Estrogen - Natural Human-Identical
Hormone Replacement Therapy

Estrogen is not a single hormone.  It is a group of three different, but related, hormones that perform functions that we normally attribute to "estrogen".

The three different natural estrogens that predominate in adult women are:

• Estrone (approximately 10-20% of circulating estrogens) = E1 
• Estradiol (approximately 10-20% of circulating estrogens) = E2
• Estriol (approximately 60-80% of circulating estrogens) = E3 thought to be anticarcinogenic; most protective estrogen ever tested against breast cancer.

Conjugated equine estrogen, in contrast, contain the following estrogens:

• Estrone (approximately 75-80%)
• Equilin (approximately 6-5%)
• Estradiol + Others (approximately 5-19%)

Derived from the urine of pregnant female horses is only natural to horses.

How do you know you need hormone replacement therapy?  Either your physician may order a blood serum test or you may choose to a saliva test yourself.

Saliva hormone tests reflect the tissue concentration of your hormones. Blood and serum tests contain the total hormone, but your tissue are only bathed with the active or effective fraction as found in saliva. Active fraction measurements are superior to blood and urine measurements both in diagnosis and treatment. For more information on saliva testing, please click here.
