The American Academy of Pediatrics recommends that infants receive 400 IU of vitamin D3 daily. Unfortunately, most babies don't receive enough vitamin D from sun exposure or their diets to reach the recommended daily intake. Baby's Super Daily D3 provides 400 IU (10 mcg) of vitamin D3 in one convenient flavor-free drop. Place one drop in your baby's formula, or use it while breastfeeding.
