Energize & Burn Unflavored
GNC Total Lean Advanced
Overview
GNC Total Lean Advanced Energize & Burn aims to enhance energy and metabolism, primarily leveraging caffeine and some thermogenic ingredients. While the caffeine dose is effective for energy and exercise performance, several other key ingredients like Carnosyn (Beta-Alanine), L-carnitine, Choline, Rhodiola, and Schisandra are present at doses significantly lower than those shown to be effective in clinical research. This significantly limits the overall effectiveness of the blend for calorie burning and physical performance beyond the stimulant effect of caffeine. The 'Concentrated Calorie Burning Blend' and 'High Energy Mind/Body Matrix' are proprietary in nature regarding the total blend amount, but the individual ingredient dosages are disclosed, allowing for a better assessment of their effectiveness. The inclusion of dietary fiber is a positive, but its contribution to the product's primary goals of energy and burning is indirect.
