What Is Turmeric Extract 95%?

Turmeric extract 95% refers to a concentrated extract from turmeric rhizomes that has been standardized to contain at least 95% total curcuminoids.

The key distinction:

  • Turmeric powder: Contains 2-7% curcuminoids naturally
  • Turmeric extract 95%: Concentrated to ≥95% curcuminoids

This 15-40x concentration makes turmeric extract the preferred form for therapeutic applications where curcumin dosage matters.

Understanding Curcuminoids

“Curcuminoids” is a collective term for three closely related compounds found in turmeric:

1. Curcumin (Diferuloylmethane)

The primary curcuminoid. Represents 75-80% of total curcuminoids in typical extracts.

Structure: Two ferulic acid molecules linked by a methylene group

Properties:

  • Bright yellow-orange color
  • Fat-soluble
  • Unstable in alkaline conditions
  • Primary compound studied for health benefits

2. Demethoxycurcumin (DMC)

The second most abundant curcuminoid. Represents 15-20% of total curcuminoids.

Structure: Similar to curcumin but with one methoxy group removed

Properties:

  • Slightly different bioactivity profile
  • May have superior antioxidant activity in some assays
  • Often considered alongside curcumin in research

3. Bisdemethoxycurcumin (BDMC)

The least abundant curcuminoid. Represents 3-5% of total curcuminoids.

Structure: Curcumin with both methoxy groups removed

Properties:

  • Most stable of the three curcuminoids
  • Different pharmacokinetic profile
  • Included in total curcuminoid calculations

Typical Composition of 95% Extract

A standard turmeric extract 95% curcuminoids typically contains:

ComponentTypical RangeSpecification
Total curcuminoids95-98%≥95%
Curcumin70-80%Typically ≥75%
DMC15-25%Balance
BDMC2-5%Balance
Volatile oils<1%Residual
Other compounds2-5%Matrix/carrier

Why 95%?

The 95% standardization has become industry standard because:

  • High enough concentration for therapeutic dosing
  • Economically viable to produce at scale
  • Establishes consistent baseline for research comparison
  • Regulatory familiarity in major markets

Higher concentrations (98%+) exist but are more expensive and may not offer proportional benefits.

Production Methods

Solvent Extraction

The most common method. Turmeric is extracted using food-grade solvents.

Process:

  1. Dried turmeric is ground to appropriate particle size
  2. Extracted with solvent (ethanol, acetone, or ethyl acetate)
  3. Solvent removed by evaporation
  4. Crude oleoresin purified through crystallization
  5. Product dried and standardized

Advantages:

  • Efficient extraction
  • High yields
  • Scalable production
  • Well-established process

Considerations:

  • Residual solvent limits must be met
  • Environmental handling of solvents required
  • Some consumers prefer solvent-free options

Supercritical CO2 Extraction

Premium extraction method using carbon dioxide.

Process:

  1. CO2 pressurized to supercritical state
  2. Passes through turmeric material
  3. Extracts curcuminoids and oils
  4. Pressure reduced, CO2 returns to gas
  5. Extract collected, further purified

Advantages:

  • No residual solvents
  • “Green” extraction method
  • Preserves volatile compounds
  • Clean label appeal

Considerations:

  • Higher equipment cost
  • Lower throughput than solvent
  • May require additional purification for 95%+

Hybrid Methods

Some manufacturers use combinations:

  • Initial CO2 extraction for oleoresin
  • Solvent purification for curcuminoid concentration
  • Final crystallization for 95%+ purity

  • Purification steps
  1. “Can you provide a full COA?”
  • All parameters in specifications table
  • From accredited laboratory
  • Batch-specific, not generic
  1. “What’s your lead specification?”
  • Lead is critical concern
  • <1 ppm for supplements
  • <0.5 ppm for premium/California
  1. “What’s your residual solvent profile?”
  • If solvent-extracted
  • All Class 2/3 solvents tested
  • Within ICH limits
  1. “Do you have stability data?”
  • Accelerated and real-time
  • Per ICH guidelines
  • For specific storage conditions
  1. “Is the facility GMP certified?”
  • For pharmaceutical: cGMP required
  • For supplements: GMP preferred
  • Audit reports available?

Red Flags

  • Curcumin content claims that seem too good (>98% at commodity prices)
  • Inability to provide batch-specific COAs
  • No heavy metal testing
  • No residual solvent data (for solvent-extracted)
  • Significantly below-market pricing
  • Generic certificates without batch numbers

Sample Protocol

  1. Request samples with full COA
  2. Send to third-party lab for verification
  3. Test key parameters: curcuminoids, heavy metals, microbiological
  4. Compare COA claims to third-party results
  5. If claims match, proceed with qualification
