The Placenta Promise: Myth, Medicine, or Modern Risk?

The placenta, the tree of life that nourishes a baby in the womb, is now being consumed by mothers after birth. But does this ancient-looking practice hold any modern-day benefits?

Animal Instinct

Common in most mammals but historically rare in humans

Modern Trend

Typically consumed as dehydrated capsules

Scientific Scrutiny

Research fails to support most claimed benefits

Potential Risks

Documented cases of infection transmission

Introduction: From Animal Instinct to Human Trend

In the animal kingdom, from mice to monkeys, the consumption of the placenta after childbirth is almost universal. In recent decades, this practice, known as placentophagy, has quietly crossed into human culture, particularly in Western industrialized nations 3 .

Driven by celebrity endorsements and a growing interest in "natural" postpartum remedies, a small but significant number of women are now choosing to ingest their own placentas, often in the form of dehydrated capsules, in the hope of fending off depression, boosting energy, and enhancing milk production 7 9 .

Despite its popularity in certain circles, the practice remains highly controversial. There is a profound disconnect between the enthusiastic anecdotal reports from advocates and the cautious, evidence-based perspective of the scientific and medical community 1 4 .

This article delves into the heart of this controversy, separating the myths from the facts and exploring why a practice that seems so instinctual may carry hidden risks for humans.

Animal Kingdom

Placentophagy is common across mammalian species but historically rare in human societies.

95% Mammals
5% Historical Humans

What Is Placentophagy?

Placentophagy is defined as "the ingestion of a human placenta postpartum, at any time, by any person, either in raw or altered form" 7 . While almost all non-human placental mammals engage in this behavior, humans are a notable exception. Historically, there is no evidence that placentophagy has been a regular, culturally normative practice in any traditional or historic society 2 7 .

Raw Consumption

Some consume small pieces of raw placenta immediately after birth, often in smoothies.

Encapsulation

The most common method: steaming, dehydrating, and powdering the placenta into capsules.

Cooking

Some incorporate placenta into meals, similar to organ meats.

Encapsulation Process
  1. Steaming
    Placenta is steamed, sometimes with herbs
  2. Dehydration
    Sliced and dehydrated at low temperatures
  3. Powdering
    Ground into fine powder
  4. Encapsulation
    Powder placed into capsules for consumption

The Allure of the Afterbirth: Common Claims and the Scientific Reality

Proponents of placentophagy claim a host of benefits, largely centered on countering common postpartum challenges. Let's examine the most frequent assertions alongside what current scientific research reveals.

Prevents Postpartum Depression

Theory: Replenishes hormones depleted during childbirth 2 .

Science: No significant mood improvements found in clinical studies 6 .

Not Supported

Boosts Energy & Recovery

Theory: High iron and B12 content reverses anemia 1 .

Science: No positive impact on iron status; provides only ~25% of RDA 3 7 .

Not Supported

Increases Milk Production

Theory: Lactogenic hormones stimulate milk flow 3 .

Science: No demonstrated benefit; milk production driven by other mechanisms 1 .

Not Supported

Scientific Evidence Summary

Claimed Benefit Theoretical Basis Scientific Verdict
Prevents postpartum depression Replenishes depleted hormones No significant mood improvements found 6
Increases energy & reduces anemia High iron and B12 content No positive impact on maternal iron status 7
Enhances breast milk production Presence of lactogenic hormones No demonstrated benefit 1
Decreases pain & speeds healing Proposed opioid-enhancing factor (POEF) Evidence from rodents only 2 4

A Deep Dive into a Key Experiment: The Pilot RCT

To move beyond anecdotes, researchers have begun conducting controlled trials. One of the most cited is a pilot randomized controlled trial (RCT) by Young et al., which aimed to objectively test the psychological effects of placentophagy.

