Vitamin D health and deficiency guidance

Overview

Health guidance and research highlight the importance of maintaining vitamin D levels, particularly during winter months when reduced sunlight limits natural synthesis. Vitamin D is essential for calcium absorption, bone health, immune response, muscle function, and mood regulation.

Deficiency can be caused by seasonal changes, poor diet, aging, obesity, and physical barriers like window glass that filter UVB rays. Consequences of a deficit include fatigue, muscle or bone pain, and increased respiratory infections. Because over 90 percent of the body’s vitamin D requirement is typically met through natural sunlight, insufficient UV exposure can impair the intestines’ ability to absorb calcium.

Low levels are specifically linked to decreased bone mass, osteoporosis, and an increased risk of fractures. In adults, severe deficiency can lead to osteomalacia, a condition where bones become soft and weak, causing persistent pain. In children, this deficiency manifests as rickets, which can seriously impact skeletal development.

To mitigate these risks, experts recommend a combination of dietary intake from fatty fish like salmon and mackerel or fortified products like milk and orange juice, moderate sun exposure, and oral supplementation. However, medical professionals caution against excessive supplementation, as overconsumption can cause calcium to deposit in the kidneys, leading to stones, or accumulate in soft tissues such as the heart, lungs, and blood vessels.
