I'm part way through a huge book by Jonathan Wright and Lane Lenoard on bio identical hormones and it's a real eye opener. Whilst the big drug companies have the huge budgets to push the sale of horse hormones, they have very little interest in bio-identicals because they can't patent them. That said, despite the lack of the multi million pound spends, this hasn't stopped the research, a lot of which has been carried out in Europe where the use of bios is much more widespread. There are a wealth of studies that also investigate the role of progesterone on our bodies, and the benefits this has on insomnia, depression, oestrogen related blood clots and bone density to name just a few. (Check out the PEPI study of 875 women, which used saw gains in bone density against a placebo group when progesterone or even progestin was used).
Until recently I have been using the Mirena coil which includes a progestin. I didn't realise I was peri menopausal, I've had no flushes, moods, depression or a host of other side effects I'd normally expect. The hormone on the coil is meant to last 5 years, I had mine if for much longer than this and in the last year I've started to experience insomnia and forgetfulness. I have no idea if there's any link at all between the declining amount of progestin and these effects but am hoping to check this shortly with bio-identical HRT. Let's see.
I'm not sure why something synthetic can be seen as better than something natural, in effect both bio and non bio HRT have their roots in natural substances - one in plants, the other in horse pee. The difference is the molecular structure of the bio-identical is identical to our own hormones, the latter isn't. (No great surprise unless any of us have equine roots

).
There is so much conflicting information on HRT and indeed so many GPs who are misinformed or simply spout the latest PR blurb from expensive drug companies. Personal experience is probably the most reliable route, and finding something that agrees with your body. Unfortunately we're unable to gauge longer term risks on this, but we do know what does and doesn't make us feel more like our usual selves.
