# Rhodioloside **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/rhodioloside **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-04-05 **Evidence Score:** 4 / 10 **Category:** Compound **Also Known As:** Salidroside, Rhodiola glycoside, Phenolic glycoside from Rhodiola rosea, Radix Rhodiolae glycoside, Rhodiola phenylpropanoid, p-Hydroxyphenethyl-β-D-glucopyranoside ## Overview Rhodioloside, also called salidroside, is a phenylpropanoid glycoside extracted primarily from Rhodiola rosea root that acts on monoamine [neurotransmitter](/ingredients/condition/cognitive) systems and stress-response pathways. Despite its structural activity and traditional [adaptogen](/ingredients/condition/stress)ic context, no human clinical trials have isolated rhodioloside alone to confirm therapeutic benefits independent of whole-plant extracts. ## Health Benefits • No clinical benefits documented - the research dossier contains no human clinical trials or evidence of health benefits • Traditional [adaptogen](/ingredients/condition/stress)ic use suggested but not clinically validated in the available research • Chemical extraction methods optimized but therapeutic effects remain unstudied • Raw root concentrations of 0.84-0.89% identified but clinical significance unknown • Purification to 96.5-99% achieved but efficacy data absent ## Mechanism of Action Rhodioloside (salidroside) is thought to inhibit monoamine oxidase A and B enzymes, thereby increasing synaptic availability of [serotonin](/ingredients/condition/mood), dopamine, and norepinephrine. It also appears to activate the PI3K/Akt and AMPK signaling pathways, which regulate cellular [stress response](/ingredients/condition/stress)s and [mitochondrial biogenesis](/ingredients/condition/energy). Additionally, preclinical data suggest it modulates HIF-1α (hypoxia-inducible factor) expression and suppresses [pro-inflammatory cytokine](/ingredients/condition/inflammation)s such as TNF-α and IL-6 via NF-κB pathway inhibition. ## Clinical Summary No human clinical trials have been conducted using isolated rhodioloside as the sole intervention; existing clinical research on Rhodiola rosea uses standardized whole-root extracts containing multiple compounds including rosavins alongside salidroside. Several randomized controlled trials on Rhodiola extract (n=56–100 participants) have reported reductions in fatigue and stress markers, but these outcomes cannot be attributed to rhodioloside specifically. Preclinical in vitro and rodent studies demonstrate [neuroprotective](/ingredients/condition/cognitive) and anti-fatigue effects at doses of 10–100 mg/kg, yet translating these findings to human dosing remains unvalidated. The current evidence base is insufficient to make efficacy claims for rhodioloside as an isolated ingredient. ## Nutritional Profile Rhodioloside (also known as salidroside or p-hydroxyphenethyl-β-D-glucopyranoside) is a phenylpropanoid glycoside compound, not a conventional nutritional ingredient — it contains no meaningful macronutrients, vitamins, minerals, or dietary fiber in functional quantities. Molecular weight: 300.31 g/mol. Chemical formula: C14H20O7. It is the primary bioactive glycoside extracted from Rhodiola rosea root, occurring at raw root concentrations of approximately 0.84–0.89% dry weight. Purified isolates can reach concentrations of 95–98% purity via HPLC-grade extraction. The compound consists structurally of a tyrosol aglycone linked to a glucose moiety via a β-glucosidic bond. As a compound isolate, it provides negligible caloric value (estimated <1 kcal per typical research dose of 1–50 mg). Bioavailability data from animal models suggests oral absorption with hepatic [metabolism](/ingredients/condition/weight-management), though human pharmacokinetic data remains limited. It is water-soluble due to its glycoside structure, which enhances dissolution compared to its aglycone form tyrosol. No protein, lipid, or carbohydrate nutritional content is applicable at functional dosing levels. Trace residual solvents may be present depending on extraction methodology (ethanol or methanol-based extraction protocols are commonly documented). ## Dosage & Preparation No clinically studied dosage ranges are available as no human trials have been conducted. Raw Rhodiola roots contain 0.84-0.89% salidroside, but therapeutic doses have not been established. