Fat burners are supplements that claim to increase fat metabolism, burn more calories, impair fat absorption, increase fat oxidation during exercise, thus increasing the rate of weight loss.

Sounds great, right?

The tricky part is that many of these big claims associated with fat burners fail to follow through, particularly if an individual isn’t following a healthy diet and lifestyle alongside taking a fat burner.

Fat burners exist to optimize the fat burning process alongside a diet and lifestyle that is also catering to a fat loss goal (reducing calorie intake and increasing calorie expenditure).

Additionally, many fat burners are expensive and ineffective, making the weight loss supplement industry a difficult area to navigate.

Though this article is here to help, providing you will all the information you need to know about the two most effective fat burners and how they work as a duo - Forslean and black pepper extract, both key ingredients in the best fat burner on the market, Burn Lab Pro.

So, what are these two key ingredients and how do they work?

What is ForsLean?

ForsLean is an advanced form of Coleus forskohlii, a natural substance extracted from the root of the coleus plant.

The coleus plant is part of the mint family and is native to India, Nepal, and parts of Southeast Asia. This plant has been used for centuries in Ayurvedic medicine, the ancient Indian medicine system.

Forskolin is thought to have a multitude of medicinal properties, though most notably potentially helping to treat obesity.

One small study that was published in Obesity Research investigated the effect of Forskolin on a selection of 30 overweight or obese men compared with a placebo.1 At the end of the 12-week study, it was found that the men who took forskolin achieved greater fat loss compared to the placebo group.

Additionally, increases in lean muscle mass and testosterone were also found in the forskolin group.

These results have not been reflected in many other studies, though the initial findings are promising.

What is Black Pepper Extract?

Black pepper is one of the most popular spices on the globe, with most people considering it an absolute kitchen staple.

Black pepper is also considered to be the “king of spices”, which is likely the reason for its use in Ayurvedic medicine due to the benefits of the plant compounds.

Black pepper is also thought to drive fat loss when combined with other certain fat burning ingredients, which is why it's often paired with other ingredients to enhance absorption and bioavailability.

Let’s explore the benefits of Black Pepper Extract combined with Forslean for fat loss!

ForsLean and Black Pepper Extract: How They Work for Fat Loss

ForsLean and black pepper extract are two key ingredients in Burn Lab Pro, one of the most effective fat burners on the market.

As mentioned, ForsLean is an advanced form of Coleus forskohlii, an Ayurvedic herb that provides active forskolin. As we have also established, there have been a couple of interesting studies done on the effects of forskohlii on fat loss, which look promising.

ForsLean, found in Burn Lab Pro, triggers certain hormones that work to boost fat breakdown, fat burning, and muscle growth.

When used in conjunction with a good diet and regular exercise, ForsLean can really enhance and optimize your fat loss and muscle gains.

When it comes to the use of black pepper extract in Burn Lab Pro, it mainly works to boost nutrient absorption, thus helping the whole formula work even better.

In addition to enhancing the effectiveness of the formula, Burn Lab Pro’s BioPerine Black Pepper Extract also works as a thermogenic.

Thermogenesis is a rise in core body temperature, which accelerates calorie burning, thus enabling you to burn more fat.

So, it seems like ForsLean and Black Pepper Extract make a very effective duo when it comes to enhancing fat loss. However, what else does Burn Lab Pro offer?

The Bottom Line

While ForsLean and Black pepper extract make the perfect fat loss duo, the other ingredients contained in Burn Lab Pro also work synergistically to burn more fat, promote lean muscle growth, and improve training performance and recovery.
