Astaxanthin is a naturally occurring ketocarotenoid belonging to the xanthophyll family. It is widely recognized as one of the most potent antioxidants in nature, with an oxygen radical absorbance capacity (ORAC) that is:
| 出典 | 収量 | 特徴 |
|---|---|---|
| Haematococcus pluvialis (microalgae) | 1.5–3% dry weight | Highest natural concentration; preferred for human nutrition |
| Xanthophyllomyces dendrorhous (yeast) | 中程度 | Faster production; primarily for aquaculture |
| Paracoccus carotinifaciens (bacteria) | 中程度 | Fermentation-derived |
| Synthetic | 該当なし | Petrochemical-derived; used in aquaculture feed |
Industry Standard: For human dietary supplements and cosmetics, natural astaxanthin from Haematococcus pluvialis is the premium choice due to its superior bioavailability and safety profile.
Astaxanthin’s exceptional antioxidant activity stems from its unique structure:
This allows astaxanthin to neutralize singlet oxygen and peroxyl radicals while protecting membrane phospholipids from peroxidation – a capability few other antioxidants possess.
| Health Benefit | 仕組み | 臨床的根拠 |
|---|---|---|
| Eye health | Reduces oxidative stress in retina; protects against blue light damage | Reduces eyestrain (CFF improvement) |
| Skin health | Protects from UV damage; reduces wrinkles and moisture loss | Improves skin elasticity and hydration |
| Joint health | Reduces inflammation and oxidative stress in synovium | Reduces joint pain and improves mobility |
| Cardiovascular | Lowers LDL oxidation; improves blood flow and lipid profile | Reduces triglycerides, increases HDL |
| Brain health | Crosses blood-brain barrier; reduces neuroinflammation | Improves cognitive function in aged adults |
| Sports performance | Reduces muscle damage and fatigue; speeds recovery | Decreases DOMS and lactate levels |
| 免疫サポート | Enhances NK cell activity | Reduces stress-induced immune suppression |
| 用途 | 機能 | Typical Concentration |
|---|---|---|
| Anti-aging creams | Protects from photoaging, reduces wrinkles | 0.01–0.1% |
| Sun care (oral + topical) | Enhances UV protection; reduces inflammation | Oral: 4–12 mg/day |
| After-sun lotions | Reduces erythema and oxidative damage | 0.05% |
| Eye serums | Reduces dark circles and puffiness | 0.01–0.05% |

Q: Natural vs. synthetic astaxanthin – what’s the difference?
A: Natural astaxanthin (from algae) is primarily the 3S,3’S isomer with higher biological activity. Synthetic astaxanthin contains a mixture of isomers (3S,3’S, 3R,3’R, and meso) and is not approved for human consumption in most markets. For human nutrition, always choose natural.
Q: What is the recommended daily dosage for supplements?
A: General wellness: 4–6 mg/day; Eye health: 6–12 mg/day; Sports recovery: 8–12 mg/day; Skin health: 6–8 mg/day. Always consult clinical data for specific formulations.
Q: Is astaxanthin stable in gummy formulations?
A: With proper stabilization (antioxidants, low moisture, opaque packaging), astaxanthin can maintain >90% potency for 18–24 months in gummies.
Q: Do you provide custom blends?
A: Yes. We offer private label and custom blending services for supplement manufacturers.
Q: 最小注文数量（MOQ）はどれくらいですか？
A: 100g for sample orders; 1kg for trial production; volume pricing available for 25kg+.
