Rhodiola Rosea Extract (3% Rosavins / 1% Salidroside): Bulk B2B Wholesale Supplier
Valeherb supplies standardized Rhodiola rosea extract — 3% rosavins / 1% salidroside by HPLC — for nootropic, sports nutrition, adaptogen supplement, and functional food formulations. Rhodiola is an adaptogen that has been studied in research for activity on the body’s stress-response pathways at the hormonal and neurochemical level, through mechanisms that research describes as distinct from stimulant-type compounds.[1] This dual-marker specification mirrors the phytochemical profile used across published clinical trials and is the baseline most buyers require to align a finished product with that trial evidence.
Active Compounds and Standardization
Rhodiola rosea (Arctic root, golden root) is a primary adaptogen native to high-altitude cold-climate regions of Siberia, Scandinavia, and the Tibetan Plateau. Its pharmacological activity comes from two compound classes that must be verified separately by HPLC:
| Compound | Activity Studied in Research | Minimum Standard |
|---|---|---|
| Rosavins (Rosavin, Rosarin, Rosin) | Studied for HPA-axis modulation and stress- and fatigue-related endpoints in research; species-specific to R. rosea — absent in R. crenulata and other cheaper substitutes, making rosavins the key authenticity marker[1] | ≥3% by HPLC |
| Salidroside + Phenolic Complex | Studied for neuroprotective and anti-fatigue activity in research. MAO-modulating activity is attributed to the full phenolic complex — rosiridin, rhodiocyanosides, and salidroside acting collectively — not to rosavins alone[3] | ≥1% by HPLC |
Available Grades and Specifications
Valeherb supplies Rhodiola rosea extract (CAS 97404-52-9) in two grade families. MOQ is 1 kg for both. The choice depends on whether your formulation needs marker-quantified material that matches the published trial profile, or a cost-effective concentration ratio for general-wellness positioning.
| Grade | Assay | Identity Control | Typical Application |
|---|---|---|---|
| Standardized Extract | 3% Rosavins / 1% Salidroside by HPLC | Dual-marker HPLC quantification; matches the profile used in published clinical trials | Adaptogen & stress-support supplements, nootropic/cognitive formulas, sports-nutrition products |
| Ratio Extract | 10:1 and 20:1 concentration ratio | HPLC fingerprint for identity (not quantified to fixed rosavin/salidroside %) | General-wellness supplements, functional foods & beverages, cost-effective formulations |
Clinical Evidence
Rhodiola rosea is one of the few adaptogens with multiple peer-reviewed RCTs specifically examining stress-related fatigue and cognitive performance — not just general wellbeing. The trials below characterise the standardized extract; they are not claims for any finished product. Four references anchor the evidence base:
A randomized, double-blind, placebo-controlled trial by Olsson et al. (2009) dosed 576 mg/day of standardized extract (SHR-5) for 28 days in subjects with stress-related fatigue. The treatment group showed statistically significant reductions in fatigue and improvements in concentration, alongside a reduced cortisol response to awakening stress, versus placebo.[5]
Darbinyan et al. (2000) reported that a single dose of standardized Rhodiola extract significantly improved measures of mental fatigue, associative thinking, short-term memory, and calculation speed in physicians performing night-shift work — a real-world cognitive-load condition.[2]
De Bock et al. (2004) found that 200 mg taken one hour before exercise significantly increased time-to-exhaustion and reduced perceived exertion versus placebo in a double-blind crossover design — relevant to sports-nutrition applications.[4]
A systematic review by Ishaque et al. (2012) covering 11 RCTs reported a favorable safety profile across all included studies and improvements in physical and mental fatigue measures in most trials.[6]
Formulation Applications and Dose Reference
The doses below reflect amounts used in published research and are a formulation reference only — not therapeutic recommendations. Finished-product dosing and any associated claims are the responsibility of the marketer.
| Application | Dose Used in Studies | Formulation Notes |
|---|---|---|
| Stress & adaptogen supplements | 400–600 mg/day[5] | Vegan capsule, split AM/midday. Pairs with Ashwagandha KSM-66, Eleuthero, Schisandra for comprehensive adaptogen stacks |
| Nootropic & cognitive formulas | 200–400 mg/serving[2] | Complements L-theanine, B vitamins, lion’s mane; commonly used alongside caffeine in cognitive blends |
| Sports nutrition | 200 mg acute, 60–90 min pre-workout[4] | Not listed on the WADA Prohibited List (verify the current list at sourcing). Compatible with powder blends, RTD beverages, and chew formats |
| Functional foods & beverages | 100–200 mg/serving | Heat-stable extract grades available. Mild bitter profile; natural flavor masking recommended at higher concentrations |
Sourcing Criteria
| Criterion | What to Require |
|---|---|
| Dual HPLC Standardization | Separate batch-level values for rosavins (≥3%) and salidroside (≥1%) — bundled total saponin readings are insufficient to confirm equivalence to the trial material |
| Species Authentication | Rosavin presence confirms R. rosea. Request crenulatin testing by NMR or HPLC-UV — crenulatin is a coumarin unique to R. crenulata, detected in 2 of 4 commercial products in a 2020 analytical study, in which fewer than one quarter of products confirmed their labeled rosavin and salidroside amounts[7] |
| Third-Party COA | Per-batch: rosavins, salidroside, heavy metals (USP <232>), pesticide residues, microbial limits (USP <2021>), moisture |
| Geographic Origin | Siberia, Scandinavia, or high-altitude Tibetan Plateau preferred. Request harvest origin documentation — growing conditions directly influence bioactive concentration |
| Certifications | ISO, HACCP, GMP, BRC, Kosher, Halal, and Organic available; manufactured in an FDA-registered facility for US DSHEA supply chains. Confirm Non-GMO and the specific certificate scope per batch/market |
Regulatory Status
- US (DSHEA): Rhodiola rosea extract is a lawful dietary-supplement ingredient. Structure/function claims (e.g., stress support, mental performance) must be self-substantiated by the marketer and carry the FDA disclaimer; published RCTs on the standardized extract can contribute to that substantiation. Disease treatment or prevention claims require drug (NDA) approval
- EU: Registered as a traditional herbal medicinal product under Directive 2004/24/EC; traditional-use registration covers indications such as temporary symptoms of stress and fatigue. Claims beyond the traditional-use scope require full marketing authorization
- Canada (NHPs): A Health Canada NNHPD monograph exists for Rhodiola, with permitted claims in the area of stress tolerance and mental performance, subject to meeting the monograph conditions
