vitamin deficiencies

Researchers uncover innovative natural approaches to fine-tune immunity from vaccination.

A large trial adds to a growing list of conditions once thought to be helped by vitamin D supplementation.

Mice with low vitamin D had exaggerated craving for opioids and felt the drugs’ effects more strongly—results supported in part by human medical records—suggesting that supplements should be explored as treatments for opioid use disorders.

In clinical studies worldwide, researchers are testing the possibility that supplements of the vitamin could prevent or decrease the severity of SARS-CoV-2 infections.

Ethical breaches in a study on the benefits of so-called “golden rice” lead to the paper being pulled from the literature.

Nutrition scientist Guangwen Tang, who was barred from conducting human studies after an investigation found that she did not comply with ethical regulations, goes to court to save her research.

Not one to shy away from controversy, Bruce Ames has pitted himself against industry groups, environmentalists, and his peers through his work identifying DNA mutagens. And he’s not done yet.

Exposure to vitamin A in the womb influences immune system development and lifelong ability to fight infections, a mouse study shows. 

Researchers show that vitamin A deficiency can help protect mice against parasitic worm infections.

Studies on safety, efficacy, or dosing of drugs in children, or on nutritional supplements, are not run-of-the-mill.
