BUYER DECISION GUIDE
When to Select the 95% Curcumin Grade

QUALITY & DOCUMENTATION
Batch Verification for B2B Qualification
The reviewed representative COA records 95.11% curcumin by UV, 3.08% loss on drying and 2.13% 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.
Beyond “95%” — What Curcumin Buyers Should Actually Check
Application / Formulation Example: Curcumin 95% is the workhorse of joint and inflammatory-support formulas, but the “95%” figure alone doesn’t tell the whole story. The two numbers that matter: curcuminoid content (95%) and the curcumin:demethoxycurcumin:bisdemethoxycurcumin ratio (typically ~77:17:6 in natural turmeric). For bioavailability, standard practice pairs 500 mg curcumin 95% with 5–10 mg piperine, or uses a patented bioavailable form (phytosome/lipid-based) where the brand claims enhanced absorption.
Spec Comparison:
| Parameter | Our Curcumin 95% | Low-Grade “Curcumin” (70–80%) | Unstandardized Turmeric Powder |
|---|---|---|---|
| Curcuminoids | ≥95% (COA) | 70–80% | 2–5% |
| Curcumin ratio | Documented (77:17:6-type) | Often undocumented | N/A |
| Extraction | Controlled solvent, residual tested | Varies | Raw spice |
| Application | Nutraceutical dose-efficient | Compromised dosing | Culinary only |
Market Context: Turmeric/curcumin is one of the largest botanical extract categories globally, with demand sustained across joint, metabolic, and cognitive health. In a mature category, the differentiation shifts to documented ratios, batch-level COA, and application-ready formats. (Qualitative trend.)
