I’m not sure that GPS can prescribe bio identical hormones - as these are specially formulated in terms of strength etc for each individual - however all GPS are now supposed to offer synthetic HRT to any women that needs it (in line with recent NHS guidance). Note that the proponents of bio identical HRT say that this if you are going to take hormone supplements it is better to take ones that mimic your natural hormones than synthetic ones! There is research to support the case for and against on both sides. I personally have found that taking natural progesterone has helped me through the oestrogen spikes that I am getting as part of the peri menopause. Natural progesterone has very little side effect (other than tiredness and lethargy if you take too much) whereas oestrogen (natural or synthetic) is linked to problems with breast, uterus etc. As you can see i’ve Become a bit of an expert in all this!!
