To add to what's already been explained by sheila99.
So as sheila99 says Cyclogest is also bio-identical but it's not licensed as part of HRT. Ditto Lutigest. The ony licensed bio-identical progesterone is utrogestan

Cyclogest and utrogestan are not bio identical, they are body identical.
Cyclogest and Utrogestan are indeed bio-identical! They are also body-identical. The meaning is exactly the same.
Both the terms "bio-identical" and "body-identical" mean the hormones (in the product) are chemically identical to those your body produces.
"Bioidentical" - is the correct scientific/medical term
"Body-identical" - is more of a lay-person's, or colloquial term to explain to women who may be (understandably) confused by the terminology and the perplexing array of treatments available.
These terms refer to the hormones themselves.
So my answer to Booblet's question which was:"Can anybody suggest a bio- identical Progesterone" was completely correct.
Turning to HRT - there is much confusion about terminology with the term "bioidentical HRT" being used to describe privately (and very expensively) prescribed and unregulated COMPOUNDED bio-identical (= "body-identical") hormones, but in recent years these same "bioidentical" (="body-identical") hormones have become widely available through licensed HRT products on NHS.
The British Menopause Society distinguishes very clearly between the two different types of HRT as follows:
"
Summary of key terminologies
cBHRT: Compounded Bioidentical Hormone Replacement Therapy: Precise duplicates of human hormones which are produced by specialist pharmacies and do not follow the same MHRA regulatory pathway as conventional rBHRT
rBHRT: Regulated Bioidentical Hormone Replacement Therapy: Precise duplicates of human hormones developed in a conventional way by the pharmaceutical industry and authorised by the regulators such as the MHRA in the UK"
https://thebms.org.uk/publications/consensus-statements/bioidentical-hrt/As you can see, and as sheila99 says, in fact, the hormones in bioidentical medications may not be any different from those in traditional hormone therapy. Sometimes other oestrogens are added to cBHRT such as estriol (though this is available on NHS as a vaginal treatment).
I didn't know there was a "bio identical" vs "body identical". What's the difference?
I hope the above, along sheila99's reply, helps explain that there is no difference but that there are two different types of bio-identical HRT, though the oestrogen in both (apart from the PRE horse urine type) are bio-identical whether compounded or regulated.
