Description

Astaxanthin Powder

If antioxidants had a royal court, astaxanthin would be the undisputed monarch. This deep red pigment, derived primarily from the microalgae Haematococcus pluvialis, is widely regarded as one of nature's most powerful lipid-soluble antioxidants. It is the compound responsible for the pink hue of salmon, shrimp, and flamingos, but its function in the human body is far more profound.

👑 The "King of Carotenoids": Astaxanthin's unique polar-nonpolar-polar configuration allows it to span the lipid bilayer of cell membranes, providing comprehensive protection against oxidative stress both inside and outside the cell. Unlike conventional antioxidants that sacrifice themselves in the process, astaxanthin's extended conjugated double-bond system efficiently quenches free radicals and stabilizes them without being destroyed.

Superior Antioxidant Power: Research indicates that astaxanthin's antioxidant activity significantly surpasses that of many other antioxidants. It has been reported to be up to 100 times more effective than α-tocopherol (vitamin E) and significantly more potent than beta-carotene and lycopene in quenching singlet oxygen.

Sourcing and Stability: The primary commercial source of natural astaxanthin is Haematococcus pluvialis. Our astaxanthin powder is extracted using advanced Supercritical Fluid Extraction (SCFE) technology, a solvent-free process that ensures the highest purity and potency. We offer it in various stabilized forms, including micro-encapsulated powders (ME) and beadlets.

FAQ

Q1: What is the difference between natural and synthetic astaxanthin?

A: Natural astaxanthin, derived from Haematococcus pluvialis, is a mixture of specific stereoisomers ((3S,3′S)) and is considered more bioavailable and superior in antioxidant activity than the synthetic form. Our product is derived from this premium natural source.

Q2: Why is astaxanthin considered the "king" of antioxidants?

A: Unlike many antioxidants that sacrifice themselves when neutralizing a free radical, astaxanthin's unique molecular structure allows it to stabilize free radicals without being consumed. It is also one of the few antioxidants that can span the entire cell membrane, providing protection to both the inside and outside of the cell.

Q3: What is the recommended dosage?

A: For general wellness and antioxidant support, 2–6 mg per day is common. For specific applications like sports performance or metabolic support, doses of 6–12 mg per day are often used. Always consult a healthcare provider.

Q4: Is astaxanthin safe?

A: Astaxanthin has an excellent safety profile. It is a natural dietary pigment with a long history of human consumption through seafood. No significant side effects have been reported at recommended dosages.

Q5: Why is your product offered in different strengths (2.5%, 5%, etc.)?

A: Pure astaxanthin is highly potent and used at very low concentrations. The powdered carrier systems (ME, beadlets) allow for easy handling and accurate dosing in your formulations. Higher-strength powders (e.g., 10%) are more potent, while lower strengths (e.g., 2.5%) may offer better stability and coloring properties.

Q6: How should I store astaxanthin powder?

A: Store in a cool, dry place, protected from light and air. For long-term stability (e.g., bulk raw material), we recommend storing at -20°C. Our light-protected foil packaging helps maintain potency. Once opened, use promptly and reseal tightly.

Q7: Does astaxanthin have a taste or odor?

A: Pure astaxanthin has a characteristic algal note. Our micro-encapsulated powders use food-grade encapsulants that help to mask this flavor, making it suitable for a wide range of food and beverage applications.

Q8: Is astaxanthin vegan?

A: Yes. Our astaxanthin is derived from microalgae (Haematococcus pluvialis), a sustainable, vegan source, unlike astaxanthin from krill or other marine sources.

Q9: Can astaxanthin be used in clear beverages?

A: Yes - our micro-encapsulated (ME) powders provide excellent cold-water dispersibility, making them suitable for a wide range of beverage applications, including clear and lightly colored drinks.

Q10: What is the shelf life of astaxanthin powder?

A: 24 months when stored under recommended conditions (cool, dry, light-protected). Micro-encapsulated formulations offer significantly enhanced stability compared to non-encapsulated forms.

Q11: Can astaxanthin be combined with other antioxidants?

A: Yes - astaxanthin works synergistically with Vitamin E, Vitamin C, CoQ10, and other carotenoids. We offer custom blends and combination formulations.

Q12: Is astaxanthin suitable for sports nutrition products?

A: Yes - astaxanthin is widely used in sports nutrition for its ability to reduce exercise-induced muscle damage, enhance endurance, and support faster recovery. It is a popular ingredient in pre- and post-workout formulas.
