What is the difference between natural and synthetic progesterone?

Question

I am pregnant and the doctor prescribed me 50 mg of progesterone. The doctor said the pharmacy has to make it, and not every pharmacy carries it. Does this mean it is Natural Progesterone??

Answer 1

Basically, the difference between synthetic progesterone and natural progesterone is that natural progesterone is "bio-identical". Natural Progesterone is the name of the hormone that chemically is exactly like the hormone progesterone produced in the human body.

Bio-identical means that it is the same as what the body makes. This makes them more effective with no side effects when used correctly in dosages similar to the body's normal production.

Since natural progesterone exists in humans and nature, it cannot be patented by pharmaceutical companies.

That means what you are taking is synthetic since the pharmacy is making it.

Answer 2

Synthetic Progesterone

Answer 3

We live in an era when more and more emphasis is being placed on the importance of natural substances. Natural food supplements and herbal formulations are in demand. Homeopathic physicians and caregivers are gaining popularity. Everyone seems to be asking, "What can we do to help the body repair itself in a more natural fashion?"

Many women who take hormone replacement supplements are also asking the "natural vs. synthetic" question. Is natural always better? What is the difference between natural micronized progesterone and the synthetic progestin, medroxyprogesterone, also commonly prescribed as Provera?
The most outstanding difference...

between the two is that medroxyprogesterone is an analog, a "look alike", of progesterone, not truly a progesterone at all, but rather a progestin. The chemical structure of medroxyprogesterone closely resembles the chemical structure of progesterone as it is produced naturally in the human body. But, even a slight difference in the molecular configuration of a compound can produce a totally different response from its natural counterpart.

Progesterone is the oldest steroid hormone—some 500 million years old on the evolutionary scale. All vertebrates produce progesterone, although it is only in higher vertebrates that this hormone is instrumental in the reproductive cycle. In lower vertebrates progesterone functions in relation to glucose metabolism, the development of intelligence and bone formation.

The process of producing natural progesterone, which is made from yams and soybeans, was discovered by Russell Marker, a Pennsylvania State College chemistry professor. While experimenting with sapogenins, a group of plant steroids, in the jungles of Mexico in the 1930s, Marker realized that progesterone could be transformed by chemical process from the sapogenin, diosgenin, which is found naturally, in yams.

Unlike medroxyprogesterone, natural micronized progesterone is an exact chemical duplicate of the progesterone that is produced by the human body.
Another immediate difference...

between medroxyprogesterone and natural progesterone is that the synthetic hormone can actually lower a patient's blood level of progesterone. Some women who take medroxyprogesterone to combat PMS or oppose estrogen in menopause report headaches, mood swings and fluid retention.

On the other hand, women who take natural micronized progesterone often say their mood swings diminish. Women who suffer from migraines as their main complaint with PMS also find that this situation may be corrected by natural progesterone. In its natural micronized form, progesterone acts as a diuretic, which means the women who take these supplements may have to go to the bathroom more frequently, but they are spared the fluid retention and weight gain experienced by women on synthetic progestin.

Prescribed dosages also differ in regard to natural and synthetic progesterone. Synthetic progestin is 10 to 100 times as potent as the natural progesterone. This appears to be a tremendous range, but the doses fall well within those limits.

Medroxyprogesterone is sold in 2.5 milligram, 5 milligram and 10 milligram tables. For example, a woman who is using five milligrams of synthetic progestin would find the corresponding dose of natural progesterone to be between 50 and 500 milligrams. A dosage of 100 milligrams twice a day or 200 milligrams per day of natural progesterone will usually produce endometrial conversion or prevent hyperplasia.

Synthetic progestins were developed with the advent of the birth control pill. The half life of natural progesterone was very short and researchers were looking for an agent that would give a longer half life and yet produce or mimic the effects of progesterone. Birth control pills contain, in most cases, a synthetic progestin and a synthetic estrogen. The very potent synthetic progestins prevent ovulation in a very low dose and, therefore, accomplish their function of birth control.

Conversely, natural progesterone has been use for many years in pregnancy, luteal phase defect and postpartum depression. When a woman is pregnant, her progesterone levels are 30 to 50 times higher than normal. A nursing mother should not be concerned that taking natural progesterone for postpartum depression will affect the baby. After all, the baby has been exposed to tremendous levels of progesterone during its development.

Significant differences exist between synthetic and natural progesterone. Natural progesterone duplicates the body's progesterone exactly, causes fewer side effects and can be more consistently utilized by the body. In the case of natural progesterone versus synthetic progestins in hormone replacement, natural does appear to be better.

Answer 4

natural progeserone is real and synthetic progesterone is synthetic, duh
