Health and Hormones

Natural progesterone is a remarkably effective, safe and relatively inexpensive therapy for a wide range of disorders resulting from estrogen dominance and progesterone deficiency
— Dr John Lee

Times of hormonal changes such as puberty, pregnancy or menopause are often when health symptoms arise. Today much has been written about the health detriments of an estrogen and progesterone imbalance.  Estrogen dominance is a condition in which one's progesterone levels are abnormally low relative to estrogen levels. Even a woman with low estrogen levels can have estrogen dominance symptoms if she does not have adequate progesterone. According to Dr Lee's research and clinical experience, this imbalance may cause or promote medical conditions such as:

  • acne, breast cancer & uterine cancer, decreased sex drive, depression, endometriosis, fibrocystic breasts

  • fatigue, hair loss, headaches, heart disease, insomnia, infertility, osteoporosis, premenopausal symptoms

  • Polycystic Ovarian Syndrome (PCOS) & fibroids, water retention, weight gain

Based on his review of scientific studies and his clinical experience, Dr Lee concluded that natural progesterone supplementation could help many estrogen dominant women experience relief from such conditions. Below is his list of some of the effects of estrogen dominance and the corrective effects of having adequate progesterone. 


  • Breast cell stimulation (fibrocystic breasts)

  • Increased body fat particularly on the hips and thighs

  • Salt and fluid retention

  • Depression, anxiety and headaches

For Men

We should not forget that progesterone is also important in males.It is produced by the testes and is a prescursor to other hormones in males. The most obvious case of progesterone’s importance is the prostate gland, which is the male equivalent to the female uterus. When progesterone in men is low the estradiol they make causes the prostate cells to grow. Just as excessive estradiol can cause uterine cancer, it is likely that excessive estradiol effect can cause prostate cancer.

Who is Dr John Lee?

Dr Lee was a passionate advocate of using common-sense and simple, straight forward solutions to create and maintain optimal health. He was internationally acknowledged as a pioneer and expert in the study and use of the hormone progesterone, on the subject of Hormone Replacement Therapy (HRT) and health symptoms that women experience. He examined hundreds of scientific studies and concluded that many women suffer from a hormone imbalance that he coined estrogen dominance. 

Why ProgesterAll cream? (natural NOT synthetic)

Progesterone - Progestins

According to Dr Lee misconceptions about progesterone still exist. Many people, including healthcare professionals, think that commonly prescribed progestins such as Provera are natural progesterone or that natural progesterone is a progestin. In reality, progestins are chemicals that have been synthesized from natural progesterone and whose chemical structures have been altered. Some of the unwanted side effects from using synthetic progestins are allergic reactions, acne, edema, hair loss, fatigue and nervousness, to name a few. 

Through his research Dr Lee discovered how to address the fore mentioned health issues with natural ingredients that do not cause the unwanted side effects that progestins do as mentioned above. ProgesterAll™ is a fragrance free cream that contains 20 milligrams of USP Natural Progesterone per ¼ teaspoon of cream. Its unique liposome-mediated delivery system ensures rapid absorption of the ingredients into the skin so that they can be stored in the underlying fatty tissues for transmission to the bloodstream. 

ProgesterAll contains the exact amounts of the ingredients that Dr Lee recommended in his groundbreaking books, including;
