1 Active ingredient
Natural astaxanthin: a potent ketocarotenoid with a chemical formula of C40H52O4, a molecular weight of 596.86, and a CAS number of 472-61-7. Its structure contains two hydroxyl groups and a ketone group, giving it a super antioxidant capacity (the ability to scavenge free radicals is 550 times that of vitamin E and 10 times that of β-carotene).
2 Sources:
Haematococcus pluvialis: the main natural source, which can accumulate astaxanthin to 1%-5% of the cell dry weight through photobioreactor or open pond cultivation.
Other sources: Antarctic krill, yeast (Xanthophyllomyces dendrorhous), etc.

1. Antioxidant and anti-aging
• Scavenging free radicals: inhibit lipid peroxidation (such as inhibiting malondialdehyde production) through the singlet oxygen quenching mechanism, and protect cell membrane and mitochondrial function.
• Anti-photoaging: reduce UV-induced DNA damage and collagen degradation, and increase SPF value in some skin care products.
2. Neuroprotection and brain health
• Improve cognitive function: In the D-galactose-induced aging model, astaxanthin increased superoxide dismutase (SOD) activity by 30%, glutathione peroxidase (GSH-Px) activity by 53%, and repaired mitochondrial respiratory chain function.
• Anti-neurodegenerative disease: inhibit β-amyloid aggregation and alleviate neuronal damage in Alzheimer's and Parkinson's disease models.
3. Metabolism and cardiovascular health
• Lowering blood pressure: reduce systolic blood pressure in spontaneously hypertensive rats by regulating α-adrenergic receptors and angiotensin II pathways.
• Regulate blood lipids: reduce the risk of low-density lipoprotein (LDL) oxidation and increase high-density lipoprotein (HDL) levels.
4. Anti-inflammatory and immune regulation
• Inhibit NF-κB pathway: reduce the release of pro-inflammatory factors such as TNF-α and IL-6, and relieve arthritis and chronic inflammation.
• Enhance immunity: activate macrophages and T cells, and improve the efficiency of antibody production.
5. Other applications
• Anti-cancer: induce HeLa cell apoptosis and inhibit tumor angiogenesis.
• Liver protection: reduce oxidative stress markers (such as protein carbonyl content) in alcoholic liver damage
1. Health products and medicines
• Antioxidant supplements: 4-12 mg daily dose for anti-aging and chronic disease management.
• Neuroprotective drugs: Compound preparations are used for adjuvant treatment of Alzheimer's disease.
2. Functional foods and beverages
• Sports supplements: Added to energy bars or drinks to relieve oxidative stress and improve endurance recovery.
• Natural preservatives: Inhibit Escherichia coli and Staphylococcus aureus in food.
3. Cosmetics and daily chemicals
• Anti-aging skin care products: 0.5%-2% concentration cream improves photoaging and synergizes with sunscreen ingredients to extend the SPF effect.
4. Aquaculture and feed
• Color enhancement and health regulation: Added to salmon feed to improve meat color and increase survival rate.
