What is progesterone and USP natural progesterone?
Progesterone is a steroid hormone produced from cholesterol in the ovaries by the corpus luteum (the tissue that is left behind after ovulation). It is also produced in the adrenal gland in smaller quantities. It is converted in the body to produce other steroid hormones like estrogen, testosterone, cortisol and androstenedione. The main aim of progesterone in women is to sustain any pregnancy that may arise from fertilization of the egg released from the ovary during ovulation.
Progesterone is manufactured from Diosgenin, a substance found in Mexican Wild Yam and also from soybeans. It is converted to bioidentical progesterone in the laboratory.
USP stands for United States Pharmaceutical grade. This means that the progesterone is extracted under the strictest conditions to ensure that it the same as the progesterone that is produced in your body by the corpus luteum and that it is of the highest quality. You may see wild yam creams or those with mexican yam extract. These are a total waste of money! They contain only diosgenin which is cheaper than bioidentical progesterone. It cannot be converted to progesterone in the body. It will not improve your symptoms.
