Prime Nutrition Backdraft XP Review

Backdraft XP Is Prime Nutrition’s upcoming thermogenic fat-burner which features a few relatively under-utilized ingredients such as Paradoxine and Devil’s Horesewhip…

Prime Nutrition Backdraft XP



Carnitine is an amino acid that is heavily involved with the metabolism of fat for energy. It is required for the proper transport of fatty acids in the mitochondria, where they are oxidized (burned) for energy through the process known as “beta-oxidation”.

Carnitine deficiency has been shown to hinder fat-burning capacity. Because of this integral role in the fat-burning process, Carnitine supplementation is alleged to burn-fat, and while it may certainly help normalize fat-burning capacity, human studies regarding weight loss are mixed.
A 2002 study, published in “Metabolism”, found that Carnitine supplementation (1g/day) increased fatty acid oxidation rates in humans without Carnitine deficiency.

A 2004 study from the same journal found that L-Carnitine supplementation (3g/day) increased fatty acid oxidation in overweight subjects while having no effect on protein synthesis or breakdown.

However, a 2005 study, published in the “International Journal for Vitamin and Nutrition Research”, found that Carnitine supplementation failed to influence weight-loss in rats. The results of this study were in-line with an earlier (2002) study in which L-Carnitine supplementation (4g/day) failed to influence fat mass, body mass, or resting lipid utilization in moderately obese women.

A more recent (2010) study found that Carnitine supplementation did favorably influence fatty acid utilization in rats, though this study did not measure fat mass post-supplementation.

Ultimately, Carnitine does possess the mechanisms by which it “should” burn fat (via increased utilization of fatty acids), but human studies are not particularly encouraging so far.

Backdraft XP contains 1g of Acetyl-L-Carnitine per serving, more than most Carnitine containing fat-burners, but not necessarily an effective dose, except in individuals who are Carnitine deficient.


Caffeine is by far the most common ingredient among stimulant-based fat-burners because it triggers the release of Noradrenaline, a potent activator of lipolysis.

Although Caffeine possesses pro-fat-loss properties, the effects tend to fade with prolonged use, rendering it ineffective as a long-term weight loss solution on its own. However, when paired with other fat-burning stimulants, Caffeine can kick-start the fat-burning process, so it’s a useful addition to the True GRIT Thermo formula.

With 250mg of Caffeine per serving, Backdraft XP may provide a noticeable increase in alertness and perceived energy levels but, as a fat-burner, Caffeine isn’t particularly effective in the long-term.

Achyranthes Aspera

Achyranthes aspera, also known as Devil’s Horsewhip, has been shown to exert certain anti-obesity effects in mice, and this is alleged to be the result of inhibition of pancreatic enzymes (lipase and amylase).

This effect has been replicated elsewhere, but only in mice, with absolutely no human research regarding the weight-loss potential of Achyranthes aspera.

Backdraft XP contains 225mg of Achyranthes aspera which Prime Nutrition claims is an “efficacious dose”, but since no human data exists, this claim is far from substantiated.


Theobromine remains under-researched, especially with regards to fat-burning potential. Preliminary research indicates that Theobromine is a cardiac stimulant, but does not appear to have any potent psychoactive properties.

In the context of Backdraft XP, Theobromine may contribute somewhat to weight-loss, but we wouldn’t consider it a key ingredient.


Though commonly standardized for Capsaicin content alone, Capsicum also contains other compounds, collectively referred to as Capsaicinoids, which include Dihydrocapsaicin and Nordihydrocapsaicin.

A 2007 study noted an increase in fat oxidation (relative to placebo) during low intensity exercise in healthy adult males who consumed 150mg of capsaicin one hour before exercise.

A 2001 found subjects who consumed CH-19 Sweet (containing Capsinoids) had significantly higher core body temperatures and increased oxygen consumption (indicative of energy production) compared to the placebo group.

A later (2010) study, published in “The American Journal of Clinical Nutrition”, found that Dihydrocapsiate supplementation (3mg/day) caused a small but noticeable increase in the resting metabolic rate of healthy human subjects.

Capsicum is one of the few ingredients in Backdraft XP that can increase thermogenesis on its own, but the effects are not going to be extremely drastic.


Paradoxine is a standardized form of 6-Paradol, the active component of Grains of Paradise underlying its weight-loss implications.

Grains of Paradise (containing Paradoxine) has been to shown to increase metabolic rate in response to a physiological stressor (in this case cold exposure) via activation of Brown Adipose Tissue. It’s potential for weight-loss is discussed in this article.

Backdraft XP contains 50mg of Paradoxine.

The Bottom Line

Backdraft XP contains a few ingredients that may actually influence weight-loss, but also some that probably won’t. Prime Nutrition’s claims that “you will not find a more potent and result producing product” is off-base to say the least. We’ve come across many other fat-burners that will result in more significant weight-loss than Backdraft XP.
