Black Jax is a stimulant supplement that does nothing more than jack up your heart rate for increased energy. Of the six ingredients in the formula, five are stimulants. The sixth is thrown in there to help the other five ingredients absorb more quickly. There are plenty of people who need an extra kick of energy during the day, but this supplement packs more caffeine and stimulants than any dieter needs for an energy boost.

For the dieter that wants a fat burner, this supplement will increase heart rate and that could lead to increased metabolism, but there is no appetite suppressant to counteract the increased hunger often associated with energy boosting ingredients like caffeine. However, with 250 mg of caffeine per serving, the dieter may feel nauseous so hunger may not be a problem.

List of Ingredients


  • Yohimbine Alkaloids
  • Yerba Mate
  • Guarana
  • Kola Nut
  • Capsaicin
  • Caffeine

Product Features

Yohimbine, yerba mate, guarana and kola nut are all stimulants similar to caffeine. In some diet supplements these ingredients are standardized for caffeine content. In Black Jax there is no mention of the ingredients being standardized for caffeine, aside from the tiny 3 mg noted from kola nut. This doesn’t mean the stimulants are any less effective than caffeine. As a matter of fact, when combined they could be stronger than caffeine.

On top of the plethora of stimulants is caffeine – the mother of all energy supplements. With 250 mg of caffeine per dose, this supplement will cause negative side effects in a large portion of the dieting population. Take into consideration the fact that over the counter anti-sleep medications contain just 200 mg of caffeine and those tend to cause nervousness and jitters.

Capsaicin is an extract of cayenne pepper. This ingredient is added to increase the absorption of other ingredients. There is some evidence that cayenne pepper has some thermogenic properties.

Black Jax is a stimulant by every definition of the word.

The heart and blood pressure are affected by caffeine intake and that could mean the dieter feels chest pains, nervousness, jitters and nausea after taking strong stimulants.
