Rebel Performance Focus Fury Review

Focus Fury is a Nootropic supplement by Rebel Performance which provides a number of pretty standard non-stimulant cognitive enhancement ingredients as well as Caffeine and Theacrine, making it more geared towards those who seek some instant energy as well.

Alpha GPC

Alpha GPC is considered the most bioavailable form of Choline and is capable of increasing Acetylcholine levels in the brain.  Acetylcholine, for those unfamiliar, is a neurotransmitter which plays an integral role in various aspects of cognitive function and muscle contraction.

In addition to improving cognitive function, Alpha GPC has been shown to increase power output during resistance training.

Unfortunately, Focus Fury contains just 100mg of Alpha GPC per serving, so multiple servings would be needed to achieve a clinical dose of Alpha GPC.

Tyrosine

Tyrosine is an amino acid that is used to create Dopamine and Noradrenaline, two neurotransmitters associated with focus and mood.  For this reason, Tyrosine is often alleged to improve focus, but research indicates that it is only capable of preserving focus during times when Dopamine and Noradrenaline levels are compromised.

Focus Fury contains 333mg of Tyrosine per serving, far less than what can be considered a clinical dose.

Theanine

Theanine is a unique, non-dietary amino acid which has been shown to reduce anxiety as well as synergistically enhance the effects of Caffeine.

Ultimately, there is really no reason not to take Theanine along with Caffeine, and we discuss that relationship further in this article.

Focus Fury contains 66mg of Theanine per serving, technically within the clinical range but not necessarily the most effective dose.

Huperzine A

Huperzine A is an Acetylcholinesterase inhibitor, meaning it inhibits the enzymes responsible for breaking down Acetycholine.  Recall from above that Acetycholine is a neurotransmitter which controls cognitive functions as well as muscle contraction.  By preventing it’s breakdown, Huperzine increases Acetylcholine levels, potentially complimenting the effects of Alpha GPC.

Focus Fury contains a standard 50mcg of Huperzine A.

Vinpocetine

Vinpocetine is a truly unique molecule, capable of increasing blood flow specifically to the brain.  For this reason it is often sold as a cognitive enhancement supplement.  To be fair though, there hasn’t been enough research regarding the cognitive benefits of Vinpocetine in healthy individuals.  We discuss Vinpocetine more in-depth in this article.

Focus Fury contains 2.5mg of Vinpocetine per serving, a relatively low dose as far as most nootropics are concerned.

Caffeine

Focus Fury contains three forms of Caffeine, but they all basically serve the same purpose.  Caffeine triggers the release of neurotransmitters like Dopamine and Noradrenaline which are responsible for the alert, energized feeling you get when you consume Caffeine.

Focus Fury contains 67mg of Caffeine per serving, not a particularly high dose, so many individuals may need at least two servings to feel the effects.

Theacrine

Theacrine, like Caffeine, is capable of increasing perceived energy but through slightly different mechanisms.  We discuss Theacrine much more in-depth in this article, but to make a long story short, it can potentially provide users with energy.

Rebel Performance does not disclose the precise dose of Theacrine in the Focus Fury formula, making it a little more difficult to predict how it might affect the average user.

Rhodiola Rosea

Rhodiola is considered an Adaptogen, meaning it has mechanisms by which it helps the body/mind adapt to stress.  Unlike so many other alleged Adaptogens, Rhodiola has actually been researched quite extensively to date.

It has been shown to not only reduce stress and fight fatigue, but also to enhance exercise endurance.

Unfortunately, Focus Fury no doubt contains far less Rhodiola than what can be considered a clinical dose, so the benefits mentioned above are far from guaranteed.

Phosphatidylserine

Phosphatidylserine is a phospholipid that is an important component of cell membranes.  It is often sold as a cognitive enhancement supplement, but research indicates that it may only help to preserve cognitive function during instances of cognitive decline (such as Alzheimer’s).

However, Phosphatidylserine has been shown to reduce stress, both physical and subjective measures, in multiple studies in healthy human subjects.

Is Focus Fury Safe?

Focus Fury is pretty safe, yes.  The only stimulants are Caffeine and Theacrine but they are at pretty low doses…Certainly much less than what could potentially cause negative side effects.

The Bottom Line

Focus Fury contains all the right ingredients, but some of them are severely under-dosed.  The stimulant level is pretty low, leaving the option to take multiple servings daily, but there are other nootropics out there which provide more bang for your buck.
