BUYER DECISION GUIDE
When to Select the 7% Withanolides Grade
Select this grade when the purchasing specification requires a root extract quantified to 7% withanolides by HPLC. Do not treat raw ashwagandha powder, ratio extracts and standardised HPLC grades as interchangeable. Confirm botanical identity, plant part, analytical method and the offered-batch result before approval.
- Evaluation samples: typically 10–20 g, subject to stock
- Regular MOQ: typically 1 kg
- Common packing: 1 kg bag; bulk packing confirmed separately
- Typical lead time: 7–15 working days after order confirmation
- Private-label and specification consultation available

QUALITY & DOCUMENTATION
Batch Verification for B2B Qualification
The reviewed representative COA records 7.12% withanolides by HPLC, 4.18% loss on drying and 3.69% ash, together with particle-size, heavy-metal and microbiological controls. Buyers should request the current offered-batch COA and may arrange independent testing before a commercial order.
The Ashwagandha Spectrum — Matching Standardization to Your Claim
Application / Formulation Example: Ashwagandha is the anchor of the adaptogen category, but “ashwagandha” is not one ingredient — it is a spectrum. Match the form to your claim:
- 7% withanolides extract: premium stress & sleep formulas (150–300 mg/day is a common dose for clinical-style studies)
- 5% withanolides extract: cost-efficient stress-support daily formulas
- 10:1 root extract: traditional-use positioning, higher dosing volume
- Root powder: whole-herb, “full spectrum” positioning
A typical night-time stress formula: 300 mg ashwagandha KSM-66-type (7% withanolides), 200 mg L-theanine, 150 mg magnesium glycinate, and 10 mg lemon balm extract.
Spec Comparison:
| Parameter | 7% Withanolides | 5% Withanolides | 10:1 Extract | Root Powder |
|---|---|---|---|---|
| Marker level | 7.0% (COA) | 5.0% (COA) | 10:1 ratio | Whole root |
| Typical dose | 150–300 mg | 300–500 mg | 300–500 mg | 500–1000 mg |
| Best for | Clinical-style claims | Everyday stress | Traditional positioning | Budget / full-spectrum |
Market Context: Ashwagandha remains one of the top-selling adaptogens globally; the growth focus has shifted from “does it work” to “which standardization and dose supports which claim.” Offering the full spectrum (7%/5%/10:1/powder) lets buyers choose by claim and price point. (Qualitative trend.)
FREQUENTLY ASKED QUESTIONS
Ashwagandha Extract Purchasing FAQ
Is the declared percentage a specification limit or a measured result?
The specification figure is Withanolides 7% by HPLC; the measured result for your lot is reported separately on its COA.

Which botanical identity is declared for Ashwagandha Extract Powder 7% Withanolides?
It is declared as Withania somnifera / winter cherry.
Which mesh size can you supply?
98% through 100 mesh as standard; other sizes are reviewed against your sieving or blending step.
Which safety parameters are tested every lot?
Moisture ≤5.0%, ash ≤5.0%, heavy metals and microbiology against the approved specification.
Can I get a sample before placing the order?
Yes. An evaluation sample is normally available before a formal order. Sample quantity, courier account and destination are confirmed at the time of request.
What packing options are available?
Standard packing is a sealed food-grade inner liner inside an export carton or fibre drum. Pack size, labelling and private-label artwork are agreed in the written specification.
What is the minimum order quantity?
The regular MOQ is typically 1 kg. An evaluation sample of 10-20 g can usually be arranged before a formal order, subject to stock.