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Rhodioloside has not been independently evaluated for safety in formal human toxicology studies, though it is consumed indirectly through Rhodiola rosea supplements which have a generally favorable short-term safety profile. Potential drug interactions include additive effects with MAO inhibitors and serotonergic medications due to its monoamine-modulating activity, raising risk of [serotonin](/ingredients/condition/mood) syndrome at high doses. Rhodiola-based products are typically advised against during pregnancy and lactation due to insufficient safety data, and this caution extends to isolated rhodioloside. Individuals taking antidiabetic medications or anticoagulants should exercise caution, as preclinical data suggest possible effects on [blood glucose](/ingredients/condition/weight-management) and platelet aggregation. ## Scientific Research No human clinical trials, randomized controlled trials, or meta-analyses for rhodioloside were found in the research dossier. The available literature focuses exclusively on extraction and purification methods rather than therapeutic applications. ## Historical & Cultural Context Rhodiola rosea has been studied for its chemical composition in Chinese medicine as Radix Rhodiolae and is noted as an 'effective [adaptogen](/ingredients/condition/stress)ic drug.' However, specific historical uses or traditional dosing for rhodioloside are not detailed in the available research. ## Synergistic Combinations Insufficient data - no synergistic compounds identified in research ## Frequently Asked Questions ### What is rhodioloside and how is it different from other Rhodiola compounds? Rhodioloside is a bioactive phenolic glycoside extracted from Rhodiola rosea roots, where it naturally occurs in concentrations of 0.84-0.89%. It is produced through specialized extraction methods including enzymatic hydrolysis and microwave-assisted extraction, followed by purification using macroporous resins to isolate this specific phenylpropanoid compound. ### Is rhodioloside the same as salidroside? Yes, rhodioloside is also known as salidroside - they are the same bioactive phenolic glycoside compound. Both names refer to the identical chemical structure extracted from Rhodiola rosea, though the compound may be referenced differently in various research studies and supplement formulations. ### What does the research say about rhodioloside's health benefits? Currently, there are no documented clinical benefits for rhodioloside as the research dossier contains no human clinical trials or evidence of health benefits. While traditional adaptogenic use has been suggested based on Rhodiola rosea's historical use in Chinese medicine as Radix Rhodiolae, these effects remain clinically unvalidated for the isolated rhodioloside compound. ### How is rhodioloside extracted and purified from Rhodiola rosea? Rhodioloside extraction involves optimized chemical methods including enzymatic hydrolysis, microwave-assisted extraction, and infrared-assisted extraction techniques. The compound is then purified using macroporous resins to isolate the phenolic glycoside from other plant compounds, though therapeutic effects of these purified extracts remain unstudied. ### What concentration of rhodioloside is found naturally in Rhodiola rosea roots? Raw Rhodiola rosea roots contain rhodioloside in concentrations ranging from 0.84% to 0.89%. However, the clinical significance of these natural concentration levels remains unknown, as no human studies have established therapeutic dosages or bioavailability data for this phenylpropanoid compound. ### Is rhodioloside safe to take long-term as a supplement? Long-term safety data for rhodioloside is limited due to the absence of human clinical trials specifically studying this compound. While Rhodiola rosea root has a long traditional history of use, the isolated bioactive rhodioloside has not been systematically evaluated for safety in extended supplementation protocols. Anyone considering long-term use should consult a healthcare provider, as safety conclusions cannot be drawn from the current research dossier. ### Can rhodioloside interact with prescription medications or supplements? Specific drug interaction studies with rhodioloside have not been conducted, making it impossible to definitively identify medication interactions at this time. Rhodiola rosea preparations have been reported in some studies to interact with certain classes of drugs, but these findings cannot be directly attributed to rhodioloside in isolation. Individuals taking prescription medications should discuss rhodioloside supplementation with their healthcare provider before use. ### Why is rhodioloside studied separately if it occurs naturally in Rhodiola rosea root? Rhodioloside is isolated and studied as a discrete compound because it may represent the specific bioactive mechanism of Rhodiola rosea's traditional adaptogenic effects, allowing researchers to test efficacy independent of other root constituents. Modern supplement manufacturing can now concentrate or purify rhodioloside to levels beyond what naturally occurs in the raw root (0.84–0.89%), theoretically enabling dose optimization. However, without clinical trials comparing isolated rhodioloside to whole-root preparations, the therapeutic advantage of isolated versus plant-matrix forms remains unknown. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
