Vitamin D – the sunshine vitamin in drop form Optimally bioavailable and stable ✓ 800 IU (20 µg) vitamin D3 from Germany in pharmacopoeial quality ✓ Good for bones, muscles and the immune system* ✓ Expertise + experience: first vitamin D3 oil in German pharmacies (since 2013) ✓ Vitamin D oil for the whole family – also for children and infants ✓ Very good price-dose ratio: 640 drops, vegetarian 20 ml (640 servings) Only 12% have good vitamin D3 levels, in winter it is less than 5% Diet contributes little to vitamin D supply; UVB sunlight is crucial for the skin's own synthesis. A deficiency is particularly common in winter, but factors such as sun protection or a dark skin type can also inhibit vitamin D synthesis in summer. Studies show that endogenous production is often insufficient, even in summer: Only 12% of the German population achieves the annual average vitamin D level of over 75 nmol/l (1,2) recommended by leading scientists, and in winter, even less than 5%. The lower limit of at least 50 nmol/l recommended by the German Nutrition Society (DGE) is achieved year-round by only 38% of Germans.(3) Experts also disagree on the correct intake recommendations. In fact, this depends on many factors: baseline value, age, weight, sun exposure, skin color, etc. The DGE recommends a serum level of at least 50 nmol/l and 800 IU (20 µg) of vitamin D daily (from the age of 2, if endogenous synthesis is lacking). The renowned American Geriatrics Society recommends that all people aged 70 and over take 4000 IU (100 μg) of vitamin D daily (from all sources) to maintain a good serum level of at least 75 nmol/L. This corresponds to the daily intake established by the European Food Safety Authority (EFSA) as safe (tolerable) for people aged 11 and over. (1)Holick et al.

Who should pay particular attention to their vitamin D levels? • Everyone in months with low UV radiation (October to March) • People who spend most of their time indoors or who cover their skin • Users of sunscreen (SPF 10 reduces vitamin D production by 90%) • People with dark skin • Pregnant women, breastfeeding women, babies and small children • Women in/after menopause • Overweight people • Seniors A vitamin D blood test (at the doctor, in the pharmacy or a self-test) can provide clarity.

MCT oil for optimal protection and better absorption To improve the absorption of fat-soluble vitamin D3, we use a high-quality MCT oil that is produced in Europe from coconut oil. Together with the natural vitamin E family (tocopherols), this oil protects sensitive fat-soluble vitamins and optimizes their absorption. The best interaction: the ideal partners for vitamin D Not only vitamin D3 contributes to the maintenance of normal bones, but also vitamin K2. Both work synergistically and are best taken in combination, as in Dr. Jacob's Vitamin D3K2 Oil, Dr. Dr. Jacob's Vitamin D3K2 Oil Forte, Dr. Jacob's Vitamin K2D3 Oil (for increased vitamin K2 requirements), and Dr. Jacob's Vitamin DEKA Oil (with vitamins A and E as natural tocopherols). Calcium metabolism interacts closely with magnesium and potassium. Magnesium supports the maintenance of normal bones and the normal function of nerves and muscles. Potassium contributes to the normal function of muscles and the nervous system, as well as to the maintenance of normal blood pressure. According to the National Nutrition Survey (NVS2), a deficiency in these minerals is common (4). Therefore, vitamins D3 and K2 are best combined with the right minerals, such as those contained in Dr. Jacob's Base Powder (4) National Nutrition Survey 2 (MRI 2008).
