                                Suboptimal vitamin B6 levels are quite common in some populations, with an analysis showing that as many as 24% of Americans who don't take supplements have low concentrations. While a severe deficiency is rare, not getting enough of this vital nutrient can disrupt your body's most basic functions, leading to a range of symptoms from mild to debilitating.