Methodology: A Step-by-Step Approach

  1. Recruitment & Randomization: The study enrolled 36 healthy, pregnant women who had already decided to consume their placenta. After giving birth, they were randomly assigned to one of two groups.
  2. Design: The study was double-blind, meaning neither the participants nor the researchers knew who was in which group 6 .
  3. Supplementation: Participants took their assigned capsules for three weeks postpartum 6 .
  4. Data Collection: Participants completed standardized questionnaires measuring depressive symptoms, fatigue, and maternal-infant bonding 6 .

Study Groups

Placenta Group

Received capsules containing their own dehydrated, powdered placenta

Placebo Group

Received identical capsules containing dehydrated beef

Results and Analysis

The study's results, published in 2018, were clear. The researchers found no significant differences between the placenta group and the placebo group on any of the measured psychological outcomes 6 .

Detailed Findings from the Pilot Trial

Outcome Measured Assessment Tool Key Finding
Depressive Symptoms Edinburgh Postnatal Depression Scale (EPDS) No significant difference between groups; similar trends over time 6
Fatigue Profile of Mood States (POMS) Fatigue levels decreased similarly in both groups, with no significant difference 6
Maternal Bonding Maternal Attachment Questionnaire (MAQ) No statistically significant differences in bonding scores 6

The authors concluded that their findings "do not offer strong support for the most regularly cited benefits of placentophagy" 6 . This pilot trial demonstrated that rigorous research in this area is feasible, but its preliminary results failed to validate the anecdotal claims made by placentophagy advocates.

The Unseen Risks: An Organ That Protects Can Also Contain

While the benefits remain unproven, research has identified tangible risks associated with consuming the placenta.

The Placenta is Not Sterile

Contrary to old beliefs, the placenta is not a sterile organ. It has its own bacterial culture and can contain potential bacteria and viruses 1 . Its primary function is to act as a filter, protecting the fetus from toxins and bacteria. In doing so, it can accumulate elements like mercury, lead, and other toxins 1 2 .

Potential Contaminants
  • Bacteria (including Group B Streptococcus)
  • Viruses
  • Environmental toxins (mercury, lead)
  • Medications taken during pregnancy

The Case of Group B Strep Infection

The U.S. Centers for Disease Control and Prevention (CDC) documented a case where an infant in Oregon was hospitalized for late-onset Group B Streptococcus (GBS) sepsis 1 9 .

Initial Recovery

Infant had been treated for early-onset GBS and had recovered.

Symptoms Return

GBS symptoms returned, requiring hospitalization.

Investigation

Mother was consuming placenta capsules contaminated with GBS.

Confirmation

Genetic testing confirmed identical bacteria in capsules and baby 1 .

Important: The processing of the placenta (steaming and dehydrating) was insufficient to kill the hardy bacteria 1 . This case provides a direct link between placenta consumption and a serious neonatal infection.

Research Tools for Studying Placentophagy

Research Tool Function in Placentophagy Research
Placebo Capsules Dehydrated beef or other inert substances used to create identical placebo pills for controlled trials 6
Salivary Hormone Assays Non-invasive tests that measure hormone levels to determine if placenta ingestion influences maternal hormone profiles 3
Nutritional Analysis Techniques like mass spectrometry used to quantify levels of iron, selenium, and other elements 3
Microbial Culture & DNA Sequencing Used to identify bacterial composition of placental tissue, crucial for assessing infection risks 8
Standardized Psychological Scales Validated questionnaires provide objective measures of mood, fatigue, and bonding 6

Conclusion: Weighing the Evidence

The exploration of human placentophagy presents a clear picture: the risks currently outweigh the unproven benefits.

Unproven Benefits

Robust scientific evidence has so far failed to validate claims of improved mood, energy, or lactation.

Documented Risks

Evidence of potential harm, including the risk of passing bacteria and toxins, is growing 1 4 9 .

"When it comes to eating your placenta, the risks really outweigh any perceived benefits."

Dr. Goje from the Cleveland Clinic 9

The Real Reward

After a journey of growing a new life, the focus can remain on the beautiful outcome. As Dr. Goje reminds us, "The baby is the reward, not the placenta" 9 .
