Harvard’s Take On Bioidentical Hormones

Bioidentical hormones are not a huge global debate unlike other medicines or procedures, but there controversies and debates still revolve around it. It’s not all that surprising when you ask people about it and they end up clueless. Women and other health experts have difficulties with the change in opinions towards the entire hormonal therapy; which began when WHI or the Women’s Health Initiative conducted trials where estrogen and progestin proved to prevent illness that are common with age. Unfortunately, it was put to a clear stop back in 2002 since a handful of hormone users were more prone to breast cancer, blood clots, heart disease and stroke. Even though the risks were not all that alarming, the trials were shut down.


Searching for ‘natural’ hormones

People often assume that just because something is dubbed ‘natural’ that it’s probably safer and better but in truth ‘natural’ is open to a wide variations of interpretations. A product is considered natural when its main ingredients are from animals, mineral resource or plants; this applies regardless of the product’s form. A good example would be when the soy plant becomes the star ingredients of supplements that women take in order to ease their menopausal symptoms. Here’s the catch, soy supplements were never rally regulated and have not been thoroughly tested in humans so we have no idea if they’re effective or if they work at all.

Bioidential Hormones


The want for an effective and natural approach to research therapy has paved the way for bioidentical hormones; these are hormones that are highly identical, in terms of molecular structure, to the hormones produced in a woman’s body. Bioidential hormones are not found in nature but they are created from soy and yams.

Bioidentical hormone therapy is also called ‘natural hormone therapy’ since the bioidentical hormones used on someone acts like the hormones that the body naturally produces. Technically speaking, the human body can’t identify a bioidentical hormone from a hormone produced by the ovary itself. In any blood test, the natural estradiol will determine the total amount of bioidentical estradiol that you’ve taken as well as how much was actually produced by the body. Meanwhile, Premarin is metabolized into varying forms of estrogen which can’t be measured by laboratory tests. The people who believe in the advantages of bioidentical hormones say that it can be measured more accurately compared to premarin.
