The German Society for Paediatric and Adolescent Medicine (DGKJ) recommends not only supplying bottle-fed babies, but also breastfed babies with 400 – 500 IU of additional vitamin D daily.

Vitamin D drops are easy for anyone to take and automatically provide the body with fat (oil), which it needs as a transport medium to absorb the fat-soluble vitamin well. Those who prefer tablets or capsules should choose products that are as free as possible from additives and take the vitamin with a fat-containing meal.

Selenium capsules and drops can help to provide the body with extra selenium in a targeted way.

Yes, biotin is just another term for vitamin H.

No, NADH is not vitamin B3 directly, but the biologically active form of it. Vitamin B3, also known as niacin, is converted in the body to NAD (nicotinamide adenine dinucleotide), which is then reduced to NADH (nicotinamide adenine dinucleotide hydride). NADH is thus a coenzyme derived from vitamin B3 and plays a central role in the energy metabolism of the cells. While vitamin B3 is the precursor, NADH performs the function of energy production in the mitochondria.

Vitamin D and vitamin B12 can be taken together without any problems. The two vitamins do not interfere with each other's absorption or further metabolism.

Whether vitamin tablets or capsules make sense depends on various factors, including diet, health status and individual needs. When vitamin tablets or capsules may be useful: Deficiencies: if a vitamin deficiency is diagnosed, vitamin supplements may be necessary to compensate for this. Specific stages of life: pregnant women, breastfeeding mothers, elderly people or children in growth phases may have an increased need for certain vitamins Restricted nutrition: people who eat vegan or vegetarian diets may be at higher risk of vitamin deficiencies (such as B12). Health conditions: certain diseases or medications may affect the absorption and need for vitamins, which may make supplementation recommended. Increased physical activity: athletes or people with very active lifestyles may have an increased need for certain vitamins. Multivitamin preparations such as the multi-spectrum 24/7® from BIOGENA in particular can represent a valuable addition to a balanced diet. It contains all the vitamins in one capsule. 

‘Vitamin- B12 robbers’ are substances, factors or lifestyle habits that impair the absorption or metabolism of vitamin B12 in the body. These include, for example, gastrointestinal diseases, medications such as those used to treat diabetes, alcohol or a purely plant-based diet.

Vitamin D is found in appreciable amounts in a small selection of foods. The frontrunners include fatty fish such as wild salmon, herring and eel, as well as liver and cod liver oil. Smaller amounts of vitamin D are found in egg yolks, liver and some wild mushrooms, such as porcini or chanterelles.

Vitamin C is not only a support for our immune system and general energy. Its role in collagen formation also contributes to the normal functioning of the skin, blood vessels, teeth, gums, cartilage and bones. It helps to protect the cells from oxidative stress and to recycle consumed vitamin E.
