Vitamin B

These Foods Are the Best Sources of Vitamin B

Vitamin B is a group of water-soluble vitamins that have been shown to have a several important health benefits. Vitamins B1, B2, B3, B5, B6, B10, B11 and B12 are generally grouped under the name of group B vitamins. We show you the functions of B vitamins and which foods contain the most vitamin B.

How vitamin B helps us

B vitamins are one of the most important vitamin groups for humans. Our body needs vitamin B for the brain, the nervous system and the muscles, among other things, but also many different metabolic processes as well as strong skin and plump hair. Most B vitamins can be covered by food, e.g. whole grain products. Only vegetarians and vegans need to pay attention to the supply of vitamin B12 (cobalamin), even though vitamin B12 and vitamin B3 can be stored in the body. The other B vitamins are excreted by the body when the daily dose is exceeded.

They are somewhat more expensive, but with around 15 micrograms of vitamin B12 per 100 grams, they are an absolute supplier of vital nutrients. With 7 milligrams of iron, 100 grams of mussels cover half of the recommended daily requirement.

Lamb's lettuce

2. Lamb’s lettuce
It is harvested from October to April and is a surprising vitamin bomb: Lamb’s lettuce contains 145 micrograms of folic acid per 100 grams as well as 380 micrograms of vitamin B3, 250 micrograms of B5 and 200 micrograms of B6.

Tip: Consume quickly after purchase, otherwise precious vitamins are lost.


3. Chicken
It is low in fat, high in protein and contains about 0.1 milligrams of vitamin B1, 0.2 milligrams of vitamin B2 and 0.3 milligrams of vitamin B6. With 23 grams of protein per 100 grams, it saturates for a long time and contributes to muscle maintenance.

Sesame Seeds

4. Sesame seeds
Sesame seeds are very rich in vitamin B, as 100 grams contain 0.79 milligrams of vitamin B6, 0.97 micrograms of folic acid, 0.25 milligrams of vitamin B2 and 1.41 milligrams of vitamin B5. They are very rich in fiber, but also very high in calories due to their high fat content.

Kale Salad

5. Kale
It provides about 1000 micrograms of vitamin B5 and 47 micrograms of folic acid per 100 grams. At the same time, kale has 4.3 grams of protein per 100 grams, which makes it not only a vitamin bomb but also one of the most protein-rich cabbages. It is in season from November to February and is often prepared with Mettenden and Kasseler during the Christmas season.

When the amino acid is present in elevated concentrations in the body, serious illnesses can result. Elevated homocysteine levels are caused by folic acid and vitamin B-12 deficiency, excessive coffee consumption, obesity, nicotine, lack of exercise and excessive alcohol consumption.

Mackerel Fish

8. Mackerel
In 100 grams of fatty sea fish, there are 0.31 milligrams of vitamin B6, 0.43 milligrams of vitamin B2 and 7.3 micrograms of vitamin B12. But also 0.3 to 1.6 grams of omega-3 fatty acids, which keep the cardiovascular system going and weaken chronic inflammation, as well as keep the brain fit.

Veal Fillet

9. Veal
It is very lean and contains 0.56 milligrams of vitamin B6 per 100 grams, as well as 0.26 milligrams of vitamin B2. Tip: White to pale pink meat is usually of inferior quality. This is because the calves are fed milk and straw instead of hay and grass.

19. Mussels
Not only are they super tasty, but they also contain 14 micrograms of vitamin B12 per 100 grams. They also contain 4.2 grams of iron, which we need for optimal blood formation.


20. Cauliflower

Cauliflower is a highly underrated vegetable. Besides 125 micrograms of folic acid per 100 grams, it contains a lot of vitamin C and minerals. If it has brown spots, it has been stored incorrectly and has already lost vitamins as a result. To make it last longer, simply remove the leaves and place them in the vegetable compartment of the refrigerator. There it will stay fresh for several days.

Particularly many nutrients are retained when the potato is prepared as jacket potatoes, fried potatoes or in the oven.


25. Mushrooms
Mushrooms are low in calories due to their high water content. Nevertheless, they are rich in vitamins and nutrients. In them, there is especially a lot of vitamin B3 (5200 micrograms per 100 grams), but also a lot of vitamin B5. Vitamins B1, B2 and B6 are present in mushrooms in smaller quantities. If they are prepared gently, many of the vitamins are preserved!

How much vitamin B do I need?

