Ingredients Label

Active Ingredients

Chromium

Chromium is an essential mineral for humans.

It’s been shown to assist with fat-loss by regulating blood sugar levels, as well as supressing appetite (1, 2).

An effective dose is 500-1,000 micrograms.

CLA

Conjugated linoleic acid, or CLA, is a fatty acid.

Research shows that it may improve fat oxidation, even while sleeping (3).

An effective dose is 3-6g.

Acetyl-L-Carnitine

L-Carnitine is an amino acid that may have fat-burning effects.

It’s been shown to increase insulin sensitivity, as well as boost concentration levels in those with fatigue issues (4, 5).

The effective dose is 2,000mg.

Green Tea

Green tea extract is well-known for its fat-loss effects.

Research has shown that when taken before exercise, green tea assists increased fat oxidation by up to 17% (6).

The effective dose is about 500mg of extract.

Paradoxine

Paradoxine is a branded version of a spice called “Grains of Paradise”.

It’s been shown to increase energy expenditure, but this effect has only been observed when subjects were exposed to cold conditions (7).

Paradoxine may also have a positive influence on testosterone levels, but this is yet to be confirmed.

Who Takes It?

Atheltes wanting a stimulant-free supplement to assist with fat-loss may enjoy using QuadraLean.

How to Take

Take three capsules twice daily, 30-60 minutes before meals.

Do not exceed 6 capsules in a 24 hour period.

Side Effects

Paradoxine may interfere with pharmaceuticals – consult your doctor before taking QuadraLean at the same time as any other medications. It has also been loosely linked to anti-fertility effects in females.

Pros

Stimulant-free
Suppresses appetite
Improves concentration while dieting.

Cons

Doses are on the small side
Small number of servings per bottle
Worrying side effects to do with female fertility.

Conclusion

QuadraLean is a simple fat-burner that contains no caffeine or other stimulants.

It combines effects to suppress appetite, improve concentration, and boost fat oxidation, for a quicker and easier dieting experience.

Unfortunately, the doses of most ingredients are on the lower end, at less than half the clinically effective doses for all except paradoxine.

This could be made up for by taking extra capsules, but with the possible side-effects from paradoxine, this may not be a great idea.
