Progesterone is necessary throughout gestation for the survival of the fertilized egg, the resulting embryo, and the foetus. During pregnancy the placenta produces 300mg to 400mg of progesterone per day. Progesterone has many other functions, among them protecting against fibrocysts, helping the body use fat for energy, and helping normalize blood clotting and blood sugar levels. It is believed that progesterone balances oestrogen and that an overproduction of oestrogen can lead to health problems. Too much oestrogen is known as oestrogen dominance .
Natural progesterone is progesterone.
It is derived from a natural source and then converted to progesterone. Natural progesterone has the same molecular configuration as the progesterone produced by the body and can be used to supplement the progesterone produced by the body and to balance oestrogen and progesterone levels.
