Yes, according to current scientific knowledge, babies can be fed a vegan diet if the diet is carefully planned, age-appropriately implemented, and accompanied by a pediatrician. The decisive factor is not primarily whether a baby is fed vegan or omnivorous, but whether all necessary nutrients are reliably covered.
→ A detailed overview is available in our PREGNANCY and BREASTFEEDING GUIDE, which we have developed together with Dr. Anika Döll and nutrition scientist Christina Dengg (BBSc, MSc). The guide is currently published in German, but can be translated using tools like ChatGPT or Google’s browser translator. The guide provides a well-founded introduction and general guidance, but it does not replace individual nutrition counseling or medical care. Especially during pregnancy and breastfeeding, we recommend seeking personalized support from qualified healthcare professionals. Examples include Dr. Anika Döll, Christina Dengg, or Dominik Machner.
Is a vegan diet healthy for babies? What professional organizations say
Major professional societies usually do not give a blanket yes, but also no general no. The data on vegan diets in infancy is limited but much more nuanced than often portrayed. The ESPGHAN (2025) in 2025 rates a vegan diet for infants as feasible under the following conditions:
- Careful planning
- Reliable supplementation
- Pediatric monitoring and control of growth and critical nutrients.
Available reviews support this: Brits & le Grange (2025) emphasize that a well-planned purely plant-based diet is fundamentally possible for infants. Breast milk is considered the ideal food, provided the mother is adequately supplied with the relevant nutrients. If breastfeeding is not possible, specially formulated soy infant formula is recommended, while ordinary plant milk is rejected. The review by Sutter & Bender (2021) also concludes that vegan-fed children, including infants, can grow normally with good planning and supplementation.
Which nutrients do vegan-fed babies need?
If a baby is fed a vegan diet, Vitamin B12 must be reliably supplied. Adequate supply through plant-based foods alone is not possible. Depending on the nutritional situation, the supply can come from an adequately nourished breastfeeding mother, from suitable infant formula, and/or from an age-appropriately dosed Vitamin B12 supplement for the child.
Furthermore, according to current guidelines in German-speaking countries, all infants are recommended to receive 400-500 IU of Vitamin D daily until their second early summer. Please note: Administer tablets only when completely dissolved!
Sufficient iodine supply should also be ensured. This is especially true in regions with low iodine content in the soil, such as Central Europe. The supply can come from breast milk, suitable infant formula, or a supplement.
In addition, depending on the individual situation, the following nutrients should be monitored:
- Iron
- Zinc
- Calcium
- DHA (Omega-3)
→ Some of the mentioned nutrients require special attention in infants regardless of the diet. Which supplements are actually necessary should always be decided with pediatricians or qualified nutrition professionals based on the individual supply. Especially with iodine and fat-soluble vitamins, an overdose is possible. Many nutrients can also be covered by a vegan diet. (vegan iron sources see 6.1 Nutrient Guide; vegan zinc sources see 6.4; vegan calcium sources see 6.2)
How are supplements administered?
For infants, supplements are available in different forms depending on the nutrient, for example, as drops or syrups. Which form is suitable depends on the age and the specific preparation.
Supplements for infants should not be added to food by feel, but should be used in an appropriate form and dosage. The specific supplementation for vegan-fed infants should be individually coordinated with pediatricians or nutrition professionals. In addition to the vitamins already mentioned, in Germany, vitamin K is routinely administered as part of the U1, U2, and U3 preventive examinations.
Vegan nutrition in the first year of life
In the first months of life, breast milk, provided the mother herself is adequately supplied with critical nutrients, is the best nutrition for a baby - regardless of the parents' diet. An overview table for supplementation during vegan breastfeeding can be found in our PREGNANCY and BREASTFEEDING GUIDE under 7.2.2.
If not breastfeeding, only an approved infant formula should be used. Normal plant milk is not a suitable substitute for babies in their first year of life!

Why medical supervision is important
Regular preventive examinations are important for all children - regardless of their diet. They serve to monitor growth, development, and general health and to treat them if necessary.
For vegan-fed babies, regular monitoring of growth, development, and, where appropriate, relevant laboratory values is recommended. This helps identify potential nutritional deficiencies early, allowing them to be addressed easily in many cases.
Feeding babies vegan - frequently asked questions
Is a vegan diet dangerous for babies?
No, not generally. Risks primarily arise from an inadequately planned diet or an insufficient supply of critical nutrients. This can also occur with a mixed diet.
Do babies need Vitamin B12 on a vegan diet?
Yes, Vitamin B12 should be reliably supplemented with a purely plant-based diet. In infancy, this can be done via breast milk, suitable infant formula, or a supplement.
Can vegan-fed babies grow normally?
Yes. According to current scientific knowledge, vegan-fed babies can grow normally and develop age-appropriately with careful planning, adequate nutrient supply, and regular pediatric supervision.
Is plant milk suitable for babies?
No. Conventional plant milk such as oat, almond, or soy drinks are not a substitute for breast milk or infant formula, as they do not meet the special nutrient needs of babies.
Do vegan-fed babies need special infant formula?
Yes, if not breastfeeding, only an approved infant formula should be used. Normal plant milk is not a suitable substitute.
Conclusion: Feeding babies vegan - Is it healthy and possible?
Yes. According to current scientific knowledge, babies can be fed a vegan diet if the diet is carefully planned, supplemented, and regularly pediatrically monitored.
Whether a baby grows up healthy does not depend solely on the chosen diet, but on whether it reliably covers the nutrient requirements and is implemented in an age-appropriate manner.
