"How much vitamin D does a breastfed newborn need?"
400 IU daily — recommended by AAP & CDC.
so you don't have to
Thousands of clinical guidelines and peer-reviewed studies from the AAP, WHO, CDC, and other leading health bodies — not blogs, not influencers.
so you don't have to
Every source scored for authority, funding independence, and bias. The unreliable ones get filtered out before they reach you.
so you don't have to
Sources continuously updated, so you get what the evidence says today — not a decade-old study that's been revised or retracted.
so you're not stuck with one source
Consensus aggregated across dozens of independent sources — including where experts agree, disagree, and why.
and actually remember what matters
Quizzes built from the same evidence, so what you've learned actually sticks.
Breastfed newborns need 400 IU (10 mcg) of vitamin D daily, starting within the first few days of life. Continue until they're getting at least 1 liter of vitamin D-fortified formula or milk daily.
"The American Academy of Pediatrics recommends 400 IU of vitamin D supplementation beginning in the first few days of life for all breastfed infants."
"Breast milk alone does not provide infants with an adequate amount of vitamin D… Most breastfed infants will need an additional source of vitamin D."
