Description

Superpure Astaxanthin Powder

Superpure Astaxanthin Powder represents the pinnacle of natural antioxidant ingredients - a premium, high‑purity carotenoid pigment extracted from the microalga Haematococcus pluvialis using state-of-the-art Supercritical Fluid Extraction (SCFE) technology. This solvent‑free process ensures exceptional purity and potency, delivering a product that meets the stringent quality requirements of the most demanding global markets, including the US, EU, and Japan.

👑 The "Ultra-Pure King of Carotenoids": With a guaranteed purity of ≥95% by HPLC, superpure astaxanthin is widely recognized as one of nature's most powerful lipid‑soluble antioxidants. Its unique molecular structure enables it to span the entire cell membrane, providing comprehensive protection against oxidative stress both inside and outside the cell.

Superior Purity and Bioactivity: Unlike standard astaxanthin powders that may contain carriers or lower concentrations, our superpure grade offers the highest concentration of active astaxanthin available. Each batch is rigorously tested for purity (>95% by HPLC), heavy metals, and microbial contamination.

The Natural Source Advantage: Sourced from Haematococcus pluvialis microalgae, our astaxanthin provides a specific stereoisomer profile ((3S,3′S)) that is considered more bioavailable and superior in antioxidant activity than synthetic forms.

❄️ Storage Note: Superpure astaxanthin is highly sensitive to light, heat, and air. Store under inert gas (nitrogen or argon), protected from light, at -20°C for long‑term stability. Short‑term storage at 2–8°C is acceptable.

Benefits of Superpure Astaxanthin Powder

01Superior Antioxidant Defense

Astaxanthin's primary mechanism is its exceptional ability to neutralize singlet oxygen and scavenge free radicals. Protects cells, particularly mitochondria, from oxidative stress - without being consumed in the process.

02Supports Healthy Aging

By reducing oxidative stress and inflammation, astaxanthin supports cellular health and may promote healthy aging.

03Cardiovascular Support

Improves lipid profiles, promotes cholesterol efflux, and protects endothelial function - supporting heart health.

04Neuroprotection

Crosses the blood-brain barrier. Potent anti-inflammatory and antioxidant effects are being studied for neurodegenerative conditions.

05Skin Health & Photoprotection

Protects skin from UV‑induced damage, reducing signs of aging. Supports skin health by mitigating inflammation and oxidative stress.

FAQ

Q1: What is the difference between superpure astaxanthin and standard astaxanthin powder?

A: Superpure astaxanthin represents the highest purity grade available (≥95% – ≥99% by HPLC). It is typically crystalline or highly concentrated, with no carriers or fillers. Standard astaxanthin powders often contain lower concentrations (2.5% – 10%) and use carriers such as starch or maltodextrin. Superpure grade is ideal for research, pharmaceutical applications, and premium nutraceuticals requiring maximum potency.

Q2: Why is superpure astaxanthin so expensive?

A: The high cost reflects the advanced SCFE extraction technology, rigorous purification processes, and the high concentration of active astaxanthin. A small amount of superpure powder provides equivalent potency to a much larger amount of standard powder, making it cost‑effective for high‑potency formulations.

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. Using superpure astaxanthin requires careful dosing due to its high concentration. Always consult a healthcare provider.

Q4: Is superpure astaxanthin safe?

A: Astaxanthin has an excellent safety profile and has been demonstrated safe in numerous human clinical trials. Doses in clinical trials have ranged from 1 mg/day to 40 mg/day, with most in the 6‑12 mg range. Single‑dose pharmacokinetic studies have used up to 100 mg per dose.

Q5: How should I store superpure astaxanthin powder?

A: Store in the original sealed container, protected from light, under inert gas (nitrogen or argon), at -20°C for long‑term stability. Short‑term storage at 2–8°C is acceptable, but -20°C is recommended for maintaining potency over extended periods. It is sensitive to light, heat, and air.

Q6: Is superpure astaxanthin vegan?

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

Q7: What is the shelf life?

A: 3 years when stored at -20°C in powder form; 1 year at -80°C in solvent. Stability is enhanced by inert gas packaging and light‑protected foil bags.

Q8: Is superpure astaxanthin soluble in water?

A: No. Astaxanthin is insoluble in water. For water‑dispersible applications, use micro‑encapsulated (ME) powders or beadlets, which are formulated to disperse in cold water.

Q9: Can superpure astaxanthin be used in clear beverages?

A: No - the crystalline form is insoluble in water. For beverage applications, use micro‑encapsulated (ME) powders which are cold‑water dispersible.

Q10: What is the difference between superpure astaxanthin and astaxanthin oleoresin?

A: Superpure astaxanthin is the purified, crystalline form of astaxanthin (≥95% purity). Astaxanthin oleoresin is the crude extract from the algae, containing astaxanthin along with lipids and other compounds. Superpure grade is significantly more concentrated and pure.

Q11: Can superpure 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 superpure 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. Its high potency makes it ideal for premium sports nutrition formulations.
