What year did doctors first prescribe prenatal vitamins?
Also what year did these vitamins start containing folic acid?

In the UK at least they are not a routine, with the exception of folic acid, which is well proven to reduce the risk of neural tube defects, including spina bifida. There was a large study planned years ago to ascertain whether multivitamins were safe and also useful in pregnancy, however it never took place due to the ethical concerns about doing medication studies on pregnant women. Vitamin A is for example definitely potentially toxic.( http://news.bbc.co.uk/1/hi/health/4699041.stm)
In 1991 an MRC-funded randomised, controlled trial shows that folic acid supplements protect women with a prior pregnancy affected by spina bifida or anencephaly (NTDs) from recurrence. The study was halted so all subjects can receive folic acid supplements. Study results are published in The Lancet.Source(s): GP for more years than I care to remember
