What is the difference between conventional HRT and bio-identical hormones?

Introduction: Why Compare Hormone Therapies?

Menopausal symptoms such as hot flushes, sleep problems and mood swings affect an estimated 75% of all women. No wonder more and more women are looking for the best treatment option. But as soon as you start searching, you quickly encounter a confusing choice: conventional hormone therapy or bio-identical hormones?

The debate around this can be heated. Advocates of bio-identical hormone therapy praise its natural origin, while critical voices point to limited scientific evidence. Both sides make valid points — and that is precisely why it pays to lay the facts side by side.

Hormone therapy is not a one-size-fits-all solution. What works for one woman may not work for another. To make an informed choice, it is essential to first understand exactly what each option entails.

At Menovia, we always tailor therapy to your individual hormone profile — based on blood tests, DNA testing and a comprehensive intake consultation.

What are Conventional HRT and Bio-Identical Hormones?

Before you can make an informed choice, it is important to understand both treatments clearly. The terms may sound technical, but the basic principle is straightforward.

Conventional HRT uses synthetic hormones — substances developed in a laboratory to mimic the action of female hormones. They have been thoroughly researched and have been available through mainstream healthcare for decades.

Bio-identical hormones, by contrast, are chemically identical to the hormones your body produces naturally. They are derived from plant-based sources and can sometimes be compounded to measure, depending on an individual's specific hormonal status.

At Menovia, personalisation is the standard: we use exclusively bio-identical hormones and always set dosages and formulation based on your personal blood values and genetic profile.

Both types of therapy pursue the same goal: relief from menopausal symptoms — but the approach and composition differ fundamentally.

It is precisely that molecular composition that makes the distinction so relevant.

Molecular Structure and Biological Compatibility

Now that we understand what conventional HRT and bio-identical hormones are, it makes sense to look more closely at the crucial difference: molecular structure.

Bio-identical hormones are chemically exactly the same as the hormones the human body produces itself. They fit like a key in a lock onto the hormone receptors in your cells. Conventional synthetic hormones, by contrast, have a slightly different structure — deliberately designed so that they can be patented.

What does this mean in practice? A receptor that receives a "near-fitting" key responds differently than it does to an exact copy. This can create differences in the efficacy and side-effect profile of the hormones, as well as in how the body metabolises them.

This is precisely why at Menovia we choose exclusively bio-identical hormones: the therapy aligns as closely as possible with what your body naturally recognises.

Because hormonal fluctuations affect multiple systems, including your mood and brain, the way hormones are administered is at least as important as their structure.

Administration Methods: Transdermal versus Oral

Alongside molecular structure, the way hormones are administered is another important distinction within hormone therapy. Broadly speaking, there are two main routes: via the mouth (oral) or via the skin (transdermal).

Oral hormones are taken as a tablet or capsule. They pass through the liver before entering the bloodstream — this can make hormone levels less stable.

Transdermal administration — think patches, gels or creams — delivers hormones directly through the skin into the bloodstream. This method often results in a more even hormone profile. In addition, transdermal administration appears to have less of an impact on clotting risk than oral forms.

Bio-identical hormones are available in both forms, but are more commonly applied transdermally. In the next section, we look at the specific advantages this and other properties of bio-identical hormones can offer.

The Benefits of Bio-Identical Hormones

Having discussed administration methods, it is time to look at what makes bio-identical hormones so attractive as a form of hormone supplementation.

The primary advantage is their chemical similarity to the hormones the body produces itself. In practice, this means hormone receptors recognise and process these substances in the way they are accustomed to. This can lead to a smoother action and fewer unexpected side effects for some women.

In addition, personalised hormone therapy offers the possibility of tailoring dosage and formulation to individual needs — something that is less flexible with standard HRT.

In practice at Menovia, we see that women who switch from synthetic to bio-identical hormones often report feeling better in themselves and experiencing fewer side effects — though this varies from person to person.

Bio-identical hormones offer a personalised approach that aligns with the unique hormonal situation of every woman.

Risks and Considerations in Hormone Therapy

The benefits of bio-identical hormones sound appealing, but honesty is called for here. No form of hormone therapy is entirely without risks — and that applies to bio-identical variants too. While recent data is promising, there is insufficient evidence to draw definitive conclusions. Caution may be warranted in patients with an elevated clotting risk, a recent history of cancer, serious cardiovascular disease or other chronic conditions.

A recently published study of 13,000 women in the UK found no increased clotting risk in women using transdermal oestradiol and testosterone in combination with oral progesterone — a widely used hormonal regimen.

In practice, every treatment requires medical supervision and regular evaluation. At Menovia, this is guaranteed: you are guided by BIG-registered physicians, with monthly consultations and blood tests every ten weeks so your treatment is always in step with what your body needs.

Menovia's Choice: Always Bio-Identical

At Menovia, we work exclusively with bio-identical hormones — and that is no coincidence. We believe a treatment works best when it aligns as closely as possible with what your body naturally recognises. Bio-identical hormones are chemically identical to the hormones your body once produced, meaning they are recognised and processed in a familiar way.

While large-scale long-term research in the field of women's health is still ongoing, there are to date no indications of harm from the appropriate use of bio-identical hormones. For synthetic variants, there are studies suggesting an increased risk of clot formation and certain other conditions — a difference we take seriously in our treatment decisions.

Of course, even with bio-identical hormone therapy, good guidance is indispensable. At Menovia, your treatment is therefore tailored step by step to your blood values, DNA and symptom pattern — and adjusted where necessary.
