Improve vitamin A status

What this outcome means

Vitamin A status reflects whether your body carries enough of this vitamin, from retinoids and stores, to support vision, skin, and immune processes. On DoseRank it maps to a defined health outcome built from human studies on serum retinol, liver vitamin A stores, and dietary intake levels – data sourced from open sources and specialized resources. DoseRank is not medical advice.
