Vitamin D
Vitamin D (25-OH) — optimal range for vegans & vegetarians
The storage form of vitamin D in blood.
Optimal range
30–60 ng/mL
How a value is read
| Deficient | < 20 ng/mL |
| Below optimal | 20 – 30 ng/mL |
| Optimal | 30 – 60 ng/mL |
| Above optimal | 60 – 100 ng/mL |
| Markedly high | > 100 ng/mL |
Bands are given in the marker's canonical unit; values in other units are converted automatically.
Why it matters on a plant-based diet
Nearly absent from plant foods; vegans usually need lichen-derived D3 or D2. Magnesium is a cofactor for activating vitamin D — low magnesium blunts supplementation.
A single marker decides nothing
Deficiencies mask one another: high folate hides low B12, inflammation inflates ferritin, low zinc mimics iron deficiency. VEGALYSIS reads the whole picture and explains the links.
