input: [Nutrient] Vitamin B12 [Notes] 
output: Vitamin B12 cannot be obtained reliably in amounts necessary for health from plant foods that are not fortified. Algae, spirulina, alfalfa, comfrey, amaranth, greens, mushrooms, seaweeds, nuts, legumes, and non-fortified fermented soy foods are NOT reliable sources of Vitamin B12. To meet nutritional needs, consume several servings a day of foods fortified with Vitamin B12 (e.g., fortified soy milk), Red Star Vegetarian Support Formula Nutritional Yeast, and/or take a daily Vitamin B12 supplement (sublingual form is more easily absorbed than the pill form). If you have problems producing stomach acid then ask your doctor if you need a Vitamin B12 supplement (poor acid production compromises Vitamin B12 absorption further down in the gut).
