Rhodiola Rosea Extract

About bulk Rhodiola Rosea Extract

Rhodiola Rosea Extract is supplied as a Rhodiola rosea L. root extract powder, standardized to a minimum of 3.0% rosavins and 1.0% salidroside, both assayed by HPLC. It is sold in bulk by the kilogram, with pound and gram conversions available for quoting, so a requirement written in lb or g can be quoted without converting it first. Every lot is batch-numbered, and that number follows the material through to the paperwork that ships with it. Buyers comparing bulk rhodiola offers are usually checking the same three things: whether rosavins and salidroside are both specified, which method measured them, and whether the figures belong to the lot actually being offered rather than to a generic data sheet. Ask us to quote and you receive the specification together with the current lot's certificate of analysis, so both marker figures, the botanical source and the particle size can be checked against real material before a purchase order is raised.

Rhodiola Rosea Extract specifications

Specifications are taken from our own shipping and quality records. Figures are confirmed against the batch certificate of analysis at the time of quotation.

Formulating with Rhodiola Rosea Extract

The extract is supplied as a dry powder at 80 mesh and is used in capsules, tablets, dry powder blends and stick-pack powders. It is normally taken in at the blending stage; if it has to sit inside an existing blend or a particular dosage form, send that form and your target inclusion level with the enquiry and we will check the current lot against it before quoting. Because the material is specified by its rosavin and salidroside content, design against the figures on the lot certificate rather than a generic data sheet: both marker results sit on that document alongside loss on drying, heavy metals and microbiology, so a formula can be checked against the lot you actually receive. State the minimum marker levels your specification calls for when you request a quote, and we will check them against the current lot.

Sourcing and quality control

The material is held in U.S. stock and ships from our domestic warehouse network, which means a domestic lead time and domestic freight terms rather than an ocean booking and a customs entry. Send the quantity and delivery location with the enquiry and we will confirm availability and lead time in the quotation. Each lot carries its own batch number, and we supply that lot's certificate of analysis with the shipment or on request, so the assay, loss on drying, heavy metals and microbiology tie back to the material in front of you rather than to a generic specification. Shelf life is 36 months from date of manufacture, stored in a well-closed container away from moisture. On repeat orders the same batch numbering lets you set one delivery against the last and trace a finished-goods batch back to the rhodiola that went into it. We source through vetted, cGMP-compliant manufacturing partners.
