Phytoestrogens – what are they all about?

Plant-based oestrogens, also known as phytoestrogens, are often mentioned in connection with the menopause. Many women come across terms such as soya isoflavones, red clover or sage when looking for plant-based alternatives. But what exactly are plant-based oestrogens – and why are they receiving so much attention?

Phytoestrogens are natural plant compounds found in certain plants. Their name derives from their structural similarity to the body’s own hormone, oestrogen.

This similarity does not mean that they have an identical effect in the body. Rather, they can bind to specific receptors and are therefore being scientifically investigated in connection with hormonal changes.

The most important groups include:

• Isoflavones
• Lignans
• Cumestans

Isoflavones, in particular, are the subject of numerous studies.

Phytoestrogens are found in various foods and plant extracts. Typical sources include:

• Soya and soya products
• Red clover
• Sage
• Linseed
• Pulses

The isoflavone content varies significantly depending on the plant and how it is processed.

During the menopause, the body’s own production of oestrogen decreases. These hormonal changes can affect various bodily functions.

Due to their structural similarity to oestrogen, phytoestrogens have been studied in a scientific context for many years. They are of particular interest to women who are interested in plant-based ingredients.

It is important to note that phytoestrogens are not hormones, but plant compounds. Their absorption and metabolism depend, among other things, on individual factors such as gut flora, diet and metabolism.

In addition to food, isoflavones derived from soya or red clover are also specifically used in dietary supplements. These supplements contain standardised plant extracts that provide a defined amount of isoflavones.

Many women consciously choose plant-based products during this stage of life to support their bodies. However, dietary supplements are no substitute for a balanced diet and a healthy lifestyle.

Phytoestrogens are natural compounds found in soya, red clover, sage and other plants. Due to their structural similarity to the body’s own oestrogen, they are being studied extensively, particularly in relation to the menopause.
