Vitamin C Intake

Be careful with your supplements. Sometimes too much is too much!

In a study conducted on rats, during the first month of pregnancy, high doses of vitamin C may suppress the production of progesterone from the corpus luteum.[142] Progesterone, necessary for the maintenance of a pregnancy, is produced by the corpus luteum for the first few weeks, until the placenta is developed enough to produce its own source. By blocking this function of the corpus luteum, high doses of vitamin C (1000+ mg) are theorized to induce an early miscarriage. In a group of spontaneously aborting women at the end of the first trimester, the mean values of vitamin C were significantly higher in the aborting group. However, the authors do state: 'This could not be interpreted as an evidence of casual association.'[143] However, in a previous study of 79 women with threatened, previous spontaneous, or habitual abortion, Javert and Stander (1943) had 91% success with 33 patients who received vitamin C together with bioflavonoids and vitamin K (only three abortions), whereas all of the 46 patients who did not receive the vitamins aborted.[144]

Hmmm...I took 1000mg of vitamin C for weeks before transfer, but I stop a couple days before. I hope that's okay...

That dosage was for RATS and they are obviously much smaller. You are fine. Just a general precaution!

Oh hahaha I missed the rat part!

Interesting thread.
