Scientists are raising new questions about vitamin B12 and cancer
High doses of vitamin B12 supplements may carry unintended risks, according to emerging research that challenges the nutrient's universally healthy reputation. While deficiency is well-established as harmful — impairing DNA repair and raising cancer risk — some studies now link chronically elevated B12 levels to certain cancers and worse outcomes in existing patients. The findings suggest a more nuanced calculus for supplementation than the conventional wisdom of "more is better."

Scientists create supercharged vitamin K that helps the brain heal itself
Japanese researchers have engineered hybrid compounds that merge vitamin K with vitamin A-related components, tripling the effectiveness of natural vitamin K at converting neural stem cells into fully developed neurons. The advance opens a potential new avenue for treating neurodegenerative conditions like Alzheimer's and Parkinson's, diseases that currently have no cure and limited treatment options. If the approach translates to clinical use, it could mark a significant shift in how medicine addresses neuronal loss.
