Description

Pure Natural Astaxanthin Powder

Pure Natural Astaxanthin Powder is a premium, high-purity carotenoid pigment extracted from the microalga Haematococcus pluvialis, widely recognized as the richest natural source of this potent antioxidant. This microalgae is cultivated in controlled environments, and under stress conditions (bright light, high salinity, nutrient deprivation), it produces and accumulates astaxanthin as a protective mechanism, reaching up to 4% of its dry weight.

👑 The "King of Carotenoids" from Nature: Our natural astaxanthin is derived from Haematococcus pluvialis through gentle extraction processes, including solvent-free supercritical CO₂ extraction, ensuring a high-purity product with no residual solvents. This natural source provides a specific stereoisomer profile ((3S,3′S)) that is considered more bioavailable and superior in antioxidant activity than synthetic forms.

Superior Antioxidant Power: Astaxanthin is one of nature's most powerful lipid-soluble antioxidants. Its ability to quench singlet oxygen and scavenge free radicals is significantly higher than that of other carotenoids. Its unique molecular structure enables it to span the entire cell membrane, providing comprehensive protection against oxidative stress both inside and outside the cell.

Pure and Potent: Our natural astaxanthin powder is available in various strengths (2.5%, 5%, 10%) to suit diverse applications. Each batch is rigorously tested for assay, heavy metals, and microbial contamination.

🌞 Storage Note: Astaxanthin is sensitive to light, heat, and oxygen. Store in the original sealed container, protected from light, under cool, dry conditions (≤25°C, ≤60% RH). Microencapsulated formulations offer enhanced stability.
