A new study from the University of Otago found that high-dose monthly vitamin D supplements for breastfeeding mothers can significantly increase their babies' vitamin D levels. This is particularly important as exclusive breastfeeding increases the risk of infant vitamin D deficiency, leading to conditions like rickets.
A Swedish study of over 2 million children found that those born in spring had a higher risk of developing coeliac disease, especially before age 2. The risk was also higher among girls and in the south of the country where sunlight is more intense, suggesting possible links to viral infections and vitamin D.
A new study found that women who stopped using estrogen-containing contraceptives had average vitamin D levels, while current users tended to have higher levels. Women trying to conceive should take action to maintain adequate vitamin D levels before and during pregnancy.

Strongest effects were seen in reducing falls and fractures among the elderly. Moderate supplementation is unlikely to cause harm but will not lead to significant health benefits.
A study by Cincinnati Children's Hospital Medical Center found that a high percentage of children and young adults with migraines have mild deficiencies in vitamins D, riboflavin, and coenzyme Q10. These deficiencies may be involved in migraine development, but it is unclear whether supplementation would help prevent the condition.
A study published in Scientific Reports found that vitamin D lowers the risk of developing hyperglycaemia when taken with atypical antipsychotics like quetiapine. The researchers also confirmed this finding using mouse tests, revealing that vitamin D defends against the insulin-lowering effects of quetiapine.

The research found that increased sunlight exposure, which is where Americans get most of their vitamin D, reduces the risk of asthma in children.
A Finnish study found that vegans often follow an unbalanced diet, leading to deficiencies in vitamin B12, D, selenium, iodine, and essential fatty acids. Vegans tend to use recommended supplements, such as calcium-fortified drinks and vitamin D supplements, but may need closer monitoring of their nutrient intake.
A study of 413 patients with symptomatic knee osteoarthritis found that vitamin D supplementation did not slow cartilage loss or reduce knee pain over 2 years. Vitamin D levels increased, but no significant benefits were seen.

A new study by Northwestern University research found that low levels of vitamin D are associated with aggressive prostate cancer in men. Men with dark skin or limited sun exposure should get their vitamin D levels checked and supplement if necessary to reduce the risk of aggressive prostate cancer.
A randomized controlled trial found that vitamin D supplements during pregnancy have no significant effect on the bone density of babies. However, further analysis suggests that supplementation may counteract the seasonal drop in vitamin D levels caused by lack of sunlight, potentially improving bone health in winter-born babies.
A new study found that vitamin D supplementation during pregnancy can increase bone mass in babies born during the winter months, potentially leading to stronger bones and a reduced risk of osteoporosis. The supplement showed no difference in overall bone mass but had a positive impact on children born during the colder months.
