When Almavivo suggests Vitamin B12
- If you reported a plant-leaning or pescatarian diet: studied for B12 status in low animal-product diets.
- If you flagged low or borderline B12 labs: studied for correcting documented B12 inadequacy.
- If you reported low energy: studied for fatigue in suboptimal-B12 contexts.
- If B12-relevant signs converged in your answers (e.g. sore or smooth tongue, pale skin, plant-leaning diet) — note: greying that runs in your family is not counted as a signal: studied for B12 status correction in suspected deficiency.
- If one B12-relevant body sign appeared with at least one supporting risk factor: studied for B12 status correction in suspected deficiency.
