10 food supplements for vegetarians
A vegetarian diet is becoming increasingly popular for various reasons: health, the environment, animal welfare or love of animals and much more. However, as with any diet, it is important to ensure that the body receives all the necessary nutrients. This is where food supplements come into play, which are specially tailored to the needs of vegetarians. In this article, you’ll learn all about the most important supplements for vegetarians, how they can support your health and which plant-based foods can be used as meat substitutes.
What does it mean to be vegetarian?
Being vegetarian means practising a diet that excludes the consumption of meat and fish.
More precisely, the term “vegetarianism” goes back to the founder of classical vegetarianism, the philosopher Pythagoras. The Latin word “vegetare” means “to animate” and describes the fact that only products from living animals are consumed alongside plant-based foods . This definition implies a diet that promotes and respects life without ending the lives of animals for food .
The decision to go vegetarian can be based on various personal, health, ethical or environmental reasons. There are various forms of vegetarianism, which differ in their strictness and the foods allowed:
Types of vegetarianism
- Lacto-ovo vegetarianism: This form of vegetarianism excludes meat, fish and poultry, but allows the consumption of dairy products and eggs. This is the most widespread form of vegetarianism.
- Lacto-vegetarianism: Lacto-vegetarians abstain from meat, fish, poultry and eggs, but consume dairy products such as milk, cheese and yoghurt.
- Ovo-vegetarianism: Ovo-vegetarians do not eat meat and dairy products, but they do consume eggs.
- Veganism: This strictest form of vegetarianism avoids all animal products, including meat, fish, poultry, dairy products, eggs and often honey. Vegans also avoid products that contain animal ingredients or that use animals in their production.
Reasons for a vegetarian diet
- Health benefits: Many people choose to follow a vegetarian diet for health reasons. Vegetarians aim to reduce the risk of chronic diseases such as heart disease, diabetes and certain cancers through a well-planned vegetarian diet.
- Ethical considerations: Animal welfare is another important reason why people go vegetarian. They reject the killing and exploitation of animals for food and are in favour of an animal-friendly lifestyle.
- Environmental awareness: The environmental impact of meat production is considerable. Vegetarians help to reduce the ecological footprint through their lifestyle, as a plant-based diet uses fewer resources such as water and land and produces fewer greenhouse gases.
- Religious and cultural influences: Many cultures and religions have traditions and rules that promote a vegetarian diet. For example, many Hindus and Buddhists practise a vegetarian lifestyle.
Are food supplements useful for vegetarians?
Firstly, let’s look at the controversial question of whether dietary supplements are necessary for vegetarians. The answer is: it depends on various factors such as individual diet, lifestyle and genetic predispositions . Scientific studies (listed at the end of the article) show that certain nutrients that may not be sufficiently present in a typical vegetarian diet can be usefully supplemented with food supplements .
Brief summary of the scientific findings and recommendations
- Vitamin B12: A crucial nutrient found almost exclusively in animal products. Vegetarians, especially vegans, are therefore more susceptible to vitamin B12 deficiency. A study in the“American Journal of Clinical Nutrition” showed that 92% of vegans and 77% of vegetarians who do not take supplements have low vitamin B12 levels.
- Vitamin D: Vitamin D, which is mainly synthesised by sunlight, can be difficult to obtain in northern latitudes and during the winter months. Supplementation is often recommended to ensure adequate bone health. TheHarvard School of Public Health recommends vitamin D supplementation for vegetarians, especially those in sun-deprived areas.
- Iron: Plant sources of iron are less bioavailable than animal sources. A meta-analysis in the“Journal of Nutrition” shows that vegetarians have a higher risk of iron deficiency and that supplementation can effectively improve iron levels .
- Omega-3 fatty acids: These are important for heart health and cognitive function. The main sources of EPA and DHA are fish and seafood. Vegetarians can consume ALA (a plant-based omega-3 fatty acid) from flax and chia seeds, but the conversion to EPA and DHA is inefficient. A study in the“Journal of Clinical Lipidology” therefore recommends supplementation with algae oil, which provides EPA and DHA directly.
