Maternal supplementation with 6400 IU/day of Vitamin D3 during lactation safely and significantly increases both maternal and infant circulating 25(OH)D levels, rendering infant oral supplementation unnecessary.
If you are breastfeeding, standard prenatal vitamins (400 IU Vitamin D) are likely not enough to keep you and your baby healthy regarding Vitamin D, especially if you have limited sun exposure. This study suggests that taking 6400 IU of Vitamin D3 daily is safe and effectively boosts Vitamin D levels in both you and your baby, potentially removing the need for separate infant drops. Always consult your doctor before starting high-dose supplementation.
High-dose (6400 IU/day) vitD3 safely and significantly increased maternal circulating 25(OH)D and vitD from baseline compared to controls... Thus, a maternal intake of 6400 IU/day vitamin D elevated circulating 25(OH)D in both mother and nursing infant.
