Breast milk, and food should be the only sources of vitamin C your baby consumes.

Supplementing with vitamin C is unnecessary for most healthy babies and could increase their risk of developing symptoms associated with vitamin C toxicity.

Possible side effects associated with overconsumption of vitamin C include kidney stones, nausea, and diarrhea.

The U.K.’s National Health Service (NHS) only advises that vitamins and mineral supplements be given to infants 6 months of age or older.

Supplementing at 6 months is recommended for infants who aren’t breastfeeding and consume less than 16 ounces (500 mL) of formula per day.

If taking a supplement is deemed necessary, the dosage should be determined by your baby’s healthcare provider.

When supplementing may be appropriate

If you suspect that your baby isn’t getting enough vitamin C, taking a supplement may be necessary.

Vitamin C deficiencies are rare in developed countries, but babies with neurodevelopmental disorders, digestive dysfunction, or cancer may be at an increased risk of developing them.

Severe vitamin C deficiency is the root cause of a serious medical condition known as scurvy.

Symptoms include bleeding gums, bruising, fatigue, loss of appetite, and irritability. If scurvy is left untreated, it can be fatal.

You should never attempt to diagnose your baby with a vitamin deficiency on your own.

Be sure to consult with a qualified healthcare provider before adding any supplements to your baby’s diet. They can determine the safest, most appropriate dosage.

Vitamin C supplements are generally not recommended for babies. In rare instances, supplements may be required, but dosage should be determined by a qualified healthcare provider.
