Practical guide

Vitamins A, B, C, D, E, K: what does each one do?

Behind the letters A, B, C, D, E and K (often shortened to “ABCDEK”) are thirteen vitamins: vitamin A, the eight B vitamins, then vitamins C, D, E and K. The body needs them in very small amounts, but cannot make them, or not enough of them.

They are classified into two families according to their solubility. The roles of each are governed by official European Union claims.

13 vitamins

A, B1, B2, B3, B5, B6, B8, B9, B12, C, D, E and K.

Fat-soluble: A, D, E, K

They dissolve in fats and are stored by the body.

Water-soluble: B and C

They dissolve in water and must be supplied regularly.

Fat-soluble vitamins

Vitamins A, D, E and K: sources and roles

These four vitamins are better absorbed with a little fat, hence the oil drops. RI stands for the daily reference intake for an adult.

Vitamin A (RI: 800 µg)

Found in liver, eggs and butter; carrots and orange vegetables provide beta-carotene. It contributes to the maintenance of normal vision and normal skin, and to the normal function of the immune system.

Vitamin D (RI: 5 µg)

Produced by the skin when exposed to the sun, and found in oily fish. It contributes to the normal function of the immune system, to the maintenance of normal bones and to normal absorption and utilisation of calcium and phosphorus.

Vitamin E (RI: 12 mg)

Provided by vegetable oils, almonds and seeds. It contributes to the protection of cells from oxidative stress.

Vitamin K (RI: 75 µg)

K1 in green leafy vegetables, K2 in fermented foods. It contributes to the maintenance of normal bones and to normal blood clotting.

Water-soluble vitamins

B vitamins and vitamin C

The eight B vitamins are found in wholegrain cereals, pulses, eggs, meat and fish. Reference intakes: B1 1.1 mg, B2 1.4 mg, B3 16 mg, B5 6 mg, B6 1.4 mg, B8 (biotin) 50 µg, B9 200 µg and B12 2.5 µg.

Vitamin C (RI: 80 mg) is found in fresh fruit and vegetables. It contributes to the normal function of the immune system, to the reduction of tiredness and fatigue and to the protection of cells from oxidative stress, and increases iron absorption.

Vitamin B1

It contributes to the normal function of the heart and to normal psychological function.

Vitamin B2

Riboflavin, found in dairy products, eggs and almonds.

Read the vitamin B2 guide →

Vitamin B3

Niacin, provided by meat, fish and wholegrain cereals.

Read the vitamin B3 guide →

Vitamin B5

Pantothenic acid, very widespread in the diet.

Read the vitamin B5 guide →

Vitamin B6

It contributes to the reduction of tiredness and fatigue and to the regulation of hormonal activity.

Read the vitamin B6 guide →

Biotin (B8)

It contributes to the maintenance of normal hair and normal skin.

Forms

Active forms, D3, K2 MK-7: what are we talking about?

For B12, methylcobalamin is a so-called active form. For B9, 5-MTHF (methylated folate) is the active form, whereas folic acid has to be converted before it can be used.

For vitamin D, D3 (cholecalciferol) is the form produced by the skin. Vitamin K2 MK-7 is a form that remains in the body for a long time. Camu-camu is an Amazonian berry naturally rich in vitamin C.

Frequently asked questions

FAQ on vitamins A, B, C, D, E, K

What does ABCDEK mean?

It is the abbreviation for vitamins A, B, C, D, E and K, i.e. the thirteen known vitamins, since “B” covers eight different vitamins.

Can vitamins A, D, E and K be taken together?

Yes, some formulas combine them, such as our Vitamine DEKA, which brings together D3, K2 MK-7, A and E in coconut MCT oil. Preferably take them with a meal.

Should I take vitamin D in summer?

Its production depends on how much your skin is actually exposed to the sun, the time of day, the season and the use of sunscreen. A blood test prescribed by your doctor can help assess your status.

Does a plant-based diet provide all the vitamins?

Most of them, but not vitamin B12, which is absent from plants. It is found in animal products, fortified foods and supplements.

Can a vitamin supplement replace food?

No. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. During pregnancy and breastfeeding, ask your doctor for advice.
