Bulk Liposomal Rhodiola Rosea Extract Powder 50% 70% Standardized Rosavins Salidroside OEM Factory Supply
LIPOSOMAL
RHODIOLA ROSEA
EXTRACT POWDER
A liposomal delivery format of standardized Rhodiola rosea root extract, manufactured under GMP protocols for consistent rosavins and salidroside content. Available in two potency grades — 50% and 70% — to match diverse formulation requirements, with full OEM flexibility for B2B supplement and beverage brands.
TECHNICAL SPECIFICATIONS
BOTANICAL ORIGIN
Rhodiola rosea is a perennial flowering plant in the Crassulaceae family, native to the cold, high-altitude regions of the Arctic, Scandinavia, Siberia, and the mountainous areas of Central Asia and the Tibetan Plateau. The root and rhizome — the harvested botanical parts — have been documented in traditional herbal practices for centuries.
Today, standardized Rhodiola rosea extracts are characterized by two key marker groups: rosavins (rosavin, rosarin, rosin) and salidroside. These phenylpropanoid glycosides and phenylethanol derivatives form the basis of modern extract standardization and quality assessment.
Our extract is produced from sustainably harvested Rhodiola rosea root, processed through food-grade ethanol/water extraction to preserve the native marker profile. The resulting standardized extract is then encapsulated within phospholipid bilayers to improve aqueous dispersibility for industrial manufacturing ease.

FUNCTIONAL BENEFITS
*These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.
1. Consistent Marker Profile for Reliable Formulating
Standardized extracts simplify product development. With a defined rosavins and salidroside content at your chosen potency (50% or 70%), formulators work with predictable input data rather than variable whole-herb powders.
2. Liposomal Format for Manufacturing Compatibility
Phospholipid encapsulation converts a hydrophobic plant extract into a water-dispersible powder. This broadens the range of delivery formats — from instant drink mixes and effervescent tablets to stick packs and liquid shots.
3. Two Potency Options for Formulation Flexibility
The 50% grade provides cost-efficiency for high-volume applications. The 70% high-potency grade allows smaller inclusion rates per serving, giving brands flexibility in capsule fill weight and formulation space.
4. Quality-Driven Supply Chain
Raw material traceability to known Rhodiola rosea growing regions, in-house HPLC testing of each incoming lot before extraction, and batch-level COA documentation support the due diligence requirements of B2B buyers.
INDUSTRIAL APPLICATIONS
1. Dietary Supplement Formulations
Two standardized potencies for capsule, tablet, and softgel filling at precise active loading targets.
2. Functional Beverages
Water-dispersible profile enables incorporation into powdered drink mixes, stick packs, RTD shots, and effervescent formats.
3. Gummy & Soft Chew Manufacturing
Encapsulated format helps mask the inherent bitterness of Rhodiola extract, supporting palatability in chewable dosage forms.
4. Combination / Multi-Ingredient Blends
Compatible with co-formulation alongside vitamins, minerals, amino acids, and other botanical extracts in complex nutraceutical matrices.
5. Contract Manufacturing / OEM
Ready-to-use liposomal Rhodiola rosea powder supplied in bulk, with OEM flexibility on potency, packaging, and label customization.

TECHNICAL FAQ
Q1: What is the difference between the 50% and 70% grades?
Both grades are standardized for total rosavins plus salidroside content. The 50% grade is cost-optimized for high-volume formulations; the 70% grade offers higher potency per gram, allowing smaller inclusion rates and more compact dosage forms.
Q2: Is this product water-soluble?
Rhodiola rosea extract itself has limited water solubility. The liposomal encapsulation transforms it into a water-dispersible powder that forms a uniform suspension when mixed with water or aqueous systems.
Q3: How is the rosavins and salidroside content verified?
Each production batch is tested by HPLC against USP reference standards for rosavin, rosarin, rosin, and salidroside. Results are documented in the batch-specific Certificate of Analysis provided with each shipment.
