It is the natural biomimetic rhythm that is missing from most hormone replacement therapies which women in menopause are taking today to feel better, avoid hot flashes, and increase libido. People have become accustomed to talking about bio-identical hormone replacement therapy (BHRT) for menopause.

Questions about Hormone Replacement Therapy (HRT) began with the Women's Health Initiative (WHI). This study of more than 161,000 women was designed to identify the benefits and risks of using menopausal hormone therapy (MHT) to prevent chronic diseases such as heart disease, breast and colorectal cancer, and osteoporosis in postmenopausal women. Many people did not realize that the results of WHI Study dealt with women over 65 who were taking synthetic hormone replacement therapy via the drugs Premarin and prempro only. The study was ended mid-stream in 2002 when WHI investigators found that the possible risks of this synthetic therapy exceeded the safety limits established at the beginning of the study.

In fact, the term "bio-identical" has become a catch all phrase for anything that is not a synthetic hormone. Bio-identical hormone products are usually formulated from natural plant sources to match the chemical structure of hormones produced naturally by the human body. Technically, the body can't distinguish bio-identical hormones from the ones produced by the ovaries.

The fact is, the term bio-identical can only be truly accurate if the hormones are reproduced to mimic the hormones found in the body as well as the natural biological process, which has a rhythm. Hormones should be called bio-identical only if they are dosed in a biomimetic fashion - in a rhythm - or in a multi-phasic rhythmic dosing schedule. Biomimetic is the scientifically accurate term.

The circadian clock in our cells measures one 24 hour spin of the earth. For 28 days the moon tracks the repeat of that cycle - which is what our bodies also do. Biomimetic Hormone Replacement Therapy uses this natural rhythm of nature to establish the proper doses of estradiol and natural progesterone that mimic the natural hormones produced by the body, which restore the hormone levels of youth.

What is meant by the rhythm? The body's rhythms are governed by a master clock working like a conductor. It strikes up one section of the body's orchestra as another quiets down, taking its main cue from light signals in order to stay in sync with the 24-hour day. Our body's hormones surge and ebb to this maestro's wand, controlling endocrine function including a woman's sexual health.

Biomimetic Hormone Restoration Therapy (BHRT) is derived from plant sources, and mimic in the body's natural undulating, or wavelike, rhythms of the hormone blood levels in a normal menstrual cycle. So it is this natural rhythm that is missing from all other hormone replacement therapies.
