Metabolism is the body's constant work of turning food into fuel, and this focused Priority One collection is dedicated to it. Several formulas feature chromium, a trace mineral that contributes to normal macronutrient metabolism, combined with plant extracts and supporting vitamins and minerals in capsule and tablet form. Each blend takes a slightly different route, giving practitioners and informed shoppers room to compare ingredient panels side by side. They are meant to sit alongside balanced meals and regular activity, not replace them. Every formula comes from the brand's NSF-certified facility in the United States, with incoming botanicals tested for identity before they enter production.
