Gefeliciteerd met je zwangerschap TweelingB!
Ik ben nog een beetje in dubio over de hoeveelheid. De studie uit 2016 zegt het volgende:
The mothers were recruited at the time of their child’s birth between 1998 and 2013 and followed for several years, with the mother’s blood folate levels checked once within the first one to three days of delivery. The researchers found that one in 10 of the women had what is considered an excess amount of folate (more than 59 nanomoles per liter) and six percent had an excess amount of vitamin B12 (more than 600 picomoles per liter).
The World Health Organization says that between 13.5 and 45.3 nanomoles per liter is an adequate amount of folate for a woman in her first trimester of pregnancy. Unlike with folate, there are not well-established thresholds for adequate vitamin B12 levels.
Maar hoeveel nanomoles = microgrammen geen idee. Ik ben geen scheidkundige 😵
