The study concludes that vitamin D supplements probably provide little to no health benefit, contradicting previous observational studies that linked deficiency to poor health.
A new study published in Molecular Biology and Evolution found that calcium absorption was not the primary reason for the evolution of milk tolerance in Europeans. The researchers discovered that fermented milk products, such as yoghurt and cheese, played a significant role in the rapid emergence of lactase persistence.
A new study published in Molecular Biology and Evolution suggests that strong natural selection acted on lactase persistence in Iberia over the last 7,000 years. The 'calcium assimilation hypothesis' is challenged as sunlight in Iberia allows for vitamin D synthesis, making calcium deficiency less of a concern.

The review highlights the need for further research and public health measures to improve vitamin D status, particularly in high-risk groups su...
A recent study published in Critical Reviews in Oncology/Hematology found that calcium and vitamin D supplements do not prevent bone mineral density loss in women undergoing breast cancer treatment. Women with breast cancer experience a higher rate of bone loss than healthy counterparts, increasing their risk of fractures.

Patients from neurosurgical intensive care units often experience vitamin D deficiency, linked to impaired immunological status. Vitamin D supplementation has shown promise in improving patient immunological status and reducing infections.
Researchers at Berkeley Lab's Advanced Light Source found that vitamin D deficiency not only reduces bone mineralization but also induces premature aging of existing bone. This accelerates the risk of fractures in patients with vitamin D deficiency.
A study published in JAMA found that low vitamin D blood levels are associated with a greater risk of heart disease in whites and Chinese populations, but not in blacks and Hispanics. The researchers suggest that genetic factors may play a role in the varying associations between vitamin D levels and heart disease across different raci...
A large multiethnic population study found that low vitamin D levels are associated with increased coronary heart disease events among white and Chinese participants but not black or Hispanic participants. The findings suggest that the risks and benefits of vitamin D supplementation should be evaluated carefully across race and ethnicity.
