Deficiencies
What running low looks like
Nutrient shortfalls often show up as vague, easy-to-dismiss symptoms long before anything gets diagnosed. Each entry links to the nutrient behind it and what to eat.
Iron-deficiency anemia
The most common nutritional deficiency worldwide; low iron impairs oxygen transport in the blood.
Linked to iron
Vitamin B12 deficiency
Nerve and blood-cell effects from low B12, common in older adults due to reduced absorption rather than low intake.
Linked to vitamin b12
Vitamin D deficiency
Widespread deficiency linked to reduced sun exposure and low dietary intake; weakens bones and affects immune function.
Linked to vitamin d
This is general nutrition information, not a diagnostic tool. If symptoms here sound familiar, that's a reason to talk to a doctor — blood work is the only way to actually confirm a deficiency.
