Though the majority of evidence out there is based on personal observation, there is been so much positive feedback about placenta consumption! There have been reports of a more balanced mood, increased energy levels, better sleep, restoration of iron levels, and increased milk supply.There has been some scientific evidence that suggests that hormones remain present in the placenta. Researchers have found that progesterone and estradiol remain at high enough levels to cause physiological effects if consumed. No large randomized study exists that suggests that there are any serious risks associated with placenta consumption. A very small number of people did report a feeling of jitteriness and an increase in anxiety feeling very similar to being over caffeinated. in fact, it is recoomended that if you have a sensitivity to caffine, placenta consumption might not be a good fit for you. There have also been a small number of people that have reported a decrease in supply after ingesting the capsules, but, without a large randomized study, it is difficult to say whether or not this was actually caused by the consumption of the placenta or just the natural variation in breastfeeding experiences. The CDC currently warns against placenta encapsulation, but again, there is very little evidence to support this recommendation without a large randomized study.
