Vitamin B12 can be taken at any time of the day or night. However, to ensure optimal active absorption into the body, the preparation should ideally be taken on an empty stomach or between meals.

An overdose of vitamin C is generally possible, but relatively rare and in most cases not serious, since excess vitamin C is usually excreted in the urine. The body can only absorb and use a limited amount of vitamin C. Only persons with impaired renal function or metabolic disease should exercise caution with vitamin C. In such a case, consult a medical professional. In general, it is advisable not to exceed the recommended daily dose of the product when taking vitamin preparations.

Solarium visits are not a recommended alternative to stimulate the body’s own vitamin D production. A specific wavelength in the UV-B range is required for vitamin D formation. However, most solaria mainly use UVA radiation, which achieves a good tanning effect, but can also lead to chronic skin damage, such as premature skin ageing.

Among our most common foods, rosehips, sea buckthorn, blackcurrants, red pepper, broccoli, kale and Brussels sprouts contain the most vitamin C.

Vitamin B12 is generally well tolerated, even in high amounts.

Vitamin E is a powerful antioxidant that protects cells from free radical damage. It supports skin health, promotes the immune function, protects the eyes, contributes to cardiovascular health and plays a role in the regulation of the hormone balance. It also helps to stabilise the cell membranes and support general cell function.

Considering the vitamin D status in Europe, large parts of the population can benefit from vitamin D supplements. There are also several groups that should pay particular attention to their vitamin D intake. These include, for example, older people, because the synthesis performance of the skin decreases by up to 50% with age. People who rarely get into the sun at the right time due to long-term indisposition or unfavorable working hours also benefit from supplements. Pregnant and breastfeeding women, as well as infants in the first year of life who must be protected from direct sunlight, also have an increased need. A blood analysis can quickly and easily detect a vitamin D deficiency!

Vitamin C and ascorbic acid are not exactly the same. Chemically, vitamin C is L-ascorbic acid. In addition, however, there are other ascorbic acids, not all of which have a vitamin C effect, such as D-ascorbic acid. Vitamin C is therefore an ascorbic acid, but not every ascorbic acid is also vitamin C.

Yes, the vitamin C requirement is usually easily met through food as long as a balanced and varied diet is followed. Consuming vitamin-rich foods such as fresh fruit and vegetables every day allows most healthy people to meet their needs for vitamin C. According to the German Nutrition Society (DGE), the recommended daily dose for adults is approximately 100 milligrams per day, which can be easily achieved by consuming, for example, a large orange or a portion of pepper. However, it is important to note that the vitamin C requirement may be increased in certain life situations, such as pregnancy, breastfeeding, intensive physical activity or in smokers. In such cases, particular care should be taken to consume sufficient vitamin C-rich foods or, if necessary, to use nutritional supplements to cover the increased need and prevent a deficiency.
