According to research published by the National Institutes of Health, while nanotechnology can significantly enhance the bioavailability of nutrients, the long-term safety of ingesting engineered nanoparticles remains a subject of ongoing debate. This scientific uncertainty has led many consumers to question: are nano vitamins safe? The rise of 'nanoceuticals' represents both a promising frontier and a potential health concern.

Menadione, or vitamin K3, is known to cause dose-dependent oxidative damage in various cells, including endothelial cells and cancer cells. This toxicity primarily stems from its ability to disrupt cellular redox balance by initiating a vicious cycle of chemical reactions that generate harmful reactive oxygen species (ROS).
