There are plenty of diet and workout supplements around that make claims but do they provide any evidence to back it up? Many don’t. All the ingredients in Capsiplex Sport have been tested in clinical trials and reported in many research papers.



In a study with University of Oklahoma, subjects took Capsiplex or a placebo before exercising.

When they took Capsiplex results showed:

  • 3x more calories burned before exercise
  • 3% more calories burned during exercise
  • 12x more calories burned for up to 1 hour after exercise

An EXTRA 278 CALORIES burned in total on average

They also had a 7.5% greater oxygen uptake during exercise and greater air flow after exercise than those taking the placebo.  With more oxygen reaching the muscles this means greater endurance, strength and a better recovery time ready for the next workout.



The main ingredient in Capsiplex Sport is capsicum extract, containing capsaicinoids. Capsaicinoids are found in a number of natural plants but the most effective is from the chilli pepper, known as capsaicin.

Research scientists over the years have found a number of important benefits to the human body when taking capsaicinoids:

  • increased energy
  • decreased body fat
  • raised metabolism


There have been many articles about the effectiveness of the ingredients in Capsiplex Sport, in particular chilli.

Richard Bloomer1, a researcher at the University of Memphis, published a white paper in 2003 where he talks about some of the clinical research on the effects of taking capsicum extract. He reports that results of trials showed an energy expenditure that was more than 200 calories higher than for people taking the placebo. Not only that, but the Capsimax beadlet meant there was no ‘burn’ from the chilli.

Research by Lejeune et al (2003)2 and Yoshioka et al (1998)3 showed an increase in fat oxidation when supplementing with red pepper.

Lim K et al (1997)4 found it increased carbohydrate oxidation in runners at rest and during exercise.


The other natural ingredients that make up its unique blend have been researched as well.


A study at the University of Maribor5 found L-arginine was effective in enhancing physical performance and improving muscle tolerance to hard work.

This supported a previous study by Campbell et. al6 who found l-arginine supplementation positively affected trained adult males bench press and peak power performance.

Although the body can make L-arginine, during hard exercise it becomes depleted because the body can’t replace it quickly enough.


American scientists Graham and Spriet7 found that studies on endurance athletes taking various doses of caffeine and placebos showed that caffeine had an effect on endurance.

However this was only the case at the lower doses. In fact, the high doses of caffeine had no effect on enhancing physical performance at all, and led to more adrenaline.

For this reason the amount of caffeine found in Capsiplex Sport is only the same amount as in a large cup of coffee – higher caffeine levels would not improve results but could increase side effects.

Many studies have also shown a relationship between caffeine and weight loss. A 6 month study of 167 participants8 found daily consumption of a supplement containing caffeine promoted body weight and fat reduction without significant side effects.


Research into the active component of black pepper, piperine, found that it increases bioavailability – the proportion of a substance that is released into the body’s circulation. This applies to active compounds found in herbs as well as certain drugs9.

The inclusion of piperine in Capsiplex Sport helps boost the effect of the other ingredients, making them easier for your body to process and use.


“Capsiplex is a clinically proven supplement that contains a proprietary blend of Capsimax capsicum extract (from peppers), caffeine, piperine (from black pepper) and niacin (vitamin B3).

In a clinical study conducted at the University of Oklahoma, Capsiplex was shown to help participants burn an average of 278 more calories before, during and after exercising on a treadmill for one hour.

This is because Capsiplex works to increase resting metabolic rate and energy expenditure, as well as burn carbohydrates and fat.

Studies on Capsiplex have shown that it has antioxidant effects; lowers blood cholesterol levels, blood triglycerides and glucose levels; and reduces fat accumulation in the liver. It also improves exercise endurance and performance, so you can exercise more without feeling extra exertion. In addition, [it] boosts oxygen uptake after exercise to make recovery faster.

Capsiplex’s patented blending system and pH-sensitive outer coating gives users the maximum effectiveness of a highly concentrated capsicum extract without any irritation to the mouth or stomach.

The coating only releases the Capsimax blend in the high pH environment of the intestines where it is completely broken down and absorbed, ensuring there is no burning during bowel movements. This is a different system used than most hot pepper supplements, many of which tend to cause pain or discomfort with little effectiveness.”


Using natural ingredients that have been proven to work by many clinical studies over the years, you’ll feel safe in the knowledge that there is a lot of sound, scientific evidence that Capsiplex Sport really works.

Just take one Capsiplex Sport a day before you exercise and feel yourself energised like never before! Let the thermogenic effects of chilli allow you to work harder, longer and better for a toned body, ripped abs and superb muscle pump.

Capsiplex Sport is a safe, effective pre-workout supplement and you’ll see the results in no time!


Capsiplex Sport is clinically proven to increase your energy, strength and focus, and to help you burn more calories. Your workouts won’t know what’s hit them.
