Natural oestrogen supplements are increasingly popular. These so-called phyto-oestrogens are derived from plants. Surprisingly, they have an affinity for the receptors in the human body which are designed to attract oestrogen-type molecules. But, this affinity for oestrogen receptors is much lower than that of human or other animal oestrogens.

Most experts agree that phyto-oestrogens can help with some of the symptoms of menopause such as hot flushes. The supplements which are most effective are black kohosh, genistein and soy-based products.
However, the evidence from clinical trials is that these supplements have little or no effect on other problems associated with menopause, such as a dry vagina, developing osteoporosis, an increased risk of heart disease or for improving brain function.
Another possible problem with them is that much higher doses of phyto-oestrogens are needed to control symptoms like hot flushes than are needed with conventional oestrogen-containing products. This means that certain oestrogen-sensitive cancers such as breast cancer may be worsened in women taking these products.
As with all therapies – conventional or otherwise – always discuss its use with your doctor.
