Plant-based nutrition supplement guide
On plant-based diets, B12, iron, vitamin D and omega-3 are commonly watched. B12 in particular is nearly absent in plant foods, so many plan a source.
Vitamin B12
B12 is found in animal foods and scarce in plant foods; fortified foods or supplements are common sources.
Iron absorption
Plant iron is less absorbed; pairing with vitamin C is often suggested. Confirm need via testing.
