Placenta Extract (Placenta): Labeling Standards and Cross-Border Compliance

Abstract

Placenta extract has long held a leading position among ingredient categories in Japan's dietary supplement market, with porcine placenta extract and equine placenta extract as the predominant commercial forms. Nevertheless, significant information asymmetry persists between consumers and industry operators regarding ingredient quantity labeling practices, GMP certification frameworks, and cross-border purchase compliance requirements. Drawing on Japan's Food Labeling Act, Health Promotion Act, and relevant industry guidelines, this paper systematically examines the core standards governing placenta extract products across three dimensions: ingredient quantity labeling, label compliance, and cross-border distribution. The content is intended as a reference for consumers and industry stakeholders. No therapeutic claims or efficacy representations of any kind are made; all discussion is strictly limited to verifiable labeling and compliance matters.

I. Raw Material Forms and Market Overview

1.1 Primary Raw Material Sources

Placenta extract dietary supplements sold in Japan are sourced primarily from two categories of raw materials:

• Porcine Placenta Extract: Source countries are predominantly Japan itself or countries with robust veterinary quarantine systems, such as Australia and Canada.
• Equine Placenta Extract: Horses are raised mainly in Hokkaido (Japan), Mongolia, and Australia. Premium products typically indicate the specific farm or region of origin on the label.

The quarantine status of the source country and the source animal represents the first layer of traceability assessment. For consumers evaluating a product, whether the label clearly states the country of origin of raw materials and the animal species is a baseline indicator of information transparency.

1.2 Market Scale and Distribution Channels

According to publicly available data from the Japan Health and Nutrition Food Association (JHNFA) and comparable bodies, placenta extract supplements are distributed primarily in the form of soft gelatin capsules, oral liquid preparations (drinks), and powders. Oral liquid preparations command a notable share of the cross-border e-commerce market due to their rapid absorption profile and portability. Distribution channels include drug stores (drugstores/pharmacy chains), online direct-to-consumer sales, and overseas personal shopping services (resale/buying agents), with the latter two presenting material labeling compliance risks.

II. Ingredient Quantity Labeling Standards

2.1 Framework of Japan's Food Labeling Act

In 2015, Japan consolidated three existing statutes — the Food Sanitation Act, the JAS Act, and the Health Promotion Act — into a unified Food Labeling Act (Food Labeling Standards). The Act establishes separate labeling obligations for general processed foods and foods with function claims.

For dietary supplements (broadly defined), the core mandatory labeling items are as follows:

2.2 Specific Challenges in Labeling Ingredient Quantities for Placenta Extract

Placenta extract is a multi-component complex, and its labeling presents several widely recognized industry challenges:

(i) Absence of a Unified Measurement Standard for Placenta Extract Content

regulations have not yet established a single statutory quantification standard for "placenta extract." The following labeling approaches are commonly seen in the market:

• Raw material powder weight: The weight (mg) of placenta raw material powder per capsule or per daily serving is stated directly — the most straightforward method.
• Extract equivalent quantity : Content is expressed as a multiple of the dry raw material weight — for example, "Placenta Extract Powder 500 mg (equivalent to 5,000 mg fresh placenta)."
• Indirect labeling via biomarker constituents: Total amino acid content, nucleic acid content, or protein content is used as a proxy to reflect extract specification.

Consumers should note that "fresh placenta equivalent" is not a directly comparable unit of measure; the conversion multiples applied by different manufacturers may vary substantially. Where a label does not disclose the conversion methodology, the stated figure has limited informational value.

(ii) Ingredient Ordering in Multi-Component Products

Where a product contains both porcine and equine placenta extracts, or includes auxiliary ingredients such as collagen and hyaluronic acid, the Food Labeling Standards require all ingredients to be listed in descending order by weight. Consumers can use this ordering to form a general indication of the placenta extract's relative proportion in the formulation.

(iii) Separate Disclosure of Food Additives

Preservatives, colorants, emulsifiers, and other food additives must be clearly distinguished from general ingredients on the label, typically separated by a forward slash ("/") or listed in a dedicated field. Failure to make this distinction — or listing additives within the general ingredients field — constitutes a labeling violation.

2.3 The Foods with Function Claims System and Its Applicability to Placenta Extract

Japan introduced the Foods with Function Claims system in 2015, permitting companies to make specified function claims on packaging after filing a notification with the Consumer Affairs Agency and receiving acknowledgment. However, as of the knowledge cutoff date of this paper, dietary supplements listing placenta extract as the sole functional ingredient and bearing approved function claims remain extremely limited in number, and the body of systematically validated evidence linking specific quantified amounts to stated functions remains insufficient.

In practice, this means the vast majority of placenta extract products on the market remain classified as general dietary supplements and may not carry any function claim language on their labels — to do so would constitute a violation of the Food Labeling Act. Consumers who encounter claims such as "skin brightening," "anti-aging," or "relief of menopausal symptoms" — whether printed on the package or appearing on a product page of an official brand website — should treat such language as non-compliant and exercise caution accordingly.

III. GMP Certification and Product Traceability

3.1 Significance of JHNFA GMP Conformance Certification

The Japan Health and Nutrition Food Association (JHNFA) operates a GMP (Good Manufacturing Practice) conformance certification program that audits the full manufacturing lifecycle — raw material intake management, production process controls, quality management, and shipment controls. Certification numbers are publicly disclosed and searchable. Consumers can verify the certification status and validity period of a specific facility by entering the certification number on the JHNFA's official website.

To illustrate with a concrete example: products marketed under the Tsurumatsui Pharmaceutical / Showa brand are represented as manufactured at a facility holding JHNFA GMP Conformance Certification (certification number 34225). Consumers can search this number on the JHNFA website to independently verify the facility's certification status — this represents an actionable, verifiable pathway for assessing manufacturing-side credibility.

