Leanfire Ultimate Review – Fires Up the Energy, Sustains Cognitive Focus

Leanfire Ultimate Review

The “uncommon athlete.”

Striving for “unconventional goals.”

These are the sorts of customers that Leanfire Ultimate seems to appeal to, based on their ad copy. Which can be interpreted in two vastly different ways: 1) athletes who are uncommonly, unconventionally oriented towards success (the likely meaning of Leanfire’s statement), or 2) athletes who are complete weirdos; freaks of nature that should be locked in cages.

This is the problem with vaguely worded advertisements: They’re highly vulnerable to reasonably intelligent smart asses (like some supplement reviews I know). Having said that, Leanfire Ultimate speaks in a clearer, more straightforward manner when it comes to what’s actually in their formula, which actually looks purdy good.

How good?

Let’s read the Leanfire Ultimate review to find out.

About Leanfire Ultimate

Manufactured by Force Factor, Leanfire Ultimate is a “Powerful Thermogenic” fat burner supplement that mixes caffeinated fat burners with natural nootropics for a clean, energized experience. Well, not super clean, judging by those capsules. Formula notes:

  • Nootropic Fat Burners: And not to mention pre-workout exercise performance. Leanfire Ultimate ambitiously targets brain and body benefits in this hybrid stack.
  • Premium Ingredients: Across the board, Leanfire Ultimate supplies exceptional quality fat burners and nootropics, potent herbal extracts and compounds.
  • Double Weight Loss: Or so they say. To which we say: What are you smoking over there at Force Factor? (And how can we get some??)

Leanfire Ultimate promises to “double your weight loss” with their Thermovigilance 2x Weight Loss Complex.

To which we say, “What what whhhaaaaat???”

Leanfire Ultimate bases this 2x more weight loss claim on their star ingredient Verilean Green Coffee Bean Extract. However, you can’t necessarily apply research on a single ingredient to an entire supplement. So, we’ll need to dispel that notion right way: Leanfire Ultimate can’t accurately claim to double your weight loss.

Now that we’ve got that out of the way, let’s check out what the formula actually might do.

Leanfire Ultimate Review: Ingredients

Leanfire Ultimate’s ingredients divide into two non-proprietary blends. (Props for the non-props, Leanfire.) And those blends are:

Thermovigilance 2x Weight Loss Complex

Again, the “2x Weight Loss” statement holds no water. Having said that, the ingredients in this blend look pretty damn good.

Green Coffee Bean Extract (as Verilean) – Green Coffee Bean extract tops our BIG List of Fat Burners for its CGA content. CGAs, or chlorogenic acids, boost fat loss by helping regulate energy metabolism and blood sugar levels.

Caffeine Anhydrous – The real coffee bean extract: Caffeine. Believe it or not, this rampant drug possesses fat burning benefits when used appropriately. And Leanfire Ultimate uses it kind of appropriately, jacking the levels up pretty high to 250 mg. Roughly 2.6 cups of coffee per serving here.

L-Theanine – Smart, nootropic addition. And a much-needed complement to Leanfire Ultimate’s caffeine. L-theanine reduces caffeine’s jittery side effects while maintaining the energy and focus benefits. Granted, the correct caffeine to L-theanine ratio is 1:2 but we’ll take this 1:1 setup, too.

Cayenne Extract (as Capsimax) – This fiery pepper does two things: spikes thermogenesis and suppresses appetite. Both of which benefit fat burning, making cayenne one of our Best 5 favorite fat burners.

Black Pepper Extract (as BioPerine) – Another two-for-one ingredient. BioPerine both benefits fat burning and enhances nutrient absorption, boosting Leanfire Ultimate’s overall bioavailability.

And now onto the second blend batch:

Adaptogenic Cognitive Enhancement System

An interesting fat burning blend, assisting with L-theanine in reducing the negative effects of caffeine. This Adaptogenic Cognitive Enhancement blend opens with perhaps the best adaptogenic herb: Rhodiola rosea, a powerful, stress-reducing botanical. And at a fairly powerful dose: 300 mg. Great for maintaining muscle gains and a clear mind.