There are a total of eight different B vitamins: B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folic acid) and vitamin B12 (cobalamin). They all belong to the group of water-soluble vitamins, which is why the body cannot store them – except for vitamin B2 and vitamin B12 – and excretes them in the urine. Therefore, it is important to cover the daily requirement with food or, if necessary, with food supplements.

The daily requirement for women and men is as follows:

Recommended daily requirement of vitamin B

Vitamin B Women Men
B1 1,0 µg 1,1 – 1,3 µg
B2 1,0 – 1,1 mg 1,3 – 1,4 mg
B3 11- 13 mg 14 – 16 mg
B5 6 mg 6 mg
B6 1,4 – 1,6 mg 1,2 mg
B7 30 – 60 µg 30 – 60 µg
B9 300 µg 300 µg
B12 4,0 µg 4,0 µg
Vitamin B1 (thiamine)

Vitamin B1 is an important component in the metabolisation of carbohydrates and has a high influence on the nervous system. For example, it determines how well the muscles react to impulses.

Vitamin B1 deficiency:

Symptoms of a vitamin B1 deficiency can include indigestion and lack of appetite. Tiredness and depressive moods are also indications of an undersupply of vitamin B1.

Vitamin B2 (riboflavin)

Vitamin B2 ensures that the brain is supplied with glucose. It also maintains the respiratory system and protects the red blood cells.

Vitamin B2 deficiency:

A deficiency manifests itself, among other things, in torn corners of the mouth, as well as inflammation of the oral mucosa and inflammatory skin changes. A vitamin B2 deficiency can promote cataracts.

Vitamin B3 (niacin)

Vitamin B3 is involved in numerous metabolic processes in the body, e.g. the production of fatty acids.

Vitamin B3 deficiency:

A deficiency is very rare in our latitudes. However, should it occur, a deficiency manifests itself in loss of appetite and general weakness. A permanent undersupply of niacin can trigger the disease pellagra, which can manifest itself in dermatitis, diarrhoea and dementia.

Vitamin B5 (pantothenic acid)

Vitamin B helps the body convert food into usable energy. It is involved in producing important substances such as long-chain fatty acid, provitamin D, bile acid, cholesterol and certain amino acids. Pantothenic acid has proved particularly useful in skin and hair care. Together with vitamin B7, it ensures full hair and clearer skin.

Vitamin B5 deficiency:

A deficiency only occurs in cases of severe malnutrition and alcohol abuse. It manifests itself as a painful burning and tingling sensation in the feet.

Vitamin B6 (pyridoxine)

Vitamin B6 or pyridoxine helps in the production of serotonin, dopamine, histamine and haemoglobin, the pigment of red blood cells. It also supports fat metabolism and regulates the immune system. Vitamin B6 is also said to be effective for morning sickness and premenstrual syndrome (PMS).

Vitamin B6 deficiency:

Symptoms of vitamin B6 deficiency include acne, inflamed corners of the mouth, fatigue and sensitivity to light.

Vitamin B7 (biotin)

Vitamin B7 is mainly known for its supportive effect on hair growth. It also strengthens finger and toenails, supports energy metabolism, normalises cholesterol levels and blood sugar levels and prevents gestational diabetes.

Vitamin B7 deficiency:

Classic symptoms of a biotin deficiency are hair loss, scaly, red skin rash, cracked corners of the mouth, depression, nausea, weakness and listlessness.

Vitamin B9 (folic acid)

Vitamin B9 affects cell division in the bone marrow and helps in the formation of new blood cells. Folic acid is especially recommended for pregnant women, as a deficiency can lead to malformations of the central nervous system such as open back (spina bifida) in the unborn child.

Vitamin B9 deficiency:

Since the vitamin can only be stored in small amounts by the body, a deficiency is quite common. In pregnant women, a folic acid deficiency can favour premature births. A deficiency can also influence cardiovascular diseases.

Vitamin B12 (cobalamin)

Vitamin B12 – also known as cobalamin – is involved in the development of nerve cells in the spinal cord. It affects many reactions in protein and nucleic acid metabolism and supports the absorption of folic acid into the red blood cells.

Vitamin B12 deficiency:

Symptoms of vitamin B12 deficiency include cell division disorders in the skin and mucous membranes, muscle weakness, fatigue, poor concentration and memory, headaches, migraines, depression, hair loss, allergies and degeneration of the optic nerve. The doctor can recognise a B12 deficiency from your blood values, e.g. from larger amounts of the amino acid homocysteine.
