Burn Complex (Caffeinated)


* Key Metabolic Boosters

* Appetite Suppression

* Vitamin B Complex

* Calm Energy




Burn Complex is a synergistic blend of metabolic enhancers designed to make weight loss programs simpler and more successful. Each serve contains a balanced blend of caffeine and L-theanine, providing an energy and metabolism boost, whilst calming the mind and nervous system. In addition, green tea extract provides specialised polyphenols, one of which is epigallocatechin-3-0-gallate (EGCG).

EGCG supports an increase in 24-hour metabolic rate, with green tea also being an exceptional antioxidant and antiviral herb1. Green tea is derived from the plant Camellia sinensis, as is black tea, oolong tea and white tea.



An interesting piece of research published in the Journal of Nutrition indicated that Green tea catechins speed up exercise-induced abdominal fat changes, which few would be disappointed about2. Guarana has been used in clinical trials—along with green tea extract—to speed up weight loss3.   



This Burn Complex Pre-Workout contains a clinical dosage of acetyl-l-carnitine per serve. This specialised endogenous amino acid shunts long-chain fatty acids into the mitochondria for energy. An additional benefit is that it donates acetyl groups for the synthesis of acetylcholine, an important chemical in the brain for concentration and memory.



Burn Complex also contains capsaicin—an extract of chilli—which has been shown in recent research to perform a number of incredible functions, including: elevate fat oxidation, boost thermogenesis, reduce appetite, reduces body fat formation and increase adrenaline levels4. This is the kind of natural plant-sourced metabolic support you want during a weight loss program!  



Burn Complex Pre-Workout contains a Vitamin B Complex, which naturally supports the citric acid cycle, which is intimately related to ATP or energy levels. In addition to this, Vitamin B Complex are often used during periods of psychological stress or increased physical activity.



This product is a game-changer that will allow you to take down weight loss goals like pins in a bowling alley. Crack open a tub of Optimum Nutrition Burn Complex today.
