What is the Origin of Micronized Progesterone?

The term Micronized Progesterone is descriptive of its manufacturing process and chemical identity. 'Progesterone' identifies the specific steroid hormone, while 'micronized' refers to the process of grinding the substance down to micrometer-sized particles. This formulation technique was developed to overcome the poor oral bioavailability of native progesterone, which is rapidly metabolized by the liver when taken in its standard crystalline form.

What is the Mechanism of Micronized Progesterone?

When taken orally, standard progesterone is largely inactivated by the first-pass metabolism in the liver. The micronization process bypasses this issue by allowing the much smaller particles to be absorbed directly into the lymphatic system or to pass through the liver with a reduced rate of degradation. Once absorbed, the bioidentical progesterone acts by binding to the progesterone receptors in target tissues, such as the uterus and brain, initiating the physiological effects necessary for reproductive and neuroendocrine balance, including the calming effects on the central nervous system.

Micronized Progesterone

Meaning

Micronized Progesterone is a pharmaceutical preparation of the naturally occurring hormone progesterone that has been mechanically processed into extremely fine particles. This reduction in particle size, or micronization, significantly increases the surface area of the compound, thereby enhancing its absorption and bioavailability when administered orally or via other routes. Clinically, it is used extensively in Bioidentical Hormone Replacement Therapy for women, particularly to protect the endometrium and to address symptoms associated with progesterone deficiency, such as sleep disturbances.
