Bulk Rhodiola Rosea Root Extract for Supplement Manufacturing
Rhodiola rosea extract is a dry powder made from the root and rhizome of Rhodiola rosea L., a flowering plant in the stonecrop family. It is usually standardized to rosavins and salidroside, measured by HPLC. We supply it in bulk to supplement brands, contract manufacturers, and formulators, with lot documents for your quality team.
A well defined root extract for capsule and powder formulas
Rhodiola rosea extract is easy to specify. It has named marker compounds, standard test methods, and a long record in the supplement trade. That makes lot to lot comparison simple for buyers and quality teams.
Clear marker compounds
Rosavins (rosavin, rosarin, and rosin) and salidroside are the compounds most specifications name. They give you a measurable target for every lot.
Species identity you can check
Rosavins are the reference markers used to tell Rhodiola rosea apart from related Rhodiola species. An HPTLC fingerprint against a reference standard confirms identity.
Familiar market grades
The most widely listed grade is 3% rosavins with 1% salidroside. Higher grades, such as 5% rosavins with 3% salidroside, are also traded for formulas that need a smaller fill weight.
Fine, free flowing powder
Most spec sheets call for a powder that passes a 60 to 80 mesh screen. That suits capsule filling, tableting, and dry blending.
Water and ethanol extraction
Standard extracts are made with water and ethanol, then dried to a powder. The native ratio is often about 10 to 12 parts root to 1 part extract.
Documented trade status
All Rhodiola species are listed in CITES Appendix II. International shipments of bulk root and extract travel with CITES export permits, which gives you a paper trail back to the source.
Where formulators use rhodiola rosea extract
This extract fits measured formats where fill weight and serving size are controlled, including:
- Capsules
- Compressed tablets
- Single ingredient powders
- Multiple ingredient botanical blends
- Stick packs and sachets
- Powdered drink mixes
- Gummies, after taste and stability trials
- Private label programs
Plan fill weights from the confirmed assay on each COA. A 3% rosavins extract and a 5% rosavins extract are not interchangeable gram for gram, so recalculate your serving math whenever you change grades.
What to check before you buy rhodiola rosea extract
Two powders sold under the same name can differ in species, plant part, solvent, and assay method. Review these points together, and ask for lot documents before you approve a supplier.
Species and plant part
Confirm Rhodiola rosea L. root and rhizome on both the specification and the certificate of analysis (COA). Other species, such as Rhodiola crenulata, are sold in the same markets.
Identity by HPTLC
An HPTLC fingerprint compared with a reference standard confirms the species. It also shows whether the rosavin bands are present, which is the clearest sign of true Rhodiola rosea.
Assay method and basis
Ask whether rosavins and salidroside are measured by HPLC, and whether results are on a dry or as is basis. A UV result for total polyphenols is a different measure.
Solvent, ratio, and carrier
Confirm the extraction solvent and native extract ratio. Ask whether any carrier, such as maltodextrin, is added to reach the stated grade.
Contaminant limits
Check heavy metals by ICP-MS, microbial limits by USP methods, pesticide residues, and residual solvents. Compare each limit with your own finished product specification.
Origin and CITES paperwork
Ask for the country of harvest and whether the root was cultivated or wild collected. The answer shapes both the CITES permit and your supplier file.
Label math: If your label lists rosavins per serving, base the number on each lot's measured assay and your own finished product testing. A stated grade is a minimum, so the measured value on the COA is the figure to work from.

These values reflect the common 3% rosavins grade. Final figures come from the specification sheet and COA for your lot. NLT means not less than, and NMT means not more than.

Storage and handling for bulk rhodiola extract
Botanical extracts keep best when they stay sealed, dry, and out of light. These steps keep the powder in good condition between production runs.
Keep it sealed
Close the inner liner after each use and press out the air. Extract powders pick up moisture from the air and can cake when left open.
Store cool and dry
Keep bags off the floor in a dry room, away from heat sources. Follow the temperature range on the spec sheet.
Keep away from light
Leave the powder in its original opaque packaging. Light and heat can shift color and assay over time.
Rotate stock
Record the lot number and retest date for each bag. Send older lots to production first.
Rhodiola rosea extract buyer FAQ
Quick answers to the questions procurement and quality teams ask most.
What is the difference between rosavins and salidroside?
Both are natural compounds in rhodiola root. Rosavins are the markers used to identify Rhodiola rosea specifically, while salidroside also occurs in other Rhodiola species. Specifications usually state a minimum for each, measured by HPLC.
Which grade should I choose, 3% or 5% rosavins?
The 3% rosavins grade is the most widely listed and the easiest to source. A higher grade lets you use less powder per serving. Choose based on your label target, capsule size, and cost per finished serving.
Is rhodiola extract the same as rhodiola root powder?
No. Root powder is dried, milled root. Extract is made by soaking the root in a solvent and drying the liquid into a concentrated powder with a stated assay. Extract is the usual choice when a label needs a standardized amount.
Does bulk rhodiola need CITES paperwork?
Yes, for international trade. All Rhodiola species have been listed in CITES Appendix II since 2023. Bulk roots and extracts that cross borders need export permits, while finished products packaged for retail sale are excluded.
What documents can I get with an order?
Select testing documents on the quote form and we will send what is available for the lot.
Can I get a sample before a bulk order?
Yes. Choose sample options on the quote form and we will confirm size and timing.
How should I store an opened bag?
Close the liner, press out the air, and keep the bag in a cool, dry place away from light. Use the powder within the shelf life shown on the COA.
