Which nutrients are most important during pregnancy? Folic acid, Iodine, Iron.

Folic acid(B9):
Folic acid helps the development of the fetal central nervous system. The lack of it might cause congenital neural tube defects in the fetal brain and spinal cord.

※Recommended daily intake is 500-800 micrograms (mcg) per day for pregnant women.

Iodine:The main component of synthetic thyroid hormone, helps maintain basic metabolic function. 

Iodine deficiency can easily lead to goiter, miscarriage, stillbirth, fetal congenital malformations, IQ and cognitive development delayed.

※Recommended daily intake is 140-200 micrograms (mcg) per day for pregnant women.


Iron(Fe): It helps to produce erythrocytes. Iron deficiency in early pregnancy can easily lead to premature birth, low birth weight or even stillbirth.

※Recommended daily intake is 15 milligrams (mg) per day for pregnant women.

Besides these three kinds of nutrients, are there any other nutrients needed?

Vitamin D is also important. Vitamin D deficiency can easily cause premature birth, preeclampsia, gestational diabetes and immune system problems.

You can do a blood test to confirm whether vitamin D is lacking, and take 800-2000 (IU) daily supplement according to the report to increase the pregnancy rate.


Vitamin B12: Deficiency of Vit B12 easily leads to fetal neural tube defects.

※Recommended daily intake is 2.6 micrograms per day. Generally, vegetarians are more likely to be deficient in vitamin B12!

There are also three important nutrients in male fertility. They are Arginine, Selenium and Zinc.

Here's the summary of both male and female pre-conception nutrition.


Only when you have special eating habits or deficiencies found after a blood test do you need additional health supplements.

Health supplements are supplementary. Please consult a pharmacist or doctor before taking it!
