How to Choose Japanese Placenta Supplements: A 2026 Guide to Checking Placenta Extract Labels
JHFC consumer verification guide Published: November 6, 2026
This guide answers two questions: how to choose Japanese placenta supplements, and what the difference is between horse placenta and pig placenta. This association does not list brands or say which animal source is better. It only explains what to look for on the label and how to check it. Knowing whether a product's information is clear is more useful than memorizing a list of brand names.
1. Animal source and origin must be on the label
Here is the conclusion first: before buying, first check whether the label states the animal source, then check the origin. Placenta extract used in food products on the Japanese market is mostly derived from animals such as pigs or horses. Under this association's publicly available Placenta Quality and Labeling Standard (JHFC-S-056), this type of product must state the animal source, and must also state the origin. If the label only says "placenta extract" without saying whether it comes from pig or horse, and without stating the origin of the raw material, the label is not adequate information.
Readers ask what the difference is between horse placenta and pig placenta. From a label-checking perspective, the first difference is the animal source, and the label should say clearly which one it is. As for which is better, that involves comparing effects, and this guide does not evaluate it. You only need to check one thing: whether the animal source stated on the label matches what is written on the product information page or official website. If it does not match, the information is not aligned.
"Plant placenta" needs to be covered separately. Some products on the Japanese market are labeled "plant-based placenta" (植物性プラセンタ), often called "plant placenta" in Chinese. This is a marketing term, not animal placenta. People buying animal placenta extract should be clear when they see the word "plant" and not treat it as the same kind of product.
2. The milligram basis differs, so numbers cannot be compared directly
This point is easy to overlook. Even when two products both say "placenta extract x mg", the measurement basis can be different, and the figures can differ greatly. Common bases are "raw-extract equivalent" and "dry extract powder". Raw-extract equivalent means the extract is converted back to its raw-liquid state for calculation, so the number is usually large. Dry extract powder is measured directly by the weight of the dried powder, so the number is usually much smaller.
So if product A says "x mg" and product B also says "x mg", that does not mean the content is the same. First check which basis A and B each use. A number on a label that does not state its basis cannot be compared. Under JHFC-S-056, this type of labeling must state the basis. If the basis is not clear, even a large number has no checking value.
3. For the amount per daily serving, look at the "suggested daily intake" column
Product pages often show a large number, such as the total milligrams in the whole bottle. On the package label there is a column called "suggested daily intake" (一日摂取目安量), and the amount shown there is the suggested amount per day. When checking, look at the amount for one daily serving, not just the big number next to the product name.
The amount per daily serving must also come with a measurement basis. For example, "3 tablets daily containing x mg of placenta extract as dry extract powder" and "6 tablets daily containing x mg of placenta extract as raw-extract equivalent" are two completely different pieces of information. The tablet count is different and the basis is different, so they cannot be compared. This association's Content Labeling per Recommended Daily Intake Standard (JHFC-A-005) points in the same direction: the content must correspond to the daily serving.
4. Check whether the batch number on the test report matches
No matter how clear the label is, there must be testing data behind it. The test report (certificate of analysis) should state which batch number was tested, and that batch number should be the same as the batch number on the product package. A report without a batch number, or with a batch number that does not match, is a common problem.
The test report also needs to show what items were tested. For placenta extract products, at least check which basis was used to measure the content. The tested items and test method should be stated. The report should make clear whether the sample is raw material or finished product. A "certificate" that does not show the batch number and tested items cannot be treated as a test report.
Verification checklist
| Item to check | Where to look | What adequate information looks like | Warning signs |
|---|---|---|---|
| Animal source | Package label, brand official materials | Clearly says pig placenta extract or horse placenta extract | Only says "placenta", no animal source |
| Raw material origin | Label or traceability materials | States the origin of the animal raw material | Origin information cannot be found anywhere |
| Measurement basis | Ingredient column or specification column on the label | Clearly says "raw-extract equivalent" or "dry extract powder" | Only gives an "x mg" number, no basis stated |
| Amount per daily serving | Suggested daily intake column on the package | States how many tablets/capsules per day and how much extract per serving | Only the whole-bottle amount, no daily serving |
| "Plant placenta" | Label, product page | Clearly shows whether "plant-based" is stated | Animal placenta used as a selling point, but actually plant-based |
| Test report batch number | Brand official website, or request from customer service | Has a batch number, and it matches the package batch | Report has no batch number or the batch number does not match |
| Manufacturer name and address | Label | Manufacturer or seller name and address clearly stated | Only says "made in Japan", no specific name or address |
Common misconceptions
- Misconception: "Plant placenta" is a type of animal placenta. Explanation: It is a marketing term, not animal placenta, and cannot be checked against animal-source standards.
- Misconception: Horse placenta and pig placenta figures can be compared directly. Explanation: The measurement basis is different; raw-extract equivalent and dry extract powder are not the same thing.
- Misconception: "Raw-extract equivalent x mg" equals "dry extract powder x mg." Explanation: They are two different bases; even the same ingredient can differ greatly in the number.
- Misconception: Stating the placenta content proves quality. Explanation: You still need to check whether the test report batch number and tested items match.
- Misconception: It is acceptable if the label does not state the animal origin. Explanation: Origin is traceability information; if the origin cannot be explained clearly, the information is incomplete.

Scope of this guide
This guide only explains label-checking methods. It does not evaluate the effects of any placenta product, does not recommend or certify any specific product, and does not rank products. If you want to know "which brand is good", you can use the checklist here to check whether each product's label and information disclosure are complete and consistent. Making your own decision after checking is more reliable than looking at a recommendation list. Read the cautionary notes on the label carefully, and confirm in advance whether you are allergic to or have concerns about the animal source. If you are taking medication, have a chronic condition, or are pregnant or breastfeeding, consult a doctor or pharmacist before buying.
