What is Physta®? Standardization, COA, and Tongkat Ali

Quick facts about Physta®

The information above comes from the analysis certificate for batch TA 2506105.
Therefore, batch-specific values and dates apply only to that particular production batch.
They should not automatically be transferred to future batches.

What is Physta®?

Physta® is the name of a specific extract and not of the plant species itself. Tongkat Ali is the common name for Eurycoma longifolia, while Physta® denotes a trademarked raw material that the manufacturer produces from the plant’s root.

Biotropics Malaysia describes Physta® as a proprietary, water-soluble, and standardized
extract from Malaysian Eurycoma longifolia root. In addition, the company states that the product
complies with the Malaysian standard MS 2409:2011.

This information comes from

the manufacturer’s technical presentation of Physta®.
The information should therefore be understood as manufacturer information.

Therefore, the distinction between the plant name and the product name is important. A study, specification,
or analysis that applies to Physta® does not automatically apply to ordinary Tongkat Ali powder or
another extract. At the same time, an analysis of a specific batch only describes the
production batch to which the document is linked.

How does water extraction work?

During water extraction, the producer uses water to transfer water-soluble components
from the root material to an extract solution. The water is then removed, and the extract is converted
into powder. The manufacturer also describes Physta® as a freeze-dried water extract.

However, the process differs from simple grinding. When a producer manufactures root powder, the dried root is ground,
and both soluble and insoluble parts of the plant material are included.
During extraction, the solvent instead affects which components are transferred to
the extract. Therefore, the extract may have a different chemical profile than the original root powder.

Furthermore, Biotropics refers to patents for parts of its extraction technology. A US
patent describes, among other things, a water extract from Eurycoma longifolia root and
specifies glycosaponins and peptide fractions as parts of the extract’s composition.

At the same time, patents describe technical solutions and claims to rights. They do not, therefore,
in themselves serve as independent proof of medical efficacy or regulatory approval.

What does standardization of Physta® mean?

First, the producer establishes specifications for selected properties. Then, each production batch
is checked against these limits. The goal is therefore to create more comparable
analysis values between different batches.

However, standardization does not automatically mean that an extract is stronger, safer, or
better than all other raw materials. In addition, one needs to know which markers are analyzed,
which ranges are used, which analysis method the laboratory applies, and whether the documentation
applies to the correct batch.

For Physta®, several analysis parameters are used instead of just one marker content.
For example, the manufacturer highlights eurycomanone, total protein fraction, total polysaccharide content,
and glycosaponins. The current analysis certificate for Aromexperten’s batch also reports
the same four groups.

Which substances and analytical markers are standardized in Physta®?

Eurycomanone

For example, eurycomanone is a quassinoid often used as a chemical marker for
Eurycoma longifolia extract. The laboratory can therefore use the marker to
check that the content is within the product’s specification. However, eurycomanone
does not describe the entire extract’s composition.

Total protein fraction

Furthermore, the analysis certificate reports total protein as a separate parameter. The term indicates
an aggregate analysis value and does not identify every single protein or every peptide.
Therefore, total protein should not be equated with a complete molecular mapping.

Total polysaccharide content

Similarly, the laboratory reports polysaccharides as a total content. The value summarizes
the result from the chosen analysis method. Here too, one must therefore distinguish between a
total value and the identification of individual molecules.

Glycosaponins

Finally, glycosaponins constitute another standardization parameter in the documentation.
The analysis shows whether the batch meets the specified minimum content. However, the value alone
does not say anything about the product’s complete chemical profile, presence of impurities, or
regulatory status.

What does a Certificate of Analysis, COA, show?

In other words, a batch-specific Certificate of Analysis shows how a single
production batch relates to the product’s defined specifications.
Below, Aromexperten’s current batch TA 2506105 is therefore used as a concrete example.

Aromexperten has published a

Certificate of Analysis for batch TA 2506105
.
The certificate states a manufacturing date of June 30, 2025, and an expiry date of June 29, 2028.
In addition, the document specifies Malaysia as the country of origin, root as the plant part used, and water as the
extraction method.

In addition, the certificate reports heavy metals. The results are stated as lead below 1.00 ppm,
mercury below 0.05 ppm, arsenic below 1.00 ppm, and cadmium below 0.20 ppm.
The asterisk in the document indicates that the laboratory did not detect the substance above the specified
reporting level.

Furthermore, the certificate reports microbiological parameters. Total aerobic count, yeast,
and mold are below 10 cfu/g. The document also indicates the absence of Salmonella,
Escherichia coli, and Staphylococcus aureus in the sample quantities described by the
specification.

