Natural Progesterone

The use of natural progesterone creams was pioneered by Dr John Lee, a Californian family doctor.

Over a period of 20 years Dr Lee observed the effect of progesterone creams on patients who used them and proposed a new syndrome, which he named “oestrogen dominance”, in which women suffer a variety of symptoms as a result of the toxic load of oestrogen-like chemicals now present in our environment and other factors.

Dr Lee also proposed that progesterone is more important than oestrogen in preventing osteoporosis and menopausal symptoms. None of these theories have yet been proved as Dr Lee was not able to fund double blind placebo controlled or comparative studies himself. Double blind placebo-controlled trials with progesterone creams are now under way in the UK and America.
