what the evidence says
Same conditional vitamin D evidence as the category: real benefits when correcting low status, little when topping up the already-replete. This product's trade is convenience against cost per dose; nothing about the evidence differs from cheaper D3.
Plain-language assessment of the human evidence. No cherry-picked citations.
