Alginate Oligosaccharide (AOS) – Frequently Asked Questions (FAQ)

1. What is Alginate Oligosaccharide (AOS)?

Alginate Oligosaccharide (AOS) is a low-molecular-weight bioactive oligosaccharide derived from brown seaweed alginate through enzymatic degradation. It offers improved solubility, absorption, and biological activity compared to natural alginate.

---

2. How is AOS produced?

AOS is obtained by enzymatic hydrolysis of brown alginate using β-eliminase alginate lyases. This eco-friendly process ensures controlled polymerization (DP 2–7) and consistent quality with molecular weight below 1000 Da.

---

3. What are the main functions and benefits of AOS?

AOS exhibits multiple biological activities, including:

• Prebiotic and gut health support

• Immune regulation and antioxidant activity

• Anti-inflammatory and antibacterial effects

• Skin brightening and anti-aging support

• Metabolic and plant-growth-promoting properties

---

4. What industries commonly use AOS?

AOS is widely used in:

• Nutraceuticals & Functional Foods – for gut, immune, and metabolic support

• Cosmetics – for moisturizing, soothing, and anti-aging formulations

• Pharmaceuticals – as a bioactive polysaccharide for immune and antioxidant use

• Agriculture – as a plant-growth promoter and stress tolerance enhancer

---

5. What are the specifications and purity levels?

Our AOS products are available in various purity levels (≥90%) and molecular weights (<1000 Da). Customizable grades for food, cosmetic, or pharmaceutical use are available upon request.

---

6. Is AOS safe for human use?

Yes. AOS is naturally derived, non-toxic, and biodegradable, with excellent biocompatibility. It has been validated in multiple studies for safe use in foods, cosmetics, and health products.

---

7. How does AOS differ from regular alginate?

Unlike high-molecular-weight alginate, AOS is more soluble, absorbable, and bioactive, offering superior physiological and functional benefits for human and plant applications.

---

8. What are the recommended applications and dosages?

• Functional foods / supplements: 100–500 mg per day

• Cosmetic formulations: 0.1–2% concentration

• Agricultural use: variable depending on crop and formulation

---

9. How should AOS be stored?

Store in a cool, dry, and sealed container, away from direct sunlight and moisture. Under proper conditions, AOS remains stable for up to 24 months.

---
