  • Normal” folic acid
  • Supplements that contain a special form of folic acid: It is a more active type, called methyl-tetrahydrofolate (also called 5-methyl-tetrahydrofolate, 5-MTHF or methylolphin).

Folic acid in the form of methyl tetrahydrofolate

Healthy people and pregnant women can take “normal” folic acid.

This refers to people who are in the following cases: people who smoke, people with high homocysteine ​​levels, people with chronic renal failure.

It is not recommended that pregnant women take vitamin B9 in the form of 5-MTHF for the following reasons:

  • In a double-blind 2015 study of more than 100 pregnant women, it was determined that there was no difference between using “normal” vitamin B9 and the “methyl” form. It is also worth mentioning that women who used the “methyl” form had no more or less problems than those who used the “normal” form of the supplement.
  • Although it may seem that this potent form of vitamin B9 is more “effective”, its toxicity is also a little less investigated.
  • Many times “vitamin B9 methyl” (methyl-tetrahydrofolate) supplements are accompanied by B6 and B12 (also in its methyl form). High doses of vitamins can have unexpected effects.

Are multivitamins recommended in pregnancy?

It is not recommended to take multivitamins during pregnancy. Only the 4 nutrients that are required, such as vitamins B9 and B12 already mentioned in the text, iodine and sometimes iron, should be taken.

For the rest of nutrients, it is not necessary to take any supplement since it is much better to get them through food.

In addition, some supplements that appear harmless can be toxic or harmful by containing vitamins in an inadequate or chemical form, as is the case with some vitamin A supplements (retinoids) or some forms of vitamin E.
