Take with meals containing fats to enhance absorption. Daily dosing is preferred over weekly megadoses.
Possible Side Effects
Excess vitamin D can cause hypercalcemia (nausea, vomiting, constipation). Avoid high doses unless prescribed.
Scientific evidence: Low vitamin D is linked to increased respiratory infections in children (Mailhot & White, 2020; PMC7282029).
