Children who eat no animal foods need a dependable B12 source through fortified foods and/or an appropriate supplement plan. Vegetarian children may get B12 from eggs and dairy, but the foods and quantities they actually eat still matter. Ordinary unfortified plant foods do not provide a dependable substitute. NIH vitamin B12 reference
That makes B12 a different planning question from “How can we add another vegetable?” A varied plate can still leave the B12 source unclear.
For a vegan child, discuss B12 supplementation with a pediatric clinician or registered dietitian as part of the diet plan, rather than waiting for a food diary to show a problem. NHS-hosted guidance for vegan children aged 1–4 specifically advises B12 supplementation. Vegan food guidance for young children
Start with what your child eats, not the diet's name
A vegetarian family might regularly serve milk, yogurt, and eggs. Another might avoid eggs and rarely use dairy. Those patterns call for different conversations about B12. NHS vegetarian-diet guidance
Write down a few ordinary breakfasts, lunches, and dinners. Then circle the food you are counting on for B12. If you cannot identify it, that is a useful question to take to a dietitian—not a reason to blame yourself or pressure your child to eat.
Which foods count as a B12 source?
| Food category | What to check |
|---|---|
| Eggs and dairy foods | Relevant to vegetarian diets that include them; amount and frequency matter |
| Breakfast cereal with added B12 | Check for B12 specifically, not just the word “fortified” |
| Fortified nutritional yeast | Some products contain added B12 and others do not |
| Plant-based alternatives | Confirm B12 on the actual label; do not assume it is present because calcium was added |
Animal foods and B12-fortified foods are the relevant sources here. Beans, vegetables, and ordinary grains do not become B12 sources just because a meal is balanced in other ways. NIH: sources of vitamin B12
How much B12 is in familiar vegetarian foods?
| Reference food | Amount | Approximate B12 |
|---|---|---|
| Milk, 2% fat | 1 US cup | 1.3 micrograms |
| Plain fat-free dairy yogurt | 6 oz (about 170 g) | 1.0 microgram |
| Cooked whole egg | 1 large | 0.5 micrograms |

Make the label useful at home
Keep a photo of the nutrition label for any product you rely on. Note the B12 amount, whether it is given per 100 g or per serving, and how much your child usually eats.
For a fictional example, a cereal with 0.6 micrograms of B12 per 30 g would supply about 0.3 micrograms in a 15 g portion. Adding the full label amount to a small child's bowl would overstate the contribution. Nutrient figures scale with the portion consumed. FDA label guide
Repeat this check if you change brands. The question is whether the new product provides the nutrient you were relying on, not whether its packaging looks similar.
Three ways to organize the conversation
If your child eats eggs and dairy: bring a short record of the foods they regularly accept. Include how often those foods appear, rather than listing foods the household buys but the child rarely eats.
If your child eats fortified foods: bring the labels as well as the meal record. A cereal at breakfast and a different product at nursery are easier to evaluate when their amounts are visible.
If your child already takes a supplement: bring the bottle or a clear photo showing the formulation, amount per dose, and instructions. Tell the clinician how often it is actually given. Do not change the schedule based on the examples in this article.
A short note can be enough: “This is the cereal we use; this is the usual bowl; this is the supplement we have.” You do not need to turn every meal into a measurement exercise to prepare for an appointment.
Does an intake target tell me the supplement dose?
No. The recommended dietary intake and the dose on a supplement are different things; B12 absorption varies with dose and formulation context. A child's supplement plan needs age-appropriate advice. NIH: vitamin B12 intake and absorption
Our existing B12 guide explains food sources and age-based dietary reference amounts. It is not a dosing guide.
Can a food log confirm that B12 status is normal?
No. Food records cannot establish whether a child has a deficiency. If you have concerns about symptoms, growth, or a longstanding lack of a B12 source, seek clinical assessment rather than relying on a reassuring meal total. B12 deficiency can involve both dietary intake and absorption problems. NHS: B12 deficiency
Pip Free can keep one child’s food history in one place using search, barcode scanning, and manual entry. Bring that history and the relevant labels to the appointment so the discussion starts with what your child actually eats. Pip does not diagnose B12 deficiency or choose a supplement dose.