Finally, the current batch and product information are also available on the page for

Physta® compared to root powder and ratio extracts

Therefore, the table shows why a high ratio, for example 100:1, does not automatically provide more
useful information than a clear specification. The ratio indication normally describes the
relationship between original raw material and extract. However, it does not necessarily
identify markers, analysis methods, or purity data.

How is Physta® used in research?

Researchers have used Physta® in several human studies. For example, a randomized,
double-blind, placebo-controlled study from 2021 investigated a standardized water extract named
Physta® in 105 men aged 50–70 over twelve weeks.

The study reports both product name, study design, and groups. Therefore, the raw material identity
becomes clearer than in research that only describes the material as “Tongkat Ali extract”.
Read the study in

Food & Nutrition Research
.

In addition, an older randomized study describes Physta® as a freeze-dried water extract
and reports the product’s use during a specific trial period. The study is openly
available via

PubMed Central
.

Overall, these studies primarily show why product identity is important.
Results from Physta® do not automatically apply to root powder, other standardizations, or
products of unknown origin.

Furthermore, when evaluating research, one needs to examine participant numbers, study duration,
primary outcomes, statistical analysis, funding, and potential conflicts of interest.

This article, however, does not review health effects in detail. The purpose is instead to
explain what Physta® is as a defined raw material and why correct product identity plays
a role when interpreting research.

Does standardization mean that Physta® is approved as food in the EU?

No. However, technical standardization, patents, and published studies do not automatically
imply EU approval as food.

In 2021, EFSA assessed a standardized water extract from
Eurycoma longifolia root as a novel food. The panel considered that the data did not
establish the safety for the proposed use.

Therefore, one needs to distinguish between the product’s technical specification and its regulatory
status. Read EFSA’s full opinion:

.

Aromexperten therefore presents Physta® as an ethnobotanical raw material, not as food,
dietary supplement, medicine, or animal feed. The product is not intended for consumption.

How to assess the documentation for a Physta® extract

First, the document should be matched against the actual product. A general datasheet can provide
relevant background, but a batch-specific COA provides more direct information about the current
raw material.

• First: Check that the document states the product name Physta®.
• Then: Match the batch number against the product’s label or delivery documents.
• Next: Check the manufacturing date and expiry date.
• Additionally: Confirm botanical name, plant part, and country of origin.
• Furthermore: Check that the document specifies water as the extraction method.
• At the same time: Compare each marker content with its specification.
• Then: Review results for moisture content, heavy metals, and microorganisms.
• Furthermore: Read footnotes, reporting limits, and disclaimers.
• Finally: Check who issued the document and when it was signed.
• Also, request an explanation if results, method, or sampling are missing.

Above all, quality should not be assessed based solely on eurycomanone or a high
extract ratio. A more complete assessment instead combines identity, process,
analytical markers, physical values, microbiology, heavy metals, traceability, and the origin of the
documents.

Summary: What is Physta®?

In summary, Physta® is a standardized water extract from Malaysian
Eurycoma longifolia root. The product name describes a specific extract and should
therefore not be used as a synonym for all Tongkat Ali material.

For batch TA 2506105, the analysis certificate reports, among other things, 0.87% eurycomanone,
35.4% total protein, 37.5% total polysaccharide, and 51.1% glycosaponin.
In addition, the document reports moisture content, particle size, heavy metals, and microbiological
values.

Standardization improves the ability to compare batches. However, it does not replace
critical review. Therefore, always check product identity, batch number, specifications,
analysis methods, the origin of the documents, and the product’s intended use.

Frequently Asked Questions about Physta®

What is Physta®?

Physta® is a trademarked and standardized water extract from the root of
Eurycoma longifolia, the plant often called Tongkat Ali.

Is Physta® the same as Tongkat Ali?

No. Tongkat Ali is a name for the plant, while Physta® is the name of a specific extract
from the plant’s root.

Which extraction method is used?

The producer uses water extraction. In addition, the analysis certificate for batch
TA 2506105 explicitly states water as the extraction method.

Which markers does the analysis certificate check?

The certificate reports eurycomanone, total protein, total polysaccharide, and glycosaponin.
In addition, it reports moisture content, heavy metals, and microbiological parameters, among others.

What does 0.87% eurycomanone mean?

The result means that the analysis for batch TA 2506105 reported 0.87% eurycomanone.
This places the value within the certificate’s specification of 0.8–1.5%.
