NutraSport ECA Stack

This is the original, patent protected ECA stack from NutraSport, that most other manufacturers have sought to emulate.

The active ingredients in NutraSport ECA STACK are ephedrine, caffeine and aspirine. Like other ECA-based products, NutraSport ECA STACK works by inducing thermogenesis (the production of heat), which speeds up your metabolism and burns calories. It also has an appetite-suppressing effect, so you feel less hungry and therefore eat less.

Thus, it works on two fronts:

  • thermogenesis: ‘speeding up’ you metabolism, and making you burn more calories
  • appetite suppression: making you eat less, and forcing the organism to mobilise the supplies it already posseses – ie. use up fat.

How Does NutraSport ECA Stack Work?


Ephedrine is a stimulant that works on the adrenergic receptors of the central nervous system. It has been shown to increase the level of dopamine, which is a precursor to both epinephrine and norepinephrine, which are vital neurotransmitters. Dopamine is also an important neurotransmitter around the hypothalamus, an area of the brain that is important for body arousal. Unlike caffeine, which exerts many of its benefits in muscle tissue, ephedrine appears to work primarily on the central nervous system.

Ephedrine inhibits the reuptake of norepinephrine, a hormone secreted by the medulla of the adrenal glands, that acts as a neurotransmitter. The sympathetic nervous system functions in response to short-term stress; hence norepinephrine, whose levels are boosted by ephedrine, increases the heart rate as well as blood pressure. Other actions of norepinephrine include increased glycogenolysis (the conversion of glycogen to glucose) in the liver, increased lipolysis (the conversion of fats to fatty acids) in adipose (fat) tissue, and relaxation of bronchial smooth muscle to open up the air passages to the lungs. All of these actions represent a mobilization of the body’s resources in order to meet the stressful challenge; such a response is often termed the “flight or fight” syndrome.

Basically, ephedrine keeps your body in “combat” mode for extended periods of time, facilitating weight loss through NutraSport ECA STACK.


Caffeine works by increasing free fatty-acid concentrations and adrenaline levels. This results in greater lipolysis (oxidation of fats for energy), which can drain your fat stores over time. This change in a muscle’s utilization of energy substrates can have a profound effect on fat loss. Caffeine also heightens mental alertness, which can positively affect your motivation to exercise and create the caloric deficit needed to lose body fat.

Caffeine is rapidly absorbed by the body and remains in circulation for more than seven hours. Plasma concentrations reach a peak one hour after it is consumed. It is then slowly metabolized, with a half-life of four to six hours.

Caffeine has been shown to dramatically increase free fatty-acid levels, providing the body with a fuel source that it can use instead of the glycogen stored in your liver and muscles. In fact, one (not related to Betalean Hp) study found a 100% increase in plasma free fatty acids after the subjects took 330 mg of caffeine.

At the same time, caffeine has been shown to increase adrenaline levels. This “fight-or-flight” hormone increases alertness and boosts energy levels, helping you to go through your daily tasks with less food intake. Most people experience a reduced appetite when their adrenaline levels are high, usually because they are focused on more essential tasks. With these two mechanisms, it’s easy to understand why caffeine is used in NutraSport ECA STACK, and is important for jump-starting your weight-loss efforts.


Aspirin is the popular name for acetysalicylic acid. It raises the body’s internal “thermostat,” so that the increased production of heat, which is typical of NutraSport ECA STACK, does not set off alarms in the body. This allows the ephedrine and caffeine to work in your body for a longer period of time, giving you the maximum fat-burning potential.

How To Take NutraSport ECA Stack and NutraSport ECA Stack Dosage and Administration

The recommended NutraSport ECA STACK serving is two capsules three times a day, which is the exact serving used in clinical trials. However, many people who are sensitive to stimulants have reduced the serving as low as one capsule twice a day and have still seen results.

NutraSport ECA Stack Precautions and Contraindications

As with any thermogenic weight-loss pill, you should consult your doctor before taking NutraSport ECA STACK, especially if you have a previous history of health problems.
