What is Rhodiola Rosea Extract Powder?
Rhodiola Rosea represents the gold standard in adaptogenic botanicals — sourced from Rhodiola rosea, the species clinically validated in over 30 human trials. Every batch is cultivated under Strict Quality Control, extracted using water-based or hydro-ethanolic processes that preserve the critical 3:1 Rosavins-to-Salidroside ratio.
We offer two precision specifications to meet every formulation need:
Extract Powder delivers concentrated bioactive potency with standardized 3% Rosavins and 1% Salidroside at efficient 10:1 or 20:1 extraction ratios. Highly water-soluble with excellent capsule flow properties — ideal for high-speed encapsulation, nootropic shakes, and ready-to-drink (RTD) functional beverages.
Root Powder preserves the complete phytochemical matrix of the whole root at a natural 1:1 ratio, including all naturally-occurring cofactors and fibers that support “whole-spectrum” or “whole-food” label claims. Best suited for traditional tea blends, tablets, and tinctures.
Both formats are Non-GMO Project verified, Vegan and Gluten-Free certified, Allergen-Free, Kosher and Halal certified, manufactured under ISO 22000 and HACCP quality systems, and strictly third-party tested for lead, arsenic, cadmium, and mercury — meeting global safety standards including EU Pharmacopoeia and USP specifications.
Synergistic Formulation Tips: Blend with organic hemp protein, or combine with ashwagandha and pomegranate extract. To mask natural bitterness, pair with tart fruit powders (kiwi or pomegranate) or natural sweeteners (organic dextrose).

FAQ
Q: Is your Rhodiola extract from the correct species — Rhodiola rosea — or another species?
A: We guarantee Rhodiola rosea species. This is critical because only rosea contains the standardized 3:1 ratio of Rosavins to Salidroside. Other Rhodiola species (e.g., R. sacra, R. crassifolia) lack this specific phytochemical profile.
Q: Is ethanol or harsh chemicals used in your extraction process?
A: Our extracts use water-based extraction. We strictly adhere to standards, ensuring zero toxic solvent residues in the final powder. All batches are tested for residual solvents to <200 ppm ethanol.
Q: What are the advantages of Root Powder over Extract Powder?
A: Root Powder is preferred by formulators seeking “whole-spectrum” or “whole-food” label claims, as it contains all naturally-occurring cofactors and fibers from the plant — mimicking traditional medicinal use. It is best suited for herbal teas, tinctures, and formulations emphasizing traditional whole-plant credentials.
Q: How do you ensure heavy metal safety for a root crop?
A: Root crops can be bio-accumulators. Our Rhodiola is cultivated in controlled environments, and every batch undergoes strict third-party testing for lead, arsenic, cadmium, and mercury — meeting global safety standards including EU Pharmacopoeia and USP limits.
Q: What is the recommended dosage for each format?
A: Extract Powder (standardized 3% Rosavins / 1% Salidroside): 100–300 mg per serving. Root Powder (full-spectrum whole root): 500–1,000 mg per serving. Dosage depends on the desired potency and formulation type.
Q: Can I combine Rhodiola with other adaptogens?
A: Yes. Rhodiola rosea pairs synergistically with organic hemp protein, ashwagandha, pomegranate extract, and lion’s mane mushroom. Avoid combining with other stimulants if sensitivity is a concern.
Q: Does Rhodiola contain caffeine or other stimulants?
A: No. Rhodiola rosea is completely caffeine-free and does not contain any stimulant compounds.
Q: What is the MOQ, and what shipping options are available?
A: Minimum order quantity: 25 kg per specification. Free samples available with FEDEX, UPS, or EMS shipping. Lead time: 10–20 days. Payment methods: D/A, D/P, L/C, T/T, MoneyGram, Western Union, Credit Card. Departure ports: Qingdao or Tianjin.
