Placentophagy's effects on mood, bonding, and fatigue: A pilot trial, part 2.

BACKGROUND: Human maternal placentophagy is gaining popularity among a growing number of women who believe it provides maternal benefits, including prevention of postpartum blues/depression, improved maternal bonding, and reduced fatigue. METHODS: We conducted a randomized, double-blind, placebo-controlled pilot study (N=27) in which participants consumed either their processed, encapsulated placenta (n=12), or similarly prepared placebo (n=15). Maternal mood, bonding, and fatigue were assessed via validated scales across four time points during late pregnancy and early postpartum. Psychometric data were analyzed for changes between and within both groups over time. RESULTS: No significant main effects related to maternal mood, bonding, or fatigue were evident between placenta and placebo group participants. However, examination of individual time points suggested that some measures had specific time-related differences between placenta and placebo groups that may warrant future exploration. Though statistical significance should not be interpreted in these cases, we did find some evidence of a decrease in depressive symptoms within the placenta group but not the placebo group, and reduced fatigue in placenta group participants at the end of the study compared to the placebo group. CONCLUSIONS: No robust differences in postpartum maternal mood, bonding, or fatigue were detected between the placenta and placebo groups. This finding may be especially important for women considering maternal placentophagy as a 'natural' (i.e., non-pharmacological) means of preventing or treating blues/depression. Given the study limitations, these findings should be interpreted as preliminary. Small, time-related improvements in maternal mood and lower fatigue post-supplementation among placenta group participants may warrant further research.

Effects of placentophagy on maternal salivary hormones: A pilot trial, part 1.

BACKGROUND: Recent studies show that human placenta, processed and encapsulated for postpartum consumption, contains a host of trace minerals and hormones that could conceivably affect maternal physiology. Our objective was to investigate whether salivary hormone concentrations of women ingesting their own encapsulated placenta during the early postpartum differed from those of women consuming a placebo. METHODS: Randomly assigned participants (N=27) were given a supplement containing either their dehydrated and homogenized placenta (n=12), or placebo (n=15). Saliva samples were collected during late pregnancy and early postpartum. Samples of participants' processed placenta, and the encapsulated placebo, were also collected. Hormone analyses were conducted on all samples utilizing liquid chromatography-tandem mass spectrometry. RESULTS: There were no significant differences in salivary hormone concentrations between the placenta and placebo groups post-supplementation that did not exist pre-supplementation. There were, however, significant dose-response relationships between the concentration of all 15 detected hormones in the placenta capsules and corresponding salivary hormone measures in placenta group participants not seen in the placebo group. The higher salivary concentrations of these hormones in the placenta group reflects the higher concentrations of these hormones in the placenta supplements, compared to the placebo. CONCLUSIONS: Some hormones in encapsulated placenta lead to small but significant differences in hormonal profiles of women taking placenta capsules compared to those taking a placebo, although these dose-response changes were not sufficient to result in significant hormonal differences between groups. Whether modest hormonal changes due to placenta supplementation are associated with therapeutic postpartum effects, however, awaits further investigation.

Presence and concentration of 17 hormones in human placenta processed for encapsulation and consumption.

Human maternal placentophagy is a rare but growing practice in several industrialized countries among postpartum mothers seeking a variety of purported health benefits attributed to the practice. These postpartum mothers typically consume their placenta as a processed, encapsulated supplement. To determine whether free (unconjugated) steroid hormones and melatonin in placenta can survive the encapsulation process (namely steaming and dehydration), we analyzed 28 placenta samples processed for encapsulation using liquid chromatography tandem-mass spectrometry (LC-MS/MS) to evaluate the concentration of 17 hormones. The results revealed detectable concentrations for 16 of the hormones analyzed, some in concentrations that could conceivably yield physiological effects.
