The difference between Livermin and estrogen is that Livermin does not contain hormones, while estrogen is contained in estrogen. Although it does not contain estrogen, Livermin can be used orally to improve the symptoms caused by estrogen deficiency, such as hot flashes, excessive sweating, insomnia and excessive dreaming during perimenopause or menopause. However, the clinical effects of Livermin will be delayed during the course of administration, and the clinical symptoms will only improve after about 4 weeks of administration. You can continue to take it and stop taking it once the clinical symptoms have improved.
