How many ingredients does it take to make a powerful fat burner?

Five? Seven? Twelve?

According to RSP Nutrition, just four when they came out with Quadralean.

The fat burner claims to have scientifically researched ingredients capable of helping you burn fat while preserving lean muscle. Hence, the name.

3) Ingredients of RSP Quadralean

Quadra Lean includes the following ingredients:

  • Chromium (as chromium polynicotinate (ChromeMate®)): Chromium is a mineral known to directly affect our appetite, letting us feel full for longer and reducing the risks of hunger pangs or overeating.

  • Innobio CLA 60% (Conjugated Linoleic Acid): CLA is known as a fat burner that also preserves lean muscle mass.

  • Acetyl-L-Carnitine: This is the upgraded form of L-Carnitine in that it funnels fatty acids to our cells and burns them off as energy. It also has some muscle preservation benefits similar to CLA.

  • Green-Tea Extract (50% EGCG)(leaf): This is one of the most potent fat burning ingredients in the industry, with plenty of studies to prove it.

  • Grains of Paradise Extract ((Aframomum melegueta) (Paradoxine®): More of an appetite control ingredient, but a fancy one at that.

Other inactive ingredients: Gelatin, dicalcium phosphate, plant cellulose, magnesium stearate, and silicon dioxide.

4) Does RSP Quadralean Work?

We have firm reason to believe that QuadraLean, if nothing else, works well as a metabolism booster and appetite control supplement.

The ingredients are premium or standardized, the doses are mostly on point, and there is clear evidence of synergy.

The only questionable part is whether CLA will work as intended since it often needs over a gram to have any positive effects to our metabolism and muscles, at least that’s what most studies say.

However, the ingredient does come in as the branded Innobio, so maybe there’s a chance that it’s much more bioavailable and more potent than standard CLA.

Pros & Cons

5) RSP Quadralean: Pros and Cons


  • Apt doses per ingredient
  • No fluff
  • Appetite management and metabolism booster
  • Super cost-effective
  • Premium ingredients
  • Not sure if CLA works as intended

Where to Buy?

6) Where to Buy RSP Quadralean

You can buy QuadrLean from the official RSP Nutrition website or from other online supplement retail stores.


7) RSP Quadralean Cost

The 90-capsule bottle (30 servings) costs $19.7. Opting for the subscription will bring it down to $16.97.

For 150 capsules, it’s at $24.97 and a subscription will bring it down to $21.22.


8) Directions For Taking RSP Quadralean

Take three capsules on an empty stomach twice daily. For best results, take 30-60 minutes before meals with the first serving before breakfast and the second serving before exercise. Do not exceed 6 capsules in a 24-hour period.


9) Our Final Take On RSP Quadralean

QuadraLean’s formula is definitely lean, but also effective.

Adding ingredients that are not only known to help with weight management, but also branded or standardized definitely makes the supplement feel premium and well-researched.

The angle RSP Nutrition went with QuadraLean is mostly about appetite management plus an extra metabolism boost, and we think the supplement works as intended.

The only questionable benefit is whether CLA can actually do something worth noting or if it’s just here to make the supplement more expensive.

Regardless, CLA is a quality and must-try weight management supplement that won’t cost an arm and a leg, unlike the newer formulas out there.