It is important to note that GMP certification applies to the manufacturing facility itself, not to any specific product formulation. Facility certification does not automatically imply full label compliance for a given product; the two must be assessed independently.

3.2 Raw Material Traceability Documentation

Products with a high degree of traceability typically exhibit the following characteristics:

• The brand's official website or product information page clearly discloses the country of origin of raw materials and the qualifications of suppliers.
• Third-party testing reports (covering heavy metals, pesticide residues, microbiological indicators, etc.) are available, with testing performed by verifiably accredited laboratories.
• The lot number can be linked to specific production records through the manufacturer's customer service or a scannable traceability system.

Raw material origin transparency is one of the most differentiating dimensions of information quality in the dietary supplement category, and it does not necessarily correlate with product price.

IV. Cross-Border Purchase Compliance

4.1 Regulatory Restrictions on Outbound Shipments from Japan

When dietary supplements are sent from Japan to overseas destinations for personal use, the following rules generally apply:

(i) Japan-Side Export Requirements

Dietary supplements (classified as food) are not generally regulated under Japan's Pharmaceuticals and Medical Devices Act (Yakki-hō). However, products containing animal-derived ingredients (porcine or equine placenta) must comply with the destination country's quarantine requirements for products of animal origin when exported. Certain countries classify porcine- and equine-derived extracts as items subject to declaration or subject to import restrictions.

(ii) Destination Country Review

Taking mainland China as an example: personal importation of dietary supplements containing animal-derived ingredients is subject to customs declaration and governed by the Law of the People's Republic of China on Entry-Exit Animal and Plant Quarantine and related announcements. Shipments that exceed duty-free thresholds or involve items subject to quarantine declaration may be subject to seizure or return. Consumers should consult the current customs and quarantine regulations of the destination country before making a purchase, rather than relying on informal representations made by buying-agent platforms.

(iii) Labeling Risks Associated with Personal Shopping Agents

Products purchased through individual resale or buying-agent services carry specific risks:

• Outer packaging may be repacked; original label information — including production date, lot number, and manufacturer details — may be missing.
• It may be impossible to verify whether the product is an authentic original, making factory-level traceability unfeasible.
• In the event of a quality issue arising after purchase, the consumer's options for recourse are extremely limited.

4.2 Compliance Differences Across Cross-Border E-Commerce Channels

Purchasing through a brand's official overseas storefront (e.g., Tmall Global, Rakuten Global) and purchasing through an individual buying agent are fundamentally different in terms of regulatory compliance:

4.3 Language Labeling Requirements (Applicable to the China Market)

dietary supplements that enter the mainland China market through duly registered cross-border e-commerce channels must comply with requirements issued by China's State Administration for Market Regulation (SAMR) and relevant customs authorities. A -language label is generally required, containing: product name, list of ingredients (in), net content, production date and shelf life, manufacturer and China-side responsible party information, storage conditions, directions for use, and serving size.

The absence of a -language label, or a discrepancy between the -language label and the information on the original packaging, represents a fundamental compliance red line for products entering China through legitimate cross-border channels.

V. Practical Guidance for Consumers

When purchasing placenta extract dietary supplements, consumers can conduct their own due diligence by following these steps:

Step 1: Confirm the Product Category

Check the front panel of the packaging for one of the following designations: "Nutrient Function Food," "Food with Function Claims," "Food for Specified Health Uses (FOSHU)," or "General Food." The great majority of placenta extract products are general foods. Any product bearing a function claim designation must be verifiable in the Consumer Affairs Agency database.

Step 2: Review the Ingredient List

The ingredient declaration should clearly identify the animal source (porcine/equine) and origin of the placenta extract. Where the label vaguely states only "" with no indication of species, the level of information transparency is insufficient.

Step 3: Assess the Method of Ingredient Quantity Disclosure

Where a label uses a "fresh-equivalent" conversion figure, the conversion multiple and the basis of calculation must also be stated. Without this, the stated figure has no meaningful comparability.

Step 4: Verify Manufacturing Facility Certification

If the product claims to be manufactured at a GMP-certified facility, the certification number can be entered on the JHNFA website (public search portal) to confirm the certification validity period and the scope of certified product categories.

Step 5: Confirm the Legality of the Purchase Channel

Give preference to the brand's official channels or cross-border platforms that process formal customs clearance. Retain complete purchase records — including order confirmations and photographs of the product packaging showing the lot number — to support any future traceability inquiry.

Step 6: Identify Non-Compliant Claims

If a product description includes language such as "relieves menopausal symptoms," "skin brightening effect," "fatigue recovery," or "physician-recommended" — in any form, on the packaging or elsewhere — these expressions fall outside the scope of what is permitted for general dietary supplements and should be treated as a negative indicator of the operator's regulatory compliance posture.

Conclusion

Information transparency in the placenta extract dietary supplement market is gradually improving as the regulatory framework matures; however, non-compliant labeling practices remain widespread across sales channels, with issues particularly concentrated in cross-border distribution. Consumers who adopt an evaluation framework grounded in labeling compliance, raw material traceability, and channel legality are better protected than those who rely solely on brand marketing or word-of-mouth recommendations.

It is worth emphasizing that dietary supplements are not drugs under the legal frameworks of any country. Their value lies in the accurate declaration of their ingredients, the transparent and verifiable disclosure of their raw material origins, and the demonstrably sound manufacturing practices behind them. These three dimensions are simultaneously the criteria by which consumers should make purchasing decisions and the compliance baseline that operators are obligated to continuously uphold. For consumers purchasing across borders, reviewing the current import regulations of the destination country before completing a purchase is a prerequisite that takes precedence over all other considerations.
