F-BRN Komplex is a stimulant-free fat-burning supplement manufactured by German-based company, GetFit Fitness.
GetFit Fitness claim that F-BRN Komplex:
- Will boost your metabolism.
- Can make you more efficient at using energy from fat cells.
- Will reduce your food cravings.
So let’s find out a bit more, shall we?
Here’s the ingredient profile for F-BRN Komplex:
L-carnitine tartrate is critical for your body’s energy production because it helps to transport fatty acids to the mitochondria in your cells. These mitochondria are then able to burn the fatty acids for energy.
Your body is able to synthesize L-carnitine from the amino acids lysine and methionine.
L-carnitine also occurs in meat and fish so, consequently, vegans or vegetarians may not be able to obtain enough of it.
Because L-carnitine helps transport fatty acids into your cells for energy, you may think that it would help you to lose fat.
In reality though, the results of both human and animal studies are fairly inconclusive.
A clinical trial on a group of women who exercised four times per week showed that those who took L-carnitine experienced no more weight loss than those who didn’t.
However, a series of studies, mostly in obese individuals, found that participants lost an average of 1.3kg more weight when they took L-carnitine. (1)
Green Coffee Extract
Green coffee bean is simply the coffee bean in its unroasted state. Surprisingly, it doesn’t contain any caffeine.
The active ingredient in green coffee bean is chlorogenic acid. Chlorogenic acid helps your body to prevent carbohydrates being absorbed from your digestive system. It can also help you decrease both your visceral fat and levels of the hormones that cause obesity. As a consequence, this can help reduce your body weight. (2)
Green Tea Extract
Green tea contains caffeine and also epigallocatechin gallate (EGCG), which are both particularly effective fat-burners.
Caffeine stimulates your release of adrenaline. EGCG helps to amplify the fat-burning effects by decelerating your body’s breakdown of adrenaline.
Researchers have verified that green tea supplements can accelerate your metabolic rate by as much as 4% and help you burn up to 16% more fat for as long as 24 hours after taking them.
One clinical study discovered that when participants took a green tea supplement every day for 12 weeks, they achieved an average weight loss of 1.3kg. This weight loss wasn’t dependent on the dose taken. (3)
The tropical fruit, garcinia cambogia contains hydroxycitric acid (HCA). This works to suppress the function of citrate lyase, an enzyme which helps to create body fat.
A research study demonstrated that if you take garcinia over a period of two to twelve weeks it may help you lose up to 1% more of your bodyweight. (4)
How Does F-BRN Komplex Work?
F-BRN Komplex is designed to accelerate your metabolism. When your metabolism works at a faster rate, you’ll burn more calories, even while you’re at rest.
Some of the ingredients in F-BRN Komplex act as appetite suppressants. These help you to feel full and avoid overeating.
GetFit Fitness also claim that F-BRN Komplex directly stimulates fat breakdown, helping you to use your stored fat more effectively for energy.
Additionally, F-BRN Komplex doesn’t contain any stimulant ingredients. This is particularly good news for people that are intolerant to caffeine and other stimulants. However, the absence of stimulants may tend to make fat burners less effective.
Side Effects of F-BRN Komplex
GetFit Fitness claim that F-BRN Komplex causes little or no side-effects.
This claim is likely to ring true because it contains no stimulants and, also, because the doses are not too heavy.
Moreover, clinical studies have found most of the ingredients to be safe at these doses. A question mark does remain over garcinia cambogia though, which can be tough on your liver.
How To Take F-BRN Komplex
GetFit Fitness recommend that you should take three capsules per day. As a bottle of F-BRN Komplex contains 90 capsules, this should last you for about a month.
They also recommend that you should spread the three doses as evenly as possible throughout the day to get the maximum benefit.
Where To Buy F-BRN Komplex
A bottle of F-BRN Komplex will set you back about £29.00 in the UK. This makes it a fairly low-budget fat burner, suitable for people that want to avoid caffeine and other stimulants.
You can buy F-BRN Komplex on GetFit Fitness’s website here as well as some other online stores.
Pros and Cons of F-BRN Complex
Here’s a quick summary of F-BRN Komplex’s positives and negatives:
- Competitive price
- Contains green tea, one of the best fat-burning ingredients.
- All the ingredients are natural.
- Doesn’t contain glucomannan.
- It’s missing cayenne pepper.
- The fat-burning effectiveness of carnitine remains unproven.
Unfortunately, F-BRN Komplex doesn’t contain glucomannan, which is an excellent ingredient for a fat burner. It also contains no cayenne pepper, which is also incredibly effective.
Clinical studies haven’t shown that carnitine is particularly beneficial for helping you lose fat. It only seems to be effective if you’re obese or your levels are insufficient, possibly as a result of your diet.
Carnitine and garcinia aren’t considered by experts as two of the best fat burners. Carnitine isn’t effective unless your levels are low and garcinia might be unsafe to take for long periods of time.
People who can’t tolerate caffeine may like the stimulant-free F-BRN Komplex but, in reality, most of the stand-out fat burners on the market contain stimulants.
Fundamentally, F-BRN Komplex is a solid fat burner. It could do with one or two more tried and tested ingredients, though. If it included caffeine, for example, this would make it more powerful but, consequently, the manufacturer wouldn’t be able to claim that it was stimulant-free.
If you want a fat burner that’s not too hardcore, though, F-BRN Komplex could be the one for you. As discussed, it does feature some decent ingredients. Green tea is great for an energy boost, as verified by many studies. Garcinia cambogia is an effective appetite suppressant, but it’s not as good as glucomannan. Furthermore, garcinia can be tough on your liver.
We don’t believe that GetFit Fitness have designed F-BRN Komplex to be the most explosive fat burner on the market. However, it does indeed contain some great ingredients, albeit at fairly light doses.
And with its modest price tag, F-BRN Komplex could be just the thing for you if you’re just looking for a mild fat burner to help you on your quest for a more trimmed physique.
