Liposomal Silymarin 50% & 70% SILYMARIN EXTRACT | Sunflower Lecithin + Phytosterols System Advanced Liposomal Delivery

Product Identity | Core Composition & Delivery Form

Liposomal Silymarin is a high-bioavailability milk thistle extract engineered into a phospholipid-based delivery system to overcome the intrinsic absorption limitations of conventional silymarin.

• Active Ingredient: Silymarin (from Silybum marianum seed extract)
• Assay: 50% / 70% (customizable)
• Dosage Form: Liposomal powder (water-dispersible)
• Carrier System: Sunflower Lecithin + Phytosterols
• Appearance: Yellow to light yellow fine powder
• Structure: Nano-scale lipid vesicles (confirmed by TEM imaging)

Designed specifically for nutraceutical, pharmaceutical, and functional formulation applications requiring enhanced liver bioactivity.

Absorption Breakthrough | From Poor Solubility to Efficient Uptake

Silymarin is widely recognized for liver health support, yet its commercial effectiveness is limited by:

• Extremely low water solubility
• Poor intestinal permeability
• Rapid metabolism and clearance

This results in low oral bioavailability (<30%) in conventional extracts.

Liposomal Solution

By encapsulating silymarin within phospholipid bilayers:

• Liposomes mimic cell membranes, improving intestinal transport
• Active compounds are protected from degradation
• Direct delivery into systemic circulation is enhanced

➡ Result: 2–5× higher bioavailability compared to standard silymarin extract

FAQ | Buyer-Focused Technical Clarifications

1. What makes liposomal silymarin different from regular extract?
Liposomal silymarin uses phospholipid encapsulation to significantly improve absorption and protect the active compounds during digestion.

2. Does this product disperse in water?
Yes, the powder is designed to form a stable dispersion in water, making it suitable for beverages and liquid formulations.

3. Which carrier system should I choose?
For most nutraceutical applications, lecithin + plant sterols offers the best balance of stability and cost-efficiency.

4. How stable is the liposomal structure over time?
The product maintains stability under recommended storage (2–8°C, protected from light), with low moisture and stable encapsulation.

5. Can you provide structural proof of liposomals?
Yes, TEM imaging is available to verify vesicle formation and morphology.

6. Is this suitable for EU and US markets?
Yes, non-GMO sunflower lecithin and full documentation support compliance in major global markets.

7. Can I request a customized formulation?
Absolutely. Active content, carrier system, particle size, and dosage form can all be tailored.

8. What is the shelf life and storage condition?
Shelf life is typically 18–24 months, stored in a cool, dry, sealed environment (recommended 2–8°C).
