haematococcus pluvialis is approved and recognized as safe for human consumption.
Q4: What are the U.S. regulatory requirements for astaxanthin?
A: The FDA has approved natural algal astaxanthin from Haematococcus pluvialis as Generally Recognized As Safe (GRAS). The FDA-approved safe dosage is 12mg per day.
Q5: What are the EU regulatory requirements for astaxanthin?
A: The European Food Safety Authority has approved astaxanthin from Haematococcus pluvialis as a Novel Food ingredient. The panel concluded that a daily intake of 8mg of astaxanthin from food supplements is safe for adults.
Q6: What are China’s regulatory requirements for astaxanthin?
A: The China Food and Drug Administration has approved Haematococcus pluvialis as a Novel Food. The recommended daily intake of Haematococcus pluvialis is no more than 0.8g per day, equivalent to a maximum astaxanthin intake of 24mg per day.
Q7: How to choose a supplier of Haematococcus pluvialis-sourced astaxanthin?
A: There are several producers of Haematococcus pluvialis astaxanthin worldwide, each with different production methods. We believe a good algal astaxanthin producer should at least possess the following characteristics:
•Excellent pollution control. A closed PBR system is definitely better than an open raceway system exposed to the outdoors.
•Clean water sources are crucial.
•Cultivation under natural sunlight ensures true naturalness.
•No damage to the ecological environment.
