Increase your calorie burn by up to 60%

GNC Total Lean Burn 60 is a powerful thermogenic formula that boosts energy and metabolism and is clinically proven to increase calorie burning by up to 60%. With its powerful ingredients, GNC Total Lean Burn 60 enhances cellular metabolic activity. For best results, use it along with the healthy diet and exercise programme outlined below.

Triple Strength L-Carnitine


GNC Triple Strength L-Carnitine harnesses the power of Carnitine, which transports long-chain fatty acids into cells' mitochondria, so they can be oxidised ("burned") to produce energy. Once inside the mitochondria, these fatty acids are broken down, producing cellular energy and trans-forming your unwanted body fat into energy.

GNC | Total Lean CLA


GNC Total Lean CLA (Conjugated Linoleic Acid) helps to maintain lean muscle mass. It enhances your diet, fuels energy & increases your metabolism and, as a result, is a great complement to your current diet and weight management regime.


“I believe it is important to have a proper diet and practise a healthy lifestyle. With the combination of GNC products I can achieve my goals and maintain my physique all year round.”


Change is one of the most difficult things for people to do. However, choosing GNC as your partner when making lifestyle changes can be a game shifter, as Marelize Esterhuizen, 2015 GNC Summer Slimming Challenge winner can attest to.

Marelize grew up in a health-conscious home, but at university, unhealthy eating caused her to gain a lot of weight. After completing her studies, she tried to get back into shape, but it proved more difficult than she anticipated. Then she entered the 2015 Cashing Summer slimming challenge, and she ultimately went on to win the competition.

“I entered the GNC Chasing Summer Challenge, keen to be pushed out of my comfort zone. I trained five to six times a week, gave up sugar and alcohol, and took my daily GNC supplements. The challenge made me feel fitter, stronger, healthier and happier – and when I was announced as the winner, I became even more determined to live out my newfound dream of working in the fitness-training industry.”

In 2016 she started a course as a personal fitness trainer. Juggling a full-time job, part-time studies, family and friends, and maintaining a balanced, healthy lifestyle, is not easy. However, Marelize persevered and after obtaining her certificate, she resigned from her job to become a full-time group coach and personal trainer.

From couch potato to fitness fanatic, personal trainer and GNC ambassador – not an easy feat … but, if shé could, so can you! Make the change, and commit to a healthier, fitter and slimmer you today.
