Vitamin D deficiency and health impacts

Overview

Vitamin D deficiency is identified as a global health concern linked to modern lifestyles and limited sun exposure. Low levels of 25-hydroxyvitamin D can compromise calcium and phosphorus absorption, leading to musculoskeletal issues such as rickets in children and osteomalacia in adults. Physical symptoms include muscle weakness and deep bone pain.

Health organizations, including the German Nutrition Society (DGE) and the European Food Safety Authority (EFSA), utilize serum concentration metrics to assess adequacy. While 50 nmol/l (20 ng/ml) is considered an adequate orientation value, levels between 30 and 50 nmol/l are often classified as suboptimal. A deficiency is generally identified when levels fall below 30 nmol/l (12 ng/ml), increasing risks for osteoporosis and other conditions. The Robert Koch Institute (RKI) notes that these serum levels fluctuate significantly, particularly during winter months.