- Iodine: An essential nutrient for thyroid function that is often found in seafood. Vegetarians who consume little iodised salt or foods containing iodine could benefit from supplementation. According to theWorld Health Organisation, sufficient iodine intake is particularly important for vegetarians to prevent thyroid disease.
Overall, the scientific evidence shows that dietary supplements for vegetarians are not only useful, but in individual cases necessary to avoid nutrient deficiencies and ensure optimal health.
ATTENTION: Not all food supplements are vegetarian
It is important to note that not all supplements are suitable for vegetarians as some of them may contain animal ingredients. For example, many capsules are made from gelatine, an animal product derived from the collagen of pigs or cattle. In addition, certain vitamins such as vitamin D3 can be obtained from lanolin (sheep’s wool fat) or fish oil . Omega-3 fatty acids are also often made from fish oil, although there are plant-based alternatives such as algae oil. Kingnature, for example, offers a vegan option for omega-3 supplementation.
To ensure that supplements are vegetarian, consumers should check the ingredients list carefully and look out for seals such as “vegetarian”, “vegan” or specific information from the manufacturer. Many manufacturers also offer explicitly vegetarian or vegan alternatives that are free from animal ingredients. Conscious purchasing and careful selection of products are therefore crucial to ensure that dietary supplements are in line with your own dietary principles.

Tips for a balanced vegetarian diet
A balanced vegetarian diet can, through planning and preparation, ensure that all the necessary nutrients are consumed in sufficient quantities. Here are some essential tips that can help:
Meal planning and preparation
The foundation of a balanced vegetarian diet is careful meal planning and preparation. This starts with creating a weekly meal plan that includes a variety of vegetables, fruits, whole grains, legumes, nuts and seeds. This variety ensures that you get a wide range of nutrients. It’s helpful to prepare meals in advance to avoid the temptation to reach for processed foods. Batch cooking, where large quantities of dishes are prepared and frozen in portions, can be particularly practical.
Integration of nutrient-rich foods
A balanced vegetarian diet should be rich in nutrient-dense foods. Pulses such as lentils, beans and chickpeas are excellent sources of protein and iron. Green leafy vegetables such as spinach and kale provide important vitamins and minerals, including iron and calcium. Whole grains such as quinoa, oats and brown rice provide complex carbohydrates and fibre. Nuts and seeds, including chia, flax and hemp seeds, are excellent sources of omega-3 fatty acids and protein. Fermented foods such as sauerkraut, kimchi and natto can support gut health and provide vitamin K2.
Use of supplements when needed
Although a well-planned vegetarian diet can provide many nutrients, there are certain nutrients that are more difficult to obtain from purely plant-based sources. These include vitamin B12, vitamin D, omega-3 fatty acids (EPA and DHA), iron and iodine. In such cases, the use of food supplements can be useful. It is important to regularly check your nutritional status and, if necessary, speak to a doctor or nutritionist about appropriate supplementation. Vitamin B12 should be supplemented by almost all vegetarians, as it is not found in sufficient quantities in plant-based foods. Vitamin D may be particularly necessary in the winter months or when there is little sunlight exposure. Omega-3 fatty acids can be supplemented with algae oil capsules, which provide a direct source of EPA and DHA.
Bioavailability of nutrients
An often overlooked aspect is the bioavailability of nutrients in plant foods compared to animal products. Bioavailability refers to how well and efficiently a nutrient can be absorbed and utilised by the body. For example, iron from plant sources (non-haeme iron) is less bioavailable than iron from animal sources (haeme iron). However, absorption can be improved by combining plant sources of iron with foods containing vitamin C. Such tips can help to maximise the efficiency of nutrient absorption.
