Strengthens bones even in the womb: researchers have discovered which vitamin is crucial during pregnancy.

A recent study conducted by the University of Southampton and Southampton University Hospital revealed that children whose mothers took vitamin D supplements during pregnancy had stronger bone structures by the age of seven. These findings may assist scientists and healthcare professionals in developing future strategies to enhance the health of millions of children even before their birth, as reported by ScienceDaily.

The research, published in the American Journal of Clinical Nutrition, involved scanning the bone density of over 1,000 children and showed that those who received higher levels of vitamin D in utero had bones with greater calcium content and mineral density compared to children whose mothers took a placebo.

Vitamin D is essential for bone health as it aids the body in absorbing calcium — a mineral crucial for the strength and density of bones. It is considered extremely important for bone health, according to Rosie Carr, a dietitian from the Second Nature healthy eating program. Carr states that the role of vitamin D in calcium absorption supports the bone remodeling process — a natural cycle of bone tissue renewal.

Without adequate vitamin D, merely consuming calcium may not be sufficient to maintain strong bones. The researchers’ findings align with the existing knowledge about the role of vitamin D in bone health, particularly in children and older adults who are prone to conditions such as osteoporosis and rickets.

A deficiency can lead to various health issues, often affecting muscles and bones. Consultant rheumatologist Dr. Clare Gorman notes that early symptoms of deficiency include muscle aches and bone pain. If not addressed, the deficiency can result in muscle weakness, often in the hips, which can impair mobility. Severe or prolonged vitamin D deficiency is associated with osteoporosis — a condition characterized by brittle, fragile bones and an increased risk of fractures.

In young children, a deficiency can lead to rickets — a disease that causes weak bones and skeletal deformities. Certain populations are more vulnerable to vitamin D deficiency, particularly older adults whose mobility and access to sunlight may be limited. Carr explains that decreased physical activity, reduced appetite, and lower nutrient intake all contribute to a higher likelihood of deficiency among the elderly. However, vitamin D deficiency can occur in individuals of any age if they have limited sun exposure, poor diets, or low levels of physical activity.

As for dietary sources, vitamin D can be found in several foods. Eggs, for instance, are a valuable source, providing protein along with vitamin D. Mushrooms also contain vitamin D, especially when exposed to sunlight, as explained by Jenna Hope, a registered dietitian. Other sources include red meat and fatty fish, such as salmon, which not only contain vitamin D but also beneficial proteins that support bone health. Some foods, like butter, fruit juices, and cereals, are also fortified with vitamin D to help maintain adequate levels. In addition to diet, experts highlight the connection between sunlight and vitamin D production, as our bodies also synthesize it in response to ultraviolet rays. This synthesis is particularly important in countries with limited sunlight during the winter months, where diet and supplements become vital to maintaining healthy levels of this key vitamin.