Whereas the remaining ingredients involve:

  • Cocoabuterol – Or cocoa seed extract, an antioxidant fat burner and energy booster.
  • TeaCrine – Or theacrine, a caffeine-like compound that may even out caffeine’s effects.
  • Rauwolfia vomitoria – Or wolf vomit… okay, not really. This unique herb may improve mood and behavioral cognitive disorder.

Formula Analysis

Billed as Force Factor’s “most premium thermogenic yet,” Leanfire Ultimate does impress straight out of the gates with its ingredient choices, nootropic hybrid design, and non-proprietary. And not to mention the smart L-theanine addition to offset Leanfire Ultimate’s hefty caffeine dose.

So, how is all this supposed to work towards fat loss?

Leanfire Ultimate’s formula seems to work a number of ways:

  • Increased thermogenesis – boosting the body’s fat metabolism efforts.
  • Enhanced energy – via caffeine and theacrine; providing a PWO edge.
  • Appetite regulation – reducing those pesky sugar cravings and binge eats.
  • Stress management – assisting with exercise performance and cortisol resistance.

Always celebrate your successes.

As a result, Leanfire Ultimate may deliver long-term fat loss benefits in addition to immediate boosts on energy, mood, and exercise performance. As such, this isn’t a supplement to simply consume and sit down. You’ll need to be moving and grooving while supplementing Leanfire Ultimate.

And you’ll need to keep your expectations in check: double weight loss is not a realistic goal.

Nor does it make much sense: does it also double weight loss for people with extremely hot burning metabolisms? That’s too much weight loss. Sounds like a Stephen King horror novel.

Even so, despite this bogus claim and the junky, FD&C colored capsules, Leanfire Ultimate provides a decent formula for fat loss.

Leanfire Ultimate Benefits

In addition to double weight loss, Leanfire Ultimate promises:

  • Powerful Thermogenesis
  • Clear Focus and Concentration
  • Incredible Energy

And given the supplement’s emphasis on gym performance and lean muscle mass, Leanfire Ultimate orients its fat burning benefits towards the training athletes. As such, Leanfire may double as a pre-workout supplement stack, especially with its fairly intense caffeine content. But will it double your weight loss? Again, no.

Who Takes It?

“For the Uncommon Athlete.” As we pointed out, Leanfire Ultimate aims towards the bodybuilder community, boosting energetic exercise performance and lean muscle growth. At the least, with ingredients like Rhodiola in the formula, Leanfire seems focused on ergogenic gains as much as thermogenic fat loss.

Any Side Effects?

No side effects reported. Yet, Leanfire Ultimate has essentially no reports. At time of writing, the Amazon customer reviews are non-existent. Elsewhere, the customer reviews are also sparse. So, only time will tell if this is a risky supplement or not.

To be frank, we don’t expect any side effects with this supplement. Unless you’re particularly sensitive to caffeinated stimulation. In which case, consume with caution.

Leanfire Ultimate Review Summary


  • Premium, Potent. Force Factor dishes out some hot, potent fat burners here.
  • Transparent. Leanfire Ultimate proudly displays its individual ingredient dosages.
  • Nootropic Edge. The dual emphasis on body and brain help overall performance.


  • 2x Loss Claim. For lack of a better acronym, this claim is complete BS.
  • Junk Caps. The capsules need to trim off all the nasty colorants and additives.
  • Expensive. Those premium grade ingredients come at a premium cost.

Pricing and Where to Buy

  • 1 Bottle (1 month): $79.99
  • Available online and in retail stores

You can buy Leanfire Ultimate from Amazon as well as other online retailers, with Amazon, of course, being one of the cheaper options.

Final Word on Leanfire Ultimate

Leanfire Ultimate stacks premium grade fat burners and nootropics, displaying all of its ingredients on a non-proprietary label. And the dosages we see look good across the board. If you’re willing to get over the high price and crappy capsules, then Leanfire Ultimate may make for a solid fat burner supplement and smooth caffeine buzz.
