Metabolic health is the foundation of how the body produces energy, processes nutrients and maintains its internal equilibrium. After 40, shifts in hormonal signaling, mitochondrial efficiency and body composition can alter the way metabolism functions — not dramatically, but gradually, in ways that accumulate over time. Understanding these changes is the first step toward supporting them intentionally.

Our metabolic category brings together products that have been editorially reviewed for their formulation quality, ingredient transparency and alignment with the physiological processes that underpin energy production, blood sugar regulation and cellular vitality. Each product is assessed independently, with attention to both what the science supports and what remains under investigation.

Topics Covered

  • Cellular energy production and mitochondrial health
  • Blood sugar balance and glucose metabolism
  • Thermogenesis and the body's natural heat-producing processes
  • How metabolic function evolves with age
  • The relationship between body composition and metabolic rate
