Reply To: Hi, I have deficiency in Vitamin D and I breastfeed exclusively. I have been prescribed 50,000 IU Vitamin D once a week for 5 weeks. Is it safe to take while breastfeeding? Will my baby get too much through my milk?
First of all please make sure the Vitamin D is D3 and not D2! Vitamin D is safe to take while breast feeding.If you are deficient in Vitamin D, then your breast milk will be deficient in Vitamin D and babies also need Vitamin D. The 50,000 iu of D3 is not too much.
“It takes a Mother having a Vitamin D level of between 40 -60ng/ml herself to then have Vitamin D show up in breast milk for her baby.” This was a study produced by Professor Bruce Hollis and Carol Wagner. You may want to test your baby for a deficiency unless they are being adequately supplemented.
