USP (U.S. Pharmacopeia) provides standards for more than 3,700 medicines, dietary supplements and dosage forms. The "USP" on natural progesterone USP is given because it meets standards of purity (99%). To visit the website of U.S. Pharmacopeia, please click the link at the bottom of this page.

Natural hormones are developed through DNA technology. Sterol analogues from certain plants (wild yam) are combined with specific bacteria (microbial fermentation) and the resulting hormone is bio-identical in chemical structure to the hormone produced by the human body. See similar questions...

Synthetic progesterones (called 'Progestins') are drugs created and manufactured by drug companies. They are patented molecules not found in nature or our bodies. Because there are known side-effects, they are only available by prescription and require physician oversight. Synthetic progesterone once inside your body seeks out and resides in the cells, which have progesterone receptor capabilities. See similar questions...

Natural" progesterone (also termed USP Progesterone) refers to a single molecular structure that is "bio-identical" to the progesterone molecule that the body makes. Synthetic "progestins" or "progestogens," do not exactly duplicate the body's own progesterone molecule. They mimic the body's progesterone closely enough to bind to progesterone receptor sites and have some progesterone-like effects, but they do not deliver the full range of "messages" that a natural progesterone molecule would.

In his book, "What Your Doctor May Not Tell You About Menopause," Dr. Lee breaks down the adequate daily amount of natural progesterone USP to be "20 to 30 milligrams per day." He further writes, "let's say each two-ounce jar or tube of 3 percent (by volume) or 1.6 percent (by weight) progesterone cream contains 950 milligrams." This would mean that a two-ounce jar with 950 mg has forty-eight 1/4 teaspoon applications and each application would provide about 19.79 mg of progesterone. See similar questions...

Natural progesterone, a cholesterol derivative, comes from the Mexican yam or soybeans. It matches exactly the chemical formulation of the body's own progesterone and thus causes no side effects. Manufacturers of synthetic progesterone alter the chemical makeup of progesterone in order to create progestins. See similar questions...

Consumers should be wary of the term "natural" when used to describe cleaning products. All of the chemicals used to make the ingredients that go into cleaning products are found in nature. Very few chemicals extracted from plants or the earth are used without further processing to obtain ingredients that perform a cleaning function. Thus, the term "natural" to describe a final product can be misleading. See similar questions...

USP stands for United States Pharmacopoeia which is the international standard of purity for substances used in the manufacture of drugs and cosmetics. In the case of Natural progesterone USP simply confirms that the progesterone is the identical molecule as is produced by the human body. The title progesterone USP, identifies the progesterone as natural and differentiates it from the synthetic versions which are often referred to as progestins or progestogens.

Oasis Serene Natural Progesterone cream uses USP micronized progesterone derived from the wild yam plant.. All USP progesterone creams are derived either from the soy plant or wild yam. Progesterone from soy and from wild yam produce the exact same quality of progesterone. See similar questions...

Synthetic progesterone (progestins) simply do not perform the same functions in the body. They can even lower your levels of progesterone. Natural progesterone is also a precursor to many other hormones in your body, so it is imperative that it be used in its natural form. See similar questions...

Your doctor or health care professional is truly interested in seeing you regain and maintain good health. Have him or her simply follow along with your use of Natural Progesterone. Another option is to supply a copy of one of Dr. Lee's books. See similar questions...

Progestins do not convey the full spectrum of progesteron's benefits as listed above and they have numerous potential deleterious side-effects not found when using natural progesterone. The natural hormones are more quickly metabolized and excreted than the synthetic versions. Progesterone has no known side effects. See similar questions...

During the years before actual menopause, estrogen may be decreasing only slightly and ovulation has ceased or is rare. Without ovulation, progesterone production is essentially zero making a woman estrogen dominant. Further supplementing the dominant estrogen simply does not make sense, and synthetic progestins have undesireable side effects. See similar questions...

Pharmaceutical progestins do not appear in the biosynthetic pathway. The fact is, they are not found in any living forms. Furthermore, being foreign to all living things, they are patentable and thereby potentially more profitable. Natural Progesterone is from a plant extraction and is not patentable See similar questions...

Some of the known side effects of synthetic progestin include causing cancer, lowering natural Progesterone levels, weight gain, and worsening PMS symptoms. Natures Light, Natural Progesterone Cream comes from nature and therefore is closer to your body's hormonal makeup and has no side effects. Consider using a natural alternative, even if it's not Natures Light, Natural Progesterone Cream. See similar questions...
