Formulating with Standardised Botanicals: A Guide for Evidence-Based Product Development

Formulating with Standardised Botanicals

As the global wellness industry continues to evolve, botanical ingredients remain foundational to supplements, functional foods, and clean-label cosmetics. Yet not all plant-based inputs offer the same value. The distinction between a generic extract and a standardised botanical is critical—not only from a scientific standpoint but for efficacy, regulatory readiness, and market integrity.

In an era where clinical reproducibility, label transparency, and global compliance are non-negotiable, standardisation is no longer an option. It is a prerequisite for credible, high-performing formulations.


What Is a Standardised Botanical Extract?


A standardised extract contains one or more active phytochemicals in a defined, quantifiable concentration, measured and verified through validated analytical techniques.

Common examples include:

  • Turmeric extract standardised to 95% curcuminoids

  • Ashwagandha extract standardised to 5% withanolides

  • Green tea extract standardised to 60% EGCG

  • Bacopa extract standardised to 50% bacosides

This approach contrasts sharply with raw powders or unstandardised extracts, where active levels may fluctuate due to factors such as climate, soil conditions, or post-harvest processing.


Why Standardisation Matters: Consistency and Control


Botanical extracts are inherently variable. Without standardisation, ensuring a consistent therapeutic dose—or achieving repeatable clinical outcomes—is nearly impossible. Active content may be affected by:

  • Geographical origin

  • Harvesting season

  • Extraction technique

  • Post-harvest handling

Standardisation addresses these variances by ensuring that each batch meets predefined specifications for potency. This enables:

  • Clinical relevance and alignment with published data

  • Precision dosing without the need for overage buffers

  • Regulatory clarity, especially in markets like the EU or Australia (TGA)

  • Consumer trust, grounded in reliable product performance


Analytical Methods: How Potency Is Measured


To validate the concentration of active compounds, reputable suppliers employ robust assay techniques. The most commonly used include:


1. HPLC (High-Performance Liquid Chromatography)


  • High precision

  • Ideal for quantifying marker compounds such as curcumin, bacosides, or withanolides

  • Required for regulatory submissions and clinical-grade products


2. TLC (Thin Layer Chromatography)


  • Moderate precision

  • Used primarily for identity confirmation and raw material authentication

  • Suitable for initial screening or low-risk botanical inputs

Additional tools like UV-Vis spectrophotometry or GC-MS may be employed depending on the compound class. However, HPLC remains the gold standard for most high-potency, regulatory-sensitive applications.

When sourcing extracts, always request:

  • Method of assay (HPLC, TLC, etc.)

  • COAs with clear marker percentages

  • Batch testing frequency

  • Confirmation that markers are naturally derived—not synthetically spiked


Advantages of Using Standardised Extracts

✅ Clinical Alignment

Many human trials reference specific standardised extracts. Aligning formulations with those specifications ensures evidence-based claims and enhances credibility.

✅ Regulatory Preparedness

Standardised actives simplify ingredient submissions under FSANZ, TGA, and other frameworks. They offer traceable data points essential for novel food and therapeutic goods applications.

✅ Global Market Viability

Retailers, manufacturers, and international partners expect documentation. Standardised botanicals support smoother logistics, faster compliance reviews, and lower regulatory risk.

✅ Optimised Dosing & Shelf Stability

Defined potency enables more accurate formulation, reduces the need for overages, and improves label integrity over time.


Case Study: Ashwagandha Extract


Two formulations may list “Ashwagandha root extract,” but only one specifies 5% withanolides by HPLC. The other might contain <1%, leading to vastly different outcomes in stress modulation, hormonal support, and customer satisfaction.

Standardised Ashwagandha ensures:

  • Reproducible cortisol-lowering effects (as demonstrated in trials)

  • Consistency in adaptogen blends

  • Alignment with claims tied to specific dosage ranges


Key Questions to Ask Suppliers


Before committing to a botanical input, ensure the supplier can clearly answer the following:

  • What is the level and type of standardisation?

  • Which assay method is used (HPLC, TLC, etc.)?

  • Is testing conducted per batch, or periodically?

  • Can up-to-date COAs and stability data be provided?

  • Are the actives naturally occurring or synthetically enhanced?

  • Is the material compliant with FSANZ, TGA, USP, or other regulatory standards?

A supplier’s transparency on these points reflects the reliability of the ingredient—and the brand’s ability to deliver a consistent consumer experience.


Conclusion: Standardisation as a Strategic Advantage

As the natural product sector continues to scale, formulating with standardised botanicals is no longer just best practice—it is foundational. From clinical efficacy and regulatory compliance to shelf-life stability and global scalability, standardised extracts enable brands to meet the demands of today’s highly informed, health-focused consumers.

The future of plant-based innovation lies in products that are not only inspired by tradition but also verified by science.
