Hello, I am looking for an opinion on D3 supplementation for newborns. We have a 3-week-old daughter whose physician's assistant recommended we supplement with 4000 IU. I believe this was an accident — it seems to be an adult dose — but that is not the reason I'm writing. It prompted me to look further into infant dosing recommendations, and what concerns me is the handful a handful of studies I found correlating early supplementation with an INcreased risk of allergies/atopy later in life. I put the citations below. So my questions are about about the benefits vs. risks of supplementation. Are they two sides of the exact same coin? Or can you suggest a strategy that might provide one without the other? For example: delaying supplementation until a certain age, or keeping her blood levels within some intermediate range. What would consider a minimum effective blood level to realize the important benefits? Thanks! Milner J D, Stein D M, McCarter R, Moon R Y.
