Nutritional deficiencies in Vitamin D and B12 identified as widespread concerns

Nutritional deficiencies, particularly regarding Vitamin D and Vitamin B12, are widespread issues. According to the German Nutrition Society (DGE), nearly 60 percent of Germans do not reach the recommended Vitamin D blood levels. High-risk groups for Vitamin D deficiency include the elderly, individuals with darker skin due to reduced UV-B absorption, those who stay indoors frequently, and infants.

Vitamin B12 deficiency is also common, affecting approximately one in ten people in Germany and one in four people over the age of 65. Symptoms of B12 deficiency, such as fatigue, pale skin, and weakness, can overlap with iron deficiency. B12 is essential for cell division, DNA synthesis, and blood formation. Because it is primarily found in animal products, the DGE recommends supplementation for vegetarians and vegans.

Daily Vitamin B12 requirements vary by age and life stage. For adults aged 13 to 65, the recommended daily intake is 4.0 µg, while pregnant and breastfeeding women require higher amounts (4.5 µg and 5.5 µg, respectively). Factors such as alcohol consumption and the use of contraceptive pills can also increase the body's demand for the vitamin.
