Xi'an Faithful BioTech Co., Ltd: Your Trusted Estriol powder USP Manufacturer & Supplier
Estriol powder USP is one of the three main estrogens in human beings. Metabolites of estradiol and estrone. However, among the activities of estrogen, estriol has the weakest activity. It mainly exists in urine, especially during pregnancy, and its activity is the highest, which is one of the main components to ensure the health of genitourinary tract. The estriol Xi'an Faithful BioTech Co., Ltd provide is a metabolite of estradiol, which plays an important role in regulating fetal development, uterine muscle movement and other processes. Because of the high purity E3 powder we provide, 90% of E3 can be excreted from urine through the kidney without causing uncertain damage to the organism.
What is the physiological function of Estriol powder USP?
E3 is an 18-carbon steroid hormone, and the natural Estriol powder USP in human body is mainly synthesized by fetus and placenta, and enters maternal blood through placenta. In normal pregnancy, E3 increases with the increase of gestational age, and plays an important role in regulating fetal development and uterine muscle movement. In current medicine, it mainly reflects the growth and development of the fetus by monitoring uE3. If there is an abnormal decrease in E3, it may indicate that the experimental body has suffered abnormal fetal death, or some placental diseases, or other hormonal diseases; On the other hand, if your E3 rises abnormally, it may be that the activity of fetal adrenal cortex is enhanced, or there may be a giant fetus, twins or multiple births; Of course, if it is maternal heart disease and cirrhosis, E3 will also rise.

What is the difference between estradiol and estriol?
Estriol powder USP is a kind of weak estrogen, which is mainly produced by placenta during pregnancy and is a marker of pregnancy. At present, it is mainly used locally in clinic to treat menopausal-related vaginal atrophy and dryness. Estradiol is the most important and powerful natural estrogen in women of childbearing age. It is secreted by the ovary and is responsible for regulating menstrual cycle and maintaining female characteristics. It is widely and systematically used in hormone replacement therapy. Simply put, estradiol is the "main force" with comprehensive functions, while estriol is the "special force" with distinctive characteristics during pregnancy and milder local treatment.

FAQ
Q1: What problems is estriol mainly used to treat?
Estriol is mainly used for local (external) treatment to solve the problems caused by the decrease of estrogen level, especially: menopausal reproductive tract syndrome, vaginal dryness, sexual pain, vulvar and vaginal atrophy (such as itching and burning sensation), repeated urinary system infection or urgency; In some cases, it can be used to systematically relieve menopausal hot flashes, night sweats and other symptoms.
Q2: Why is estriol detected in the prenatal examination?
During pregnancy, estriol is produced by the fetus and placenta. Therefore, the level of estriol in maternal blood or urine can directly reflect the functional state of fetal-placental unit. Especially in the case of evaluating fetal health, monitoring the change of estriol level is the most intuitive scheme.
Q3: Is estriol a "biological consistency hormone"? Where does it come from?
Yes, estriol is a biological consistency hormone. This means that its chemical structure is exactly the same as estriol naturally produced by human body. For example, the estriol we provide is not extracted from pregnant women's urine, but a steroid raw material usually extracted from plants such as yam, which is synthesized in the laboratory with high purity and safety.
