Human migration patterns connected to vitamin D deficiencies today

A new study in the Oxford Economic Papers finds that migration flows the last 500 years from high sunlight regions to low sunlight regions influence contemporary health outcomes in destination countries. The researchers here noted that people’s ability to synthesize vitamin D from sunlight declines with skin pigmentation, and that vitamin D deficiency is directly […]

Vitamin boosts essential synthetic chemistry — ScienceDaily

Inspired by light-sensing bacteria that thrive near hot oceanic vents, synthetic chemists at Rice University have found a mild method to make valuable hydrocarbons known as olefins, or alkenes. Like the bacteria, the researchers use vitamin B12, eliminating harsh chemicals typically needed to make precursor molecules essential to the manufacture of drugs and agrochemicals. The […]

Effect of vitamin B12 injection on vocal performance of professional singers

New insight into a placental gene pathway and its association with vitamin D — ScienceDaily

According to the World Health Organization, preeclampsia affects between 2% to 8% of pregnancies. It can cause serious, sometimes fatal, complications in the mother and child. Among other risk factors, such as obesity and diabetes, vitamin D deficiency during pregnancy has been associated with an increased risk of preeclampsia. In an article in Pregnancy Hypertension, […]

Vitamin D lessens symptoms of severe eczema in children

Vitamin D supplementation eased the symptoms experienced by children with severe atopic dermatitis, or eczema, in a recent randomized controlled trial published in Pharmacology Research & Perspectives. Investigators reported on the results of 86 patients with the inflammatory skin condition who completed the trial and received either oral daily vitamin D or placebo, in addition […]

Does vitamin D protect against COVID-19?

In the absence of a COVID-19 cure or vaccine, scientists are investigating whether vitamin D can reduce the risk of COVID-19 infection or the severity of the disease. Indeed, the idea of taking a vitamin to ward off COVID-19 infection certainly is appealing. But although some recent studies have suggested a link between low vitamin […]

Vitamin B3 protects skin cells from the effects of UV exposure, new research finds

LUGANO, 31 October, 2020 – Research presented today at EADV’s 29th Congress, EADV Virtual, shows hope that a form of vitamin B3 could protect skin cells from the effects of ultraviolet (UV) exposure: the main risk factor for non-melanoma skin cancers (1). Researchers in Italy isolated cells (human primary keratinocytes) from the skin of patients […]
