Now we know how important prenatal vitamins are. But often there is a question of their contribution towards weight gain. The answer is no. There is no scientific proof to support the statement that prenatal vitamins can cause any weight gain.

Prenatal Vitamins And Weight Gain

During pregnancy, women tend to gain weight considering a number of lifestyle changes they undergo. For instance, women will often have a fondness for sweets when they are in their first trimester. More sugar leads to gaining more kilos. Iron supplements are known to cause water retention and inability to excrete. This way women might be under the impression that they have gained weight.

To add to this, with every passing week, you might gain a pound or two which is not unnatural and there is nothing to be concerned of. It is completely healthy and has nothing to do with consuming prenatal vitamins. If you are suffering from any other serious side effects, we suggest you talk to your OB/GYN to conduct a thorough examination.

Side Effects Of Prenatal Vitamins

Though generally devoid of side effects, in some cases it can trigger irrational symptoms. They could be-

  • Continuous vomiting-Not a surprise when we are pregnant.
  • Hard stools– This could be due to the Iron they consume.
  • Flatulence-Improper digestion can cause this.
  • Skin rashes– In very rare cases.
  • General allergies– This can be mitigated by taking ones that aren’t allergic
  • Blood clots– Appearing without any rhyme or reason

Talking to your healthcare provider should provide some relief and if the symptoms become severe or the allergy persists, make sure you go to the hospital immediately.

Should One Stop Taking Prenatal Vitamins If It Has Side Effects?

No, it is not safe to stop taking prenatal vitamins without any cause. You can always change the brands but a total stoppage may increase risks during childbirth. According to a study conducted by John Hopkins, women who take prenatal vitamins 3-5 times a week have a “markedly lower risk of having children with an autism spectrum disorder.” Please follow the instructions of your doctor or healthcare provider.


Prenatal Vitamins are key to the holistic development of your fetus. Despite many viral claims, it cannot cause any change in your weight, and if any change is noticed it is due to the condition. In extreme cases, it will show some side effects so talking to a doctor will prove helpful.

Nevertheless, it shouldn’t be stopped prematurely. Rely and place your trust in your body.