Combination of foods
The right combination of foods can significantly improve the absorption and utilisation of nutrients. Certain nutrients are better absorbed when eaten together. This is particularly important for vegetarians to ensure that all essential nutrients are absorbed efficiently. For example, combining vitamin C-rich foods (such as peppers or citrus fruits) with iron-rich plant foods improves iron absorption. Similarly, combining different protein sources (such as beans and rice) can provide all the essential amino acids the body needs. Here are some good food combinations that vegetarians can utilise:
Nutrient target | Food combinations | Explanation |
---|---|---|
Improved iron absorption | Lentils Bell peppers, spinach Orange slices | Vitamin C from peppers and oranges improves the absorption of non-haem iron from lentils and spinach. |
Complete proteins | Rice Beans, hummus Wholemeal bread | The combination of different vegetable proteins provides all the essential amino acids. |
Calcium and vitamin D | Fortified plant-based milk Sunflower seeds | Calcium from fortified plant-based milk and vitamin D from sunflower seeds support bone health. |
Omega-3 and antioxidants | Flaxseed Berries, chia seeds Kiwi | Omega-3 fatty acids from flax and chia seeds combined with antioxidants from berries and kiwi for improved heart health. |
Zinc and phytic acid breakdown | Chickpeas Garlic, pumpkin seeds Lemon juice | Garlic and lemon juice can help break down the phytic acid in chickpeas and pumpkin seeds and improve zinc absorption. |
Magnesium and vitamin B6 | Bananas Almonds, avocado Spinach | Vitamin B6 from bananas and avocado improves magnesium absorption from almonds and spinach. |
Iodine and selenium | Seaweed Brazil nuts | Iodine from seaweed and selenium from Brazil nuts support thyroid function. |
Folic acid and fibre | Broccoli Wholemeal pasta, spinach Chickpeas | Folic acid from broccoli and spinach in combination with fibre from wholemeal pasta and chickpeas for healthy digestion. |
Vitamin A and healthy fats | Carrots Olive oil, sweet potatoes Avocado | Healthy fats from olive oil and avocado improve the absorption of fat-soluble vitamin A from carrots and sweet potatoes. |
Combining iron-rich plant foods with vitamin C-rich foods helps to increase the bioavailability of iron, as vitamin C supports the conversion of non-heme iron into a more absorbable form. Similarly, combining different plant-based protein sources ensures that the body receives all the necessary amino acids required for muscle building and tissue repair.
The combination of calcium and vitamin D, as found in fortified plant-based milk and sunflower seeds, promotes calcium absorption, which is crucial for bone health. Omega-3 fatty acids and antioxidants, found in foods such as flaxseed and berries, support heart health and provide anti-inflammatory benefits.
Zinc, an important nutrient for the immune system, can be better absorbed by eating chickpeas and pumpkin seeds in combination with garlic and lemon juice, as these foods break down phytic acid, which inhibits zinc absorption. Magnesium and vitamin B6 work together to support muscle function and promote energy production.
By strategically combining foods, vegetarians can ensure that they absorb all the necessary nutrients efficiently and maintain a balanced, healthy diet.
Regular blood tests
Regular blood tests are important to recognise and correct possible nutrient deficiencies at an early stage. Vegetarians in particular should have their vitamin B12, iron, vitamin D and omega-3 levels checked regularly. This enables targeted and needs-based supplementation. In general, annual blood tests are sufficient for most people to monitor their general health. Vegetarians, especially those who take certain supplements or follow a stricter diet such as veganism, can have specific nutrients such as vitamin B12, iron, vitamin D and omega-3 fatty acids tested every six months to once a year. If there are existing health problems or symptoms of nutrient deficiencies, the frequency of testing should be adjusted in consultation with a doctor.
Advice from specialists
It can be helpful to seek advice from nutritionists or doctors to ensure that the diet is balanced and all nutritional requirements are met. Specialists can make personalised recommendations and help with the selection of suitable nutritional supplements.
Conscious food choices
Vegetarians should be aware of their food choices and preferably choose fresh, unprocessed products. Processed foods can often contain fewer nutrients and more unhealthy additives. A varied and wholesome plant-based diet can help to meet nutrient requirements and promote health.
Conclusion
A balanced vegetarian diet can offer numerous health benefits, provided it is well planned and takes into account the intake of all essential nutrients. By choosing a diverse range of nutrient-rich plant foods and using targeted supplements, vegetarians can ensure that they do not suffer any deficiency symptoms. Regularly checking the nutrient status and adjusting the diet or supplementation as required are crucial. Food supplements for vegetarians play an important role in ensuring optimal health and vitality.
