Tap the Fat
Fat is the body’s most abundant energy reserve. RunStrong’s research backed ingredients optimise fat burn, and combat the causes of fat retention. By boosting energy levels they also help you push harder and run further, increasing calorie burn.
The L-Carnitine in RunStrong helps muscle cells metabolise fat, the body’s most abundant energy reserve. It also assists in the removal of toxins. Read the research…
Mitochondria are the engine room of your muscles. L-Carnitine plays a key role in transporting long-chain fatty acids across the mitochondrial membrane.
Vitamin D has been shown to reduce the formation of new fat cells, suppress excess fat storage and control appetite via supporting normal serotonin levels. Read the research…
Curcumin (especially when enhanced by piperine) can suppress inflammatory markers that play a role in obesity and excess weight gain, reduce fat accumulation and improve insulin sensitivity. Read the research…

Take Your Running To The Next Level
Pace, distance and frequency - these are the factors that determine your progress as a runner. RunStrong is engineered to support you at each step, enabling you to smash your running goals without trashing your body in the process.
More Power
Pushing harder increases aerobic exertion and drives fitness. RunStrong's nutrients are lab proven to increase VO2 Max, extending aerobic capacity and boosting power output so you're charged with energy every time you head out.
More Distance
RunStrong puts more fuel in your tank by tapping your most abundant energy source - your fat reserves - extending stamina while reducing lactic acid build up. Meanwhile the anti-inflammatory ingredients combat aching and soreness, minimising discomfort and freeing you to keep pushing on.
More Often
By minimising muscle damage, optimising recovery and protecting bones and joints, RunStrong keeps DOMS at bay and builds resistance to injury, helping you stick to your training schedule and enjoy your running to the max.

Muscle Damage

Creatine Kinase is an indicator of muscle damage. Studies show up to 69% reduction with curcumin supplementation.

The Curcumin C3 Complex® in RunStrong is a highly bioavailable combination of 3 curcuminoids for enhanced effectivness.


A study by Nottingham University of 15 athletes demonstrated a 35% boost in endurance and a 30% drop in Lactic Acid build up with L-Carnitine supplementation.

RunStrong uses Carnipure®, a patented, premium grade L-Carnitine backed by multiple peer reviewed studies.

How it Works
RunStrong's unique, uncompromising formula combines 5 competition proven, best of breed ingredients in a single supplement.
Carnipure® is a research proven, premium grade of L-Carnitine Tartrate - an amino acid essential to fat metabolism. It is used extensively by top level athletes to optimise energy availability, extend endurance, reduce lactic acid build up, boost VO2 Max and accelerate recovery.
Curcumin C3 Complex®
Curcumin is a powerful anti-inflammatory as well as a strong antioxidant. The C3 Complex in RunStrong combines 3 curcuminoids to ensure maximum bioavailability and optimised recovery.
Vitamin D
Vitamin D strengthens bones and joints, combating stress fractures, shin splints and long term wear and tear. Studies show it also benefits immunity and supports muscle function.
Iron Bisglycinate
Runners are prone to iron depletion due to foot strike hemolysis. Iron Bisglycinate is highly bioavailable yet gentle on the body. Healthy iron levels support oxygen uptake and aerobic performance.
A premium form of piperine, BioPerine® is a bioavailability enhancer that maximises nutrient absorption. It has been demonstrated to increase curcumin absorption by up to 2,000%.
