Every ashwagandha brief eventually reaches the same fork: license a branded extract with its clinical dossier and its mark on the pack, or source a generic standardised extract and own the specification. Both are sound choices. This comparison sets them side by side on the facts the brand owners themselves publish, so the decision is made on the product, not the sales deck.
The four options
| Extract | Plant part | Standardisation (owner’s published basis) | Commercial model |
|---|---|---|---|
| Generic standardised root extract (e.g. SV Botanica) | Root only | 2.5% by HPLC; 5% gravimetric with HPLC profile; 10% HPLC on request | Unbranded; buyer sets the specification and owns the label; priced per kg |
| KSM-66® (Ixoreal Biomed) | Root only | 5% withanolides by HPLC, full-spectrum positioning | Branded; licensed use of the mark; sourced from the owner or its distributors |
| Sensoril® (Natreon) | Root and leaf | 10% withanolide glycosides by HPLC | Branded; low-dose positioning |
| Shoden® (Arjuna Natural) | Root and leaf | 35% withanolide glycosides by HPLC | Branded; high-concentration, low milligram dose |
KSM-66, Sensoril and Shoden are trademarks of their respective owners. Figures are quoted from the owners’ published specifications for comparison only; SV Botanica does not supply these branded ingredients.
What you are buying with a brand
Three things: a clinical dossier on that specific extract, which lets you point to studies on the ingredient you actually use; a consumer-facing mark that retailers and some shoppers recognise; and a fixed specification that you cannot change and do not have to defend. The price of those three things is a per-kilogram premium and a licence agreement that governs how the mark is used, and in some cases minimum volumes.
What you are buying with a generic
Control and margin. You write the specification — plant part, assay method, withaferin A cap, residue panel — and the supplier meets it or does not. You can second-source. You keep the label your own. What you do not get is a study on your ingredient; the human evidence on ashwagandha root extract is real and growing, but it attaches to the class, not to your drum, and a careful marketer words the claim accordingly. The generic route also asks more of your quality function: the specification has to be written and the COA has to be read, which is what our COA guide is for.
Plant part is a real difference
Two of the branded extracts use leaf as well as root. That is a deliberate formulation choice by their owners and their safety data is theirs to present; it also means a buyer whose own specification says “root only” cannot use them. A generic root-only extract with withaferin A reported keeps that door closed by design.
When to choose which
- Branded, when the clinical claim is the product story, when a retailer asks for a named ingredient, or when your quality team would rather inherit a specification than write one.
- Generic, when you control the specification, when price per active matters, when you need a second source, when you sell under your own brand into markets that do not recognise the ingredient marks, or when your format needs a grade the brands do not offer.
- Both, more often than people admit: a branded extract in the hero SKU and a generic in the blend or the private-label range.
The specification a generic must meet to stand next to a brand
- Root only, with withaferin A reported and capped.
- Assay method named on the COA; HPLC profile available per lot.
- Heavy metals by ICP-MS as numbers; residue panel for the destination market.
- Facility certificates you can name; third-party testing on request.
- A published COA and specification, so the claim is checkable before the first call.
That list is what the SV Botanica ashwagandha page is built to answer.
