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.

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.

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

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. 

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.

The synergistic effects of vitamins D3 and K2 are the focus of current science and research, which has led to the development of the micronutrient preparation Biogena Vitamin D3 & K2. Vitamin K contributes to normal blood clotting, helps maintain normal bones just like vitamin D and is therefore a sensible addition to vitamin D supplementation.

Vitamin C is a heat sensitive vitamin, so long cooking times at high temperatures should be avoided in fruit and vegetables.

A lot of vitamin C is found in fresh fruit and vegetables. Among the foods we usually use, rosehips and sea buckthorn, blackcurrants, red pepper and broccoli as well as kale and Brussels sprouts are considered top vitamin C suppliers.
