How good is VIT classified

Vitamin D: product test rehabilitates drugs

The testers bought and rated five over-the-counter medicines from pharmacies and 16 food supplements (NEM) from pharmacies, drugstores and food retailers (LEH). Professor Dr. Manfred Schubert-Zsilavecz from the Institute for Pharmaceutical Chemistry at the University of Frankfurt aside. The following criteria were used for testing: Has the effectiveness or benefit been proven? Are the corresponding warning notices included in the package insert? Are there questionable or controversial auxiliaries or ingredients? Have the maximum quantities recommended by the Federal Institute for Risk Assessment (BfR) been observed?

This year the authorities raised the recommended maximum amount for vitamin D to 20 µg or 800 I.U. Previously, the upper limit was 5 µg. According to the expert commission, the preparations could still be classified as nutritional supplements up to a daily dose of 20 µg, higher doses are to be regarded as medicinal products. The European Food Authority (EFSA) sets the upper limit at 100 µg for the total intake.

All drugs in the test contain 1000 I.E vitamin D3 and are given the green light. Dekristol (Mibe), Vigantol (Merck), Vitagamma (Wörwag), Vitamin D Sandoz (Hexal) are rated "very good". Warentest finds it positive that all drug package inserts warn of metabolic disorders such as hypercalcaemia or hypercalciuria.
