Product Overview
Pharmaceutical-Grade Ashwagandha Extract (Withanolides)
Manufactured by Xi'an Tihealth Biotechnology Co., Ltd.
Xi'an Tihealth is a leading global B2B manufacturer of highly purified Ashwagandha Extract (Withania somnifera), often referred to as Indian Ginseng. Recognizing its profound adaptogenic properties, we source our raw materials exclusively from authentic, heavy-metal-free cultivation bases, utilizing the nutrient-dense roots to ensure a superior active profile.
Through our advanced low-temperature extraction and precision chromatographic purification, we isolate and standardize the plant's core therapeutic compounds: Withanolides. Available in customizable concentrations (ranging from 2.5% to 10% HPLC), our fine brown-yellow powder demonstrates exceptional stability and bioavailability. It acts as a foundational Active Pharmaceutical Ingredient (API) for premium stress-relief supplements, testosterone and vitality support capsules, and advanced sports nutrition formulas.

Manufacturing & Processing Excellence
Root-Specific Extraction
While cheaper extracts use the entire plant (including leaves which contain Withaferin A), Tihealth extracts exclusively from the roots. This ensures a high concentration of the specific Withanolides responsible for the most potent adaptogenic and stress-relieving effects, mirroring traditional Ayurvedic practices.
Targeted Withanolide Enrichment
Utilizing advanced macroporous resin column chromatography, we successfully remove inactive starches and impurities. This allows us to enrich the Total Withanolides to precise, pharmaceutical-grade concentrations ranging from 2.5% up to 10% (verified by HPLC).
Zero Toxic Solvents
We strictly abandon harsh chemical solvents. Relying on a food-grade Ethanol-Water system and advanced vacuum evaporation, we ensure solvent residues remain strictly <50ppm, guaranteeing a safe, clean-label ingredient compliant with global standards.
Evidence-Based Physiological Benefits
HPA Axis Regulation & Stress Management
Recognized globally as a premier adaptogen. Ashwagandha actively regulates the Hypothalamic-Pituitary-Adrenal (HPA) axis, significantly reducing serum cortisol levels. It provides clinical support in alleviating chronic stress, anxiety, and stress-induced insomnia.
Testosterone & Vitality Support
Clinical trials demonstrate that high-yield Withanolides can stimulate DHEA-S and luteinizing hormone, leading to improved natural testosterone production in men. This enhances physical vitality, muscle recovery, and overall reproductive health.
Cognitive & Neurological Function
Exhibits potent neuroprotective properties. It promotes antioxidant activity in the brain, improving memory consolidation, executive function, and reaction speed while offering supportive therapy against early-stage cognitive decline.
Systemic Anti-Inflammatory Properties
The active constituents effectively inhibit pro-inflammatory cytokines (such as COX-2). This makes it valuable in both topical cosmetic applications (reducing acne and photoaging) and oral formulations for alleviating joint discomfort.
Industrial Formulation Applications
Stress & Sleep Nutraceuticals
The core API for formulating premium "anti-stress" capsules, adrenal fatigue support blends, and non-sedative sleep aids (often paired with L-Theanine or Magnesium).
Sports Nutrition & Men's Health
Extensively utilized in pre-workout powders, testosterone boosters, and muscle recovery formulas to enhance physical endurance and reproductive vitality.
Functional Foods & Beverages
Our specialized water-soluble modifications allow for seamless integration into energy bars, adaptogenic coffees, and relaxation RTD (Ready-To-Drink) beverages.
Cosmeceuticals & Skincare
Acts as a potent botanical active in anti-aging creams and serums. It inhibits UV-induced oxidative damage and soothes inflammatory acne in sensitive skin formulations.

Formulator & Procurement FAQ
01. What is the active compound in your Ashwagandha Extract?
The primary bioactive compounds are Withanolides, a group of naturally occurring steroidal lactones. We utilize HPLC to precisely quantify and standardize their concentration, ensuring you receive a highly potent, adaptogenic API.
02. Are your extracts derived from the root or the leaves?
We extract exclusively from the roots of Withania somnifera. In traditional Ayurvedic medicine and modern clinical research, the root is prioritized for safety and efficacy, as the leaves contain high levels of Withaferin A, which can be cytotoxic at higher doses.
03. What is the batch-to-batch variation of Withanolides?
Through stringent online monitoring during the extraction process, we control the batch deviation of Total Withanolides to within ±3%. Precise analytical data is documented on every Certificate of Analysis (COA).
04. Does the extract cause any toxicity to the liver?
Standardized root extracts are generally recognized as safe (GRAS). However, high-dose, long-term consumption has been associated with rare cases of liver stress. We recommend formulating within the clinically studied dosage range (typically 250mg - 600mg daily) and including appropriate cautionary labels for consumers with pre-existing hepatic conditions.
05. What is the Minimum Order Quantity (MOQ) and lead time?
MOQ for commercial mass production is 25kg (standard cardboard drum). Standard extracts are dispatched within 7-10 days. Samples (10g-1kg) are available for your R&D formulation trials upon request.
